It is essential to avoid applying our waxes or Venetian soap to the coating, because the 2-C sealer does not adhere well to it. Prime the dry and dust-free surface with two coats of 2-C Polyurethane Sealer glossy and seal it twice with the 2-C Polyurethane Sealer matt. The sealer is applied crosswise to minimise roller marks. A short-pile roller with microfibres or a foam roller for glazing work is best suited to obtain a beautiful surface. The material must be applied evenly and the use of a paint grid or paint tray is recommended. Applying the sealers twice will give the desired protection. Drying time between first and second coat is minimum 4 and maximum 24 hours. Draw a silicone joint at the connections. Attention: Use natural stone silicone! Dust-dry after approx. 3 hours.
