Substrate Preparation
Any damage to the surface should be repaired prior to application, using patching mortar. Joints must be clean, dry, and free of dust, oil, paint, or any surface contaminants. Joint sizes may range from 3-12 mm in width and 5-10 mm in depth. The width should be wider but smaller than the depth, for better elongation. Bond breaker may be used to adjust the depth/width ratio. Masking tape should be used on both sides of the joint to control joint width.

Estimated Coverage

Application
Cut away the top part of the threaded end of the cartridge and plastic tip. Position the cartridge in a manual or air powered caulking gun. Squeeze out one or more beads,depending on the width of the joint to be filled. Remove the masking tape before the sealant cures (within 20 minutes).
