Polyurethane 2-component sealant

2-C PUR sealer matt

Matt sealer for mineral coatings such as Stucco Extra, Stucco Veneziano, Marmorino and all other marble plasters from our range. Ideally suited for use on floors and on kitchen mirrors, i.e. the back wall behind the worktop, to ensure long-lasting protection. Hot oil and other splashes can be wiped off easily thanks to this sealant. Water beads off, grease stains and the like can be removed with commercially available cleaners.

Processing:

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.
