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.
