Review: Nice Product at a Good price ! - 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.
Review: Easy To Work With For Do It Yourselfers - Just open and stir. Great Product!

Worked better than expected. Mixed with the exact amount of water and the mortar laid smoothly. Have not yet built a fire so not sure how it will hold up, but seemed to have cured well.
