+30 22620 32918-9 Website

Application

Liquid-applied roof waterproofing for new and existing flat or pitched roofs, and on flat roofs with pedestrian access.

Can be used with the following substrates:

Concrete; mortar; ceramic; insulation; steel; EPDM and bituminous waterproofing membranes.

Decks to which the system is to be applied must comply with the relevant requirements of BS 6229:2018.

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.

Specification data - Liquid-applied cold roof covering systems

System performance	High performance waterproofing system.
Preparation	-
Horizontal work	MARISEAL® 710. Guidance for specification option: A solvent-based polyurethane for porous substrate penetration. Coverage rate: 200 g/m² in one layer. MARISEAL® AQUA PRIMER. Guidance for specification option: A water-based two-part epoxy primer for porous and non-porous substrate penetration. Coverage rate: 100–200 g/m² in one or two coats. MARISEAL® TPO PRIMER. Guidance for specification option: A transparent solvent-based one-component adhesion promoter that activates EPDM membranes. Coverage rate: 5–60 g/m².
Skirtings and vertical work	As Horizontal work.
Liquid-applied waterproofing	-
Type	Base coat: MARISEAL® 250, 1.2 mm thick. Second coat: MARISEAL® 250, 1.2 mm thick (over reinforcement). Guidance for specification option: The second layer should be applied 12–18 hours after the base coat and no later than 48 hours after the initial coat. Application can be by brush, roller or airless spray. Brush application is normally only used for small roof areas and for embedding the reinforcement into the waterproofing. Consult manufacturer's literature for detailed preparations requirements. Manufacturer guidance Specify visible colour (second coat) below - see Top colour.
