POLYBIT Polyseal CR PG
2 part chemical resistant polysulphide joint sealant

Pouring grade: Polyseal CR pouring grade is supplied in preweighed two parts pack, which requires on site mixing by pouring the hardener (Part B) into the base (part a) pail. Mix the material thoroughly with a slow speed drill (300-400 rpm) fitted with a flat bladed paddle for 1-3 minutes till a uniform colour and consistency is achieved.DO NOT PART MIX. Since the base and the curing agent ratio controls the ultimate physical properties like adhesion, durability and strength, one complete kit has to be mixed at a time. The side and base of the container shall be periodically scrapped with a scrapper to ensure that the curing agent is properly dispersed and blended into the mix. Load the gun grade sealant immediately into the barrel gun by a heavy duty follower plate. Start extruding into the joint firmly by maintaining an even pressure on the trigger of the gun. On vertical joints, sealant extrusion shall start from the bottom of the joint and continued to the top. For deep vertical joints, the sealant shall be filled in 2 to 3 applications in order to avoid air entrapment and sagging. The pouring grade material can be poured directly into the joint from the pail. Once the sealant has been installed a suitable rounded tool soaked in a soapy water solution can be used to achieve a smooth hour glass profile. Any masking tape applied should be removed immediately after the sealant is installed
