Mapei Mapeflex Firestop 1200°C High Temperature Sealant Grey 300ml 3.7 5 7 7
Not great Having read the product spec I thought this would be perfect for sealing up around the register plate of my stove and some joints around the cement board surround. I have however found it does go brittle and fall out of the joints after just one hot burn. Perfect if your stove is an ornament, worthless otherwise. 14 Feb 2015
Sticks well ok so this is expensive for a sealant but it is rated up to 1200 degrees C I used it to build an oven using 12mm cement board for a home made vacuum former, the oven is suspended in the air and this sealant holds the boards in well, the oven is fairly large (833mm x 625mm) and it holds a sheet in that size well so far. when using it with a sealant gun it some times feels like it gets blocked to you put a little more pressure on it and you get a big glob of it come out which is annoying and messy. it would have been nice for it to flow easily out in a controllable bead which it sometimes does. 16 Jan 2015
++++High Temp Sealant Great High temp sealant for ideal for stoves and flues. I have just used it to replace a 250/300max deg c sealant on all the joints on a newly installed log/coal burning stove. Previous sealant lasted three small fires. This was easy to apply and we have had the fire running at max efficiency 500degc with no issues now for 8 fires with no sign of cracking or break up. Great high temp sealant ideal for fires flues and boiler chambers. It would be nice if it came in other colours but was easily over sprayed. 26 Dec 2014
