Mixing

For mechanical mixing add to the mixing container 7.5- 9.5 litres of water for each 20 Kg bag of Gypsum Joint Compound. 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 10 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 Vetobond AB432 to the mixing water and adjust the water requirement accordingly for each 20 kg bag. Follow the same mixing procedure as above.
Mixed material must be used within 2 hours. Do not add water once the mixed filler mortar start to stiffen or harden.

Application

Gypsum Joint Compound is generally applied in single coat. Spread the Gypsum Joint Compound to the area with wide spatula while filling & pressing firmly into the joints.
Place Joint Tape over the joints with small spatula and spread the excess compound over the joint tape and level it smoothly to the surface while edging out to the sides. Use Saveto Bond 2 before fixing tape for better
adhesion. After hardening, smooth rub the joints to a desired finish.
Gypsum Joint Compound can be applied manually or spray machine as skim coat on top of gypsum board to achieve uniform smooth surface.

Curing

Gypsum Joint Compound sets and cures on its own at room temperature.

Cleaning

All tools should be cleaned immediately after finishing by water. Hardened materials can be cleaned mechanically.
