Building a decorative deck on a concrete slab balcony

My current project home has an approx 1m x 2m (3x6ft) concrete slab balcony. I've removed the old, ugly and chipped tiles, the slab is in great condition, and I'm thinking of basically cladding the top with timber slats - basically an ultra-low deck on top of concrete. I'm going to paint the slab first for aesthetic reasons, lay down some 1cm (1/2 inch) high 'joists' to let my slats drain. Total height so far will about about the same as the previous tile and adhesive, so it will all fit. My question is, what can I do to keep these 'joists' dry? Should I lay the whole thing on top of a plastic mesh so water can drain? Would it be better to use some plastic composite slats for my 'joists' instead? I don't want to raise the height of the deck much more if I can avoid it, I've got maybe a 1/2 cm (1/4 inch) to play with. I'm not worried about the deck slipping around on top of plastic, it'll be easy enough to anchor it securely to the concrete slab. submitted by /u/RenovationDIY [link] [comments]
