Topsealer® WT Spray Gloss (Component A 3 L) is a two-component water-based polyurethane varnish, specially formulated for spray application on microcement and stamped concrete. It offers a glossy finish that enhances colors, provides extreme hardness and advanced chemical resistance, and does not yellow upon exposure to sunlight. Ideal for protecting decorative coatings in indoor and outdoor areas with high aesthetic and functional requirements.

Main features

• Exclusive spray application using a professional spray gun system, which guarantees uniformity and a perfect finish.
• High resistance to abrasion, scratches, and household chemical agents such as bleach or vinegar.
• High hardness, ensuring robust protection without losing water vapor permeability.
• Does not yellow over time under sunlight.
• Transparent and glossy, it enhances the texture and color of the surface without altering them.
• Presentation of 3 L of Component A, suitable for medium-sized projects or specific areas.

Instructions for use

1. Homogenize Component A by stirring and let it rest for 30 minutes before use.
2. Mix in a proportion of 3 L of Component A to 1 L of Component B using mechanical stirring at low speed.
3. Prepare the substrate: it must be clean, dry, and free of dust or grease; in case of repainting, remove deteriorated paint by sanding or stripping.
4. Apply one coat with a spray gun, maintaining a constant distance; allow at least 24 hours of drying before use.
5. If two coats are applied, leave at least 12 hours between them.
6. Maintain an ambient temperature between 15 °C and 30 °C during application; do not apply under adverse temperature or humidity conditions.
7. Allow at least 7 days for full curing to reach all its mechanical and chemical properties.
