Having decided to repair, in any case you need to come up with high-quality finish of the dwelling.In the role as a finishing material in most cases it acts as an ordinary plaster.It is easy and cheap, but with proper operation will result simply magnificent.However, even the experienced master from time to time may encounter in their work with certain difficulties.This applies particularly to the walls made of foam block: a solution to plaster the walls of this material has its own characteristics.
First, the surface of such walls should be checked for the presence of a variety of chips and other mechanical defects.After a thorough cleaning of the surface can be carried out priming.Gradually and carefully distributing the composition of the surface of the wall, wait until it dries out, and themselves at this time of the divorce mortar.But do not expect an easy job, because the foam block - the material is very capricious in this regard.And the composition of the solution for plaster walls must be in compliance with all its requirements.
Take, for example, brick.Brick wall absorbs moisture without problems, and does it evenly.As a result, form a strong coupling between the material of the walls and plaster.And what, in this case behavior in the foam block?It absorbs moisture much better than brick, but in no hurry to give it.As a result, neither of which the uniform distribution of the moisture out of the question.That is why the plaster walls with lime mortar in the case of the foam block completely unacceptable!Lime perfectly absorbs moisture, and after drying simply falls off.
If there is no primer mixture can be spray wall grout for plastering.The reliability and efficiency of this method is tested for decades.The material can be applied only after a layer of mortar dries slightly.Thanks so uncomplicated reception can provide excellent adhesion finishing composition of the wall of the foam block.This effect is due to the fact that moisture from the primer or its substitute well distributed over the surface of the wall.It is possible to dilute the solution for plaster walls blends conventional pretreatment of surfaces.
return to a simple primer mixture.Does the use of a primer solution and plaster any difference?There are, and quite substantial.Above all, an acrylic primer is not suitable.The disadvantage is that during its curing it strongly dries the surrounding surface.It is clear that it is capricious foam block is not suitable.
If you put on the foam block acrylic plaster, then it will not last long.Because of the need to save water during the drying surface temperature should not exceed 27 degrees Celsius.Furthermore, such a solution renders the walls is best to dry in a slightly higher humidity by allocating more time.
short, the simplest method using plaster should recognize justified from an economic point of view.In general, that's all the wisdom for improving the walls of the foam block are exhausted.If we approach the matter sensibly, there is nothing complicated about it, and the solution for plaster walls will keep for years.
