DIRECTIONS FOR USE
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 Jointex® onto the glued
concrete face.
Cast the next section of concrete as required. Take care not to
let the wet concrete get behind Jointex® 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.
Please Note: In conjunction with water retaining structures,
Jointex® must NOT be used where the water head is in
excess of 3 metres. Use Aquajoint (SPX 120) for applications where the
water head exceeds 3 metres and is not more than 15 metres.
