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!

Used it to make a kiln. You may want to add more water than it says in the instructions. I also didn’t exactly follow its instructions for heat curing but did my best by slowly heating it. It has performed really well. Very strong, still uniform and no cracking. Heated to 2900 degrees and it didn’t care. Good stuff. I also ordered the 20lb bag and they sent me a 30lb bag. No complains here as I used it all.

I used this compound to make pedestals for crucibles in a propane foundry. I ran it twice at lower temps and the edges chipped a little but held up for the most part. The issue came when I ran the third time at higher temps, around 3000F, and it held up at first but as it cooled it developed a small crack, and I picked it up afterwards and it broke. I guess its not too bad for more normal temps (aluminum and brass) but for my application it wont do.

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

Great product. Easy to work with

TERRIBLE product! DO NOT BUY!!!!!! The bag I received had holes in it, so when opening it dumped everywhere. After attempting to mix it with the awful instructions, it was not sticking to my forge at all, it was just falling off. It also set extremely fast which made it very hard to work with. Save your money and do not buy this product, look elsewhere.

Easy to work with and would buy again if it was a little cheaper
