- Ensure all concrete surfaces are free from base grit and dust.
- Apply glue in vertical strips ± 100 mm wide and 25 mm from the
top to avoid the
tear-off strip from sticking to the concrete face. - Allow the glue to dry (according to manufacturer’s instructions)
and then stick
Joint former onto the glued concrete face. - Cast the next section of concrete as required. Take care not to let the wet concrete
get behind Joint former as this will result in a wavy joint. - When the joint sealant is about to be applied, simply peel the
tear-off strip out of the
formed joint, leaving an even groove of uniform depth for filling with sealant. - Joint former has good compression qualities with good recovery capacity.
- Joint former is supplied with a hinged temporary blocking piece,leaving a clean, neat
and perfectly sized groove providing a consistent depth channel for joint sealent. - Joint former is cut to size, eliminating wastage and cutting on site.
- The Joint former material is flexible and can be used around corners.
- Joint former Excellent resistance to chemicals.
- Joint former is waterproof, does not disintegrate, rot or swell.
- No bond breaker required.
DIRECTIONS FOR USE
Please Note:
In conjunction with water retaining structures,
Joint former must NOT be used where the water head is in
excess of 3 metres.
The correct size to be used depends on the condition of the formwork or type being used:
