The subject of sourcing fireclay seems to generate a lot of questions.
After I went to the trouble of sourcing it for laying my floor, I made a mess of a sand/fireclay/water mixture that I later scraped off my insulation board (and took some of the insulation with it). I then mixed the fireclay and sand together and used that dry to lay my floor. I ran out of fireclay, so I just used sand for the rest of it.
If one is going to use a wet leveling mix, I can understand that the fireclay makes for a sticky mix. But for dry leveling, is there really an advantage to mixing the sand with fireclay?
