[sccpartners] Slate Floor
I stripped a Slate floor about 2
years ago. Shortly afterwards a few spots showed up in the center of a
few stones. You could wipe them off but they would come back. I
tested the Slate for moisture with a moisture meter, no moisture. 2 years
later we went back and cleaned the black Slate and sealed it with an
impregnator sealer. The Slate is inside of the home. Approximately
2 weeks later more of these dark spots showed up. No moisture. The
floor is about 40 years old and had a wax coating on it for about 35 years that
we removed. Any ideas?
Thanks
