Rutland Products 211 Dry Mix Refractory Cement, 10 Lbs, 10 Pound

Mixed well and spread easily. Used for a parge coating on some damaged firebrick.

it worked as expected.

This cement is pretty easy to prepare, just add water until it’s the consistency you want for the application. I put it in my forge to cover a ceramic fiber blanket and prevent the fibers from escaping. In the areas where I only put a thin layer down, there are some slight cracks that formed under heat, but the pieces aren’t falling off or anything, just tiny lines formed. In the areas with a thicker layer of cement, there are no cracks at all, so the thicker layers are better and will definitely be able to handle the heat. The forge gets hot enough to turn steel glowing yellow-orange, so the cement can handle quite a bit of heat like advertised. This product contains a lot of cement powder, so if your application is relatively small like building a forge, there is way more than enough cement powder to get the job done, kind of wish they sold a much smaller container of this stuff. The cement cures very easily, just put a fan on it or leave it outside for 24 hours before putting under any heating and it will be good to go. This cement was also much cheaper than a lot of the others on Amazon and advertised greater max temperature conditions. Would definitely recommend for forging and other applications!

This product works well for fire brick re-pointing. I've used some that were pre-mixed and packaged in a caulking tube, but they failed after a couple of winter seasons of using the fireplace. Only complaint is that it sets-up pretty fast, so mixing a limited amount with cold water and working quickly is the best approach. I'll see how long this holds up, compared to other products.

Had some renters douse my firebox with water to extinguish it during a long, and very hot burning fire. This cracked and eroded the cement in the firebox quite badly. I removed all the loose pieces down to the metal mesh, filled the craters back in with this cement, let it dry and then followed the curing instructions to the letter. It cracked during drying before curing a bit, but the cracks appeared superficial. Over 6 months since then, it has helped up pretty well though it is breaking apart a bit in some areas and some pieces are coming loose. Overall, the firebox is still in much better condition than it was before I performed the repair, so there is that. After this winter season is over, I'll chip away any loose pieces and apply another layer - which I suspect won't need to be anywhere as substantial as the original repair I made. I do really like that this product was VERY easy to apply and work and it adhered extremely well to the existing masonry of the fireplace even while working. I did mist the existing masonry with clean water to dampen it before applying which probably helped. All in all, I would buy this product again.
