AG S17

Substrate type
Gypsum boards.

Substrate preparation
The substrate should be firm, and the boards should be permanently fixed to the supporting structure or substrate, observing the gypsum board fixing rules. Square edges should be chamfered with a knife or a plane and treated with ALPOL AG 700 and ALPOL AG 704 primer for absorbing subtrates, to additionally reduce absorption, if necessary. In areas particularly exposed to cracking, e.g.: attic timber structure, use reinforcing tape. 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. Carefully fill joints with ready gypsum putty, using a stainless steel float or a putty knife. Use prepared mix within 1 hour from mixing with water. Throw away unused, hardened gypsum. After drying, sand all irregularities with sand paper or a grinding mesh. Then, apply ALPOL AG S24 gypsum finish coat to achieve smooth finish of the joint.

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

Working conditions
Work in ambient temperatures between +5°C and +30°C. Do not add any other agents. Use clean containers and tools for each mixing. Protect freshly applied gypsum from moisture.

Storage
Store in original, unopened packages in dry place – shelf life 9 months from production date. Protect from moisture during transport and storage.

Notes
The specifications and instructions for use are given for the temperature of (20±2)°C and relative air humidity of (65±5)%. The workability may alter in different conditions. Appropriate eye, respiratory system and skin protection measures should be used. Becomes alkaline after mixing with water. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. Keep away from children. Clean fresh stains with water. The manufacturer accepts no responsibility for damage caused by unskilful or inappropriate use of the product.
