Rated 5 out of 5 by from Brilliant Stuff Both of the firebricks in my woodburner had broken in half. Went to Screwfix and bought a cartridge of this stuff.Removed bricks and applied a good bead to each edge then squeezed bricks together and replaced them. Scraped off excess with knife. It states curing time of 24hrs, i was cold so lit fire after 6hrs without any issues, no movement no cracks, nothing.4 days have no passed and still good.

Rated 3 out of 5 by from Ok sealant Used sealant around flue pipe of log burner. Product reasonably easy to use, however I have given it three stars as it seems to deteriorate after 1-2 months of regular use of burner and flakes away. Haven't found a product that lasts any longer

Is this sealant food safe? I'm wanting something for a BBQ

Mapei Mapeflex Firestop 1200°C High Temperature Sealant Grey 300ml is a refractory grout product which is mainly designed to go in between bricks, due to this reason this product has not been tested for hygiene certification or in areas subject to food contact. Mapei Mapeflex Firestop 1200°C High Temperature Sealant Grey 300ml is also not suitable for external applications.

Can this Product be used to seal two parts of a very old heat exchanger that has the burner underneath?

Asked by: metaljunkie
Mapei Mapeflex Firestop 1200°C High Temperature Sealant is not a flexible sealant and therefore should not be applied to surfaces that may expand and contract such as metal. This product 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.
