PU Finish - 2K Polyurethane Matt Finishing Coat for Roller Application (Water-Based)

The substrate must be load-bearing, dry, sufficiently tensile and compressive strength, and clean. Dust, oil, grease and release agents must be removed in advance by suitable measures.
Application temperature: 15-30 °C (room and substrate temperature) with a maximum relative humidity of 70 %.

1. For mixing, add the entire contents of PU Finish component B into the container of PU Finish component A and mix thoroughly.
2. Immediately after mixing, apply the mixture evenly to the floor with a roller to achieve a homogeneous surface while maintaining the floor texture.
   To achieve a streak-free result, roll first against the direction of the light and then wet-on-wet in the direction of the light source.
   Pro tip: For an even, homogeneous finish, we recommend 2 coats. The waiting time between coats is at least 16 hours at 20 °C.
3. Protect the area from moisture, dust and mechanical stress during curing.
   Walkable after approx. 16 hours, fully loadable after approx. 4 days (temperature-dependent).
4. Allow the material to cure for 48 hours after the second coat. Inside the shower and in areas with permanent water contact, allow 7 days to cure before the coating comes into contact with water.

When sealing microcement, Concrete Effect, and other open-pored and textured surfaces, we recommend, especially inside the shower and in areas with permanent water contact, applying our PU Finish exclusively with a brush (e.g. 10 cm width) in a crosshatch pattern to fully close all pores. For heavily textured surfaces outside the wet area, a brush should also be used (and not a paint roller). We recommend two coats.
