The edges of the joint to be sealed must be clean and should not contain any oil, grease, dust dirt or moisture. Fill the sealant along the joint to be sealed taking care not to form any air pockets, and there after tool the joint to a smooth surface with a suitable spatula. A bond breaking tape needs to be used to ensure that the sealant does not contact the bottom of the joint. The joint width to depth ratio may be maintained at 1:1 up to 15 mm width and thereafter joint width to depth ratio could be 2:1. Clean the equipment and tools immediately after use when the sealant is still wet with ethyl acetate or a suitable solvent.Upon drying it can only be cleaned by mechanical means.
