My newish-to-me house has a Florida room with a cement floor. It's
painted and can be a bit slick, especially for my dogs with fuzzy feet.
The patio is the same level with the cement outside of the expanse of
sliding patio doors (maybe even the same, just with the track across
it). During hard rains, I get small puddles just inside of the tracks,
which is the subject of another question sometime. The problem, though,
is that I really don't want to put down decent carpeting for traction
until that's resolved. I haven't slipped, but I am a bit concerned that
it could be slick if wet and I have guests.

Any suggestions on how to treat the floor? Deck paint? That speckled
stuff I've seen for garages?
