Installing an arch in a house can serve several purposes: to make the interior original and distinctive, or to visually enlarge the space. Absence door leaves and space for opening them allows rational use of the space of a compact apartment.

To decorate a room with, it is not necessary to use the expensive services of professional builders; you can make an arch yourself in doorway. And this article will come to the rescue! In it, we looked at the main questions that beginners have: what types of arches are there, what materials they are made from. Also here are step-by-step instructions for the work being performed, advice from experts - all the subtleties of the arch making process.

In what rooms can you make an arch?

Door arches will decorate an interior made in any style, because there is a wide variety of them. First of all, they differ in the shape of the opening:

• classic, representing a regular semicircle;
• made in the Art Nouveau style, elliptical configuration;
• in the “romantic” style, which are complex combinations of rounded shapes and straight lines;
• pointed upwards, made in gothic style etc.

Arches can be installed in almost all types of premises. The only exceptions are rooms intended for privacy, such as a bedroom, office or bathroom.

Eat different opinions about installing an arch in the kitchen. cause discomfort: the spread of kitchen odors throughout the apartment, noise from preparing early breakfasts while the rest of the family is sleeping, etc. But, if there is a powerful hood and the kitchen does not open into the living quarters, but, for example, into the corridor or dining room, it can be installed.

Materials

Exists a large number of materials from which it can be made. Typically, drywall, plastic or wood are used for these purposes.

Using concrete or bricks you can also decorate the doorway in an interesting and original way. But in order to make a brick arch with your own hands, you need skills in construction - a beginner cannot do this work. This process is also labor-intensive and time-consuming, which not everyone can afford.

In this article we will look at how to make plasterboard (gypsum plasterboard). This material is accessible and inexpensive; the technology for working with it does not involve the use special tools and will not be difficult even for a beginner.

How to make an arch from plasterboard?

You can buy plasterboard arches, especially since there is a huge selection of them on sale. But it’s difficult to choose a product that perfectly matches the doorway, so try making it yourself.

Despite the fact that gypsum board makes it possible to construct structures of the most intricate configurations, we will dwell in detail on the simplest and most common option: a semicircular interior arch.

The process of its manufacture consists of the following stages:

• preparation of tools and materials;
• measurements and, if necessary, preparation of the doorway;
• production of front parts of the structure;
• frame installation;
• arch installation;
• final works.

Let's consider each stage separately.

Materials

We will need following materials for making an arch:

• drywall;
• metal profiles for constructing a frame;
• fasteners;
• perforated;
• putty on drywall.

When choosing drywall, pay attention to the fact that different areas of the structure will need material different thicknesses. For the front surface, it is better to choose sheets with greater thickness to ensure structural strength. For the bottom edge, it is better to purchase thin gypsum board, which is easier to bend.

Select fasteners depending on the material of the walls in the room. For wooden walls, purchase self-tapping screws. If the design is planned for, it is better to choose dowels. They are also suitable for plaster and concrete walls.

Measurements and preparation of the doorway

Before measuring the doorway, you need to prepare it: dismantle the doors, slopes and trims, if necessary, clean and level its inner surface using beacon plastering or putty. Then, using a tape measure, we determine the height and width of the opening.

Advice! Arches are not recommended if the height of the opening is less than 2 m and the ceilings are below 2.5 m. Also keep in mind that an arch for a doorway will reduce its height by 10-15 cm.

Making the front parts of the arch

Let's look at how to make the front parts of the arch. These details must be drawn on a sheet of drywall and cut out. When performing this work, pay attention to the fact that both parts must be absolutely identical, and the semicircle of the arch must have the correct shape.

One of the popular and available ways markup is like this:

1. The width of the doorway must be divided in half - this way we get the radius of the semicircle.
2. We mark a rectangle on a sheet of drywall: its width should correspond to the width of the doorway, and its height should correspond to half the width of the doorway + 10-15 cm. Example: if the width of the opening is 1 m, then the rectangle should be 60-65 cm high. Added 10- 15 cm is the distance from the top of the doorway to the top of the future arch. It is not recommended to make this distance less than 10 cm.
3. Now let's mark the arch of the future arch. On the bottom side of the drawn rectangle, mark the middle and use various devices draw an even semicircle with a radius equal to half the width of the doorway (in our case, 50 cm). This can be done with a homemade compass, using a rope (thread) and a simple pencil (chalk).
4. Cut out the resulting blank. To do this, you can use a utility knife, a special knife for cutting drywall, or a jigsaw.
5. To ensure that both parts are absolutely identical, the first is used to mark the second.

It is not always convenient to use for marking a circle homemade compass- often when using it, the lines turn out to be uneven and asymmetrical. If you have a helper, use in the following way, which will allow you to draw a circle more accurately and evenly. To mark a sheet using this method, you need a strip of flexible but elastic material. You can use a piece of soft plinth or a strip cut from a PVC panel for this purpose.

From the middle of the lower part of the marked rectangle, draw a straight line perpendicularly upward, the length of which is equal to the radius of the circle, and mark a point there. After this, the flexible strip is applied to the sheet and bent so that it comes into contact with the marked point and the lower corners of the drawn rectangle. While one person holds the strip in place, the second person traces it.

For the end (bottom) part of the arch, mark and cut out a narrow rectangular strip with a width equal to the thickness of the doorway. To determine the length of the strip, multiply the radius of the circle by the number π (3.14). In our case: 50 cm ×3.14 = 157 cm. It is better to cut the strip with a margin, since it is much easier to cut off the protruding extra centimeters than to cut it all out again if there are not enough of them.

Making a frame

To securely install an arch in a doorway, you need durable frame. Therefore, the next question we will consider is how to make a frame for an arch. To make it we use a metal profile.

First we install the upper parts. To do this, we cut out two guides along the width of the doorway and fix them in the upper part of the slope, parallel to each other. If the doorway is located in plaster, brick or concrete wall, then we use dowels to fasten the frame elements. Wood screws are suitable for wooden walls.

Let's move on to installing the side parts. We cut out 4 side parts from the metal profile and fix them in the upper part of the opening parallel to each other. Their length must correspond to the height of the plasterboard blanks. Since the blanks taper downward, be sure to cut off the lower corners of the profile so that they do not protrude beyond the drywall.

Important! When securing the frame, make sure that the front and rear parts are parallel to each other - this will prevent subsequent distortions of the structure.

So that after fixing plasterboard sheets and a layer of putty, the structure did not protrude from the wall, the frame elements are attached at a distance of 1.5-2 cm from the edge of the opening.

Installation

Installation of a gypsum plasterboard arch consists of attaching plasterboard blanks to the frame. First, the front parts are screwed on using metal screws. The distance between adjacent fastenings should be no more than 15 cm. To ensure a tight fit to the profile, the plasterboard sheets are pre-moistened with a damp cloth, and fastening begins after they become flexible.

There are two main ways to attach the end (bottom) part of the arch. More often it is screwed using self-tapping screws with a press washer directly to the facing plasterboard parts. Less often, a special frame is built to attach it at the bottom of the structure, but this method is better to use if you plan to make an arch from fiberboard with your own hands.

Beginners often have difficulty when trying to bend drywall pieces. Therefore, let us dwell on the features of working with this material:

• the sheet is moistened with a damp cloth;
• pressing lightly, roll a needle roller over it;
• the part is placed at an angle, leaning against the wall;
• when the sheet acquires elasticity and bends under its own weight, it is given the necessary configuration.

Completion of work

After the arch elements are secured, wait 10-12 hours until the drywall is completely dry. Final works for the manufacture of an arch include leveling its surface and decorating.

To protect the corners of the arch, straighten the circumference and hide defects made during manufacturing, you can attach a special perforated corner along the lower edge.

The surface of the structure is primed, leveled with putty and sanded. sandpaper. The layer of putty should be sufficient to align the arch elements with the wall. It must be applied to the structure itself, as well as to the seams and joints.

Decorate a plasterboard arch different ways: wallpapered, painted, tiled or decorative stone, covered with decorative plaster.

Conclusion

It’s easy to make an arch in an apartment with your own hands. The same technology, as described above, is used for structures made of MDF, fiberboard or plastic.

The main thing is not to be afraid to take on a new field of activity, to apply effort and imagination! And a door arch made by yourself will certainly become a decoration of your home!

Arches have been used in architecture since the second millennium BC. At the dawn of history, they were given a special sacred meaning: going through the arch meant being born again.

Today, arches are increasing their popularity in interior design.

Interior arch performs the same functions as several thousand years ago: it gives originality and visually divides the space, simultaneously combining two rooms together.

Arches are most actively used in a wooden private house or apartment; they are usually installed in the hallway or connect the kitchen and living room.

Varieties

Arches represent a symbiosis of elegance and versatility, fit into any interior, decorate the doorway.

Variety of forms of arched structures classified as follows:

In addition, arches can be made according to individual sketches and have a fancy shape, depending on the customer’s imagination.

Interior arches made from the following materials:

1. Wooden – practical material, creating an atmosphere of comfort and warmth. Arches made of wood fit into any type of opening.
2. Drywall– characterized by plasticity and ease of installation.
3. Plastic(PVC) – easy to care for, moisture resistant, durable.
4. Mdf- aesthetic, big choice colors and textures, affordable prices.

Decorative finishing options

Interior arches made of MDF, plastic or wood are usually left in its original form.

In turn, plasterboard structures require additional decor.

Finishing performs the following functions:

• camouflage – allows you to hide installation defects;
• technical – adjustment of dimensions using decorative elements;
• decorative – gives the arch a final look in the theme of the chosen style.

A huge number of modern finishing materials allows you to achieve individuality and combinations with other components of the interior.

Let's consider most common options decorative finishing:

1. Plaster- a simple method, while the choice of textures and colors will satisfy the most demanding taste. First, the surface is puttied and primed, wait until it dries completely and apply decorative plaster. If a relief is provided, then a drawing is made on the freshly leveled layer.
2. Cork wallpaper– presented in the form of rolls or veneer tiles or cork chips. They are light, elastic, durable, and are mounted on a leveled surface using glue. Decorating the arch yourself with cork wallpaper is quite easy and will not take much time.
3. Painting. Pre-aligned plasterboard construction coated with acrylic or water-based paint, wooden - varnish.
4. Decorative rock– durable, resistant to external influences, but not cheap material. Installation is labor-intensive and requires certain skills. The stone needs to be glued to cement base after preliminary filling and priming of the vault and walls.
5. Mosaic. Made from pieces of ceramics, glass, stone, pvc panels having a wide range of shades. Based on the material used, the elements can be square, round, oval, rectangular, triangular, or any shape. Decorating an arch with mosaic designs is quite easy, you just need to use your imagination. Mosaic designs are original and unique.

As is known, modern design ideas They constantly present us with new solutions. The finishing with mirrors or textiles looks original. Frescoes will give the interior status– hand painting with paints on wet plaster.

Design Experts experimenting with shapes, creating arches with through niches or bar counters. IN last years stucco, columns and gilded details returned to fashion.

DIY arch in the hallway

Making an arch at home is not hard work, requiring minimum experience in area home renovation. Let's look at the construction method for a simple hallway semicircular arch from plasterboard. Please note that the process may differ slightly depending on the thickness and material of the walls.

We purchase materials and prepare tools

Measure the opening, make a sketch, indicating the height of the beginning of the rounding and the radius.

The best option is moisture-resistant, fire-resistant plasterboard. It is advisable to choose a wall one with a thickness of 12 mm, an arched one - 6.5 mm. For straight frame elements, a rack metal profile is required, and for the contour, a guide profile is required.

You will need short metal screws, special for drywall, as well as wood screws.

From the tools we prepare:

• roulette;
• perforator;
• level;
• jigsaw;
• putty;
• pencil;
• metal scissors.

Preparatory work

Clear the opening of paint, wallpaper, widen the opening or increase its height if necessary. Level the side walls Using putty, apply marks with a pencil.

Cut two rectangles from drywall. Apply an arc shape to the drywall using a nail or pencil tied to a string.

Do not make an excessively steep arc, especially for a narrow opening.

Then cut out the arch electric jigsaw , or a hacksaw for metal, repeat the procedure with the second rectangle. (see photo)

Frame installation

Cut four vertical elements equal in length to the height of the workpiece and two horizontal elements equal in width. Next you need to install the profiles and attach them with self-tapping screws 40-50 cm long to the walls of the opening, leaving about 1.5 cm deep on both sides.

Consider the thickness of the drywall to the structure coincides with the plane of the wall. You should start with a horizontal guide.

Assembly

Secure the drywall sheets to both sides of the frame using a screwdriver. Leave the screw heads flush with the surface.. Then measure the length of the arc and separate the profile section using metal scissors.

To bend the profile it is necessary to make several cuts along the edges, the more often, the stronger the bend will be. Secure the resulting arc to the bottom of the metal frame with self-tapping screws. Connect the guide and drywall with self-tapping screws in increments of 10-15 cm.

Lightly wet the drywall before bending. Now attach the resulting element to the arches (the cuts should be inside the structure), attach with self-tapping screws. Achieve maximum fit of the frame to the structure.

Finishing

At this stage, it is necessary to cover the edges of the drywall and joints with fiberglass mesh or paper tape, wait until dry. Apply a layer of putty and after drying sand the surface. Repeat the procedure twice, achieving perfect smoothness.

Choose the decor to suit your taste. As an example, let's give the simplest and most economical way– pasting the arch with wallpaper and then finishing the edges with a plastic corner.

Wallpaper should be chosen that is easy to care for (vinyl, bamboo, non-woven), plain or with a small complex pattern is recommended. It is necessary to cover the walls on both sides of the opening, leaving a margin of 2-2.5 cm, cut off the excess, bend the edge into the inside of the arch.

Cut a strip of suitable width and glue inside the opening.

The joint will look more aesthetically pleasing if you use a plastic corner.

Before installation it is advisable degrease the inner surface corner, then apply thin layer sealant, liquid nails or special glue, press firmly to the installation site. Lock in wait until the glue sets.

The work is completed, you can enjoy the result.

For registration doorways All kinds of arches are often used in the house. They have many advantages:

• they save space in the room, which is occupied by opening and closing doors;
• visually unite the space of the apartment, providing easy passage between rooms;
• visually zone individual rooms without the help of doors, if required by the design concept;
• make an apartment or house elegant, giving it an elegant and original look.

Basic forms of arches used in residential premises

There are different design options for the doorway, which depend on technical features both rooms, which will be separated by an arch. In particular, the determining criteria when choosing the shape of the arch are the height of the ceiling and the width of the doorway. Because some types of arches are intended only for high rooms, while to create others, the opening needs to be widened. Before making an arch in the doorway, you need to carefully take all the necessary measurements, since the success of the entire process of the upcoming installation will depend on this.

The most common types of arches are:

1. Classic (with the correct arc radius equal to half the width of the doorway).
2. In the Art Nouveau style (having a truncated arc radius that exceeds the width of the doorway).
3. Romance (rectangular arches with rounded corners).
4. “Portal” arches (arches of a simple rectangular shape, repeating the shape of the doorway).
5. Arches in the shape of an ellipse, dome, trapezoid and other arches of non-standard shape.
6. Semi-arches (arches formed by a small part of a circle of large radius).

Any arch made with your own hands or with the help of specialists is made of: brick, stone, natural wood, plywood, chipboard or fibreboard, MDF, plastic, plasterboard.

Arches made of brick, stone, concrete

Such arches in the interior look beautiful and solid, especially in the corridor or hallway, but installing an arch from these materials is not an easy task. In addition, this design is quite heavy, and this must be taken into account. Making an arch from stone or brick often requires increasing the size of the doorway, and this is sometimes problematic.

There are three main types of brick arches:

• Full, or regular (bricks are laid out in the form of a semicircle, the height of which is half the width of the doorway);
• Wedge-shaped (bricks in a special way, tightly laid in a wedge);
• Luchkovaya (bricks are laid along a truncated arc).

Manufacturing of conventional brick arch is the simplest of the three described, and the wedge one is the most complex. However, the masonry technology in all three cases is very similar, but it requires certain skills. Therefore, before making a door arch from brick, it is advisable to thoroughly study the process in theory and watch the corresponding video.

In general, installing an interior brick arch includes the following steps:

• design and production of a template for the arch of the future arch;
• installation of a manufactured template;
• laying bricks in accordance with the chosen arch shape;
• fixation of the made structure;
• deleting a template;
• final finishing of the finished arch.

It is highly advisable to take into account the experience of others and not allow typical mistakes when making a brick arch in the hallway, living room or other room:

1. It is important to calculate the proportions of the future arch as accurately as possible, since failure to comply with them leads to uneven distribution of weight. As a result, cracks may appear or collapse may occur.
2. It is important to remove the template in time. If it is left, the wood swells and installation does not occur correctly. To avoid this, the template is covered with construction film before installation.
3. You cannot use metal to make a template: the lack of necessary elasticity prevents correct installation and uniform load distribution, which can result in cracks.

DIY arch made of wood

Wooden arches look great in any part of the house, especially in the hallway, immediately declaring the solidity, good taste and high status of their owners. The process of making a wooden arch is not easy, it requires attention and some skills. Before installing such an arch, you need to decide what shape it will have by looking at the corresponding photos and videos.

So, for a hallway, kitchen or living room in a high-tech or minimalist style, wooden “portal” arches are perfect. It is easier to make than other forms, but with all its simplicity it makes the room sophisticated and elegant. Installing a simple square or rectangular arch does not require any special skills: you can connect its straight parts using staples or special glue.

Features of installation of wooden arches

Rounded wooden arches are created by joining individual small pieces together with glue or metal staples.

The process of installing a wooden arch begins with careful preparation of the place for it: the wall must be cleaned, leveled, then the opening must be given the desired shape depending on the chosen shape of the arch. The size of the doorway should ultimately match the parameters of the arch.

Installation of wooden arches requires great care - both the structure itself and the part of the wall into which it is installed need to be treated with care. The arch should fit into the opening exactly, without voids along the edge, without peeking out or hiding behind the edges of the wall.

At the end of installation finishing finished arch. It is usually coated with paint or varnish to preserve its original appearance and disguise irregularities, chips and dents.

How to make a semi-arch or arch from fiberboard or chipboard

Such sheet materials, like fiberboard, chipboard or plywood, they are easy to install, and they cost much less than natural wood. In addition, they are easy to decorate as desired. Chipboard or fiberboard are indispensable if you want to create a custom arch design and save money. In addition, it is easy to install built-in lamps into an arch made of these materials - such an arch, in particular in the hallway, will look very impressive.

How to make an arch in an apartment from plasterboard

The easiest way is to make an arch yourself from drywall. Making an arch from this material does not require special knowledge, and even not very to an experienced master. In this way, it is good to make, for example, an arch leading from the hallway to the kitchen, since wooden arches are more difficult to install and require special care in this area.

Installation of a plasterboard arch - main steps

1. Before you make an arch with your own hands, you need to choose a project for the future arch and draw its life-size template.
2. Installation of metal profile

The best type of profile for this is in the shape of the letter "P". In addition to the guide profile, you need special scissors and a hole punch for working on metal.

First of all, the required profile length is calculated, depending on the size of the selected arch. On the measured and cut piece of profile, cuts are made at a distance of about 1 cm from each other (this will help give it the desired shape). Then, by bending the profile, the arch frame is obtained.

1. Preparing drywall.

It is carefully bent to the shape of the frame. There are several ways to do this - to choose the best one, it is better to watch the corresponding video.

1. Preparing the opening surface

Here you first need to level the wall, then strengthen the metal profile on both sides of the opening. Next, you need to attach the previously curved part of the profile to the straight profile installed in the opening. And then assemble all parts of the arch structure and attach them using self-tapping screws.

1. Finishing the finished arch in the kitchen, hallway, living room or other room of the house

This stage includes processing with a perforated corner, sealing seams and joints of the structure, puttying the arch and grinding its surfaces. Only after this the arch in the hallway or other part of the apartment can be decorated to your liking.

How to make an arch in a doorway? This question interests many owners of apartments and private houses.

It should be noted right away that an arched opening can only look ideal in rooms with high ceilings.

With low ceilings, such a structure visually significantly reduces the opening. Therefore, you should think carefully before deciding to build an arch. If you accept it, then you can find a lot of materials to implement your idea.

Methods for constructing arches

How to make an arch instead of doors? Today there are such ways to create arches:

1. For an arched opening, the wall is hollowed out according to pre-made markings. This method is more suitable for rooms with not very high ceilings.
2. If the ceilings and doorways are of sufficient height, their upper part is sealed with pieces of plasterboard or plywood to give them an arched shape.

When chiseling a wall proceed as follows:

1. You need to remove all decorative finishing including door frame.
2. From the floor itself, a vertical line is marked on both sides of the opening to the height of the future arch. For accurate markings, use a level or plumb line.
3. The width of the marked opening is measured and divided in half. The result is the radius of the arch.
4. The center of the arch is marked on the upper horizontal line. A screw, self-tapping screw or nail is fixed to this point.
5. A strong thread is tied to the screw, the other end is attached to a pencil. The excess thread is wound around the pencil, leaving a length equal to the radius of the arch.
6. A mark is made on the vertical line from the center point downwards at a radius distance.
7. A semicircle of the upper part of the arch is outlined.
8. On the other side of the wall, the marking operations are repeated.

Now you can start chiseling using a hammer drill or other tool. The choice of tool depends on the wall material. It is recommended to drill as much as possible along the intended contour more holes. They will help in the chiselling process. IN wooden wall The opening is cut out with a jigsaw or a hacksaw with a narrow blade. Final stage preparatory work– processing the edges of the resulting opening and decorating it with prepared materials.

With high ceilings, you can make a door arch if you follow this sequence of actions:

1. In an opening made of wooden or metal profiles The frame of the future arch is assembled.
2. Marking is done on drywall or other material from which rectangles need to be cut. Their width is equal to the radius of the arch, their length is equal to the width of the opening. By using large compass or threads with a pencil, mark the upper arcs of the arch and cut them out with a jigsaw.
3. The resulting blanks are attached to the frame with hardened self-tapping screws. Their caps are recessed 0.5-1 mm into the drywall.
4. The end of the opening is sealed. This can be done using fiberboard. This material bends quite well. You can use a strip of plasterboard 8 mm thick. It is rolled several times with a needle roller and sprinkled with water. Punctures are made to a depth of up to half the thickness of the drywall sheet.
5. If there is no needle roller, punctures can be made with an ordinary awl. The distance between them is about 1 cm. They are made only on the side where the part will be bent. After some time (after about 1-1.5 hours), the plaster gets wet and the strip bends quite easily. It is better to bend it on a wooden or plasterboard template. After drying, it becomes hard again.
6. Drywall is puttied and the arch is decorated at your discretion.

Arch configurations

An arch in a house gives the rooms a certain personality. Configurations and forms arched openings there are quite a few. Let's look at some of them:

1. The classic version is suitable for rooms with a height of 3 m. Arch correct form has a bend radius of 45 cm or more. If you add it to the height of the doorway, then total height There simply may not be enough space.
2. The Art Nouveau arch is often erected in standard apartments. Its radius exceeds the width of the doorway, so there are angles between the vertical elements and the arc. They can be made sharp or rounded.
3. Romantic style is an arch option for large openings. There can be a horizontal insert between the rounded corners, or it can be installed at an angle.

The configuration of the arch depends on the desire and aesthetic taste of the owner of the home. An arched opening can be wavy, polygonal, illuminated, with various niches and shelves, with stained glass windows and so on.

Materials for arch equipment

The arched opening can be made from monolithic concrete, plastic, brick, metal, wood, chipboard, fiberboard, plywood, plasterboard sheets and other materials. When using brick, concrete or stone, their weight must be taken into account. Such structures may require a special foundation and reinforcement elements for connection with the walls.

Metal is a material that fits into any style. But not every metal is suitable for these purposes. Option from of stainless steel is very expensive. Galvanized iron in interior spaces doesn't look good. It is quite difficult to make complex figures from metal.

Wood is a beautiful natural material. It requires virtually no additional finishing.

Drywall, wood fiber and particle board. These Construction Materials can be finished with plaster, painted, covered with a layer of decorative or ordinary plaster, paste over with wallpaper, veneer with decorative stone.

Plastic is a material that is easy to process. Plastic structures are not required additional processing and finishing.

To decorate the arches, they also sell ready-made designs from different materials.

1. The appearance of the arch must correspond overall design premises. Each side of the opening can be designed differently.
2. Any work on the construction of arched openings begins with dismantling the door frame.
3. For convenience and to speed up the marking process, it is recommended to use a full-size template. It can be made from cardboard.
4. When constructing curved frame elements from metal profiles, slots are made on them that allow the workpiece to be bent. The slots are made in increments of about 5 cm.
5. For work, a drill or hammer drill, a hammer, iron scissors and a hacksaw are usually used. Sometimes other tools may be needed.
6. The frame is attached 10-12 mm deep into the doorway so that the drywall attached to it is flush with the wall after puttying.
7. The mounted structure is sanded and puttied. You can cover surfaces and corners with fiberglass mesh.
