DAP High Heat Fire Resistant Mortar, 10 Oz, Black (7079818854)

Worked really well on my fireplace box. Dried fast. Easy to use.

Good products

I have something called a little red campfire that has these parts one of which is a log set. The log set got broken and I decided to try this adhesive to do the repair. I am heat curing it by simply using the campfire. So far everything seems to be working quite well.

This high-heat mortar worked great for my project and was easy to apply. It was thinner than I expected, so it can be a little messy to work with and really likes to get all over your hands. I wish gloves were included. Overall, it performed well, filled in the cracks between bricks. Dried overnight (but I gave it a few days before I lit the fireplace), did the job, and is a good value for the price.

This product was exactly what I was looking for. My outdoor pizza oven needed some bricks back in place. It worked perfectly. Great adhesive.The price was reasonable. Arrived on time. Definitely buying again.

These went on easy enough to close a small gap in the pipe that attaches to my wood stove but even though I followed the directions and let it cure before building a fire, I have found some of the mortar has dried and flaked off leaving a fee pinholes around the pipe. I will reapply in the summer when I can leave it to cure for a few weeks instead of a few days and see if that helps. It did go on fairly smoothly and the black color blended in well with the pipe but if it doesn't hold up to the high heat it wont be worth the money.

Perfect for fixing cracked up fire pit

Comes out a little runny but has held up well and works on the cracks in our chimney. I “v’d” the cracks to get better adhesion and all is good.

Worked great for me.

I think this would be great for the right job. Bought this to try on a clay chiminea fire pit. It sealed filed in the cracks for sure but didn’t seal it the way I was hoping. I honestly don’t think it’s for this but I wanted to give it a try as I love the fire chiminea pit

Used this to repair some minor cracks and a few small broken areas of mortar in my fireplaces. It is a bit sticky, sometimes preferring to stick to the tube and to fingers rather than to the mortar, thus it was a bit more difficult to apply than I had expected. However, overall it has stayed solidly in place after several fires in the fireplace, and it looks good.

Followed the instructions perfectly but the seal gave away just after two days.
