Discuss Advice on prep for stone patio in the Australia area at TilersForums. The USA and UK Tiling Forum (Also now Aus, Canada, ROI, and more)
I'm soon to be laying some classic grey limestone random lengths in my garden . Just wondering on the best prep for it? It's currently just grass at the moment. Area to be tiled is approx 30sqm. I've never done any external tiling before so I was thinking of laying a concrete slab then tiling when the screed is completely dry? What's the best way about it? Cheers ollie
hi yes a good thick concrete slab first then just as you said wait till dry then SBR it ,use 1 part flex add flex grout happy days
That's great cheers. Would you use ditra or something similar?
I'd be putting a ditra down with the stone, there's more chance of an external concrete slab cracking...
Crack suppression
Waterproofing
Vapour barrier
Load baring qualities
Quite a few benefits to ditra in this scenario
You don't need a concrete base if you dig it out and use type one .wack it down with a wacker plate and you can then fit the stone on a mortar bed
I. With gary, it's. Tad daft putting a waterproof membrane on a external patio, they need drainage
