Features and composition

Soundproofing plaster is one of the finishing options, which, due to its special properties, absorbs up to 50% of noise. This material is used both in residential, office and administrative premises. The ability to absorb sounds is associated with the porous structure and compositional features:

• additional component - polymers;
• For quick drying, preventing cracking and caking, various additives are added in dry form.

Also, soundproofing plaster contains a filler, which gives it a porous structure. As a rule, inexpensive minerals that have undergone pre-treatment (calcination, crushing, swelling) are used for this:

• expanded clay;
• pumicitis;
• vermiculite

Features of applying the composition

Soundproofing putty for walls is truly of high quality and is resistant to sound, humidity and temperature. But the described properties are fully revealed only if applied correctly. Before planning work, there are several important points to consider:

1. The surface must be completely cleaned of the previous coating, especially carefully working on grease stains and other contaminants.
2. All large differences from 10 mm are sealed.
3. If there are cracks, even the smallest ones, they are pre-treated with a cement solution.
4. One of the most important rules is to use a primer that can penetrate to great depths. First, a metal mesh with medium-sized cells (a square with a side of 10 mm) is attached to the wall.

The finishing work itself is carried out according to the general plan. First, prepare a solution in a container, stir it manually or with a mixer and apply it to the wall.It is better to do this in several thin layers, waiting for each one to dry. Then the surface will be perfectly smooth and will last a very long time.
