DamagedArea
The Coating Repair Patch (CRP) is typically shipped inbulk rolls and can be cut-to-size in the field. Mastic Fillersare used to repair holidays and/or fill voids.
Use a low intensity yellow flame for pre-heating the coatingand applying the repair products. With quick back and forthstrokes, pre-heat repair area to 60˚C minimum to removemoisture and assist in adhesion.

Pipeline Repair Products
Place the filler material onto the damaged area with therelease paper facing up. Firmly press the material into thedamaged area by hand and remove the release paper.
Pre-Heat
Warm the damaged area (repair zone + 50mm (2”)overlap) to remove moisture and assist in adhesion.

Overwrap Patch
Spirally overwrap the patch with UCC PVC overwrapextending about 150mm either side of the patch.

Patch Installation
After removing the release liner from the cut patch, place thepatch with the adhesive side up on a gloved hand, or on topof the pipe, and heat gently. Heat until the adhesive softensand the surface becomes glossy. Also, reheat the damagedarea to keep it warm.
10
Patch Preparation
Cut a patch of CRP large enough to extend a minimum of50mm (2") beyond the edge of the repair zone. Trim eachcorner of the patch about 10-25mm (½" - 1") at a 45° angle.If the damage has a diameter greater than 10cm (4"), use anappropriate heat-shrinkable sleeve.
