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 about how to plaster foam blocks correctly.
Before starting work, it is necessary to check the surface for pits 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, meanwhile dilute the dry mixture of plaster as indicated on the package, and you can begin to work. But for those who are unfamiliar with this mechanism, it is better to turn to a specialist who knows how to plaster the walls from the foam block for help. When working with this material should take into account some features, ignorance
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
stucco mixture and the brick wall, providing a reliable grip. With the walls of the foam block, everything is much more complicated. How to plaster foam blocks in this case? The wall absorbs all moisture, and the stucco has the risk of remaining dry and crumbling. To avoid such problems, a primer must be used.
But you can do without it, it is enough to sprinkle the wall with a liquid solution of plaster. This method is the most reliable and more economical in comparison with others. Now, knowing how to properly plaster, you can proceed to the next step. Without waiting for the complete drying of the liquid, you need to apply the plaster on the wall. Thanks to this method, the adhesion of the plaster to the wall increases, since the moisture in contact with the foam block is only 20%. All remaining moisture is distributed evenly over the surface of the wall, as is the case with a brick wall.
Now a little about the primer. How to plaster foam blocks after using a primer, if you choose the second option between the stucco mixture and the primer? Then you should know that it is better to avoid acrylic plaster. Its minus 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. She does not get the wet balance that is necessary for a good grip. As a result, the plaster cracks and crumbles.
Since the plaster dries long enough, it is necessary that the room has good air exchange and an acceptable temperature. Such is the temperature range from +3 to + 30º.
From the foregoing, we can conclude that the only right and less costly solution would be to pre-spray the stucco mortar onto the wall.
Here, in principle, all the features of applying plaster on the walls of foam blocks. Using this knowledge, you can easily answer all the questions regarding how to plaster foam blocks correctly. This will make the surface of the walls more smooth, beautiful and without flaws. 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.
