anyone use this for tiling onto?

Obviously lightweight tiles only as per most other plaster finishes. It seems crazy to do a float and set on some walls when a one coat system would work fine.

I trowelled a wall with it yesterday after I did my homework. I’ve previously not used it as a prep for tiling because i’ve Never considered it suitable.

Never. If "plastering" is needed, I will either re-board or patch up with sand and cement render.
No gypsum on my walls ever, if I have my way.
Occasionally I have to tile onto pinked walls, but then it's ceramics or thin porcelain only and I moan like mad about it!

The tiles I’m using are small ceramics. I don’t get that many occasions where I’d have to plaster but this is one of them. Not enough space to re board. Not enough space for a two coat system really. Definitely not enough for a S&C render so one coat it is. I didn’t want to come out any more than about 10mm

I’m a big re-boarder and do it on most jobs.

This is what I had. Plaster was rock solid. A couple of holes to fill from integrated soap dishes.

One coat was the answer. Knocking the old plaster off and a two coat system wasn’t an option IMO.

Noooo. That wall was the one I one coated. That’s what the thread is about- me not knowing you can tile onto one coat. It’s got a tough finish to it. As usual with plaster, I lightly brush before final troweling, same with Multifinsih. Not a bad surface to tile with small ceramics IMHO.

That was an option but the wall was too far out. The wall with the shower valve on has a door on it and I’m fighting to get a tray in. Tray is 1500 x 760. Already I’m having to chase the long wall out slightly.

Overall, one coat was my best option. It’s completly flat and Plumb now. Trust me, dot and dabbing was my first thought.

A serrated trowel and HB would’ve worked depth wise but the wall would be p1ssed.
