i have two different situations with my wood floors. the floor in the bathroom has a damage spot where the floor has a hold from the water around the tub leaking onto the floor. i need to know how to remove that spot. do i just put a piece of plywood over it or cut it out and replace it? secondly i am in the process of wanting to retile my livingroom area. i already have self adhesive floor tile down and don't want to go through the trouble of taking each one up. will it be easier if i subfloor and then retile with leinolium or just retile directly over the existing tile? i want a look that i will be proud of once i'm finish.
