Pipe Repair

A controlled structural repair system for rigid pipe. Mix true 1:1, build it past the damage, clamp it — put it back in service in 24 hours.

03The method

The method is the product.

1 · PREPARE
Clean, dry, sanded — in that order.
2 · PURGE
Purge the cartridge until both sides flow even.
3 · MIX — TRUE 1:1
One uniform color, no streaks.
4 · BUILD
Build past the damage — extend 0.5–1″ beyond every edge.
5 · ALIGN
Set the parts in position.
6 · CLAMP
Clamp it through the set. Bring your own clamp.
7 · CURE
Hands off for 3–4 hours. No load before 24 hours.

04Honest limits

The repair won’t be invisible — but it will be stronger than the pipe was.

Not for polyethylene (PE), polypropylene (PP), PTFE, silicone, soft or flexible parts, fuel and brake lines, exhaust manifolds, or pressure-critical and safety-critical repairs. If it is safety-critical, replace the part — don’t bond it.

05Longevity

“Fix it tonight. It holds for years.”

Questions

How long until I can use the pipe?+
Up to 30 minutes working time, 3–4 hours initial set, and 24 hours before the repair takes load or pressure.
Does it bond damp surfaces?+
Yes — it bonds damp, properly prepared pipe interfaces and cures into a hard, waterproof body.
Do I need a caulking gun?+
No. A push rod is in the box and does the job. A standard caulking gun is optional.
What if the repair fails?+
Follow the method card — if the repair fails within 30 days of delivery, you choose a full refund or a free replacement box. How to claim →
