Tiling over a garden deck?

hedger

My wooden garden decking needs re-stained every year and is looking very tatty even tho its only been down 2 years. I was thinking of tiling over it. What tiles are suitable for outdoor use (porcelain/slate)? Can I tile straight onto the deck?

Hello hedger

I'll move your thread to the 'In my home' board.

Hi, Martin’s asked me to post this in these circumstances: I’ve asked Board Guides to move threads if they’ll receive a better response elsewhere(please see this rule) so this post/thread has been moved to another board, where it should get more replies.

I wouldn't. Justification for this is that you would need to board over your decking, you could probably use marine ply, but I don't know what would happen to this with continued exposure to moisture. Theoretically you can tile over, but you would need to find an alternative to plywood that is going to weather, if this is cheaper than removing your decking do that, but I would imagine it would be easier to take up all the decking and pour a concrete base, costs could be comparable though.......

Couldn't you sand it down and then invest in some decent decking stain that is "guaranteed" for 5 years like cuprinol or ronseal etc....? Might be the cheapest and most hassle free option.

Hi

I agree with Adaze, as you are tiling onto wooden decking its the nature of wood to move in various weather conditions, either marine plywood it of use a decoupling membrane such as Ditra matting from Schluter or CI matting from Dural, both are made from a PVC base and can be used as they will allow the wood to more and not pass that horizontal movement on to the tiles.

Good Luck!
