Sealcem WT AC70 5L

Sealcem® WT AC70 is a water-based acrylic varnish designed to protect and enhance stamped concrete and microcement surfaces. Thanks to its excellent resistance to abrasion, moisture, and alkalinity, it prevents yellowing and enhances the color of pavements while preserving their original texture. It is especially recommended as a protective finish for outdoor areas such as sidewalks, driveways, or pedestrian zones, as well as for decorative systems from the Evoluttion and Sttandard ranges.

Main features

• Single-component water-based varnish, no dilution needed.
• High transparency and color enhancement.
• High resistance to efflorescence, alkalinity, and UV rays.
• Excellent adhesion, even on damp surfaces.
• Tolerates hot tire marks without deterioration.
• Improves curing and extends the lifespan of the substrate.

How to use

1. Wait a minimum of 72 hours after the substrate execution before applying.
2. Completely clean the surface, removing dust, debris, and moisture.
3. Apply the product with a low-pressure spray gun (30-40 cm) in thin, uniform coats.
4. Allow to dry to the touch for 1 to 2 hours before handling the surface.
5. If a second coat is required, apply after 2 to 4 hours of drying.
6. Final drying is achieved between 24 and 48 hours, at which point maximum protection is obtained.

Yield

Approximately between 8 and 10 m²/L, depending on the absorption of the substrate and the application method.
