Had a 150mm concrete base laid for new conservatory 2 weeks ago.
It is, and will be exposed to the elements for a further 3 weeks approx until the glass goes in.
How long until I can lay tiles on it.? 3 Months? Say end of January?
Any observations?
Thanks
Don
Standard proceedure for painting a concrete floor is to tape a small sheet of clear plastic down, or lay down a rubber car mat. When you can't see any more condensation on the sheet/mat its dry enough. Guess this also applies to tiling.
whenever you feel like it really.
After 4-6weeks it will be full strength anyway, and then tile away.
Its probably more important that its fairly dry.. so leave it a few days after the glazing goes in and tile tile tile.
to be honest, I mustt have added about a gallon of water per square meter in the tile cement when I laid mind, very thick bedded over a very uneven screed.
I don't think dampness is an issue at all with tiling. It will eventually dry out via the grout anyway, and slow drying is fine.

A week per inch is a reasonable rule of thumb. I'd give it a couple of weeks after the glass goes in or until it looks reasonably dry. It will certainly have had a pretty decent cure by then so it should be stable and pretty much as solid as it's likely to get.

Thread high jack alert!
Does *dry mix* screed need to be sealed before ceramic tiling?

No.
Sealing is for painting, although paint itself will seal, and to stop dust when the layer above is floating. Or before e.g. doing self levelling, to slow rate of water absorption.
With a decent tile cement, you effectively get a BIT of suck from the screed, but really not that much.

OK So, seal under the engineered wood bit and ignore the tiled patch.
Ta.

yeah, basically. Worked for me anyway.
