Substrate type
Clinker brick and tiles, face bricks, natural and artificial stone, mineral decorative plasters, cement and clay roof tiles, concrete, cement joint surfaces and other absorbing masonry and cladding components.

Substrate preparation
The substrate must be clean, sound, dry and free from dirt, mould, fungi, dust and greasy spots. Patch any chipped substrate with appropriate ALPOL mortar. Absorbent or dusty (strongly chalking) mineral substrates should be primed with ALPOL AG 707 silicate-polymer primer for mineral substrates before applying the impregnating agent. When painting newly made surfaces, keep the appropriate drying and seasoning period: three months for concrete, 28 days for cement-lime plasters, 7 days for decorative mineral plasters.
In the event of unfavorable weather conditions, the seasoning period should be extended accordingly. Before starting work, all surfaces that are not impregnated, should be protected.

Instructions for use
Apply a big amount of the product on the surface using a soft paintbrush or a paint roller. Spread the product uniformly from the top and avoid sagging. For larger areas, a low-pressure spray application method is recommended. While spraying, avoid formation of fog. One coat of the impregnating agent is sufficient for most substrates. If necessary, on highly absorbing substrates another coat should be applied before the previous one dries out (the substrate must be still moist). Surfaces stained by the product wash immediately with water. Do not paint impregnated surfaces. Do not use the nano-impregnating agent for waterproofing. Store the nano-impregnating agent in a tightly closed container.

Tools
Paintbrush, paint roller, spraying equipment.

Working conditions
Work in ambient and substrate temperatures between +5°C and +25°C. Do not add any other agents to the preparation. Protect freshly impregnated surface from rain.

Storage
In original, not damaged, tightly closed containers in temperature between +5°C and +25°C – shelf life 12 months from production date. Protect from frost 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 drying time may alter in different climate. 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. 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 works according to the Guidelines to Clinker Nano-system, building practice, observing health & safety standards and regulations.
