Instructions for use

For manual mixing, add to the mixing container 10-12 litres of water for each 25 Kg bag of Plaster Gypsum Perlite. 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 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 harden.

Let the plaster set for about 30 min., using wet sponge, wipe the surface to a creamy smooth finish.
