The first and fairly responsible step in achieving this goal is the choice of paintwork by its appearance. It is for the facade that it is precisely the water-dispersion materials made on an acrylic basis that will perform protective and aesthetic functions.
There are such types of water-dispersion materials:
one. Butadienstirolni.
2. Acrylic.
3. Polyvinyl acetate.
Consider the positive aspects and disadvantages of these materials.
For work with wood, dispersion PVA is excellent, but, unfortunately, the colors are non -resistant, performing them based on them, for this reason they are not used so often and are not competitors for acrylic, the cost of which is a small.

For internal work, Butadienstirol dispersions will be indispensable, which perfectly resist moisture, but their resistance is limited. They are affordable.
Regarding the value of acrylic dispersions, in comparison with previous coatings, they are largely more expensive, but at the same time more universal. More than 70 percent of the colors that are produced in Europe are performed on their basis and are used not only in construction, but also in the shipbuilding and automotive industries.
We highlight the main advantages of acrylic materials. Consider how better they are oil and alkyd compounds:
one. The durability of these coatings in external use is up to 30 years. Alkyd, in turn, for 5 years, and oil-up to 3 years.
2. Safety for the surrounding space, environmental friendliness, as acrylic does not distinguish harmful fumes.
3. Universal easy to maintain coating – paint, based on acrylic dispersion can be easily cleaned of dirt.
four. Not explosive or flammable substance.
5. Ease of use-at room temperature, the material may dry in 30-40 minutes after application.
The second, no less important stage is the definition with which surface is to work. Paint and the surface that should be painted should be suitable for. For example, if you should work with concrete, which is new and unrterweight, the use of water-dispersion acrylic dispersion will be the most optimal solution. These paints should have a level of pH more from the level of pH of concrete.
