I am in the middle of redoing my basement, new drywall walls. ceiling and electrical, the house was built in 1955 and the finish basement was done around 1970's, the floor has 9"x9" tiles. The first time i just put wall to wall carpet over the tiles. This time I am going to put a new carpet down and i was told i should skim coat over the existing tiles then add felt then carpet. I have no idea what to use for skim coating. i have three room about 13'x 13'. i was thinking of adding wood floor for my office and the rest of the rooms wall to wall carpet. Is this a easy project to skim coat over the existing tiles?
