    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 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.
  • Please Note: In conjunction with water retaining structures, Joint former 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.
