Conseal 220 is 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.
- Suitable for use on many porous substrates including ﬁber cement, concrete, render brickwork, render and plasterboard.
- It can be used to water/damp proof 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 areas & is also used in planter boxes and retaining walls as long as it is protected by drainage.
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. Concrete all new concrete surfaces must be fully cured (6-8 weeks) with a semi-rough surface appearance. Rendered surfaces must be allowed to cure for a minimum of 7 days prior to the commencement of waterprooﬁng. All surfaces must as level as possible with a slope variation not exceeding 4mm.
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.
