+30 22620 32918-9 Website

Application

Top coat for use on:

Waterproofing of roofs;
Waterproofing of balconies, terraces and verandas.
Protection of polyurethane foam insulation;
Compatible with decorative floor flakes;
Compatible with silica sand.

Can be used over MARISEAL® 250, 250 FLASH, 260 etc. on surfaces with light pedestrian traffic (e.g. roofs/ terraces/ balconies etc.) that require a glossy, colour-stable and non-chalking finish.

Description

Pigmented, colour and UV stable, highly-permanent elastic polyurethane coating, used as a top coat for protection over exposed polyurethane waterproofing membranes.

Features and benefits:

One component.
Cures by reaction with ground and air moisture over aa exclusive moisture-triggered chemical reaction.
Protects very efficiently, especially if a dark final colour is required.
Simple application (roller or airless spray).
Increases the abrasion and wear resistance of the waterproofing membrane underneath.
Provides high solar reflectance (white colour) contributing to thermal insulation.
EPD verified.
Gives a glossy and easy-to-clean surface.
No chalking effect.
Resistant to stagnating water, heat and frost.
Maintains its mechanical properties over a temperature span of -40 to +90°C.
The waterproofed surface can be walked on (light pedestrian traffic).
