Rated 5 out of 5 by Easy to buy, easy to use I was searching for this to repair a leaking flue surround, and struggled to find what I needed until I visited the ScrewFix website. This was purchased on line and collected later the same day. I applied it the following day and found it really easy to use. I've only reduced the rating for effectiveness because it hasn't been tested with either a REALLY heavy or prolonged downpour yet!!! 25 Jan 2016
Rated 4 out of 5 by High Temp Sealant Needed to seal joint in flue from oil boiler as fumes getting in to kitchen. The sealant seemed rather runny as it was applied to the warm flue but quickly dried. So far there is no smell of burnt oil fumes in kitchen, so it has done what I wanted it to do. 5 Dec 2015
Rated 2 out of 5 by Out of Date After struggling to use a lumpy dry product it became apparent I had been sold a 3 month out of date product. 13 Nov 2015
Rated 1 out of 5 by 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

Answer: 
Mapei Mapeflex Firestop 1200°C High Temperature Sealant is designed as a rigid refectory mortar to be applied between gaps in porous surfaces such as brickwork in areas that are exposed to high temperatures. This product is not a flexible sealant and therefore should not be applied to surfaces that may expand and contract such as metal.
