How do you repair a concrete patio?

I have a rather large - 16 x 24 maybe - concrete patio. It used to be used as a carport. The surface is cracked and one corner is a little lower than the footing. I can't deck over it because of a doorway and yard entry gate. I thought about resurfacing or putting slate or rubber matting tiles over it. Any suggestions?

There is a product you can apply as a "topcoat" . I don't know what it is called. I'm sure you can find it at Home Depot or Lowe's. It is applied very thick. This is not the garage paint stuff. I haven't used it, but am thinking about it when I get ready to work on my patio.

Sakcrete Top n'Bond concrete patcher or Premixed concrete patch. You can get it at Home depot. I have the same problem.

Ditto with the Sakrete, they also have video's to show you how to use it on their website.

If the patio is still moving, the cracks opening and closing, using a resurfacer (topcoat or skinning over the patio) will suffer the same fate regardless of the product. Topcoating simply doesn't have the strength to bind the existing patio and prevent it from moving. I've seen slate used in situations like this but it's success would also depend on the amount of movement. Slight movement would cause any grout to crack out and large amounts could cause entire tiles to crack or pop. Since adding a concrete resurfacer is going to add a minimum of 1-2 inches in height to the patio, you might look into decking directly on top the concrete patio anchoring the deck boards directly to the patio. You would have to adequately space between the 1 1/4 inch treated deck lumber and provide an unobstructed path so water could drain. If patio is sloped properly it can be done.

Patch, fill, and then just stain it. Lots of instructional videos online.

You may need to have the sunken portion slab-jacked back to grade. Then proceed with surface prep (pressure wash) then using concrete adhesive apply top-coating material of choice. Personally I would not install deck boards or anything else until the area is resurfaced and proven viable for the local conditions. Long-term maintenance considerations should be a priority in planning the project.
