Jointex

Description

Colours: White

A closed cell expanded polyethylene joint former with a hinged temporary blocking piece is provided. The product is cut to size according to the specified dimensions. Ensure all concrete surfaces are free from grit and dust. Apply glue in vertical strips, 100 mm wide and 25 mm from the top, to prevent the tear-off strip from adhering to the concrete face. Allow the glue to dry according to the manufacturer’s instructions, then adhere Jointex to the glued concrete surface. Cast the next section of concrete as required, ensuring that wet concrete does not get behind Jointex to avoid creating a wavy joint. When ready to apply the joint sealant, peel off the tear-off strip from the formed joint, leaving an even groove of uniform depth for filling with sealant. Used as a former for expansion and contraction joints.
