Tips for multi-joint jobs
- Dry-fit everything first and mark alignment lines with a marker.
- Work one joint at a time. Fast-setting cement doesn't give you time to adjust.
- Keep the lid closed between joints so the cement doesn't thicken.
- Use the right dauber size for your pipe diameter.
- Wipe off excess to keep the job neat.
Curing before pressure testing
Fast adhesion doesn't mean full strength. Follow the label's cure times before pressurising, and allow longer in cool or damp conditions and for larger pipe sizes.
Storage
Store upright in a cool, shaded place with the lid tight. Thickened or jelly-like cement should be replaced.
Need prep? Use Lanco PVC Cleaner or a purple primer cleaner before cementing.
