Substrate type
Reinforcing layer of thermal insulation system, cement and cement-lime plasters, concrete substrates.

Substrate preparation
The substrate should be dry, clean, stable, sound and properly seasoned (reinforcing layer at least 3 days after embedding mesh in adhesive, plaster – 28 days after application, seasoned concrete.) Remove brittle and loose material of poor bonding strength, patch chipped plaster with ALPOL AZ 130 quick-setting mortar or ALPOL AZ 135 levelling mortar. Treat loose or absorbing substrates with ALPOL AG 700 deep-penetrating primer. Treat the substrate with ALPOL AG 706 plaster primer at least 24 hours before applying the plaster. It is recommended to stain the primer to the colour of plaster.

Instructions for use
Carefully mix the plaster with low-speed mixer before application. Apply with a stainless steel float, remove the excess and level to the grain thickness, and then trowel with a plastic float to achieve a dashed or pitted texture, as required. Continue working on a given surface to avoid differences in plaster texture. The surfaces should be joined, applying “wet-on-wet” technique. It is recommended that plaster of the same batch is applied to cover the entire surface. If the plaster is applied at the colour joint, building corners and under the downpipes, the works should be stopped accordingly.

Tools
Mixer or low-speed electric drill, basket mixer, stainless steel floats, trowels and plastic floats, spraying unit.

Working conditions
Before use, check if the colour is as ordered. Work in ambient temperatures between +8°C and +25°C. The plaster must not be mixed with other plasters, bonds, fillers or stains not included in the staining system. Do not thin with water. Do not use dirty or rusty tools or containers. Avoid working in intense, direct sunlight, strong wind and high air humidity. Protect freshly applied plaster with a mesh. Incorrect conditions at plaster application and drying phases may result in discolouration and tint distortion.

Storage
In original, not damaged, tightly closed containers in temperature between +8°C and +25°C – shelf life 12 months from production date. Protect the product from freezing and overheating.

Notes
The specifications and instructions for use are given for the temperature of (20±2)°C and relative air humidity of (60±5)%. Drying and final set time may alter in different conditions. Wear safety goggles. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. Protect your skin. Use protective clothing and gloves. 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.
