Admix PU700

Surface preparation
Surface should be sound, stable, clean and free from paint, oil, grease, contamination and dust. Removing laitance and grout is very important. In general, tensile strength of concrete surface should be 1.5 MPa. For the joint sealant proper function, it is essential that bond breaker tape or polyethylene closed cell backer rod be used to regulate joint depth and prevent three sided adhesion.

Joint design
To ensure long term performance, the depth of the joint should be designed to be approximately half of the width especially on joints >25mm wide.

Priming
On well prepared dry, sound concrete older than 28 days, masonry, metal or glass surfaces primer is not required. Metal surfaces should not be greasy.

Applying
ADMIX PU700 is supplied as a ready to use product. Cut one end of the foil and place it in a manual or pneumatic gun and apply immediately. The product should be tooled smooth with a spatula and non-alcoholic liquid to create a concave surface free of bubbles. It can be applied directly both horizontally and vertically.

Note: Before applying sealant, joint surrounding area must be covered by paper tape. Clean the surfaces immediately after completion of the job.

Packaging
ADMIX PU700 is supplied in 600 ml cartridges.

Storage
ADMIX PU700 must be stored under cover out of direct sunlight and protected against rainfall and moisture at normal temperature. Shelf life is 12 months if stored in stated condition.
