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: Excellent value, - Sets up quick, I found the work time to be about 20 minutes, so I made up small batches for a Stone Age Fireplace that I am building. It seems to be a very good product, especially for the price.
