Painting crushed stone at home. Self-painting technology for crushed stone. Cost of equipment for painting crushed stone

Colored crushed stone and decorative chips are used in landscape design, in creating favorable microclimate in terrariums and aquariums. The production of colored crushed stone and chips is quite profitable, since the unpainted version - the raw material - is much cheaper than the final version.

Marble crushed stone, granite or marble chips, or gravel or sand.

• private individuals using building stone for landscaping adjacent areas;
• municipal organizations and city landscaping services for the design of lawns and flower beds;
• companies performing specific landscape creation work;
• organizations of funeral services performing arrangement of cemetery plots;
• pet owners who purchase colored crushed stone and chips to provide a natural microclimate for aquariums and terrariums;
• pet store owners to create a spectacular environment.

Manufacturing technology

Crushed stone of a fraction from 10 to 30 mm is suitable as a raw material, and can be used to add color different paint, as well as various binders. The principle of manufacturing products does not involve any complex operations, as a result of which we obtain a product that is quite in demand in modern construction material for creation landscape design- multi-colored stone.

Process video:

1) It is planned to purchase specially selected raw materials, medium-fraction stones, in the range from 10 to 30 mm. When purchasing crushed stone of a specific fraction, there is no need for additional sorting. The material is stored in a bunker, from where it is shipped for painting as needed. Shovels are used for batch loading. Storing crushed stone without cover is not recommended, as the pores of the stone become clogged, and the quality of painting suffers as a result. To apply paint, it is necessary to ensure a dry and clean surface of the material. Based on the volume of transportation, which is most often carried out by KAMAZ, a one-time delivery of cargo equates to a volume of about 14 tons (10 m3).

2) The delivered crushed stone or crumbs are placed in a painting hopper, the function of which can be performed by a concrete mixer. If the standard volume of a concrete mixer is 0.7 cubic meters, and it is not filled to the brim, but slightly above half, then the crushed stone occupies approximately 0.5 cubic meters. Paint is added to the material in one container. To get 2 tons of finished material during a shift, the concrete mixer must work three cycles. Reducing the volume of raw materials loaded into a concrete mixer is impractical: the profitability of production will decrease, since to obtain the same volume finished products required large quantity concrete mixer operating cycles. In practice it looks like this: 0.2 cubes need to be run 6 times to get a result of 2 tons (in in this case a cube of crushed stone/crumbs is 1.41 t).

4) Next, if used, for example, granite chips, then it is sifted through a vibrating sieve. It is ideal to use a sieve with a tray. After dyeing, each pebble should have a uniform color and be clean. If we compare ordinary and painted crushed stone, the difference looks like this: a ton of colored colored crushed stone costs 22-24 thousand rubles, and a ton of unpainted crushed stone costs 1,000 rubles. Of course, the buyer will carefully analyze the quality of the product, so it is unjustified to be careless in drying technology.

5) The finished colored crushed stone or decorative chips are stored using for this purpose the same bunker as for storing raw materials. On storing expensive products without packaging and protective coating there is no question. It is packaged dry and clean.

6) Tara. Traditional packaging is bags designed for loads from 5 to 20 kg. The packaging process is carried out manually and with the involvement auxiliary tool(shovels). Filled bags are healed using a bag sewing mechanism.

Equipment for the production of

The production of multi-colored crushed stone does not require large investments if ready-made raw materials are used.

Equipment includes:

• bunker No. 1 (for raw materials);
• concrete mixer (for painting);
• vibrating sieve (for sifting);
• bunker No. 2 (for finished products);
• device for sewing bags.

Equipment is selected taking into account maximum productivity and lowest cost.

Two bunkers for bulk building materials with a capacity of 10 m3 will cost 300,000 rubles; domestically produced concrete mixer – 200,000 rubles; vibrating sieve – 40,000 rubles; bag sewing device (preferably made in Belgium) – 40,000 rubles.

The above set of equipment for the production of colored crushed stone is designed to produce products in a volume of 10 m3 per shift. Based on the capacity of a concrete mixer, for example, the Prof-BS700 brand, which produces 0.7 m3 of product in a quarter of an hour, and the drying time for each batch, which is about 5 minutes, it will not be possible to obtain more.

Additional equipment and consumables

To paint stone, you need a dye and at least two shovels intended for loading raw materials into a concrete mixer, from it into a vibrating sieve, and then into the finished product bunker. If the cost of a shovel is about 300 rubles, four shovels will cost 1,200 rubles.

Since the paint and binding materials may be different, the prices for them are different. Most likely, you will have to experiment with dyes in your search best option for your business producing colored decorative stones.

Painted crushed stone or crumbs are packed in 20 kg bags. Thus, about 2,000 bags will be required per month, costing 9,000 rubles per month.

The need to paint crushed gravel and crushed stone in bright and Beautiful colors occurs when designing areas around reservoirs, forming original flower beds and embankments and the implementation of other landscape projects. The business of its production is highly profitable; with a small amount of dye for crushed stone (within 1 kg per 100) and little effort, the output is a high-quality and highly decorative material of any the desired shade. The technology is considered simple and accessible to perform at home; the volume of products produced is limited only by the size of the concrete mixer bowl.

For these purposes, compositions that are resistant to moisture, ultraviolet radiation and mechanical abrasion are required, ideally changing shade when dissolved with water or mixed with other dyes. There are no special restrictions; sprayed aerosols, facade and alkyd enamels, cement with dry additives and water-borne PVA mixed with pigment can be used. But optimal results are achieved when purchasing polymer paints based on acrylic resins, silicates and styrenes. Having a light resistance of at least 6-7 units and high adhesion with minimal surfaces, they do not fade, wash out or wear out for several years. Special varnishes help to consolidate the effect, but under normal conditions they are not necessary.

Among the time-tested options are Decoril based on high-strength organic dyes, organosilicate composition OS-12-03, acrylic VD-AK-191 and universal enamel PF-115. All of them have a rich and varied range of colors and adhere well to the edges of crushed stone. When choosing specific brand future operating conditions are taken into account. When planning to fill flowerbeds and fences in nets, high-quality façade enamel is sufficient; to obtain a filler suitable for decorating ponds and aquariums, you need to buy a polymer variety based on acrylics.

The given grades are relevant when processing individual portions of gravel volumetric method– by mixing in a concrete mixer bowl or a clean container. When planning to work with aerosols, it is recommended to purchase car spray cans or similar sprays with high adhesion. To reduce their consumption, future decorative crushed stone should first be sprayed or completely soaked in a container with roughness-reducing compounds. For these purposes, you can buy ordinary building primers for outdoor use.

Dyeing technology

The process includes several simple steps: sorting, cleaning and drying the material → preparing working tools and paintwork materials (most are sold ready-made or easily diluted with water, but some cheap brands and independent mixtures require pre-soaking and thorough stirring) → loading into a bowl or hopper and direct painting → decanting residual liquid (if any), drying and packaging of colored crushed stone. Each of the steps requires control, otherwise the grains will not be covered with a uniform film.

At the preparation stage, the stone is cleaned of large debris and, if necessary, sifted through a screen to obtain the desired faction, washed with water and dried. Maximum decorative effect is achieved by applying polymer paint to a medium grain size of 10 mm. Ignore the need for pre-treatment It is not recommended; if there is large debris, individual particles stick together and look unsightly, and the coating peels off faster. Rough, unwashed varieties may also change to a darker color later.

The easiest way to clean is directly on a sieve or mesh using a hose; water under pressure will wash the crushed stone from all sides and drain without delay. When using polymer paint, the fractions are completely dried. At this stage, the crushed grain is laid out in a uniform layer on a grid or mesh and left outside or in a room with good ventilation until the moisture is completely removed. During preparation, it is recommended to divide the material in advance into separate portions of 2/3 of the volume of the mixer bowl. The proportion of acrylic paintwork materials is calculated based on the proportions specified in the instructions or from the ratio 20/80 or 70/30.

After this, it is enough to pour the fractions into the bowl, fill it with color and start the mixing mode for an average of 40 minutes. The operating principle of the mixer (forced or gravity) does not play a special role, but during processing the equipment is protected from overload and overheating. Some types dry faster - in 15-20 minutes, the exact interval is determined experimentally.

The process is considered complete after full coverage particles into an emulsion and the formation of a strong and durable film on them. There should be no unpainted edges or surfaces left. The entire stage takes no more than 1 hour.

Subject to correct proportions The output is almost dry colored crushed stone. To get rid of residues, the material is unloaded onto a sieve or mesh and held over the pallet for some time. After this, the fractions are left until final drying. outdoors. Using modern species paint and distribution thin layer this process takes a few hours, no more. Completely dry products are poured into boxes or packaged for sale. Store in bulk long time no, it's not possible.

To realize design ideas when decorating an interior garden plot products with unlimited color scheme. Stone finishing makes the landscape expressive, emphasizing its features. The use of painted crushed stone allows you to create unusual and original decoration.

Crushed stone is inorganic bulk material of various grain sizes, obtained from gravel, granite, limestone, as well as waste from the construction and metallurgical industries. Its characteristics depend on the raw materials.

1. The frost resistance indicator, as well as strength characteristics, may be low. Crushed stone with medium or weak parameters is quite suitable for painting.

2. There are several forms of grains obtained by crushing stone:

• regular;
• cuboid;
• improved.

Gravel is formed naturally and has a smooth, rounded surface.

3. The natural range of shades is:

• white-gray;
• beige-pink;
• brown-red.

Other color options are extremely rare in nature.

4. In landscape design, the most popular colors are blue, green, red and other tones. You can get them only by painting the crushed stone yourself in a concrete mixer or by hand. For this, dyes are taken that:

• resistant to precipitation;
• do not interact with soils;
• do not affect plants;
• safe for people.

In most cases, gravel or granite backfill is used for decoration. Limestone or secondary types are used much less frequently due to their technical qualities.

Work technology

With the advent of painted crushed stone, the task of improving the space around the house became easier. Offered by manufacturers ready material It has high cost. Doing the work yourself is much cheaper.

There are 2 methods of painting at home: mechanical and manual. The choice depends on the volume of processing required.

• For production, it is better to take cube-shaped gravel with a fraction of up to 10 mm.
• To ensure uniform coloring, the products are divided into fractions. For sorting, a grid or sieve with a certain mesh size or a “screen” is used.
• Depending on the applied composition, the color coating can be either matte or glossy.
• The main requirement is adhesion. It can be good not only natural stone, but also for crushed stone obtained from recycled materials.
• Paint consumption is small. The proportional ratio for mechanical application is 1 liter per 100 kg of gravel.

Before you start working, the gravel needs to be washed, dried, and slightly heated with a burner. This will improve adhesion and allow you to create the desired shade; in addition, unwashed stone will darken.

Decorative work outdoors in the form of garden finishing, laying out sidewalk paths, flower beds can be decorated using such a popular material as colored crushed stone. It has an almost unlimited range of colors (like the paint itself), so it allows you to perform any design ideas . But in construction stores

such material will cost 2-3 times more than its unpainted counterpart, so the question arises: how to paint crushed stone yourself?

Range of applications Demand of this material due to the fact that with its help you can achieve brighter and stylish design, as well as create entire picture-messages reflecting some idea. Painted crushed stone is used for the following purposes:

• creation of original flower beds and lawns;
• design of areas around artificial reservoirs;
• landscape works;
• filling terrariums and aquariums (fine crushed stone).

Choosing a paint product

In conditions where you plan to conduct small Finishing work, you do not want to purchase large quantity building materials, therefore it is better to make colored crushed stone with your own hands, measuring out as much stone as you need for the task at hand.

The good news for many will be that the production technology is simple, and the consumption is low - only 1 kg of paint is used for 100 kg of crushed stone. This rule applies if you are going to paint in a concrete mixer, but with other methods, the consumption increases.

To accomplish this task, you can use any coloring compounds: alkyd paints, water-dispersed, enamels, sometimes they even use PVA glue mixed with dye. But the most favorable option for this purpose is acrylic paint.

This is due to the fact that you need a substance that is resistant to moisture, and also does not fade in the sun, and can hold color for a long time. This is exactly how the above paint is characterized, but besides this, it is also harmless, both for humans and for nature.

Required equipment

To ensure that the entire staining procedure goes quickly and smoothly, you will need the following equipment:

• concrete mixer;
• machine “rumble” - vibrating sieve;
• grid or sieve for washing or drying;
• pallet;
• container for storing finished material.

Preparing the stone before painting

When buying crushed stone, you get a heterogeneous composition; the size of each stone can vary from 10 to 30 mm. There are also smaller fractions that are more suitable for interior decoration. Therefore, packaging by size is necessary.

This can be done manually on a sieve with the right size cells, or, which is faster and easier, use a “screen” machine. Any of the above technologies provides for the separation of excess litter, too small pebbles, and sand.

But in order for the acrylic paint to adhere well, the crushed stone also needs to be washed. This will ensure better adhesion of the dye to the surface of the stone and will allow you to create exactly the shade that you want, since if the stone is not washed it can darken.

You can wash it directly on the screen, using a hose or water from a bucket. Due to the fact that the machine creates shaking, cleaning will take place from all sides. After this, spread the washed mass in a uniform layer on a wire rack and dry it in the open air.

The process of creating painted crushed stone

There is only one way to paint crushed stone, and it is almost automatic, since your participation in the main process will be minimal. The most effective and time-consuming technology involves the use of a concrete mixer. After you have properly prepared all the components, you can proceed to the painting itself, which consists of several stages:

1. Crushed stone should be placed in the concrete mixer to two-thirds the volume of the machine (if the capacity is 0.7 cubic meters).
2. Pour in paint in a ratio of 30 percent to 70 percent stone.
3. Start the mechanism and wait 40-60 minutes until the stone is completely covered with a colored layer.
4. At the end of the “kneading”, drying follows - lay everything out on the mesh, placing a tray underneath, where the remaining paint will run off.

It is not advisable to store dried, painted crushed stone outdoors; it is better to use closed containers.

For protection from external influences it is possible to use. This will give the material an additional decorative effect.

Another way of coloring

If you don’t have access to a concrete mixer, then it will be more difficult to create painted crushed stone, but it is possible - you will have to pour the stone into a container with paint and mix it yourself, and then dry the crushed stone.

Or just spray on the stone spray paint, however, this method does not give a uniform color and uniform staining on all sides.

Make your own painted crushed stone for finishing park areas or a plot near the house is much cheaper than buying a finished product: for an unpainted product you will pay a thousand rubles, while a colored one costs over 20 thousand. Considering such savings and extremely logical production technology, the idea of ​​​​making crushed stone for decoration with your own hands is rationally determined.

Decorative colored crushed stone is a relatively new product on the construction market. However, in Europe it has been used for a long time to decorate flower beds, lawns, and also in landscape design.

Decorative crushed stone is produced by crushing waste generated during the production of facing slabs, as well as waste generated during extraction from solid wood rocks blocks and architectural and construction products.

Advantages of decorative crushed stone

1. It is an economical building material.
2. Prevents the growth of weeds.
3. Sprinkling flower beds and beds with it retains moisture.
4. Easily removed from the soil.
5. Protects the soil from weathering.
6. Safe.
7. Has a long service life.
8. Eco-friendly.
9. Has a wide range of colors.

Scope of application of decorative crushed stone

• Framing monuments.
• Landscape design.
• Aquarium design.
• Creating banks and bottoms of streams and ponds.
• Decoration of houses.
• Creation of inscriptions on lawns and ground.
• Design of garden paths, etc.

Manufacturing technology of decorative crushed stone

The production of this building material should be carried out exclusively using high-quality components - this will provide it with rich and bright colors, and long term storage So, decorative crushed granite stone is taken as the basis for production.

How to make decorative crushed stone

Process of creation decorative crushed stone practically no different from the production process of his colleague - construction crushed stone, except that after the main operations, the first one is painted.

Thus, in order for the crushed stone to acquire long-lasting color, modern equipment is used.

Before you start painting the material, it is divided into fractions in special devices, from which the appropriate sizes of 4.3-6.4 mm are selected. However, one should not think that this variety is necessarily subject to coloring, since white crushed stone is nothing more than marble chips of a natural color.

The process of creating decorative colored crushed stone includes a number of stages:

1. Initially, the crushed stone itself is purchased.

2. Fine particles and debris are then sorted out to ensure that only suitable and selected material remains. For this they use special device, called "rumble". With its help, crushed stone is sifted automatically, which is pre-loaded there with a shovel.

3. If such equipment is not available to you, you can use a large mesh with small holes. It must be stretched and placed at an angle, after which you need to pour building material there and begin to carefully sift through it. When using this technology, all operations are carried out manually.

4. The next stage involves painting. For this, it is recommended to use crushed stone with a fraction of 10 mm or more. Thus, the previously sifted material is placed in a special device, which can be used as a conventional concrete mixer.

5. Then the color is poured into the equipment. To color the stone, it is advisable to take acrylic paint, with a volume of at least 20-30% of the volume of crushed stone.

7. Upon completion of the work, the crushed stone is moved to the receiving hopper, which is a box with a mesh. The latter should be pulled a few centimeters higher from the bottom metal device. The cells in the grid must correspond to 10 mm. Such equipment will reduce paint consumption, since excess acrylic will flow through it to the bottom of the box, from where it can then be reused.

8. The finished product must be thoroughly dried and left in the open air.

Laying decorative crushed stone

Laying colored decorative crushed stone does not require much skill. It's quite simple:

• Initially prepare the terrain (remove debris, weeds and rhizomes);
• then the soil is insulated using roofing felt, geotextile or polyethylene film. In addition, it is fashionable to fill in the required quadrature concrete screed up to 5 cm thickness;
• then drainage is created in the lowest place of the relief;
• a barrier is installed along the perimeter;
• at the end, crushed stone is lined, which is evenly distributed throughout the entire area.

• if you used roofing felt or plastic film, then under the layer of crushed stone it is necessary to pour sand with a thickness of 3-5 cm. It is first recommended to level it around the perimeter, compact it and water it with water for shrinkage;
• if you are designing a garden plot, then designers recommend using decorative colored crushed stone of a fraction of 4-10 mm;
• can be used as a border wild stone, ordinary sidewalk curbs, as well as special plastic or metal strips.

Thus, modern polymer paints for decorative crushed stone are characterized by increased resistance to external and mechanical influences, which allows you to maintain an attractive appearance for a long time appearance designed landscape. Wherein this building material can withstand heavy loads - you can safely walk and dance on it.
