APPLICATION INSTRUCTIONS;

Preparation of Substrate: All joints should be dry, free from dirt, dust and grease. Cleaning should be carried out by wire brushing or grinding. Joint sides must be parallel and straight. Before positioning a bond breaker ensure that the expansion joint filler is tightly packed and no gaps or voids exist at the base of the slot to be sealed.
Priming All surfaces should have one coat of *Uniseal Primer P2 applied and allowed between 15 minutes and 2 hours to dry. The mixed Uniseal 200/90 Coldpour should be applied when the primer is tack free.

Add the entire contents of part B to part A and mix for a full 5 minutes using a slow speed drill with paddle type stirrer until a completely homogeneous mix is obtained. Mixing is made easier if Part B is added and mixed in two stages. Care should be taken to prevent unmixed material remaining on the sides of the container. The sealant is then applied to the prepared joint void to finish 5mm below the surface. Use of masking tape will help to obtain a clean finish. The sealant should not be applied at temperatures below 5o C. For aesthetic purposes very light tooling of the joint material as it gels releases surface bubbles and enhances appearance.

Please Note: If application of Uniseal 200/90 Coldpour is delayed for more than two hours after priming, joints should be re-primed.
