Excellent website, I've used it for years but first time I consider I need your direct help.
I'm creating a raised patio at the rear of my house around 28 sq m. Retaining wall built. A base of broken tiles and smashed bricks laid down followed by 75mm of MOT Type 1 that I still need to bring the level up on and compact.
I hope to use porcelain tiles 20mm thick that I had assumed I could lay on a mortar bed. Imagine my shock to read on your website and elsewhere that it's not straight forward due to the low absorbance of porcelain.
I don't really want to paint a slurry mix on the backs due to the risk of making a mess of the tiles. The type 1 is laid so it's too late to opt for a concrete base and tile adhesive. The only other option I can see is to use pedestals. I like the idea (not so much the cost) but would it be suitable to put them directly on type 1? Something tells me this is a bad idea. Does anyone have experience of doing this on anything other than a concrete base?
Just a final thought on that, my type 1 is at wall height so pedestals on that will raise the tiles up around 20mm leaving a void at the edge where they overhang the wall. I guess I'd have to put some kind of mortar under that part of the tile.
Thanks in advance
