Polyurethane Sealer PRO – for Wet Areas & Showers

• Polyurethane Sealer PRO protects surfaces that are in constant contact with water – showers, baths and the area around basins. It is an advanced and fairly costly solution, so we use it selectively in specific wet zones rather than across a whole home.
• Most often we pair it with Marmorinus plaster – together they create the finish known as tadelakt.
• Unlike Lakierus, our matte protective sealer, this one leaves a washable surface that is not matte – it has a natural sheen with a satin look.

Please note: we do not recommend using polyurethane sealer over plain Limewash paint. Polyurethane can reactivate the lime, and a thin coat of lime paint is too delicate for it. Marmorinus and Romanus plasters are far stronger and work well with this sealer.

This is not full waterproofing for the wall. It is a thin decorative coating that shields the plaster or paint beneath from direct contact with water. Clean only with mild products – harsh chemicals can damage the polyurethane layer.

The kit contains

• Sealer primer, 0.72 L (one coat, applied with a brush)
• Two-component sealer, 0.75 L (two coats, applied with a special roller)
• Brush for applying the primer
