The development of the construction industry leads to the appearance on the market of various materials that are quite simple and in demand. Colored rubble is one of the new types of building materials that have found wide application both in landscape design and in aquaristics and construction.
We will talk about its advantages, manufacturing technology and options for use today.
Application of painted crushed stone
Colored crushed stone is currently in demand by landscape and construction designers, owners of garden and suburban areas, city improvement services, owners of large aquariums. Crushed stone allows you to get original design options for garden and park paths, flower beds, fountains, the bottom of aquariums, as well as floor mosaic panels in residential buildings and apartments.
In landscape design, this new material is loved for a number of useful properties:
it is decorative:
- allows the soil to breathe and conducts moisture well, preventing its rapid evaporation;
- significantly limits the viability of weeds, hindering their development.
Diy crushed stone staining technology
Currently, three types of crushed stone are most accessible to the inhabitants of our country - granite, marble and lime. At the same time, depending on the geological characteristics of different regions, the cost of the extracted and imported species may differ slightly. Lime crushed stone is characterized by enhanced coating, which complicates its coloring and reduces the quality of the finished product. Granite and marble crushed stone of small fractions are most widely used for painting.
As a rule, crushed stone of a cubic shape with an element size of no more than 10-15 millimeters is optimal for staining.
In the absence of the possibility of acquiring a homogeneous material, it will be necessary to calibrate it with the help of special devices or improvised means.
To perform work on crushed stone painting, you will need:
1. place for unloading raw materials, drying and storing finished products; the optimal is the presence of an electrified land plot with an area of 1-2 acres and a simple shed located on it.
2. Electric concrete mixer purchased or self-made;
3. dye in a ratio of 20 kg. for every ton of rubble;
4. a screen for separating crushed stone into fractions or steel mesh with cells of a suitable size in a wooden frame;
5. tank for water with a volume of 100-200 liters;
6. Several plastic honeycomb boxes for washing raw materials, unloading freshly painted crushed stone.
In the event that the result of the work is necessary for you personally, the organization of production does not require large expenditures of finance and effort. Having prepared everything you need and purchasing a granite crushed stone machine, we proceed to painting it. To do this, using an industrial screen or a mesh device, we separate the stones of the required size, wash the granite in portions, lowering a bucket of raw materials in a plastic box into water and making several reciprocating movements. Then we pour the crushed stone onto a flat base - sheets of old linoleum, metal, wooden flooring, etc. Drying time depends on the season and layer thickness. After 0.5 - 1 hour, pour a couple of buckets of rubble into a concrete mixer, turn it on and add the dye in portions.
As the latter, the most affordable paint is water-based or acrylic. Fill it in small portions of about 0.5 kg. for each download, depending on the desired brightness and color intensity. Coloring occurs within 40-60 minutes with stirring. Further - the extraction of raw materials in a wooden box with a mesh bottom, located above the container to collect the flowing excess dye. Then the distribution of freshly painted crushed stone under the shed for drying and storage of the finished material.
From a technological point of view, it is more difficult to paint preheated crushed stone with nitro paints. This technology requires a gas cylinder and a burner. At the same time, the coloring quality is high, the resulting colored crushed stone does not fade for a long time.
In the case of organizing a business for the production and sale of colored crushed stone, it is necessary to preliminarily work out the technology of the production process in a small batch. Having received the material of sufficiently high quality, we begin to search for future consumers. Finished products can be sold both in large batches and retail through hardware stores or bases. The main thing is to study the demand for this type of product for a specific region and the absence of competition. For packaging small batches, it is convenient to use plastic or paper bags of sufficient strength.
Dear readers, if you have any questions, ask them using the form below. We will be glad to communicate with you;)

Thanks for the idea, an interesting technology for dyeing crushed stone! Is the type of crushed stone fundamental for the subsequent work on it? It seems to me. that the granite crushed stone is best suited, such as that of JSC "LSK". Although now you can find such crushed stone already of a characteristic natural color, so there will be no need to spend time and effort on processing it. Well, exotic colors are of course better done according to your way!
Firstly, you need not to miscalculate with the size of crushed stone, then it is better to take a smooth stone, and small colored pebbles in general will be perfectly painted and look in the end.
You know how much money you will give for small colored pebbles for production volumes !!! If it's purely for yourself, it's still okay, but the price for the consumer is too expensive for the sale
Tell me which paint is best to use and which drying method
Polyurethane paint or varnish will give excellent results
Do you practice wholesale? If possible, price by email
Good afternoon. Could you please leave your phone number for consultation. Thanks in advance.
In the photo it is glossy like glass, in practice it doesn’t get such an effect, even when I painted with just a coller with varnish, the varnish tints slightly and the gloss is not the same as if it was painted with enamel paint. Who knows the answer by the technology of painting itself for gloss?
Good afternoon.
If painted with acrylic paint, how long will it last? Under the condition of outdoor operation in rain / snow, from +30 to -35
Good day!
please tell me what paint to use to get glossy painted crushed stone. Facade acrylic matt paints. Thank you.
A two-component polyurethane compound in RAL colors is best suited. It dries quickly enough to a tack-free state and gives a persistent semi-glossy finish. They paint not only crushed stone, but also quartz sand, which can be useful when creating colored compositions. The coating will not fade for decades and will not peel off the stones. And if you lay out the crushed stone immediately after painting on the place of its laying, then before this drying, the pebbles will stick to each other, creating a sufficiently strong carpet, while leaving gaps for the passage of water into the ground. Of course, it's not worth walking on them - the area of their adhesion to each other is too small due to the texture of the rubble. Although, if you take a fraction of 5-10, then with a fairly thick layer, you can get a colored path. It is according to this principle that coatings are created using the "Kamenshvat" composition produced in Russia.
The usual color of expanded clay is brown, brown-pink is found, inside it has a darker shade, sometimes almost black. This is due to the fact that expanded clay is made from clay, it is it that gives color. Its granules are spherical. In the section, you can see that they have a porous glassy structure.
Expanded clay can be called a perfect building material. It is non-flammable, environmentally friendly, as it is made from clay. It has a wide range of applications. This is a floor screed, noise and heat insulation, the production of expanded clay blocks, from which houses are then built, and lightweight concrete.
In horticulture, expanded clay is used for drainage. It benefits plants by optimizing moisture and air exchange in the soil. If there is an excess of moisture in it, it is absorbed by the granules; if there is a shortage, they give water to the soil. It is also used for warming the soil. However, the only color of expanded clay does not give room for imagination, the decorative properties of expanded clay are not great.
Colored expanded clay.
A way out was found - colored expanded clay was developed, which retains all the wonderful qualities of this material. It is used in the garden and for home plants (more often colored expanded clay is used for flowers as a decoration). The variety of colors allows you to choose the desired shade. It could be your favorite color or some interesting combination to match the interior of the room or garden design. Decorative expanded clay will perform several functions - it will not allow the soil to dry out, decorate a window sill or a flower garden, protect street plants from the cold, maintaining a constant microclimate. You will be saved from weeding by compacting the pellets tightly. Moss and mold will not appear on the surface.
When decorating, it goes well with other materials - stone, marble, wood.
In the production of colored expanded clay, the necessary standards are strictly observed. Coloring pigments are used only those that do not change the acid-base characteristics of the soil and do not harm plants and humans with harmful secretions.
Colored expanded clay for landscape design is an irreplaceable thing. Gardeners and florists can experiment endlessly with this material. It allows you to diversify garden paths, flower beds, beds, making them unusual and attractive. It also perfectly decorates an office or apartment, combining aesthetics with practical benefits for plants. To its positive properties, you can also add the possibility of repeated use and an unlimited shelf life.
If you are planning to cover the path in the garden with rubble or make an embankment in the yard, you have a choice - to use gray nondescript rubble or decorative rubble, painted in all colors of the rainbow. No special costs are needed - everyone can make colored rubble with their own hands.
DIY decorative crushed stone - a practical novelty
Decorative crushed stone has recently appeared on the construction market - the manufacturers of this building material are just beginning to master the technology of its painting on an industrial scale. The technology involves the use of paints that are resistant to external factors, non-toxic and harmless to soil and plants. Obtaining colored rubble contributes to the use of this material in landscape design - these are colored garden paths, and rainbow beds and flower beds, the creation of all kinds of inscriptions on the ground, filling around the walls of houses and cottages, framing monuments and creating a bright bottom and a bank in artificial streams and ponds, design of playgrounds and much more.
In addition to external beauty, this is also practical, and in this aspect of the issue, the Europeans, who were the first to master the color of rubble, certainly know a lot - according to their calculations, the use of such an element in the future significantly reduces the cost of maintaining a beautiful view in parks, around monuments and on flower beds. Indeed, backfilling with colored rubble is an extremely durable way to solve various problems. Crushed stone inhibits the growth of weeds, prevents the soil from weathering, freely passes moisture and contributes to its preservation in the soil, and if necessary, it can be collected and used elsewhere or even used for construction purposes.
You can either purchase ready-made decorative material or paint it yourself. When buying, be sure to ask what paints were used to give the appropriate color - polymer paints can retain their color for several decades. In addition, do not hesitate to look into the bag - the material should be of the same fraction, evenly colored and without traces of premature paint peeling.
Do-it-yourself colored crushed stone - production technology
You can make colored rubble yourself - there is nothing secret and super complicated in the technology itself. To do this, you will need a concrete mixer, a metal mesh, a container for painted rubble, a shovel and, of course, rubble and paints. Granite crushed stone is most often used - it is better painted and, moreover, is quite cheap.
How to make colored rubble with your own hands - a step by step diagram
Step 1: material preparation
Producers of crushed stone for construction work of course do not prepare specially granite crushed stone for painting, therefore, stones of the most different sizes may fall into the general heap. Manufacturers of colored crushed stone use a special device called a "rattle" to separate larger pieces of stone. With its help, by the screening method, bulk materials are sorted into small and large fractions. It is unlikely that you have a "rumble" lying around in the barn, but there will certainly be a metal mesh.
Before painting the crushed stone with your own hands, pull it at an angle of at least 60 ° and pour the crushed stone to the very top with a shovel to ensure a larger sifting scale. Large pieces will roll off the net, while small pieces will fall to the ground under the net. For painting, it is best to use pebbles about 10 mm long - it is most convenient to fill garden paths with such rubble. The smaller one is also useful for decorating flower beds and flower beds, and you can always use up large pieces for construction purposes.
Step 2: painting the rubble
The sorted material must be poured into a concrete mixer. By the way, you can do it yourself if you have an unnecessary metal barrel. The paint of the color we need is poured over the rubble - you can use both polymer and acrylic paints. In order to achieve the best color, the volume of paint should be at least one third of the volume of crushed stone loaded into the concrete mixer. Having started the unit, you can calmly rest for the next 40-60 minutes - this is how much time is needed for uniform staining.
Step 3: drying the stones
While the decorative crushed stone, made by hand, takes on a new color, you can prepare the receiving container, if you have not already done so. The container is a large box with a mesh stretched along its perimeter. If it is a metal net, then it can be pulled at a short distance from the bottom of the box, if you are using a regular net, pull it to the very top of the container. Thanks to this device, excess paint flows freely to the bottom of the box, and the painted material remains on the mesh.
Remove the rubble from the mesh and spread it outdoors to dry with plastic wrap. Remaining paint in the box can be reused to paint a new batch.
How to paint rubble with your own hands - styling and creating patterns
You can also create bright or multi-colored flower beds on your own, without the help of specialists. To do this, you will need a shovel, a wheelbarrow, plastic wrap, curbs, plastic or metal strips, and ready-made decorative gravel.
How to paint rubble with your own hands - a step by step scheme
Step 1: Prepare the place for styling
In the place where the material will be poured, it is necessary to remove about 10 cm of the top layer of soil. Fill the soil in the wheelbarrow - for sure there will be a place in your garden where you can put it later.
Step 2: Expose the curbs
If you decide to make a regular garden path, all you need is to set curbs. Natural stone, or plastic and metal strips can be used in their capacity. The curbs should be firmly on the surface, you can even dig them into the soil slightly.
Colored crushed stone is a natural stone of a fine fraction that has undergone coloring. Painted crushed stone has a smooth surface and does not lose its properties under the influence of high humidity, different temperature conditions, ultraviolet radiation and other negative phenomena.
Description of business ideas for the production of colored rubble
The material also has other names, for example: colored gravel, painted stone, painted pebbles. Decorative crushed stone is sold in bags. The scope of application of the original finishing material is quite large: this is landscape design, and interior decoration, and facade cladding, and even decoration of aquariums.
Our business valuation:
Initial investments - from 100,000 rubles.
Market saturation is medium.
The complexity of starting a business is 5/10.
The production of decorative colored crushed stone can become a profitable business with good development prospects in Russia. And this despite the fact that the initial stage of opening an enterprise does not require large financial investments.
Business can be done even by packing a stone: the price of 1 ton of simple crushed stone is about 2,000 rubles, the price of a bag is 300 rubles. Considering the relatively high cost of painted pebbles, it can be assumed that the enterprise is profitable.
Stone staining technology
The technology for the production of colored crushed stone is not a complicated process, but it requires some knowledge of the properties of dyes and adherence to the algorithm of actions. Coloring of simple marble crushed stone takes place in several stages: painting with special dyes, drying, packing, transportation to the place of sale or storage. One package of decorative stone weighs approximately 20-25 kg.
An aspiring entrepreneur needs to know what paints are used in the process of making an original finishing material. According to experts, the best pigment is acrylic paint for colored crushed stone, but there are other options for giving the desired shade to crushed stone.
The cost of equipment for painting crushed stone
The production of colored rubble is impossible without the right equipment and tools. When using ready-made raw materials, stone coloring is carried out at minimal cost. The expenditure item will only include the purchase of rubble or pebbles, dyes and some devices that can be placed in a small area of no more than 100 m2.
Equipment for the production of colored crushed stone should have an optimal ratio of performance and cost.
The kit includes the following devices:
- container for raw materials (bunker);
- concrete mixer (for painting);
- vibrating sieve (sifting stones);
- storage bin for finished material;
- packing device (or unit for sewing packing).
To load and unload crushed stone, you need to purchase 2-4 shovels, costing about 300 rubles. a piece. The material is packed in 20-25 kg per bag, based on this, 2000 bags should be bought for a month at 4.5 - 5 rubles. a piece.
Tanks for bulk building materials with a volume of 10 cubic meters. meters cost about 150 thousand rubles. a piece. A concrete mixer of the required capacity - from 25 thousand rubles. The cost of a vibrating sieve varies within 90 thousand rubles. When choosing a sewing machine for sewing bags, you should pay attention to Belgian manufacturers. The cost of the device is about 45 thousand rubles.
The set is designed for the production of colored crushed stone in a volume of about 10 cubic meters. meters in 8-10 hours.
If you do not have enough funds, you can do without bunkers for the first time, for example, make homemade boxes. You can also sift the material manually using meshes with a suitable mesh size, postponing the purchase of a vibrating sieve until better times
You can paint colored crushed stone with your own hands using various paints and binders. The composition of dyes may include various components, therefore, the cost of the color scheme will be different.
Judging by the set of equipment and materials, an enterprise for the production of painted crushed stone can be opened with minimal costs not exceeding 100 thousand rubles. At the initial stage, the help of two hired workers without qualifications and certain skills is enough.
Crushed stone painting technology
In order to prevent marriage in the production process, you should familiarize yourself in more detail with how to make colored rubble with your own hands. This requires material with a fraction of 10-30 mm, dyes and binders.
The main stages of production:
- selection of crushed stone of the desired fraction and separation of garbage, while it is important to remember that the material is better painted with a fraction of 10 mm;
- loading raw materials into a concrete mixer;
- addition of dyes: no more than 20% of the total volume of the material;
- mixing paint and crushed stone for an hour, until the material is covered with a uniform film;
- removing the stone from the concrete mixer using a special mesh through which excess coloring matter is removed;
- drying the material;
- finished products.
Financial part
To calculate the profit received from one ton of manufactured products, you need to know the cost of raw materials and the market price of painted crushed stone. Crushed stone costs about 2,000 rubles. per ton. The price of acrylic paint is 200 rubles. for 1 kg. To paint 1 ton of crushed stone, you need to spend about 20 kg of paint, that is, 4000 rubles. The cost of a ton of painted decorative stone is 6,000 rubles. The average market price of finishing material varies from 23,000 rubles. per ton. The maximum deductions are 50% of the net profit. As a result, the entrepreneur will receive about 8,000-10,000 thousand rubles from 1 ton of painted crushed stone. income.
This is a great indicator for.
Sales of products
To determine the sales market, you need to know: in what areas is the painted decorative stone in demand?
Regular customers, including wholesalers, can be:
- private traders buying stone for facades, flower beds, paths, etc.
- utility services;
- landscape design organizations;
- funeral service bureau;
- aquarium salons;
- pet shops, etc.
You can look for clients on your own or using the services of the media, but you must remember about some seasonality of the product: the highest demand is observed from March to September inclusive.
If you are planning to cover the path in the garden with rubble or make an embankment in the yard, you have a choice - to use gray nondescript rubble or decorative rubble, painted in all colors of the rainbow. No special costs are needed - everyone can make colored rubble with their own hands.

If you decide to make a regular garden path, all you need is to set curbs. Natural stone, or plastic and metal strips can be used in their capacity. The curbs should be firmly on the surface, you can even dig them into the soil slightly.
Step 3: prepare the base
After installing the curbs, it is necessary to pour a layer of sand of at least 5 cm. Smooth it around the perimeter and pour water over it for better shrinkage. Let the sand dry a little and proceed to the next stage of preparing the base - lay an insulating material over the sand. Manufacturers offer special synthetic materials with ready-made holes through which water flows. You can use regular plastic wrap, in which you make enough holes in advance to drain water in case of precipitation. Another layer of sand is poured onto the polyethylene, this time already smaller - 2-3 cm.
Step 4: prepare the stencil
If you are planning to make a track or other surface multi-colored, for convenience, prepare in advance the internal borders made of metal or plastic strips. Thanks to them, the crushed stone will not mix with each other, and you, in turn, will be able to form any geometric patterns. You can skip this step if the material is the same color.
Step 5: lining up the colored stones
The last, final step - our decorative crushed stone is evenly poured onto the prepared base. You can level the surface with an ordinary rake. If you are laying gravel on a lawn or in a flower bed, a small layer of 2 cm will be enough; for pedestrian paths, it is advisable to pour at least 4 cm of gravel.
