Component A Topsealer WT Dragon Supermatt 3L

Topsealer WT Dragon Supermate is component A of a latest-generation two-component water-based polyurethane varnish, formulated to protect surfaces coated with microcement, wood, concrete, parquet, or other decorative substrates. Its super matte finish provides effective protection without altering the natural appearance of the substrate, offering an ultra-matte anti-reflective effect.

This varnish stands out for its high chemical and mechanical resistance, excellent adhesion, and durability in demanding conditions, both indoors and outdoors. It does not yellow over time and offers great stability against ultraviolet radiation.

Main Characteristics

1. Super matte finish (3–6 GU at 60°): visual effect without shine, natural, and elegant.
2. High resistance: excellent performance against wear, scratching, and household chemicals.
3. Applicable indoors and outdoors, with no risk of yellowing.
4. Versatility: compatible with microcement, wood, parquet, concrete, and other porous substrates.

Instructions for Use

1. Preparation: Shake Component A well before use.
2. Mixing: Combine with Component B in a 3:1 ratio by weight. Mix slowly until a homogeneous mixture is obtained and let it rest for 30 minutes.
3. Application: Apply in two thin coats with a roller, brush, or spray gun.
4. Drying between coats: Allow 14 to 24 hours between applications depending on environmental conditions.
5. Curing: Avoid contact with water or intensive use during the first 7 days after the last application.

Yield

Between 5 and 8 m²/L, for the complete system applied in two coats, depending on the substrate and application conditions.
