Concrete deck flooring

Tags: Miscellaneous

I have an above-grade 16'x16' concrete deck in the back that has a "rough poured" texture (ie, not smooth). I'm not a big fan of this type of surface and I'd prefer to have conventional 1"x6" wood decking to walk on. The deck is open to the sky and I'd eventually like to put a sheet-tin roof over it.

But for now, the flooring: what I'm thinking of doing is fastening a series of pressure-treated 2x4 "joists" to the concrete deck surface and nailing the 1x6 treated wood decking. The concrete surface has a slight slope away from the house so water will not "pool" under the 2x4's, although they may remain damp for a few days after a rain. I don't know if this will be a problem, or if there is something else I could do for the "joists".

There would also need to be provision made for the posts of the deck rails and the posts for the metal roof.

Am I on the right track?

Thanks,

Have you looked into plastic lumber (recycled plastic & sawdust) for joists? More money but won't rot. Pressure treated wood rots slower but still rots, especially if wet. I would attach the rail posts to the concrete, at least the base, before laying the deck. The posts can stick through the decking.

Hmmm, I hadn't thought of using "plastic" lumber. I'll check into that. I don't think it's going to be an extremely wet or rot-prone arrangement, but it doesn't hurt to plan around a potential problem

I was thinking about attaching the mounting post bases to the concrete and building the deck around them.

Thanks,
