Wood (a universal and widely used building material) needs reliable and long-term protection. Conventional coatings, which are mainly used for these purposes, are susceptible to cracking and peeling over time. Relatively recently appeared on the construction market, rubber paint for wood, due to its unique composition, is devoid of these drawbacks. High consumer and technical indicators contribute to its growing popularity, especially in individual construction.
Features of the composition
The term "rubber-based paint for wood" is not entirely correct in relation to this protective coating. Rather, it determines the properties and technical characteristics of this product. In fact, the latter consists of:
- acrylic - the main synthetic polymer binder that forms a protective film on the treated surface;
- latex, which is obtained chemically from artificial rubber (it is he who gives the coating superelastic properties);
- coalescent (for better film formation);
- pigments that give the composition a specific color;
- water as a solvent;
- antifreeze, significantly increasing the frost resistance of the coating;
- special additives and fillers that increase the resistance of the composition to aggressive environments (salts, alkalis and the like);
- antiseptic components that prevent the formation of fungi and mold.
Although almost all ingredients (with the exception of water) are produced through various chemical reactions, the final composition is absolutely environmentally friendly, safe for humans and the environment, and meets all the necessary norms and rules.
Main characteristics
Rubber paints for wood are characterized by:
- water resistant
- high resistance to daily and seasonal temperature differences;
- good adhesion with all building materials made of wood (timber, plywood, boards, fiberboard, chipboard and so on);
- durability (guaranteed service life while maintaining the protective properties of the coating up to 10 years or more);
- high elasticity;
- good vapor permeability (which favorably affects the "breathing" properties of wooden structures);
- high mechanical strength and resistance to abrasion (especially for rubber paints for wood floors );
- increased anti-slip properties (which significantly increases safety when using, for example, stairs);
- resistance to the negative effects of ultraviolet radiation (coating does not change color for a very long time);
- quite economical consumption with a high layer density (although this figure is higher than that of traditional analogues);
- ease of application;
- high drying rate;
- the possibility of applying to a cracked surface (without preliminary putty);
- lack of smell;
- ease of further care using any household detergents.
disadvantages
It is unlikely that you can find at least one product on the modern market of high-tech and innovative building materials that has no drawbacks. So do rubber paint, although there are very few of them:
- the processed surface will be matte (glossy luster cannot be obtained due to the components included in the composition);
- the price of such coatings is higher in comparison with standard (alkyd, acrylic or oil) compositions.
Application area
Rubber paint on wood for outdoor use is successfully used in the construction of a protective coating:
- exterior facades and technological building elements (columns, beams, props and so on) of buildings for various purposes (from a residential country house to a garage or a barn);
- fences and fences;
- plank floors (on open terraces, arbors and balconies);
- elements of stairs (steps, railings, balusters and supporting structures);
- floorings and platforms designed for the convenience of using artificial and natural ponds;
- children's playgrounds and sandboxes;
- hulls and elements of boats, boats and yachts.
Surface preparation
Naturally, the most optimal solution for arranging the protective layer is to apply rubber paint for wood on the street to new or recently built structures. The pores of the building material are not yet clogged with dust, dirt or other foreign impurities. Durability will only benefit from this.
Old surfaces planned for processing must first be thoroughly cleaned with a spatula or scraper, and then with a metal brush or a special nozzle for an electric drill.
Application Method
Almost all manufacturers of rubber paints for wood for external use recommend the following conditions for work, compliance with which will ensure the preservation of the protective properties of the coating during the warranty period:
- The ambient temperature should be between + 5 ° and + 30 ° C (the time of interlayer and final drying indicated on the package is usually for + 20 ° C).
- Humidity - do not exceed 80%.
For application, you can use any painting tools: brushes, rollers, spray guns and other mechanical sprayers.
Before use, the paint must be thoroughly mixed. When using sufficiently large volumes, this procedure must be repeated periodically.
Since rubber paint for wood is usually applied in 2-3 layers, it is necessary to strictly observe the time interval between them, recommended by the manufacturer.
Major manufacturers
Russian manufacturers of various paints and varnishes appreciated the advantages of the new protective coating and quickly mastered the development and production of such products. The most widely represented in the construction market are rubber paints for wood from Super Decor, Master Good, Baltikolor, Rezolux, Dali, LKM USSR, Technoprok.
Naturally, each trademark uses its own individual “recipe” of manufacture and technological features of production. However, everyone strictly complies with the requirements that ensure the safety of people and the environment.
Varieties and prices
The color scheme of currently sold formulations is quite diverse. For some manufacturers, the number of shades of finished products reaches 20. For those who supply products in basic white or light gray, you can either order a specific shade from the catalog, or purchase separate tinting pigments and do independent “design creativity”. It all depends on personal preferences and time, which is sometimes not enough for aesthetic experiments.
By purpose, such coatings can be divided into three main groups:
- universal (for applying to walls and other wooden structures of various buildings);
- increased wear resistance (for floors and wooden flooring) ;
- highly specialized (for wooden waterborne vehicles).
The price of such products depends on the application, composition and manufacturer. So, a can (3 kg) of universal paint VD-AK-103 (base color) from Technoprok will cost 600-700 rubles. Approximately the same price for goods from Dali. But, for example, the same amount of finished color products (for a similar purpose) from Super Decor (flow rate 120-250 ml / m², the period of complete hardening is a week, the technological break between layers is 1.5-3 hours) will cost 850- 950 rubles. Moreover, only imported components are used for its manufacture (according to the manufacturer himself).
Products from German Remmers, Spanish Lepanto or Canadian Liquid Rubber will cost much more.
For wooden boats, boats and yachts
A separate category of such paint is designed to protect the hulls of wooden boats, boats and yachts from both fresh and salt water. The composition of these products add special components for:
- protection against the aggressive effects of salt water;
- prevention of fouling of the bottom by algae and microorganisms, significantly reducing speed and increasing fuel consumption;
- increased adhesion during operation in conditions of increased vibration.
Due to increased operational requirements, the price of such products is higher than their analogues for general construction use. Manufacturers engaged in the production of such highly specialized products: the Norwegian Star Maling, the Russian Baltikolor and LKM USSR and the American Overton's and Totalboat.
Finally
Modern rubber paints for wood, user reviews, which have already put these products into practice, are mostly only positive, fully correspond to the declared characteristics. Essential conditions that must be observed:
- when choosing - take into account the purpose of a particular product (for example, only for vertical surfaces, for the floor or for boats and boats);
- when using - strictly follow all manufacturer's recommendations that are indicated on the package.
