Types and top 8 manufacturers of facade paints for exterior concreting
Facade walls are a specific surface that is constantly exposed to ultraviolet radiation, humidity and temperature changes. Therefore, the main requirement for finishing materials is high strength. For exterior work on concrete, facade paints are used on an epoxy, polymer, rubber basis. The quality and durability of the coating depends on the properties of the composition and the correct preparation of the substrate.
Requirements for the coloring composition for exterior work
To work on concrete, the following paint is required:
- increased strength;
- resistant to mechanical damage;
- prevent corrosion;
- withstand gusts of wind;
- frost resistant;
- with high adhesion;
- raincoat;
- vapor permeable;
- antibacterial;
- does not fade under ultraviolet light.
Most facade cladding is designed for a temperature range of -40 to +40 degrees.
Suitable formulation varieties
For painting concrete facades, finishing materials are used, the composition of which more or less meets the requirements.
Acrylic
Acrylics are inexpensive and come in a wide variety of colors.
Silicate
Silicate paint is not resistant to changes in heat and cold.
water-based
The water-based coating wears off quickly due to mechanical stress and household chemicals.
Oil
When applied to untreated concrete, oil paint penetrates the top coat, trapping condensation and promoting cracks in walls.
Polymer based
Polymer paints are divided into one-component and two-component solvent-based paints.
The coating hardens in two days, but is not yet ready for full use.
Lime
The limestone will have to be refurbished soon.
Latex
The concrete wall is cleaned, sanded and primed with deep penetration. The latex paint is applied in several thin layers.
How to find the right mix
When choosing a coating, its consumption is taken into account:
| Kind of paint | Consumption in grams per square meter |
| Acrylic | 130-200 |
| Polymer | 150-200 |
| Oil | 150 |
| Silicate | 100-400 |
| Rubber | 100-300 |
| water-based | 110-130 |
Also, when choosing a composition for a concrete facade, special attention is paid to the following qualities:
- antistatic - the antistatic coating does not attract dust, so it does not require frequent washing;
- type of solvent - water-soluble paints are applied only at positive temperatures, and solvent-based paints - at frost and heat;
- texture - a smooth coating better protects the walls, and the texture looks original;
- color - color is added to white compositions, dark and light shades reflect light in different ways. Therefore, for facades located in a well-lit place, it is better to choose light colors.
For exterior walls, matt paints are more suitable, which are more vapor permeable than glossy paints.
It is important that the cover protects against rain but allows condensation to evaporate. The paint should not fade, crack in the sun and contain flammable substances.
Main Manufacturers
Among domestic and foreign finishing materials for concrete facades, eight brands stand out for their quality and durability.
Dulux Bindo Facade BW
The composition is suitable for stone, brick, is resistant to any climate and serves for 10 years.
Colorex betopaint
The water-based acrylic paint from the Swedish manufacturer is very weather-resistant and suitable for facades made of concrete, brick, plaster and plaster surfaces. Due to its high moisture resistance, it is used to protect walls from moisture in basements.
One-component paint is diluted with water, after hardening it forms a matte finish. A high degree of adhesion and resistance is achieved in combination with the Betoprime primer.
Two types of white base are designed for coloring in dark and light tones.
Sherlastic elastomer
The American product stands out among acrylics due to its high elastic properties. The coating is intended for weather protection of monolithic, prefabricated and mixed concrete facades, as well as plaster.
The coating is durable and weather resistant 21 days after application.
"Tex Profi Facade"
The composition is intended for mineral substrates, applied in 1-2 layers. The coating is presented in two versions - normal and frost-resistant. "Profi" is a decorative water-acrylic paint, which comes in the form of a white, colorless base for coloring. The surface after curing is matte.
The Tex company has been operating in the market of economy-class paints and varnishes for 25 years and is part of the Tikkurila group.
Euro 3 Matte
An acrylic copolymer is part of the water-dispersion paint from the Finnish factory Tikkurila. The coating bonds firmly to concrete, wood and brick.
The composition forms a matte finish. The white base is tinted.
good master
Universal elastic rubber paint suitable for exterior and interior work on concrete, metal, brick, drywall, wood and chipboard.
When working on the concrete, no defects were found. In the bathroom, durable paint replaces the tiles on the walls.
"NOVBYTHIM"
The coating is suitable for painting warehouses and garages.
"Polybetol-Ultra"
The composition can be applied to the surface without a primer, but for better adhesion it is recommended to use it in combination with the Polybetol-Primer primer.
The stages of coloring
When painting unprepared walls, paint consumption increases and its service life decreases. A high-quality and durable coating requires preliminary surface treatment.
Epoxy, polyurethane and rubber paints, when cured, form a hard and durable coating. These compounds are considered the most resistant to abrasion.
Surface preparation
At the initial stage, the walls are cleaned of dirt and dusted with special impregnations. The substances penetrate the top layer of concrete, preserve its structure and prevent the accumulation of dust and moisture.
Padding
For better adhesion of materials, a primer with antibacterial effect of deep penetration is applied. Dark primer is chosen for light paintwork, clear for dark shades. White primer is suitable for pastel colors.
Paint application
To make the coating lay flat, the first coat is applied with a paint roller. A spray gun is used to apply subsequent coats. Hard-to-reach corners and joints are painted with a brush.
Final works
Facade paint is not intended for additional coating. The walls are left to dry completely.
Additional tips and tricks
Features of the design of concrete facades:
- water-dispersion compositions are diluted only with water;
- painting a clean porous concrete wall without putty increases paint consumption by up to five times;
- after applying the primer, you need to monitor the paint consumption; if applied in two or more coats, twice as much coverage will be required;
- a new coat of paint is applied after the complete drying of the previous one;
- before applying the third layer, it is better to wait a day for the paint to dry well inside;
- to repaint a concrete wall, a concrete contact is pre-applied to the old coating.
The main tasks of facade painting are to decorate the house and protect it from the ravages of weather. Properly selected and applied finish extends the life of concrete structures.
