PU-PRIMER 1K+

PU-PRIMER 1K+

Fast-acting polyurethane primer for porous surfaces

PU-PRIMER 1K+ is a liquid, one-component polyurethane primer. It is designed to improve the adhesion of COATERA coatings and sealants to concrete and other porous substrates.

MAIN FEATURES AND BENEFITS

• Ease of use: It is a one-component system that does not require mixing, making it easy to use.

• Fast setting: Cures quickly even at low temperatures, so sealants can be used the same day.

• Excellent mechanical properties: Characterized by high tensile strength and good elasticity.

• Versatility: Can be used as an economical solution for sealing and protecting interior concrete surfaces.

AREAS OF USE

• Priming of concrete, cement substrates and lightweight concrete.

• Preparation of bricks, other mineral surfaces and wooden substrates.

• Sealing and protection of interior concrete surfaces.

TECHNICAL CHARACTERISTICS

• Consumption for concrete: 150–300 g/m².

• Consumption for sealing interior surfaces: 200 g/m².

• Interval before recoating: From 90 minutes to 24 hours.

• Tensile strength at break: 18–20 N/mm².

• Elongation: 120-180%.

• Viscosity: 30–100 mPas.

• Comparative weight: 0.98–1.02.

INSTRUCTIONS FOR USE

Surface preparation: The surface must be solid, clean, free from dust, oil and other contaminants. Do not use if the substrate humidity exceeds 5% or the temperature is below +5 °C (also if the surface is icy).

Coating:

1. Preparation: Do not pour the primer directly from the original container. Pour only the amount that will be used within 30 minutes and close the original container tightly.

2. Method: Apply a thin layer in one direction using a clean brush or roller to create an even film.

3. Important: Do not touch wet primer as this may impair adhesion. Do not apply over another coat of primer that has already dried.
