Excellent product.
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.

Worth every penny.
I'm new to 'metal melting' and was advised to use this when constructing my "hot block" out of ceramic plates. This paste is brilliant, it was VERY easy to use my hot block was built in about 40 minutes flat. It's been used a few times now and its great no problems with the 'cement' its solid and should last a while. I recommend this sealant to anyone working with ceramics its brilliant and sets rock hard.

Strong stuff
Fantastic product, easy to apply and sets rock hard. Had multiple fires since installed and no sign of cracking seems durable.

Ok
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.

Producto estupendo
Me ha encantado la fijación y la unión, lo he utilizado para el cristal de una estufa de leña y me he quedado sorprendido de su prestación. Lo único es que no es muy líquido pero es un producto estupendo.

Mastice vitcas
Usato per sigillare una stufa isotta la nordica. Smontato l interno della stufa ho scoperto che era assemblata male e con materiali e viti pessimi. Ho riempito le fessure della parte esterna della stufa che beveva aria dappertutto e mi sono trovato molto bene. È una crema morbida e facile da lavorare, aderisce benissimo e incolla in modo ottimale. Ottima essiccazione e robustezza, ottimo prodotto. Ottimo

Works well for sauna stove.
It works well but keeps falling off the crack, so I have to re-patch it often.
