Porcelain Tiling My Garage
Hi everyone,
After reading slickgt1 and Jack's garage and how great the tiles have been working out for them. I decided to start planning to lay some porcelain tiles in my own 16' x 20' garage of my house that I bought a year and a half ago.
My concrete floor has been neglected by the previous owner(s). It is a 1971 house and I believe the garage floor has the same age (it's an attached garage). So it has its own problems.
PROBLEMS:
1- The concrete has been crumbling. Some spots feel hollow when knocked on and when I hit the spot hard with a chisel, a 5mm layer of concrete comes off (see pics). What's underneath seems pretty solid though.
2- There are also some cracks that have been filled previously with some repair cement that are starting to crack again (see pic).
3- There are also some less traffic frequent spots with a layer of some old paint (see pics)...
I need your precious advice on what I need to do prior to tiling it with porcelain tiles. Here are my questions:
QUESTIONS:
4- First of all, my floor is slightly slopped through the center of the garage (where the drain is - see pic). Will this be a problem for tiling?
5- Do I need to chip off all the hollow spots before tiling? My guess is yes, so the thinset grabs on something solid
6- Do I need to use a densifier prior to tiling?
7- What should I do about the cracks? Dig out the repair cement and fill with some more appropriate crack fillers (like some epoxy based stuff)?
8- Should I grind off the paint first so the thinset adheres better?
Thank you for your advices.
