Expert Verdict — Reviewed by the SuperArbor Pro Desk
Keep a box of T-joint patches on every TPO crew's cart; patching intersections before welding seams is faster and more consistent than cutting in place. Match grey patches to grey membrane so finished seams stay uniform.
Hot-air welding equipment is very hot; wear heat-resistant gloves and follow the welder manufacturer's safety instructions.
