Application

Top coat for use over MARISEAL® waterproofing membranes on:

  • Roofs;
  • Protection of polyurethane foam insulation.


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

Description

Water-based, pigmented, wear resistant, semi-rigid, colour and UV stable polyurethane coating, used as a top coat for protection over water-based waterproofing membranes.

Based on the innovative PUD-Technology™ of Maris Polymers SMSA.


Features and benefits:

  • One component, water-based aliphatic polyurethane.
  • Simple application (roller or airless spray).
  • Forms a hydrophobic, 100% waterproofing, seamless polyurethane coating that protects the waterproofing basecoat efficiently and on a long-term basis.
  • Resistant to abrasion.
  • Provides high solar reflectance (white colour) contributing to thermal insulation.
  • EPD verified.
  • Gives an easy-to-clean surface.
  • No chalking effect.
  • Resistant to frost.
  • Maintains its mechanical properties over a temperature span of -30 to +80°C.
  • Low VOC content, <100 g/L.
