Key benefits for you

• Instant leak-blocking action — its flexible membrane actively seals cracks, gaps and porous areas to keep moisture out at the source.
• Comprehensive surface compatibility — a single product that adheres to a broad range of materials, reducing the need for multiple sealants.
• All-weather performance — designed to resist water, UV exposure and harsh temperatures, preserving surface integrity year-round.
• Freeze-thaw resilience — stays flexible in cold weather to prevent micro-cracking as moisture expands during freezing cycles.
• Rapid dry time — forms a tack-free layer in a matter of hours, speeding up project timelines and enabling quicker return to use.

Why this matters — real-world outcomes

Unseen moisture can undermine foundations, promote mold growth, and degrade decorative finishes. All Surface Waterproof Sealant helps you prevent these issues by creating a durable, continuous seal that keeps water at bay. It’s particularly effective for exterior terraces and basements, poolside areas, and vulnerable joints in guttering systems, delivering long-term protection with a simple, one-step application.

What makes it stand out

• One-seal, many surfaces — eliminates the need for surface-specific products while maintaining strong, lasting adhesion.
• Flexible protection you can trust — engineered to move with the substrate, reducing crack propagation and maintaining a tight seal over time.
• Practical, fast-curing formula — ideal for weekend projects or professionals on a tight schedule who need reliable results without long downtime.

How to use (quick guide)

1. Ensure the surface is clean, dry and free of loose material.
