Clear, Eco-Friendly Water-Repellent for Exterior Walls

BKK Eco is a clear, eco-friendly water repellent designed for exterior plaster, stone or masonry walls. It enhances a wall's insulation by preventing water absorption while remaining breathable and allowing natural water evaporation. This innovative formula also inhibits algae growth and salt deposits, reducing the risk of freeze-related surface degradation and improving the wall's thermal performance. Unlike traditional solvent-based repellents, BKK Eco is a water-based solution, making it safe for both environmental and personal health during application and curing.
