I am going to install new tile in the kitchen and master bathroom. I have taken up the tile that already existed and 98% of the adhesive..what remains is very little and just enough to make the floor not a smooth surface but rather just a little rough in some places - I would estimate about 1/8" tall in those places. Is this a big deal? do I have to make sure it's 100% clear of any of this old adhesive?
Thanks!
Thanks!
