PU Finish - 2K Matte Water-Based Polyurethane Finish for Roller Application

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. Measure and mix only the amount of Component A and Component B
   needed for one coat. Do not mix the entire contents at once unless using it all
   immediately, as mixed material will harden and cannot be stored.
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.
