Solvent Cleaning5
Clean exposed steel and adjacent pipe coating with anapproved cleaner (as per SSPC-SP-1) to remove thepresence of oil, grease and other contaminants.
Surface Preparation6
Remove adhering rust, coating chalk, dirt, and roughen themill applied coating in the repair zone using an abrasivepaper/cloth or wire brush.

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.

Mastic Filler Installation
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.
9
Overwrap Patch
Spirally overwrap the patch with UCC PVC overwrapextending about 150mm either side of the patch.
13
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.

Apply the softened adhesive side of the patch to thedamaged area and press down firmly. Heat the patch with alow intensity flame, and using a roller or a gloved hand, patdown and remove wrinkles. Roll to ensure a good bond.
11
Inspection12
Visually inspect the installed patch for the following:1. Patch is in full contact with the pipe coating.2. There are no loose edges.3. A successful patch has adhesive flow on the edges.4. The patch has fully conformed to the coating.5. No cracks or holes in patch backing.
Backfilling Guidelines
After application, allow the repaired area tocool before backfilling. To prevent damage tothe repaired material, use selected backfillmaterial (no sharp stones or large particles).
14
After filling the damaged area, remove the excess filler tocreate a smooth surface. As an option, use a low intensityyellow flame to warm the filler material and assist insmoothing it out.
