Description
Liquid-applied roof waterproofing for new and existing flat or pitched roofs, and on flat roofs with pedestrian access.
BBA approved, certificate 17/5443.
Comprises:
- Primer, either:
- MARISEAL® 710, a solvent-based polyurethane for porous substrate penetration;
- MARISEAL® AQUA PRIMER, a water-based two-part epoxy primer for porous and non-porous substrate penetration; or
- MARISEAL® TPO PRIMER, a transparent solvent-based one-component adhesion promoter.
- MARISEAL® 250, a cold-applied and cold curing, one-component polyurethane membrane based on elastomeric hydrophobic resins. Used for base and second coat.
- MARISEAL® Katalysator, an accelerating additive for use with MARISEAL® 250.
- MARISEAL® FABRIC, a non-woven polyester reinforcement (not applicable for systems <1 mm thick).
- MARISEAL® 400, a one-component liquid-applied roof waterproofing based on aliphatic polyurethane.
