Application Instruction
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.
