How to prepare a surface for bonding with PC-Xtreme™

Substrate and environment must be completely dry without any presence of moisture prior to usage. Blow out and remove all dust, dirt, debris, oil and any other contaminant from the control joint or crack. Use backer rod or kiln dried sand prior to application of adhesive. To fill cracks, use a saw or grinder with a dry diamond or concrete abrasive blade and cut along the crack opening it up to 3/16 in. to 1/4 in. wide. The edges must be a 90° angle to the surface to avoid a feathered edge.

Heavy Duty Traffic Areas: The joint width should be a maximum of 3/4 in. (19 mm). The depth should be a minimum of 3 times the width, or 2.2 in. (57 mm).

Light Foot Traffic Areas: The joint width should be a maximum of 3/4 in. (19 mm). The depth should be a minimum of 1/2 in. (13 mm).

To repair a control joint, fill all spalls with PC-Masonry™ or PC-Concrete™ and allow to cure. Recut the control joint to remove all filler materials and to reshape the spall repairs.

DO NOT use in Expansion Joints. Use for exterior and interior control joints or moving cracks. Concrete should be at least 28 days old, or at a minimum, all release agents must be removed and bonding surface must be dry. PC-Xtreme™ is not intended for joints subject to greater than 10 – 15% movement.

How to clean-up after PC-Xtreme™ application

Always wear appropriate protective equipment such as safety glasses and gloves during cleanup. Clean uncured materials from tools and equipment with mild solvents. Cured material can only be removed mechanically.
