OB1 Waterproof Tanking Solution is a one-part waterproof liquid tanking membrane applied by brush or roller over stable surfaces & structures, protecting them against moisture penetration through a tiled surface in locations such as wet-rooms, showers, bathrooms, kitchens & utility rooms where existing surface cracks & joints are no wider than 3mm. When used in conjunction with reinforcing joint tapes & gaskets, this combination provides the added protection (in compliance with EAD 030352-00-0503) needed to bridge & cover cracks & joints where possible structural movement & vibration is likely to require sealing across wider gaps & joints over 3mm.
CHARACTERISTICS
- Easy to apply with brush or roller
- Protective waterproof under-tile coating
- Flexibility accommodates movement & vibration
- Forms a strong bond to most wall & floor surfaces
- Suitable for use beneath immersed tiling
STORAGE
Store in dry conditions. Do not store or apply in
temperatures below 5°C or greater than 30°C.
APPLICATION
Using a brush or roller, liberally apply the first coat to all wall, floor surfaces & structural joints, pipe inlets & gully areas. Once the first coat is dry, apply a second coat at the above rate and allow to dry. Where movement is likely to create wider gaps or joints (>3mm), cut reinforcing tape to size and press the pre-cut tape across all joints whilst the first coat of OB1® Waterproof Tanking Solution is still wet, smoothing down the tape as you go, forcing out any trapped air and repeat this procedure where the pipe entry gaskets are being fitted.
When all tapes & gaskets are securely in place apply a second coat at 0.5kg per m² across the full area of the floor and walls (including over the taped joints & inlets) and allow to dry. Allow 2 hours before tiling, a full 24 hours may be required for unheated areas.
