Rubber paint for concrete for outdoor use is made using special additives to achieve unique properties when processing various surfaces with this material. The basis of the material is a mixture of acrylic and water. Due to its water base, the paint is non-toxic, odorless, suitable for treating any surface, and can be used in any room.
When dried, this material acquires the structure of a soft film, which is why it began to be associated with rubber. In addition to increased moisture-resistant qualities, the coating is able to stretch, while maintaining its integrity.
The use of this unique paint on concrete allows the base to be treated without harming others, both during painting and in subsequent years of operation. The multi-layer application of the material provides reliable protection for such complex objects as pools, foundations and floors in the garage.
Processing concrete surfaces with these compounds not only significantly extends the life of the foundations, but also gives the structure a more attractive appearance. Modern industry produces many colors, and therefore to choose the right tone is not difficult.
Non-toxic material can be used not only on the street, but also for the treatment of concrete and other surfaces indoors.
Composition and characteristics
The structure of the paint is a viscous, thick fluid such as mastic. The following substances are used for the manufacture of this material:
- up to 5% water is used as a solvent;
- to gain strength, acrylic latex is added to the composition;
- to obtain a strong surface film, use coalescent;
- antifreeze is added to acquire frost resistance;
- protection against microorganisms provides a special preservative;
- To obtain a certain color, various pigments are used.
The ingredients used make it possible to obtain the following characteristics:
- the paint has excellent adhesion and can be easily applied to any surface - this material can be painted: concrete, metal surfaces, asphalt, slate, wood, plastic;
- the painted surface does not change its characteristics at negative temperatures up to -50 ° C and positive up to + 60 ° C;
- the surface film allows fumes to escape, which is necessary to protect wood structures;
- Properly executed coating dries within two hours;
- apply the considered compounds are recommended using conventional painting tools;
- Due to the structure resembling rubber, machined structures do not allow sliding;
- the rubber coating retains its qualities for 10 years, without losing a high degree of wear resistance;
- the absence of toxic substances in this material makes it completely safe;
- the film on the painted surface can be stretched 4 times, which allows you to maintain protection of the base even with sudden changes in temperature and other deformations.
Application area
The considered paints, due to their high elasticity and moisture resistance, are used for processing various structures in the implementation of construction, finishing and repair work:
- for facing asbestos-cement and metal roofs, which allows you to close small cracks in the roof and give these buildings a beautiful look;
- for waterproofing foundations, hydraulic structures;
- in order to ensure corrosion protection of metal elements of cars;
- for marking the roadway;
- this material covers the floor surface of sports facilities and playgrounds for children;
- rubber coating allows to increase the service life of street fences made of different materials;
- processing of the floor covering of outdoor structures (arbors, terraces), processing of the floor on balconies and loggias;
- This material is recommended for processing any surfaces both indoors and outdoors, however, it is undesirable to use this material when processing furniture.
How to calculate the expense
In order to calculate how much material is needed to coat concrete with rubber paint, the area to be coated should be calculated. The standard consumption is set in the range from 200 to 250 grams per sq.m. concrete base. Preliminary surface treatment with special primers will help to reduce consumption, which is especially important in the presence of multiple pores in concrete.
The application of rubber paint must be done two to three times. In this case, maximum coating efficiency is achieved.
If the maximum value (250 grams per square meter) will go to the first layer, then subsequent layers can be calculated based on the minimum value of 200 grams per square meter.
In some cases, it is appropriate to conduct a trial painting on a limited area. This method will allow you to more accurately calculate the consumption of paint on a specific surface.
Application Instructions
The following tips will help even an inexperienced builder figure out how to apply rubber paint on concrete. The algorithm of actions is as follows:
- Surface cleaning from contamination. Remove old paint and all fines from the surface. If there are oil stains, they should be disposed of with special solvents. Whitewash is removed without residue.
- After removing dirt and old coatings, it is necessary to wash the surface with water or prepare for this purpose a mixture of sodium phosphate and water.
- Prior to applying rubber-based paint for concrete, all cracks must be puttied and excess surplus concrete must be cut down on the surface.
- The smoothed surface is ground and once again all fine fractions are completely removed.
- Before painting, it is necessary to treat the surface with a primer, and for concrete substrates that are outside, for example, a foundation, this procedure is performed twice.
- After priming, thoroughly dry the surface.
- Now you can apply the first layer of rubberized paint for concrete.
- Subsequent layers are applied only after the previous layer has completely dried, usually it takes up to 3 hours.
Popular manufacturers and prices
When purchasing rubber paint, it is necessary to take into account a number of requirements:
- Appointment of a specific type of paint. Some manufacturers produce special types of this material that are already prepared for processing a certain surface, therefore, to paint the roof, it is recommended to purchase paint with high resistance to temperature jumps, and for concrete - with an increased amount of latex;
- Trademark. Foreign analogues exceed domestic materials at a cost of two to three times, while their quality is almost the same;
- Shelf life and quality certificate. It should be remembered that the use of paint is necessary within six months from the date of issue.
The most popular brands of rubber paint include:
Among foreign manufacturers:
- Tikkurila Novasil. The product of the Finnish company contains silicone and is recommended for the treatment of external surfaces. The cost of a 2.7 liter package is about 2,000 rubles.
Among domestic manufacturers:
- Superdecor VD-AK-103. It is highly resistant to atmospheric precipitation, has excellent adhesion to concrete. The cost of 6 kg of packaging is 1100 rubles.
- Rezolux Universal. Excellent resistance to deformation and alkaline environment. The price of a package of 7 kg is 2,800 rubles.
- Prosperity. Silicone-based paint is used for outdoor restoration work. A 12 kg package costs 2,500 rubles.
