PERLITE PLASTER

Perlite plaster is one of variations of decorative materials widely used for both interior and exterior decoration works. It is applied for levelling of surfaces and as a decorative coat for walls and ceilings. This coat protects the room from loud sounds and penetration of cold air; it is resistant to the influence of moisture and is perfectly applied upon any kind of surface.

Advantages offered by the perlite plaster:
• It is a completely natural material;
• Thermal conductivity of the perlite plaster is so low that its 5-cm layer provides thermal protection of the house at the level of a brickwork with the thickness of fifteen centimeters;
• It possesses high fire resistant properties, withdraws influence of the moister and temperature drops;
• Perlite plaster is moldable and suitable for application upon any kinds of surfaces;
• It protects the walls from origination of mycelial fungi and mustiness;
• Porous structure of the perlite plaster provides light weight and decreases the overall material consumption;
• The coat is very strong and protects the house from rodents and insects.

Perlite plaster composition and characteristics
How can one explain the above-mentioned properties of this material? The secret is in particular features of the substances, of which it is composed. The composition of perlite plaster obligatorily includes specially processed volcanic sand – the perlite. It is subjected to the influence of a very high temperature and it is foamed forming up air bubbles. It is just this process that provides lightweight and thermal insulation properties of the perlite plaster.
Except the perlite, the composition of the mixture includes sand and various polymeric additives. The base is usually represented either by gypsum of by Portland cement. The sphere of application of such a mixture is very wide. The perlite gypsum plaster is used more than often for coating of indoor walls. It is lightweight and vapor proof creating a special microclimate indoors. At the same time, the perlite Portland cement plaster is mostly used for outdoor works, because it is more resistant to atmospheric impacts.
