Breathable water-based and colourless rain-repellent coating. Diasen BKK eco is a colourless water-based siloxane coating, suitable for protecting absorbent walls made of brick, stone, cement, etc. from rainwater infiltration. It does not alter the colour of the masonry, protects against frost, blocks the penetration of humidity, allows the water currently present in the masonry to evaporate and enables deep impregnation even on slightly damp materials.
By keeping the wall dry for longer, BKK eco increases the thermal performance of the wall. Compared to traditional solvent based solutions, BKK eco is a completely water based product, not dangerous for environment and health, both during application and curing.
Applications:
Water-repellent impregnation for mineral-based building materials. Product suitable as a preventive treatment against carbonation of exposed concrete. Designed to provide colourless water repellent protection for historic buildings or those of particular architectural merit. It can be used to impregnate exposed walls and bricks, natural stone or unglazed ceramic.
Advantages:
- Do it yourself – quick and easy to apply.
- Long-lasting water repellence.
- Water vapour permeability.
- High resistance to weathering and UV rays
- Does not alter the colour of the masonry
- Prevents the formation of efflorescence and mould on the masonry
- Having a low molecular weight, BKK eco penetrates and makes deep impregnation possible. Impregnations are invisible, extremely lime stable and permeable to water vapour
- Solvent free product
