Can I tile over a cement patio slab? Winter get to 30 below here.

I have a cracked cement patio slab. Still seems flat. Years ago we had a finish put on it (like they do on garage floors) that flakes off around the crack. What can I do to cover up this that is a permanent solution? Wondering if I can tile it with possibly slate, build a composite deck over the top of it, etc. Any ideas?

    I would recommend boulding a deck on top of it providing the slab is stable

    that crack is 'always' going to be a problem, though the new acrylic-enhanced patch repair (the sort for a caulking gun) may well slow it down for years.

    whether or not skim coating or tiling will work depends to some degree on if the 'finish' is worn enough not to keep the new layer from bonding.

    building a deck over it? sure - much work, but big payoff.

    patching the crack, and using a 'sponge' roller to repaint the slab (mottled colors will hide the texture changes better than a solid coat) would be the least work, how well it holds depends more on how damp than how cold it gets out there.

    concrete cracks because of ground shifting or tree roots under it too. If its cracked I would think not wise until you find the real reason and repair the crack. Concrete also expands and absorbs moisture. I would talk to someone in this field before attempting to do this on your own...

    Why not try getting some recycled rubber pavers and lay down on top of your cement slabs. They have them at HD and Lowes. I have the recycled rubber borders around my flower bed and have had no problem with them at all.
