Mariseal 420 Top Coat

The MARISEAL 420 is a pigmented, wear resistant, semi-rigid, color- and UV-stable, weather-stable, cold applied and cold curing, one component aliphatic polyurethane coating used as a top-coat for protection over exposed waterproofing coatings, subject to high wear conditions.
Cures by reaction with ground and air moisture over a unique moisture triggered chemical reaction.

Advantages

• Simple application (roller or airless spray).
• One component.
• Resistant to constant, heavy abrasion and wear conditions.
• Color stable.
• UV stable
• Gives a glossy and easy-to-clean surface.
• Provides high sun reflectivity, contributing to thermoinsulation.
• Does not show the chalking effect of aromatic polyurethane waterproofing coatings.
• Resistant to water.
• Resistant to frost.
• Maintains its mechanical properties over a temperature span of -40oC to +90oC.
• The waterproofed surface can be walked on (public pedestrian traffic).

Uses

• Waterproofing of Decks and Walkways
• Waterproofing of public Pedestrian Traffic Areas
• Waterproofing of Exposed Car Parking areas
• Waterproofing of surfaces exposed to heavy wear conditions.

Used over the MARISEAL 250 or 260, on surfaces with public pedestrian trafficking (e.g. Stadium tribunes) and on surfaces with light car traffic (e.g. Exposed car parking areas)
