Every person who wants to transform his home is faced with the need for internal and external repairs. One type of finish is plaster. This process is an integral part of any repair. But the question arises of how to properly plaster the foam blocks.
Before starting work, check the surface for holes and irregularities. The next step is to coat the wall with a primer. After the entire wall is covered with a primer, let it dry a little, in the meantime, dilute the dry mix of plaster as indicated on the package, and you can get to work. But for those who are unfamiliar with this mechanism, it is better to seek help from a specialist who knows how to properly plaster foam block walls. When working with this material, you should take into account some features, ignoranceof which will not bring you the desired result. When working with a brick wall, it should be noted that it absorbs twice as much moisture. As a result, moisture is evenly distributed between the plastermixture and a brick wall, providing a reliable hitch. With foam block walls, everything is much more complicated. How to plaster foam blocks in this case? The wall absorbs all the moisture, and the plaster runs the risk of remaining dry and crumbling. A primer must be used to avoid such problems.
But you can do without it, just spray the wall with a liquid plaster solution. This method is the most reliable and more economical than others. Now, knowing how to plaster correctly, you can proceed to the next step. Without waiting for the liquid to dry completely, plaster must be applied to the wall. Thanks to this method, the adhesion of the plaster to the wall increases, since moisture comes into contact with the foam block by only 20%. All remaining moisture is distributed evenly over the surface of the wall, just as in the case of a brick wall.
Now a little about the primer. How to properly plaster foam blocks after using a primer, but if you chose between a liquid mixture of plaster and a primer, is it still the second option? Then you should know that it is better to avoid acrylic plaster. Its disadvantage is that it completely deprives the wall of moisture, as a result of which all of it accumulates on the plaster. And over time, the moisture remaining on the plaster layer evaporates, and the wall becomes dry. It doesn't get that wet balance it needs for a good grip. As a result, the plaster cracks and crumbles.
Because the plaster dries enoughfor a long time, it is necessary that the room has good air exchange and an acceptable temperature. This is the temperature range from +3 to + 30ºС.
From the foregoing, we can conclude that the only true and less costly solution would be to pre-spray a liquid plaster solution on the wall.
That's basically all the features of applying plaster on the walls of foam blocks. Using this knowledge, you can easily answer all questions regarding how to properly plaster foam blocks. This will make the surface of the walls more even, beautiful and flawless. The whole process is not as complicated as it seemed at first glance, but still requires time and effort. The technology for applying plaster is quite standard and does not differ much from the usual one, which is being developed for most building materials.
