Our Fire Rated Duct Sealant is widely used in the air conditioning industry. This product is considered by many to be the benchmark for all other duct sealant products. It has just the right thickness for application to all types of ductwork without runs and providing good coverage of any leaks. Just try to get it off once it’s fully cured, you won’t believe it!

It comes in any colour you want as long at the colour you want is grey!

It complies with the fire and smoke developed indices required in Australian Standard AS4254 (Does the one your using?)

If you are into saving time, use it straight from the 4 litre container with a brush. If you’re not in a hurry, but need to apply in a tricky location use or 320ml caulking tubes.

Use it for other applications, be inventive. We have seen it used to repair gutters, seal concrete floors and plinths. One of our customers used it a couple of years ago to seal a concrete fishpond and we’re told it hasn’t leaked yet. And yes it is true; one of our guys used it (and a piece of old rag) to repair the rust hole in the boot of his car (Two pack paint went straight over!).

If you have a novel use, give us a call. We cannot believe some of the stories.
