Good stuff, work great!

I tried another brand before this, and found them to be GRITTY and inconsistent with bonding and likely to be very weak in tension. Girtech, however, is very smooth, mixes well without voids, and really sets up hard (particularly if you use reinforcing framework) and strong. I would say that pound for pound, Girtech mixes more product volume. Unlike the competitor, Girtech has a second ingredient bag inside which must be mixed carefully. Sets up very hard and very strong quickly! Very smooth end result!

The first bag of this I got had a bunch of trash and was half rocks instead of cement so I requested a replacement. The 2nd bag was pretty good, it had a few little rocks and no trash. It set up good and has lasted good so far. Used to repair a wood stove.

I just tore apart the first foundry I built using this in order to rebuild it and I struggled to get some of these bricks to come apart neatly simply because the refractory cement was doing exactly as it was supposed to and held them together like the fate of the universe depended on it. My foundry was able to get up to 2,700°, and using this refractory cement I was able to place my bare hand on the 80° exterior. It ain't cheap, but it's worth it.

this is NOT CEMENT! this is fiber reinforced concrete. big chunks of aggregate and even bigger clumps of fibers- which ruins the finish. NOT GOOD AT ALL for molding. I have no earthly idea why this is marketed as castable. it is so brittle until you fire it. I don't know of any molds that can take the heat. it broke apart trying to de-mold it and I followed the directions perfectly. What a WASTE of money. this stuff is way too expensive for how garbage it is.

Used to repair liner in a wood boiler that was no longer available from the manufacturer. I used a heat lamp to cure after I cleaned and moistened the area. It has held up so far through more than a dozen burns with no problems. The minimum thickness you can form or cast is about 3/8” which is the size of some of the aggregate

fixed woodstove cracked cast iron door support Vermont castings saved wood stove from junk pile , even though door frozen now at fixed opening about right for my stove . brfore all the heat went up the chimney Been to 800 F multiple times no x changrs or cracks - tough stuff Follow directions exactly

Difficult to mix and once dried, it cracked. I tried several different consistencies but still cracked. Not a top DIY pick. Maybe a pro would have better results

Le colis est fidèle a la publicité et le temps de livraison est respectée . Merci

Like my headline says read the directions! We did not so sadly this product did not work for us.

Good product but instructions were missing some details. Contacted manufacturer and got the info

Used for a pizza oven. You absolutely need insulation like this between fire brick and concrete or your floor never gets hot enough

Don’t even waste your time it’s actually the worst thing I’ve purchased. I think actual dirt with water would do better than this.
