AG S20

Substrate type
Walls and ceilings made of gypsum, ceramic, silicate, concrete as well as cellular concrete components. Gypsum, cement, cement-lime and lime plasters as well as gypsum boards.

Substrate preparation
Substrate should be seasoned, dry, clean, stable and sound. Remove remains of paint and other contamination. Open scratches and cracks. Significantly chipped areas should be patched with ALPOL AZ 135 levelling mortar. Treat the loose substrate with ALPOL AG 700 deep penetrating primer and primer for absorbing substrates to additionally reduce absorption, if necessary. Protect all steel components (frames, conduits, barriers etc.) from direct contact with gypsum, due to its corrosive action.

Instructions for use
Stir the bag contents manually or mechanically with specified amount of clean and cold water to bring the mixture to homogenous and required consistency. Always pour dry mix into the water. Allow 5 minutes and stir the prepared mix again. Spread the gypsum putty on prepared substrate using a stainless steel float to achieve desired finish. Use reinforcing tape for pointing gypsum board joints. After drying, sand all irregularities with sand paper or a grinding mesh. Use prepared mix within 1 hour from mixing with water. Unused hardening mix cannot be mixed with water again. Throw it away.

Tools
Low-speed electric mixer, basket mixer, container for putty, stainless steel float, putty knife, trowel, drywall hand sander with mesh or sandpaper.
