Rutland Products Black, 32 fl oz Furnace Cement

Used it to rebuild our wood burning fireplace with fire bricks.

Worked great for filling some cracks in my fireplace. I also used it to secure my cast iron ash pit door into place better and it worked perfectly. I would definitely recommend this product for usable. Holding up as well and I have a large fire nightly. 👍👍

I decided to use it as a paint as the old firebricks are in rough shape and mortar was missing from quite a few spots. It worked for the most part. It will probably start cracking where it bubbled but after a few more fires I’ll break some off and paint it.(Photo is: Top: freshly applied. Mid left: dried after two days. Mid right: after burning a fire per the directions. Bottom: vacuumed with rack and ash pan put back in place.)

I use this on my furnace had a small crack filled it in from both sides no problems. Had a small exhaust leak on my car I wrapped the wire mesh around the pipe and slap this all over it. No more leak LOL I'm thinking about cracks in the sidewalk next or in the foundation multi use

Found a great DIY video on YouTube that recommended this product. My 1985 fireplace insert had spalled cement on the walls and floor. Repaired both in about 20 min with this product, then covered with a fireback plate for extra protection.

Bought this to fix a broken Big Green Egg fire ring. Product easy to use and apply. Has held the fire ring together since applied. Would recommend for this application.

Great product just have to figure out what works such as tools or double gloved and use your fingers and hands.

This stuff is good. It works ok. But with any cement product I have tried to use on my wood stove, eventually it heats up and cracks off. This stuff was no different. It applies easy and cures within a day. But as with all the other products I have tried it will not last under high heat. Eventually it just gets solid and brittle.
