Masonry components
Cellular concrete blocks, bricks and silicate blocks or other highly absorptive masonry components.

Substrate preparation
Masonry components should be clean and sound, neither frozen nor covered with frost.

Instructions for use
Mix the contents of the bag with specified amount of cold and fresh water and stir manually or mechanically to bring the mortar to homogeneous and required consistency. In low temperatures (up to +5°C) adding warm water is recommended. Masonry works should be started and performed in the temperature above 0°C. If the temperature is expected to drop below 0°C during the masonry works, add denatured alcohol to water in 1:9 ratio (one 25 kg bag: 4.7 l water and 0.5 l denatured alcohol.) Allow 5 minutes and stir the prepared mix throughout again. Bear in mind that the previously laid wall and masonry components to be used should not be frozen, covered with dust, frost or snow. Carefully level the wall base. Apply the ready mortar with a trowel and spread it with notched trowels or with a special dosing device with notched edge. Lay the bricks and press them lightly. Once laid, brick arrangement can be changed within 5 minutes time. Bond the bricks within max. 10 minutes from spreading a thin layer of the mortar on the surface. Apply mortar also to the vertical planes of the bricks if they do not have “interlocks”. Use prepared mix within 1 hour from mixing with water. If the mortar thickens during that time, stir throughout again and do not add water or water with denatured alcohol, as too much amount will prolong setting time and impair resistance to freezing. This will also impair the adhesion and compression strength. Clean and stainless tools are recommended to work with.

Tools
Low-speed electric mixer, basket mixer, mortar dosing device or notched trowel, container for mortar and water.

Working conditions
Work in ambient and surface temperatures between 0°C and +25°C. The setting process is uninterrupted even if air temperature drops down to –10°C. Do not add any other agents to the mortar than denatured alcohol. Protect fresh masonry work from excessive drying, freezing and moisture.

Storage
Store in original, unopened packages in dry place – shelf life 6 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. Becomes alkaline after mixing with water. Irritating to eyes and respiratory system. Appropriate eye, respiratory system and skin protection measures should be used. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. Keep away from children. Use water to remove fresh dirt or ALPOL AI 770 cleaner to remove hardened dirt. The manufacturer accepts no responsibility for damage caused by unskilful or inappropriate use of the product.

General recommendations
Perform masonry works according to building practice, observing health & safety standards and regulations.
