Water based paint for painting construction projects deal mainly with a roller, and spray or brush. Dried coating is most often in the air, the duration of time before applying the next layer of no more than 2 hours, full time Drying up to 24 hours coverage is formed as a result of water evaporation and coalescence of polymer particles to form a solid phase. Based on acrylic latexes, and dispersions of epoxy and alkyd resins, copolymers, synthesized with the use of small amounts (3-10%), methacrylic acid, acrylamide, vinylpyridine, and other water-based paints are manufactured for industrial use, forming a thermosetting coating Good adhesion to metal. Such water-based paints are applied, for example, by rolling or electrodeposition, and dried at 80-180 C, on the basis of styrene-butadiene latexes are anti-corrosive primer composition, applied hemoosazhdeniem (the methods of applying paint. coverings natural drying with the best properties form the acrylic water-based paints (see Table 2). PVA coating is not enough water-resistant, styrene-butadiene are prone to contamination and discoloration under the influence of solar radiation. On a range of protective and mechanical properties of coatings formed by water-based paints are inferior enamel, water-based paints are used mainly in construction, transportation, industrial and residential applications for protective and decorative and anticorrosive coatings.
Acrylate water-based paints painted facades, the wooden superstructure of ships, etc., polyvinyl acetate and styrene-butadiene – an advantage interiors. Thermosetting water-based paints are also used as anticorrosive primer on metal. Some water-based paints are painted natural and artificial leather, wooden furniture. The share of water-based paints in paint products in industrialized countries is about 30%.

Try to draw on paper all the planned changes in the room. Of course, to call this design the project may be, is not easy, but for the builders, which invite you to work with, such the image will be very useful. The overall objectives of the repair room, just like any other room, it is important to regularize the room in general. To begin with the replacement of windows, radiators, doors and dismantling old furnish the room. To do this, remove the wallpaper, floor covering, remove the layer of paint from the ceiling. Then check the quality of the electrical wiring, if necessary, Stroebe walls and lay new cables. Then conducting rough finishing.
At the present time are very common all kinds of universal water-borne primer based on acrylic materials. Such compositions provide excellent adhesion to painted material, as well as fit application of latex, acrylic and alkyd paints. So they are suitable for priming the surfaces of concrete, plaster, gypsum board, wood, fiberglass and materials. Today, the production of primer compounds, as water-based and alkyd (GF-021 primer), takes into account the type of work surface: brick, concrete or plaster, plasterboard, wood, plaster walls or ceilings. Depending on the conditions operating surfaces, which use the soil and the type of enamel (eg, enamel PF-115), chosen method of finishing. For the initial surface preparation used primer improves the adhesion between the layers of finishing materials – such soils are called primer-primer. The more expensive coat, the more strictly they are distinguished by appointment, the better their quality and they are generally more environmentally friendly.
This information is intended for those who do not want to buy a pig in a poke. You have decided to get rid of the faded paint, loose plaster, escaping Rustam on his ceiling and order quality suspended ceiling. For this, you see advertisements in newspapers and the Internet, companies that sell and install suspended ceilings Mytishchi, and of course, call a few ads, that would find the company that will meet your cost and quality of services offered. But that would make the right choices you need to know this! It often happens that instead of the original stretch ceiling, the buyer slip a fake, which he did not mean to the ceiling is not in writing, where it is made. Won a few tips on how to buy real quality ceiling and not fall into the hands of fraudsters. Obey the following rules. When choosing a company pay an installer attention on how the announcement is made and that it is written in the text should be not only a mobile phone number, but always steady.
