Mariseal 400 Aqua

Liquid polyurethane waterproofing top coat. Mariseal 400 Aqua is a water-based, pigmented, wear resistant, semi-rigid, colour- and UV-stable, weather stable, one component, aliphatic, 100% polyurethane coating used as a top-coat for protection over the Mariseal 250 Aqua waterproofing membrane, subject to wear and weathering conditions.

It consists of flexible, water based aliphatic polyurethane resins (dispersion), without the addition of inferior acryl resins and other admixtures. When t applied, it forms a hydrophobic, 100% waterproofing polyurethane coating, that protects the waterproofing membrane efficient and on a long term basis.
