In the text such type of finishing material as wearproof paint on concrete for outside works in detail is considered: the existing types of structures, their functionality and properties, characteristics, advantages and shortcomings. It is possible to find information helping to choose in article and to correctly use paints and varnishes for the concrete surfaces operated in street conditions.
Wearproof paint on concrete for outside works and expediency of its use
Concrete – very strong and reliable material allocated with set of useful characteristics. Therefore it is widely used in country construction for construction of houses and upclassing of sites. Concrete structures which are operated in street conditions are exposed to negative impact of weather and weather conditions.
Treat negative factors of influence:
- ultra-violet radiation;
- seasonal freezing and thawing;
- atmospheric precipitation;
- loadings of mechanical property.
Besides, concrete differs in hygroscopicity therefore its structure absorbs large number of the earth and moisture. For this reason material needs the effective and reliable protection capable to lower negative impact of the specified factors. As the majority of finishing materials badly reacts to moisture, for these purposes it is recommended to buy the paint on concrete for outside works having the characteristics corresponding to operational conditions.
Use of such paint will allow to improve decorative properties of concrete, to prolong the term of its service, to hide small roughnesses and defects on surface and also to provide protection against moisture and biological factors of influence.
Criteria for selection of antifreeze paint on concrete for outside works
First of all the qualitative covering has to show resistance to moisture influence. Thanks to it, walls of the room will remain dry. High fire safety and stability before burning in case of sudden ignition – one more important criterion to which it is necessary to pay attention.
Adhesive properties reflect, how well dye is fixed on surface. The this indicator is higher, the paint and varnish layer on the basis will longer remain. If the structure has low adhesion, finishing very quickly will begin to be shelled and exfoliate. The high resistance to influence of direct sunshine is also important. If the covering does not resist UF, the surface will quickly lose color and will burn out.
Helpful advice! If the building is in the region with difficult weather conditions, it is better to choose the most expensive and quality dye. The budgetary option of paint will not be able to provide necessary protection, and alteration of paintings on concrete will be much more expensive, than purchase of good structure.
As concrete structures are operated in the open air, it is necessary to pay attention to such criterion as operating range of temperatures. Sharp change of weather patterns can affect life cycles and exterior of covering therefore it is recommended to use paint for concrete on the street which is capable to sustain heat and frost without loss of the operating ability. Minimum necessary interval is ranging from-40 up to +40 °C.
Such property of dye as vapor permeability, provides access of oxygen to surface thanks to what the probability of accumulation of condensate on walls is excluded. Most of qualitative structures also show resistance to mechanical loadings that increases covering life cycle.
How to choose masonry paint for outside works: main types of dyes
Finishing materials for facades perform two functions at once: decorative and protective. The qualitative covering is capable to keep the properties and characteristics at very low and high temperatures. Some options of finishing are perfectly operated at temperature in the range from-60 to +800ºС.
At masonry paints on concrete for outside works extensive scope of application:
- socle designs;
- concrete walls;
- systems of external and internal pipelines.
Average consumption of dye on concrete surface is equal to 250-650 g/m ². This indicator depends on structure type. Other moments also depend on kind of finishing material. For example, the epoxy group of coverings has the most high resistance to mechanical loadings. Use of silicone, silicate or acrylic paint on concrete for outside works demands thorough training of the basis, it has to be dry and clean.
Paints and varnishes for finishing of front part of buildings raise electric insulation indicators of the basis and also provide protection against influence of water, corrosive alkaline medium and oxidizing processes. The qualitative covering is not inclined to accumulate pollution and can be operated for not less than 7 years.
Helpful advice! If there is need for eco-friendly and fire-resistant covering, specialists recommend to use water emulsion dyes. These structures are diluted with water and do not react to the alkaline environment.
Classification of masonry paints by concrete by way of dissolution
On way of dissolution dyes for facades are divided into two groups:
- Structures for which dilution solvents are used.
Water-soluble dyes are made on the basis of synthetic pitches. Also, at structure there are additional additives, coloring pigments, fillers. Finishing materials which are dissolved by water have high flow capacity. They show resistance to ultra-violet radiation, temperature differences and loadings of mechanical character. The average term of service of such covering makes 10 years.
Structures which are diluted by means of solvents of organic origin can be applied on surface practically at any temperature. Even the increased humidity is not obstacle. As solvent the xylene, solvent or white spirit is usually used. Similar coverings are not deprived also shortcomings. These dyes contain toxic substances and easily ignite. For this reason structures to which dilution solvents are applied are less popular.
Characteristic of popular paints on concrete for water-based outside works
Water-based dyes represent extensive group of finishing materials. The epoxy structures containing hardeners and pitches have the highest operational parameters. Coloring can be carried out practically at any temperature. At the same time finishing material can carry out also role of the grounding structure. Over time epoxy paints do not lose color.
The covering does not react with chemical components and does not pass moisture. Epoxy dyes have also shortcomings. These enamels are presented in the form of two components which before drawing need to be mixed carefully. Repeated coloring is complicated by distinctions in color of masonry paint which turns out after mixing, and that that it is already applied on surface. Besides, finishing allocates hazardous substances.
Structures on acrylic basis are applied on previously prepared surface. For this purpose concrete needs to be purified in the dry way or to wash out and execute drying. It is recommended to put exterior paint on plaster though acrylic structures have excellent adhesive properties. On surface the covering of high strength is formed, it is not afraid of negative impact of the natural phenomena, chemicals and biological threat, for example, of fungi and mold.
Water emulsion dyes practically do not contain toxic substances. They create on surface dense protecting cover in the form of film. Using latex masonry paint as one of subspecies of water emulsion materials, it is possible to receive covering with water-repellent properties.
Helpful advice! In addition to primer, on surfaces which are exposed to influence of the increased humidity it is recommended to use hydrophobic means in addition.
Features of aqueous emulsion masonry paint on brick for outside works
Water emulsion dyes differ in usability, they are in great demand for buyers.
These structures have set of advantages:
- fast drying;
- lack of hazardous substances in structure;
- the dye smell quickly disappears;
- for correction of color of masonry paint special colors which allow to receive practically any shade are used;
- mix is applied very simply;
- after use, painting tools easily give in to the procedure of cleaning.
Use of aqueous emulsion inks has certain restrictions. Coloring can be carried out only at temperature above 0ºС.
As basis water emulsion dyes are divided into the following types of structures:
- Silicone – are applied to production silicone pitches. This type of covering is characterized by high steam permeability. Besides, silicone paints do not contribute to the development of fungus.
- Mineral – as basis cement or lime is used. Material does not differ in high resistance, but is convenient in application.
Characteristic of mineral masonry paint on brick for outside works
Mineral facade color is suitable for finishing of brick surfaces. Thanks to presence at composition of cement, dye such properties as vapor permeability and water resistance are inherent.
One of powerful advantages of this covering is the possibility of recovery of paint and varnish layer. In use any type of finishing material is exposed to negative impact of different factors. As a result the covering loses the novelty, becomes covered by cracks and is shelled. Mineral dye allows to recover attractive exterior of finishing. For these purposes special solution is used. After processing on covering damages are eliminated, initial color is recovered.
Pay attention! It is only possible to start coloring of walls month later after construction. This time enough in order that all processes of lixiviation have ended. Also earlier coloring, but only in complex with special primer is allowed.
Features of acrylic exterior paints on concrete
Acrylic paints equally are suitable both for concrete, and for brick surfaces. For production of these structures acrylic resins are used. As a result of coloring on surface the strong film as covering is formed. It is capable to provide reliable protection against influence of negative environmental factors.
Advantages of dyes on acrylic basis:
- environmental friendliness and safety;
- mix well lays down on the processed surface;
- the excellent covering ability;
- the high density of dye allows to reduce material consumption during coloring;
- the covering passes air, providing ventilation of surface;
- water-repellent properties.
In certain cases the brick badly gives in to coloring. To achieve necessary result the special technology of drawing is used. For this purpose it is necessary to mix acrylic prime coating with dye of the same type on brick. Putting this mix does not cause difficulties, and color remains for 8-10 years.
The average prices of exterior paints from popular producers
The wide range of the paints and varnishes intended for concrete processing is presented at the market. Among producers epoxy Quality Technology Professionalism paints enjoy special popularity. This type of enamel is characterized by wear resistance and wide color palette.
Oil-based Flugger dyes interfere with mold growth and fungus on surface. After drying the covering easily washes.
The English Dulux brand offers the extensive range of finishing materials among which acrylic, organic, aqueous emulsion and impressive masonry paints.
Dyes of Tikkurila are very demanded among consumers. Such popularity is caused by the simple system of drawing and also excellent decorative characteristics of covering.
Helpful advice! Paintings should be planned, considering at the same time weather patterns, for example, humidity and temperature, wind availability.
Use of masonry paints: responses of consumers
The comments of buyers left at forums will help to decide on the choice of dye not only characteristic of structures, but also:
“When there was need for acquisition of masonry paint, I have been a little puzzled with variety of materials. Often heard good reviews about the Finnish compositions of Tikkurila, but the price has nearly frightened off me. Nevertheless has decided to try, having trusted in opinion of people, and has not lost. The quality of paint really corresponds to the price. It has appeared if before coloring to apply the grounding structure on surface, it is possible to cut dye consumption”.
“Tikkurila, of course, is good, but there are also other dyes which on quality it is not worse. For example, Dufa. As the professional I use seven years the Italian and German finishing materials. During this time has managed to try a lot of things. The Polish paint of the Snowball also offers good characteristics and is convenient in work, at the same time the price of material is much lower, than at Tikkurila. All these paints are reliable and durable therefore they can be taken safely in hand”.
Features of the choice of wearproof paint on concrete for floor
Any type of floor covering needs the protective layer providing durability and decorative effect. This requirement concerns not only living rooms, but also rooms of production and warehouse assignment where concrete floor forms the basis. Dyes for concrete surfaces prevent emergence of cracks, increase external attractiveness, durability and firmness on wear.
The protecting cover for floor represents the mix consisting of fillers, coloring pigments, additives of purpose and acrylic resins.
Scope of such dyes extends to the following types of objects:
- warehouse rooms;
- parking lots;
- rooms of production assignment;
- designs of ramps;
- coverings on motor-roads.
By means of the painting structures on concrete it is possible to process all area and also to carry out partial coloring for marking of vertical or horizontal surfaces.
Characteristics of wearproof paints for concrete floor
High rates of resistance to atmospheric factors of influence are inherent in the coverings intended for coloring of concrete floors. They are not afraid of influence of water and the salty environment. Depending on characteristics and the recommendations of the producer, coloring can be single-layer or two-layer. At temperature not less +18ºС drying of structure in one layer happens within 30 min.
Pay attention! Dye for concrete surfaces allowed to cover floors in warehouse where foodstuff is stored. But it is possible to start operation not earlier than in a day after coloring.
For coloring it is recommended to use the roller or brush. Causing structure by means of the sprayer is allowed. Optimum thickness of layer is 6-12 mm. Wearproof paints can be tinted in any shade. At single-layer coloring the consumption of mix makes 250-350 g/m ².
Characteristics of qualitative covering:
|Maximum time of interlaminar drying||2 h|
|Stability before transport and mechanical loads||+|
|Resistance to cleaning agents||+|
|Degree of resilience to atmospheric precipitation||all the year round|
|Working temperature range (minimum admissible indicator)||40ºС|

The data specified in the table are approximate. Universal indicators do not exist, these parameters reflect average technical characteristics which can be considered as optimum for the majority of operational conditions.
Main types of paints on concrete for floor in garage
The enamels intended for processing of concrete surfaces considerably improve utilization properties of floors and walls. Besides, they provide protection against aggressive influence of chemicals.
To destination dyes on concrete are divided into two categories:
- For the places subject to influence of atmospheric precipitation.
- For rooms with special weather conditions, for example, low or very high temperatures.
Wearproof coverings which are provided on sale by the wide range of structures are most often applied:
- oil-based dyes;
- alkyd-urethane mixes.
As a result of use of acrylic paint on concrete for floor on surface the strong covering showing firmness on wear forms. The floor processed by such dye possesses large-scale of protection against the increased humidity. Acrylic structures are universal, application as outside, and in rooms is allowed.
Before coloring by acrylic paint the surface should be cleaned from stratifications of dirt and dust carefully. If the basis is too contaminated, it is necessary to wash it with water and it is good to dry. Acrylic dye is suitable not only for garages, but also for production workshops. Strict restrictions on temperature at which finishing will be carried out, no. Material equally well reacts as to high, and low temperatures.
Pay attention! The optimum expense of structure on acrylic basis is equal to 650 g/m ². If to exceed this indicator, also time of drying of covering will increase.
Concrete floor can be processed also by water emulsion dyes. Water and disperse structures and mixes on latex basis will be suitable for these purposes. Environmental friendliness, fire resistance belongs to their advantages.
Features of wearproof rubber exterior paint
The rubber painting structures on concrete are applied to repair or finishing of the surfaces operated indoors and outside. This type of material well lays down also on plaster (exception are the whitewashed surfaces), wood, plaster, asphalt concrete, brick, ceramic tile. Therefore it is possible to call rubber paint universally applied finishing.
Can be processed by rubber dye:
- entrances under inclination;
- walls and floors;
- separate elements of constructions;
- front part of buildings;
- parking entrances.
It is not recommended to use this material for processing of the floor which is exposed to the serious abrading loadings. This type of covering on furniture and doors is inappropriate.
Features and price of wearproof rubber exterior paints
This type of covering is rather new version finishing and protection of materials.
As a part of dye is:
- acrylate latex;
- coalescent (solvent of organic origin);
- coloring pigments;
- special additives with antifreeze and antifungal properties.
Rubber paints are safe for the environment and for people. And these properties are provided also at coloring stage, and throughout further operation. Also other properties of film covering, such as mechanical firmness are not lost. In the course of coloring the multilayer technology of drawing is used. Rubber finishing perfectly constrains forming of cracks. At the same time the covering well passes air therefore the surface processed by structure “breathes”.
The average time of drying of paint “on has come unstuck” – of 30 min. to 1 h. Full drying of surface will require about 12 h. One liter of dye weighs about 1.1 kg. The protective film is very elastic, degree of distensibility reaches 400%. Thanks to it the covering keeps integrity in use. Working temperature range is from-50 to +60ºС. On average the covering can serve about 10 years.
Helpful advice! During operating time with rubber paint it is necessary to stir slowly periodically structure that finishing laid down thin layer and evenly.
How to calculate consumption of rubber paint on concrete
Predesign of expense will allow to define how many dye will be required for high-quality coloring of object. Thanks to it, the buyer will be able to avoid excess expenses or need in addition to buy in addition material. For this purpose it will be required to know what area of the processed surface. Minimum flow at primary drawing is 250 g/m ².
To learn the necessary volume of dye it is necessary to increase total area by expense. It is desirable to add spare 10% to the received result. The consumption of dye is influenced by quality of the processed surface. The more exactly and more smoothly the basis, the less structure will be required for its coloring. If to apply primer on porous zones, the amount of emptiness will decrease, so, the consumption will be cut and adhesive properties of covering will increase.
It is necessary to consider that repeated putting paint (the second layer) is followed by smaller expense as all emptiness and defects on surface are already filled. It is not recommended to use water for dilution of structure even if dye on water and disperse basis is used. Rubber paints and varnishes are much more economic than some structures. For example, processing of the similar area by means of oil dye will require 2-3 times more structure, than in case with rubber finishing.
Helpful advice! To exclude unpleasant surprises before starting coloring, it is necessary to apply paint in the imperceptible place on the small site of surface. It will allow to make idea of density and density of dye, its shade.
Surface preparation before putting rubber paint on concrete for outside works
Coloring of concrete surface by rubber structure is carried out in two stages. At the first stage the basis is prepared, on the second – putting dye is carried out.
For a start the surface is carefully cleaned from:
- fat spots;
- chalk particles;
- dirt and dust;
- the remains of old covering (if they are present).
If earlier concrete surface has been painted by dyes on alkyd and oil basis, it should be cleaned completely. After that walls are washed out by means of sodium phosphate solution. Then the surface is washed with water and dries. If at walls there are cracks or roughnesses, they need to be covered or to grind slightly. After the performed procedures it is necessary to get rid of construction dust.
Further the grounding structure is caused, it is desirable that it deeply got into basis material. If at object there are metal parts, their coloring needs to be carried out separately, having taken care of drawing corrosion preventing agents. Quite often in construction cellular and porous quality classes are applied. In such cases the surface is painted at least twice.
Technology of coloring of concrete by rubber structure and care of covering
Dye needs to be applied only on dry surface. Before getting to work, the structure should be stirred carefully. If the instruction has provided addition of coloring pigment, material is stirred after its introduction. It is better if not less than three layers are applied on walls.
In work it is recommended to use brush or the roller. The first layer has to be thin and accurate. Repeated causing structure is carried out only after the first coat of paint has dried out. On it about 1 hour leaves. Between the second and third putting dye it is recommended to wait not less than 2-3 hours.
When work is ended, it is necessary to wash at once with clear water all tool until dye has dried up. The covering does not need special leaving, but the first wet cleaning is not recommended to be carried out earlier, than in 7 days after coloring. Use of soap solutions for cleaning of surface and antiseptics is allowed.
You should not save upon dye purchase, most of the qualitative structures on concrete provided on sale have the high price which is justified by high utilization and technical characteristics.
