This summer I tiled an existing outdoor patio with porcelain tile and I was wondering if there is anything specific I need to do to winterize it other than sealing the grout? The tile was laid from edge to edge on top of the concrete but not on the sides of the slab. It is a small patio only 8" by 10". Thanks.

What did you lay your tile in, thinset?

Yes, we used thinset.
