been a while since I've been on - bought new house and couldn't think of any diy projects that I needed help with till now. thinking of laying tile in my garage instead of epoxy or other garage flooring. Good or bad idea? if I go thru with it how do I handle expansion joints? What prep work for 4 yr old concrete? So I lay down a membrane? Thanks for all advise
Good or bad idea? Probably a little of both.
Pros: It will look great and really upgrade the garage. Less dust and easier to clean than raw concrete.
Cons: It is going to crack. Just hairline cracks but not too much you can do about it. If may also be slippery - depending on what tile you get. Finally, some garages go through a lot of abuse. It's one thing to spill some paint on your concrete floor. Quite another if you do it on tile.
You should be able to lay tile in thinset directly on the slab. Clean the slab with a mild muratic acid or any of the first-step cleaners used for epoxy floor paint kits. I would try to line up expansion joints with grout lines, but really wouldn't worry about it too much (see the above "it's going to crack" comment).
thanks Jaybee and sorry for the delayed reply. Should I expect more hairline cracks then the tile inside that was laid on the homes concrete slab? If so why?
Take a look for any hairline cracks that you can find in the slab - odds are those cracks will continue through the tile. You could isolate some of this movement by installing a Kerdi liner first, but that will get expensive since a garage is a large area.
Generally you can expect more cracks in a garage than on the interior slab, although both should be fairly close. The garage has the added stress of heavy vehicles plus wider temperature changes over the seasons. Both of these can cause more cracks. Overall, it's more important how the slab was built - density of soil underneath, use of rebar or wire, concrete mix quality and temperature / humidity at the time of the pour - all will affect the final product.
i tiled my back porch in texas...was told to use a outdoor tile adhesive...so the concrete could move and not crack the tile.due to weather.so i did
