Removed Tile from Basement floor, can I use EpoxyFloor Paint
I recently removed some very old tile from my concrete basement floor and I would like to put an epoxy paint where the tile had been.
It looks like there is still some black mastic glue on the surface of the concrete, and I am not sure if i can apply the epoxy seal with it there. The glue no longer has any stick to it whatsoever.
Can someone please steer me in the right direction? Can i just put a bonding primer on it before applying the epoxy or do i need to remove the glue? If i need to remove the glue substance, what should i use??
