Worked well for beginner rustic mosaic bricks
Let me start by saying this is my first time making mosaic bricks/stones. I used this mortar for the grout between the tiles, which I’m sure was exactly the wrong way to do it, but I did it anyway and it worked…

Not a true thinset but works
I’ve done floors for years and always referred to thinset as a mix that has no sand or such fine sand you can’t tell when you trowel it out. This stuff has a pretty coarse grit to it. Otherwise, it worked well…

You can see in the background the mortar mix. Keep it the right consistency and it works extremely well. I filled 75% of the fire place floor fire bricks. It filled well and looked good.

For some reason this last bucket of refractory mortar is drying within 10 minutes and is looking fully cured in about an hour. Very very hard to work with. I have purchased a lot of these in the past and none of them have set this fast. I seems like it has accelerant in it. I’m going to need another 25lb to finish my pizza oven. I hope the next batch is like the ones before this one.
