As for minuses DSP, it should be noted here its low strength - less durable (M100), the lack of moisture resistance and fragility. The main drawback, of course, is the low ductility ratio compared to other plasters. Also prohibited TsPSom thin layer plastering.

As for the tricks of life, in order,to increase the strength of the mixture can be added to a certain amount of cement solution, which also increases the cost of the plaster. But to reduce the mixture in the price, the solution can be diluted clay.

It will be more expensive as a DSP and a cement plaster. Advantages of working with this plaster will be the possibility of applying even minimal layers that maximizes the smoothness of surfaces.

  4. "He does not like to connect" with metal structures, so please refrain from the use of its data sheet.

cement-based plaster ↑

This kind of mixture is intended for finishinginterior. They stand out for their durability, strength, ductility, crack resistance and an increased level of moisture resistance. The solution is based on cement plaster - it is widely used for decoration of places with high humidity, but also in areas where there is no heating.

The main ingredient is cement mixtures -sandstone. Ready solution with the addition of medium sandstone in its composition, is capable of applying the plaster layer of more than 5 cm, but only if you use it together with reinforcing mesh.
