Plaster of foam blocks , as a way to protect and preserve the durability of coatings

methods of manufacturing foam blocks

foam blocks can be made in two ways: injection and sawing .The injection method is very similar to the traditional production of concrete.That is, the solution is poured into a special form, dries and can be removed from there as a final product.Most often, this technology uses iron cluster form.They represent a kind of trays with partitions inside and removable sides.The partitions need to divide into sections form.

This method has several disadvantages.Often produced in different sizes and proportions, withdrawn from the mold blocks.Also there is a great number of rejects due to the presence of "bumps" are formed on top of the blocks.But the main disadvantage is that the plaster for aerated concrete, manufactured by injection method is difficult.This is due to the fact that the surface of the blocks (its sides and angles) during demolding usually damaged.

Sawing method has more advantages.Molded foam in special forms of large, then carried him and stripping section of the relevant size.Thus, the blocks are precise geometry and precise dimensions.Also, the material can be manufactured in the sizes required to the customer.The great advantage is also the fact that the plaster walls of the foam produced by this method is much faster.Reduces labor costs and the cost of funds.

Plaster walls of foam blocks

solution for plaster walls is applied differently depending on the type of foam blocks (their production).For example, the material produced by injection method, it is important to first cleaned and skins to plaster good "mated" with the surface.Material made way cutting, has a slightly rough base and because the plaster is easy to "stick" to the surface.Plus, for those and other units it is important that used a special plaster facade with a high level of adhesion (of which describe below).

For better adhesion can be used and reinforcing mesh.Plaster walls must be in accordance with the general rules.But before that necessarily primed surface.Thickness of the outer layer should be - less than 1 cm, internal - less than 2 centimeters.In the process of work is important to observe the temperature and monitor the level of humidity (temperature from +5 to + 30 ° C).Best of all these steps are shown in the video.Video foam blocks, plaster which is represented in the steps below will help you a lot faster to cope with the work.

What is special plaster for foam blocks?

As already mentioned, for the foam blocks should be selected special plaster, which will have a number of options.What are these options?We list them below.

• have a high level of elasticity.
• good adhesion.
• Water vapor permeability.
• Frost.
• water resistance.

In particular should be checked measure adhesion.Better yet, consult with a specialist, because the quality is not matched material can lead to several problems in the future (cracks, "swelling", flaking coatings and others).
