Stone water repellent treatment BKK Eco

for bricksfor masonryfor absorptive walls

BKK Eco is a colourless water repellent coating that can be applied to exterior walls. It prevents water absorption due to wind driven rain, is breathable and lets moisture dry out ensuring the wall’s insulation performs at its highest level. BKK Eco prevents algae growing and helps reduce the risk of salt deposits forming. If water is not absorbed, it can’t freeze and degrade the wall surface. By keeping the wall dry for longer, this in turn 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. Where to use it Diasen BKK Eco can be used on exposed stone, masonry walls and plasters from water absorption due to wind driven rain. It has no visible effect on the wall so is an ideal protective coat for solid stone or masonry walls that are insulated internally with Diathonite Thermal Plaster. It may also be used internally to protect Diathonite plastered walls when the bare plaster is not finished with Argacem HP and Decork (for example when the plastered wall will have timber paneling installed over the top). It may also be applied over Argacem HP where the homeowner does not wish to paint the finish plaster. Please note, natural variations in the consistency of the finish plaster will then be exposed. To attain the most consistent finish it is recommended to paint with a breathable finish such as breathable natural paints.
