How to Repair Geomembrane Liners with HH-66
HH-66 is safe and simple to apply on PVC liners. Follow these three steps for a seal that won’t fail:
Prepare
Cut a vinyl patch with at least 2 inches of overlap on all sides of the damaged area. Round the corners to prevent peeling. Clean the area with alcohol or our HH-66 Thinner.
Apply
Spread an even layer of HH-66 Vinyl Cement on both surfaces. Let it sit until tacky (about 2 minutes).
Attach
Press the patch firmly onto the damaged area. Apply even pressure throughout to smooth out air bubbles. Remove any excess adhesive. Let it cure for at least an hour before use. Full strength is achieved in around 24 hours.
