AG S22 P

Substrate type
Gypsum, cement, cement-lime, lime plasters, gypsum putty, gypsum boards, concrete walls and ceilings.

Substrate preparation
Substrate should be seasoned, clean, dry, stable and sound. Remove remains of paint and other contamination. Widen scratches and cracks and then patch all chipped areas with ALPOL AG S20 gypsum putty. Significantly chipped areas should be patched with ALPOL AZ 135 levelling mortar. Treat the loose substrate with ALPOL AG 700 deep penetrating primer or primer for absorbing substrates. 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 finish coat with a stainless steel float to form a layer between 1 and 2 mm thick, until smooth and regular finish is achieved. Thanks to high quality of the product, another coat may be applied on wet and slightly mat surface in 30 minutes from applying the first one. Before the second coat of the product is applied next day, prime the surface with the primer for absorbing substrates. After drying, sand all irregularities with sand paper or mesh, not allowing to sand the topmost coat. Use prepared mix within 1 hour from mixing with water. Unused hardening gypsum putty cannot be mixed with water again. Throw it away.

Tools
Low-speed electric mixer, hydrodynamic unit, basket mixer, container for putty, stainless steel float, rotary grinder, drywall hand sander with mesh or sandpaper.
