## Customer Reviews

### ⭐⭐⭐⭐⭐ Nice Product at a Good price !
*by E***K on July 11, 2025*

Nice refractory motar at a good price!! Only thing I caution against is using it on a very hot & humid day. I do understand that the directions caution you against using it in that type of weather and does not recommend it, but we gave it a shot anyways cuz we were kinda on a time frame to get a specific job done. It ended up working out pretty well, but I recommend if you do like we did and use this product in the hot weather, that you keep the hose or a bucket of water close by to prevent motar setting up to quickly!! We learned quickly to keep adding a little bit of water and it keeps the motar smooth & workable. This mortar will definitely set up quickly in the heat.Functionality:Works very well & easy to use when mixed well and kept moist.

### ⭐⭐⭐⭐⭐ Great product
*by D***D on March 22, 2025*

1. The bucket opens like just about any 5 gallon paint bucket. So ignore every review complaining about it. 2. Most refractory mortars are grey and I needed to color this to match the beige brick on a project so I really appreciate being able to purchase a larger quantity of white mortar for a reasonable price. 3. The mortar works great and mixes up like any other professional grade refractory mortar.In summary: if you need a light colored refractory mortar this is a good one.

### ⭐⭐⭐⭐⭐ Relined my prefab fireplace
*by J***H on January 18, 2025*

Use this product in conjunction with fire bricks I’ll purchase from Amazon and saved over $2100 on having someone do the job. I did it myself minimal time and had excellent outcome.
