Rutland Dry Mix Refractory Mortar, Masonry & Fire Brick Cement, No Heat Cure Required, Dark Gray, 2550F, 2.5 lb Tub

This was amazing. I did a patch on my parents fireplace. Once you mix it, you have 1 hour to complete the job and it was plenty of time. I had a ton left over. I patched all the fracture cracks and a sizable crack at the bottom. It held. I did this 5 months ago! Great product!!! I followed the directions, which were pretty simple. Set a timer and went to work.

Works great, got the job done and all season has no issues. Holds up well.

The mortar was easy to mix, & also easy to spread. After building a fire, the floor of the fireplace still looked good.

Used product to cover ceramic blanket in a homemade forge. Worked better than expected. I expected shrinking and cracking, while there were a couple hairline cracks they were insignificant and will not impede the use of the forge. I Like the product and will use again.

This is mortar so no rocks, works great and is very strong. I patched cracks and holes in my kiln and this product is the best

Used this to seal off cracks and a hole in a zero clearance firebox Product needs to cure with some heat for a few hrs. Will not sag on vertical surfaces

We ordered this to repair some cracks in our fireplace box. It mixed well and was easy to apply. It dried in about 2 hours but we waited till the next day to build a fire. It worked great will definitely buy again.

I've ordered a couple of 10# buckets they came in boxes. This one came in a bag and part of the lid was off so the mix was everywhere. When I opened the bag the dust cloud went all over. Being a cancer patient currently in therapy, I really didn't appreciate that. This stuff should NEVER be shipped in a bag only in boxes.Other than this issue, the product is good. So 2 star.
