Product Description

Acoustic Plaster is composed of a retarded gypsum, perlite & selected aggregates, and special additives. It is supplied as a dry powder in pre-weighed bags ready to use on-site, which requires only the addition of clean water to produce a cohesive mix. Acoustic Plaster is a high-quality product and provides sound and thermal insulation properties.

Advantages
  • Factory-controlled pre-blend ensures consistently high quality.
  • Requires only the addition of water on-site at the time of usage.
  • A plastering machine can apply it with a suitable Rubber pump.
  • Single coat application with improved workability.
  • Easy application with uniform workflow enables high productivity & superior finishing.
  • Strong adhesion on a variety of substrates.
  • Acoustical properties.
  • Lightweight plaster (half the normal sand/cement plaster).
  • Significantly more resistant to heat transmission than normal sand/cement plaster.
COMPLIANCE STANDARD
  • ASTM C472
  • BS: EN 13279

Instructions for use

Mixing

For manual mixing, add to the mixing container 12-13 liters of water for each 25kg bag of Acoustic Plaster, or 12-14 liters/25kg bag for hopper gun machine application. Add the powder to the water and mix with a mechanical plaster mixer or low-speed electric drill fitted with a suitable paddle for 3-4 minutes until achieving a uniform, lump-free consistency.

Leave the mixed material to stand for 5 min, and briefly remix without adding water.

Blend Acoustic Plaster manually for small quantities and maintain the correct amount of powder to water. Mix for approximately 1-2 minutes until achieving a homogeneous mix.

When required, add 1.0 liters of Vetonit Bond 2 to the mixing water and adjust the water requirement accordingly for each 25kg bag. Follow the same mixing procedure as above. Use the mixed material within 30 minutes. Do not add water once the mixed plaster mortar starts to stiffen or harden.

Smooth Concrete Surfaces

Add 0.5 liters of Vetonit Bond 2 to the mixing water and adjust the water requirement accordingly for each 25kg bag. Follow the same mixing procedure as above.

Use the mixed material within 30 minutes. Do not add water once the mixed plaster mortar starts to stiffen or hardened.

Application

Acoustic Plaster is generally applied in a single coat method. Use directly on block walls & rough surfaces. On smooth surfaces, apply the first coat of Vetonit Spatter Dash SB.

Apply the mixed material using a spray machine or trowel technique to cover the area to the desired thickness. Lightweight leveling tools are required in conjunction with a trowel to fill in holes.

When the plaster stiffens lightly, treat the surface to a smooth level to eliminate all traces of protrusions and undulations. Let the plaster set for about 30 min. Using a wet sponge, wipe the surface to a creamy smooth finish. For colors other than white, spray Vetonit Finish WR's desired color at 2mm thickness over after Vetonit Acoustic Plaster cures for 7-days.

For maximum sound insulation results, leave the finishing pattern of Acoustic Plaster very rough.

Curing

Let the Acoustic Plaster fully dry by itself. Do not use water curing.

Surface Preparation

The surface should be sound, clean, free from loose material, grease, laitance, dirt curing compound, etc.

Before Acoustic Plaster application, wet the entire surfaces with clean potable water, and dry before Acoustic Plaster application.
