Seam Repair Instructions

Step 1: Layout the Liner
Layout the sections of liner to be seamed. Overlap ends 6" - 12"

Step 2: Clean the Seam Area
Lift the top liner. Use gasoline and thoroughly clean the seam area

Step 3: Mark the Seam Area
With the top liner down, use a crayon or lightly score with scissors, the seam area on the bottom liner. Raise the top liner in the preparation for priming

Step 4: Prime the Seam Area
Prime both liners. On the bottom liner, prime an area 1/4" above the mark, approximately 6" - 8" wide. Prime a matching area on the top liner

Step 5: Apply 3" Double Stick
Apply 3" of double sided tape to the bottom liner, pressure rolling as you go to eliminate air bubbles or wrinkles

Step 6: Smooth the Seam
With the double stick paper still on, replace the top liner and pressure roll the seam

Step 7: Seal the Seam
Slit the double stick tape at the middle of the run of the seam. Overlap the liners and carefully remove the paper, pulling off the tape from between the liners at a 45 degree angle, one side at a time

Step 8: Apply 6" Single Stick
Prime an area 6" wide spaced evenly over the exposed edge of the seam. Apply 6" tape over primer

Step 9: Roll and Seal Forever
Thoroughly pressure roll the 6" tape and generously apply lap sealant along both edge of the 6" tape

Step 10: Apply 6" Single Stick
Allow the seam to dry thoroughly before contact with water
