Danger of applying a thick layer of plaster

Plastering walls is the easiest and most reliable way to give comfort to your home. Choosing this method of wall decoration, it is necessary to take into account some factors, observing which, you can eliminate the further occurrence of problems with repairs.

Many people, when carrying out repair work on wall decoration, try to solve as many tasks and problems as possible. The most common mistake in this case is the application of a thick layer of plaster. In this way, many are trying to solve the problem of maintaining heat in the home, but this is fraught with extremely negative consequences.

The maximum layer of plaster coating and conditions for its application

Two main things, on which the thickness of the plaster depends, is the surface to be treated and the composition of the material used. With a surface that will be plastered, things are a little simpler. The main task here is the correct processing with primers. On the quality of the primers used, the further quality of the repair as a whole also depends.

As for the composition of plaster mixtures, here the choice is very diverse. And most importantly, this is the right approach to finishing work. Otherwise, the repair will come out very expensive.

Optimal plaster thickness

Layer thickness depends on:

- From the composition of the plaster mixture;

- From the consistency of the mixture;

- From the conditions of the plastering.

There is a common misconception that with an increase in the thickness of the plaster layer, the percentage of heat storage in the room increases. As regards this, numerous studies were conducted, and as a result, the following formula was derived:

Plaster thickness Thermal efficiency
Base layer thickness 10 mm Standard percentage

heat preservation

Layer 2x - 20 mm 30% increase
Further increase in layer 60% reduction in thermal efficiency

From this formula it becomes clear that an increase in wall thickness due to plaster, on the contrary, reduces the percentage of heat storage. Experts recommend adhering to standards in thickness, which are 20 - 30 mm. The effectiveness of plastering will increase significantly if, together with them, various varnishes, impregnations and other similar materials are used.

If it is not possible to do without increasing the layer of plaster, it is recommended to use reinforcement of the treated surface with special beacons.
