Tiling over new plaster

[Nodge]

I've just removed the old tiles in my bathroom and made good with Wickes Universal Plaster. Can I just tile over this as soon as it looks dry (one or two days perhaps) or do I have to wait weeks?

The tile adhesive I last used required walls/plaster to be completely dried out before use. There are probably some that don't, because I doubt most builders would wait that long. If you just reskimmed, a few days after it looks dry (gone back to light colour if pink plaster) would probably be good enough, but if it was a new brick wall and fully plastered, it takes much longer to dry out.

It takes about 3 days to dry it unaided in summer with good ventilation for painting. I've no idea what the requirements are for tiling. How does the water from the tile adhesive get out I wonder?

I think the theory goes that it escapes through the gaps you leave between them in the 24 hours you leave it before grouting...

I have just put down 200 tiles in the bathroom including 100 fancy itsy bitsy sandblasted glass jobbies that SWIMBO fancied... I hate tiling. Still, it does look infinitely better than the mouldy stained wood panels we had in before! Now to finish off the grouting )-:
