C.R.: I'm happy with the outcome of the cement.
I made 4 refractory panels for a wood burning fireplace insert.

1) 16.5" x 17"
2) 16.5" x 17"
3) 18.5" x 18"
4) 16.5" x 31" x 20" x 16.5" (trapezoid shape)

Thickness of each panel was 1/2".

I added 1" refractory needles (stainless steel) to each panel, about 3% of weight of the panel. These are suppose to prevent cracking.

I used a total of 75lbs of the RUTLAND Castable Refractory Cement. I made molds from wood, sprayed cooking oil on each, laid down plastic, placed the mold over the plastic, mashed half the cement into the mold, spread the refractory needles, added the remaining cement and covered with plastic.

Rutland customer support said to cover all sides of the mold for 24-hours. This is to keep the moisture from evaporating so the cement sets properly.

The cement drys a very, light grey....almost white. The panels are solid and heavy.

Brian Cowan: Like that this sets up fairly fast and holds up pretty well under high fire conditions. Worth the cost.

J. Rothenberger: I had the back slab develop a 4" hole. Shut down the FP and scurried to find out how I could access it and find a replacement. Found both, placed an order and then worked on disassembling to get the slab out. A week or so later, I hadn't received shipping information so I contacted the vendor and found the slab was back ordered and would be shipped on Feb 5th.

Not trusting the actual date supplied, I started searching for possible repair solutions and found the Castable Rutland product. I'd used other Rutland products but was a bit concerned due to my lack of cement knowledge and some of the reviews I read. I decided to take a chance as the coldest part of the winter was upon us and I burn 24 x 7.

I planned my approach and in a couple days I had the cement (left input in questions about getting the top off), had a board to sit it on and some wax paper that I planned to put between the 4 " hole in the slab and the board I was putting it on. I used another stick to define the edge of the hole to be filled and a couple of bar clamps to hold everything in place. Now I was ready to go.

I brought the slab to the cellar and realized that this might just not work. The...

Amazon CustomerAmazon Customer: I'm very happy with this product, sorry some folks have a hard time with it. This is an actual dry concrete pre-mix so you *must* follow concrete rules. Follow those rules without fail (Google if you're unfamiliar) and you should have great results. Comments and opinions to follow are my own, so do your own due diligence.

The 6:1 water ratio in their instructions really is a maximum water ratio for casting into a mold where you need to fill out small or thin details at high density. I like less water even for pouring a mold, and much less for open face or trowled work. Least water for the consistency you need is good. If trowling against a dry surface, dampen the surface first and maintain dampness by quenching (wet the surface first and wait, repeat until it doesn't dry up so fast) unglazed ceramic, brick, etc. Use the peanut butter consistency or ball toss test as needed. But in any case once it stiffens, keep it damp! I add water and seal a trash bag over my freshly de-molded "green" castings and leave them in the sun if possible for at least a couple of days. My results have been very hard and strong castings with great surface density, detail, and smoothness. In the...

mark: Works as intended - for holding fire bricks together like a mortar. I was trying to utilize it to repair my forge and it did not 'stick' as I hoped it would on the forge ceiling. It did work well enough so I could continue work until the proper materials came from my forge supplier.

Brandon: Does not come with any mixing instructions and I couldn't even find any information online either which is strange. But I've used it for two different applications (a small tin can forge, mixed dry for easy packing and for a skim coat over my kaowool insulation for my gas forge mixed quite wet) and both have worked well.

The one instruction you do get is to not fire cure the cement. Listen to that. If you add too much heat to quick it blows chunks out of the surface from steam escaping.
