Just add color and non-slip texture in one step! Buy the color you like and add non-slip texturizer to the paint! It works well in cold weather. I'd be tempted to do a marbled effect; much more elegant for a patio.

HI -- Lets call the guy that did this a ... numb skull .. he just rushed the job to get the money . Inquire around to pool companies to see what kind of finishes they could recommend for a non - slip solution . You could probably search pool surround finishes right here on Houzz . I think there is a kind of rubberized finish that is spayed on but not sure . Good Luck .

Hello BJ,

You can apply a stain to the concrete for a natural look. Sometimes we will grind the surface to expose some of the aggregate and then apply the stain or finish with a clear coating. You can use a product like http://www.deckoseal.com/02/07/deck-o-seal-polysulfide-based-joint-sealant/ to dress up the expansion joints.

Tile is definitely an option also. Just be sure to select a frost proof tile, like a brick paver, porcelain tile, or a denser natural stone. If you choose tile, you should install an expansion joint directly over the wood joints similar to http://www.schluter.com/4_7_dilex_bws.aspx .

Assuming you choose tile, concerning the deck drain, you will have to either buy another drain assemble and stack the base on top (extend) of the existing or perhaps have and extension custom made at a sheet metal shop.

No matter which option you choose, you will need to remove the hand rail and reset when your finished.

I hope this helps!

Another alternative would be to lay 3/4" thick porcelain pavers 24" x 24" over the top of the existing concrete as these can be lifted off the ground a very small amount by using 5/8"or 3/8" thick rubber support pads situated under each corner of the paver. Because of their thickness they are rated as a structural paver but being porcelain they also have the advantage that they are completely freeze/thaw resistant so would be quite suitable for your location.

Porcelain pavers also have a textured finish to make them slip resistant so would be suitable for use around swimming pools.
