Polyurethane Based Top Coats

MARISEAL® 400
Aliphatic Polyurethane Top‐Coat, UV‐stable Normal Pedestrian Traffic Areas

Product Description

The MARISEAL® 400 is a pigmented, color‐ and UV‐stable, highly permanent elastic, cold applied and cold curing, one component aliphatic polyurethane coating, used as a top‐coat for protection over exposed, polyurethane waterproofing coatings.

Cures by reaction with ground and air moisture over a unique moisture triggered chemical reaction. Protects very efficiently, especially if a dark final color is desired.

Uses
  • Waterproofing of Roofs
  • Waterproofing of Balconies, Terraces and Verandas
  • Waterproofing of Pedestrian Decks and Walkways
  • Protection of Polyurethane Foam Insulation
    Used over the MARISEAL® 250, 250FLASH, 250AQUA, 260, etc. on surfaces, with normal pedestrian traffic (e.g. Roofs, Terraces, Balconies, etc.) that require a glossy, color‐stable and non‐chalking finish.

Consumption

0,120‐0,250 kg/m2 in one or two layers. This coverage is based on practical application by roller onto a smooth surface in optimum conditions. Factors like surface porosity, temperature, humidity, application method and finish required can alter consumption.

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

Packaging

The MARISEAL® 400 is supplied in 10 kg, 20 kg pails in white and gray colours.

Other RAL colors may be supplied on demand.
