Hydrostop Sealer

Hydrostop Sealer K-773 19Lt is a premium penetrating sealer designed to safeguard concrete, brick, mortar, and masonry against water intrusion.

Hydrostop Sealer is a clear, water-based liquid that can be applied via spraying or rolling onto both horizontal and vertical surfaces. It preserves the natural appearance and breathability of treated materials while offering exceptional durability, resisting wear, fading, yellowing, cracking, or peeling.

How It Works

Hydrostop Sealer incorporates a unique blend of silane and siloxane compounds that chemically react with silicates beneath the substrate's surface. This reaction forms an impermeable barrier that repels water effectively.
