I am really new and not sure what I am doing to be honest.
I am laying down a t&G subfloor over ceramic tiles to protect them(I am leasing a store front, owners would like to keep the tiles there). This is my first time doing this so I was wondering if someone had some good first timers' advice for me, what to look out for, what not to do, etc.
I will be screwing the sheets to together and not using glue (the idea is in case I need to replace a single piece down the road). I have a chalk line, circular saw, drill and various other tools. Do I need a sledgehammer?
