VITCASHeat Resistant Sealant - Excellent adhesion - Converts to rock - Simple to use - Heavy duty – Fixing Ceramic – Glass - Metal - 1300 C - 310ml

This is good stuff. I was installing a log burner in my workshop and used it both to seal the collar to the corrugated roofing and to seal the flue joints on the stove itself. After 6 months use the roof is 100% watertight and the stove joints show no cracking or smoke escape.I was a bit nervous about this job, I hadn't installed a log burner before, but the sealant was easy to use and has performed brilliantly. Highly recommended.

Bought it to glue the steel chimney into my home-built pizza oven. Does the job superbly.

Great product

My dual fuel stove glass on the door broke last night, and with it being in between Xmas and new year I don't know when my new glass will be delivered, and we are forecast snow, so I wanted to still be able to use the fire so tried this stuff.Really pleased, it's easy to use, seemed to bond quickly I didn't have to sit holding it or anything and hopefully it will last until my new glass arrives.

Got smoke leaking out or cold air sneaking in? This stuff stops it. Just squeeze it out, smooth it over the cracks, and let it dry. Boom—sealed up tight!It’s made to handle super high heat, so it won’t melt or crumble when your fire’s raging. And it keeps your stove safe and more efficient

Not really a sealant.. it does do the job as in it fills gaps, however it is nothing more than fire cement in a tube, so it really should be called cement, not sealant. I was expecting a silicone type product which this isn't. No good for outdoor applications or sealing anything where water egress may be a problem as it is porous.

Ideal for fitting new burner surround

Used on wood stove flue. Easy to use and great seal. Would recommend.
