Application Information
Instructions for use

For manual mixing, add to the mixing container 12 - 13 litres of water for each 25 Kg bag of Acoustic Plaster or 12-14 litres/25 kg 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 a uniform, lump-free consistency is achieved.
Leave the mixed material to stand for 5 min and briefly remix without addition of water.
Manual mixing is allowed for small batch quantities and mix for approx. 1-2 min or when homogenous mix is achieved.
When required add 1.0 litres of Vetonit Bond 2 to the mixing water and adjust the water requirement accordingly for each 25 kg bag. Follow same mixing procedure as above.Mixed material must be used within 30 minute. Do not add water once the mixed plaster mortar start to stiffen or harden.

Smooth Concrete Surfaces
Add 0.5 litres of Vetonit Bond 2 to the mixing water and adjust the water requirement accordingly for each 25 kg bag. Follow same mixing procedure as above.
Mixed material must be used within 30 minute. Do not add water once the mixed plaster mortar start to stiffen or hardened.

Acoustic Plaster is generally applied in a single coat method. Use directly on block walls & rough surfaces. On smooth surfaces apply first a coat of Vetonit Spatter Dash S or SB.
Apply mixed material using spray machine or trowel technique to cover the area to desired thickness. Lightweight leveling tools are required in conjunction with 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 wet sponge, wipe the surface to a creamy smooth finish. For colors other than white, spray a Finish WR (desired colour) at 2 mm thickness over Vetonit Acoustic Plaster after 7 day cure.

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

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

Surface Preparation

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