I have the block laid for my fireplace, so I plan to start laying brick in the firebox and on the exterior this weekend. I figured I'd go to my 2 go to places for refractory mortar. One is a stone supplier, the other is a place that cleans chimneys, builds fireplaces, sells woodburners etc. Anyway the stone place only had fire clay to roll my own, so I called the chimney place. They had 3-50# bags of refractory with some other items in the box someone ordered and never picked up. I went and checked it out, and it was castable refractory cement with what looked like 12"square FB (type) board. They said I could have that also with the cost of refractory cement. I explained it wouldn't work and I needed mortar. They looked at me crosseyed! I asked if they could get HeatStop products. "Never heard of 'em" As they were looking thru the catalogue, the mgr looked at me perplexed and asked "what are trying to do!?" I explained I am building an outdoor fireplace. She exclaimed "Why don't you just use Type S, like we do!?" I told her I wasn't comfortable with that, especially for the oven. Then she asked what about the the stuff in the pail below. It stated right on it that it was not for exterior use, as it was a pre-mix and water soluable. Anyway, I'm out right now. I think I'm going to use S for the fire box, and I found a place that has the refractory mortar, dry, in 10 or 15# pails, but it's not cheap.
No announcement yet.
Anyone else find this amusing?
