What is BKK Eco used for?
It's a deep-penetrating, water-repellent treatment for exterior masonry, concrete, and stucco. It prevents water ingress, efflorescence, and algae growth without altering the appearance.

Is it breathable?
Yes — BKK Eco has a vapour permeability coefficient (μ) of 7, making it highly breathable and ideal for historic or moisture-sensitive buildings.

Does it change the appearance of the wall?
No — BKK Eco is a clear, non-film-forming treatment. It preserves the natural look and texture of the substrate.

Can it be used on painted surfaces?
No — BKK Eco is for bare, absorbent mineral substrates only. Do not apply over paint, render, or coatings.

How is it applied?
By brush, roller, or spray gun. One coat is typically sufficient. Avoid over-application.

Is it safe for the environment?
Yes — BKK Eco is water-based, low-VOC, and BCorp certified. It’s safe for plants, animals, and surrounding ecosystems.
