INSTALLATION PROCEDURES

JOINT PREPARATION The joint surface must be clean, dry and free from oils, loose mortar, laitance,
release agents and other contaminants. A thorough wire brushing, grinding,
sand blasting or solvent cleaning may be required to expose a clean and sound
surface.

PRIMING Primer should be applied to a clean, dry surface prior to installation of backer
rod and/or bond breaker tape. Polyseal Primer is recommended for most
common substrates like concrete, tiles, etc. For non-porous substrates like glass
& steel, special primer can be applied to achieve optimum adhesion. Where a
particularly neat finish is required, apply masking tape on both sides of the joint
before priming and remove immediately once the sealant application is
complete.

BACKING MATERIAL Closed cell polyethylene backer rod should be used to control the depth of the
joint sealant to the recommended thickness. Where joint design or depth of
joint will not permit the use of backing rod, use a bond breaker tape.
