Some background info: My exterior back patio tile installed over concrete is old, cracking, and in need of replacement. The tiled area is fairly large measuring about 20ft x 10ft. I live in Colorado so we get a fair amount of snow and cold weather. After snow/ice the tiles are extremely slippery and pose a fall risk.

I’m trying to come up with the cheapest solution to replacing the tiles that also reduces the slippery-ness?

I was looking into installing waterproof, nonslip, rubber flooring on top of the existing tiles. Is this feasible?

If not, I can remove the tiles but definitely want to stay away from removing any thinset below. Can I install something like this on top of existing old thinset?

Won't the rubber get covered in snow and ice thus becoming slippery? Deicing compound is your friend.

you are probably right. will definitely use deicing compound but still want to do something about the deteriorating tiles

I’m just gonna guess, you should check manufacturers recommendations, but I doubt the rubber flooring is meant to survive the elements. Between UV and freeze/thaw cycles many rubber products will fall apart when left outside. I also don’t think rubber flooring will remain “nonslip” when covered with snow and ice.

Is the cracking just the tiles or the concrete below? If the concrete is solid, I would thing that filling in / securing any cracks and installing on top would be ok.

concrete is solid from what I can see. sorry i’m a total beginner to diy, what would i use to fill in the gaps between thinset before installing on top? more thinset?

A concrete patch premix would probably work well. All the big box stores have something like that. You just want it nice, even and secure.
