Rated 5 out of 5 by from Better than Fire Cement! Great stuff to use, bit pricy but worked a treat reconnecting our wood burner. A word of caution it's pretty runny, more like toothpaste than silicone! Easy to apply and seems to do the job a lot easier than traditional fire cement, thicker bits cured after a few hours and we'll see how it performs once the burner is fired up again!

Rated 5 out of 5 by from Great Product Used this grout on my bbq to seal angle iron which holds my smoker lid. Dries rock hard after 24 hours and works perfect, easy to apply and easy to clean after use. I am very pleased with this product and would definitely recommend.

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.
