Do you know what the white paint on the outer layer of the soundproof glass wool board is?

This is a soundproof coating, a high-performance viscoelastic polymer. By spraying a layer of soundproof coating on the cement base, it can damp and suppress the vibration and noise of the object, thereby achieving the effect of sound insulation, vibration reduction and noise reduction.

Soundproof coating is also called soundproof damping coating, which is mainly used for floor and wall sound insulation. This coating is formulated with acrylic emulsion, mica powder, polymer damping agent, damping mineral filler, flame retardant, etc. It is an environmentally friendly water-based coating. After film formation, it can be used to improve the impact sound insulation performance of the floor. Soundproof coating has excellent properties and quality such as sound absorption and noise reduction, earthquake resistance and sound insulation, good substrate compatibility, no hollowing and no delamination, thermal insulation, damping and noise reduction, fire resistance and antibacterial.

The use of soundproof coating usually includes spraying and rolling. The specific method depends on the construction requirements and coating characteristics. For example, it can be sprayed with a stone paint spray gun or a double-nozzle spray gun, or rolled with a roller brush. When spraying, keep the muzzle of the gun vertical to the wall to ensure even coverage of the paint; when rolling, pay attention to the uniformity of the thickness of the paint.
