Conseal 220
Conseal 220 is a water based, polyurethane hybrid waterproofing membrane that cures to a permanently flexible seamless membrane with good adhesion to a wide range of substrates. Unlike more traditional bitumen based products, Conseal 220 does not brittle with age, exposure to ultra violet radiation or weathering, and hence it does not crack or craze due to its’ flexible properties.
Description
Conseal 220 is a water based, polyurethane hybrid waterproofing membrane that cures to a permanently flexible seamless membrane with good adhesion to a wide range of substrates. Unlike more traditional bitumen based products, Conseal 220 does not brittle with age, exposure to ultra violet radiation or weathering, and hence it does not crack or craze due to its’ flexible properties.
Uses
- Suitable for use over various porous substrates including fiber cement, concrete, render brickwork, render polyurethane foam insulation and plasterboard
- It can be used to waterproof basements, kitchens, bathrooms, balconies and decks, shower recesses, repair and restoration of leaking roofs as well as a damp proof membrane in sandwich panel construction.
- It is also suitable for Deck / open roof areas, planter boxes and retaining walls provided it is protected from the effect of highly turbid water flow.
Application
Surface Preparation
Surface should be sound, clean, and free of dust, oil, grease and curing compound. Loosely adhered particles such as rust scale, cement smears should be thoroughly cleaned with a wire brush or another such implement.
All new concrete surfaces must be fully cured (6-8 weeks) with a semi-rough surface appearance. Freshly Rendered surfaces must be allowed to cure for a minimum of 7 days prior to the commencement of waterproofing and levelled to a slope.
Gypsum/Plasterboard sheets must be installed to the manufacturer’s guidelines with all joints being covered with a 50mm wide PP or PE tape whilst all screw/nail heads must be sealed with epoxy. When used as a wall substrate, sheet thickness should be a minimum 10mm thick.
Fiber Cement sheets when used as a floor/wall underlay sheets should be a minimum 6mm thick whilst compressed fibers cement sheets should be a minimum 9mm thick for walls and 15mm thick for floor applications. Ensure all Metal Surfaces are rust free with any hair line cracks being filled with a suitable gap filler whilst cracks larger than 2mm should be filled.
