Join Two Pond Liners Together

How to Repair or Join 2 or More Pond Liners Together Using our Splice Kits

 1.  Lay out two pieces of pond liner to be spliced together with at least a 7" overlap of the two pieces.  Mark the overlap with colored chalk to establish a "line" for primer/activator and seam tape application.

 2.  Use a 3" stiff brush to apply a full coat of primer/activator along the "line".  Apply to both sheets, bottom sheet along the mark, and top sheet on the underside overlap area.  Note photo 3.

splice 4.jpg (30172 bytes) 4.  Apply 3" seam tape to bottom sheet in an "unroll" fashion, using the opposite hand to press the seam tape into contact with the bottom sheet.  Avoid any wrinkles, and make sure to keep the roll taut as you unroll the tape into position on the bottom sheet.
splice 5.jpg (27657 bytes) 5.  Use a small steel roller to roll the seam tape into GOOD contact with the bottom sheet.  Also, apply a bead of water cut off (gray color) or lap sealant (black color) about 2-3 inches from the seam tape on the underside sheet.
splice 6.jpg (29748 bytes) 6.  Start at the one end of the bottom sheet, and peel up the wax release paper from about 6 inches of the bottom tape, making sure NOT to peel up the 3" seam tape from the bottom sheet, and do not tear off the wax paper.   Next, totally "flop" over or fold the top sheet on the bottom sheet so the entire seam area is covered with the top sheet.  Next, start "brushing" with your hand the top sheet onto the lower sheet, and at the same time start pulling the wax paper off the tape from the bottom sheet as you are "brushing" the top sheet onto the underside sheet.  Continue down the seam the entire sheet in this fashion, pulling the wax paper as you use the brushing motion.

Application of 5" Cover Tape
   
splice 51.jpg (28033 bytes) 1.  Use a 3" stiff brush to apply a full coat of primer/activator along both sheets of the overlap area.  Sheets should have at least a 6" overlap.  It is best to have at least an area of 8" primed, to help insure that you have enough primed sheet for the application of the 5" cover tape.
splice 52.jpg (27006 bytes) 2.  Allow the primer to "flash off" or become totally dry to the touch.  Usually about 10-15 minutes in 75-85 degree sunny weather.  Allow a longer period of time in humid, cool, and or cloudy weather.
splice 53.jpg (32812 bytes) 3.  Apply the 5" cover tape over the lap area of the 2 sheets in an "unroll" fashion, using a second person to help align the 5" tape, and to press the tape onto the 2 sheets.  Avoid any wrinkles, and make sure to keep the roll and wax paper pull taut as you unroll the 5" cover tape into position.
splice 54.jpg (32652 bytes) 4.  Use a small steel roller to roll the cover tape into the 2 sheets to achieve GOOD contact
splice 55.jpg (31169 bytes) 5.  Use our lap sealant to seal both edges of the 5" cover tape.
