Mark out and cut your PVC patch . Cut patch to extend at least two inches (40-50 mm) beyond the tear. Round the edges, square cornered patches are more likely to catch and peel than rounded ones. Trace the outline of the patch on the damaged surface with a pencil. Lightly buff both contact and gluing surfaces, using fine sandpaper, ~ 180-grit, or a roller rasp. Just buff the fabric shine off; don't rasp down to the threads. Clean the buffed surface with the lint free tower or pvc cleaner .Allow areas to dry .
BEFORE YOU START ANY GLUEING PLEASE NOTE
YOUR WORKPLACE NEEDS TO BE WELL VENTILATED, WARM AND DRY. IF THE AIR IS HUMID DON'T TRY TO USE THE ADHESIVE AS IT WILL BLOOM. DO NOT USE A GAS FIRE OR NAKED FLAME HEAT SOURCE AS THE SOLVENTS ARE HIGHLY FLAMMABLE. DO NOT USE THE ADHESIVE IF IT HAS BEEN MIXED FOR MORE THAN 4 HOURS.IF THE DAMAGE TO YOUR TUBE IS MORE THAN 15MM IN ANY DIRECTION AN INSIDE PATCH NEEDS TO BE APPLIED. THE PROCEDURE IS THE SAME BUT IS MADE MORE DIFFICULT BECAUSE YOU ARE WORKING ON THE INSIDE OF THE TUBE
Apply one even coat of adhesive to each surface.
Although the material may be bonded while wet, optimum results are achieved when waiting 3-5 minutes before bonding the surfaces together.
Carefully align the patch and press both surfaces together. Apply pressure to the entire glued surface using a roller. Roll every millimeter of patch in multiple directions, working from the inside to the outside of the patch. You must make sure that there is no air trapped between the surfaces.This step is important because it forces air bubbles out and helps the two pieces of material bond.
Use a lint free towel and PVC Cleaner to wipe up excess glue.
Complete curing time takes approximately 24 hours.
