How long before tiling?

[stevedo]

I've put a thin (approx 2mm) coat of plaster on the walls in an en-suite shower room over the weekend. This morning the plaster appears to be dry, no "dark" patches. Typically how long do you guys leave a freshly plastered wall prior to tiling to ensure good adhesion?

Thanks

Should be 4 weeks however due to the thin coat 2 should be ok. It is not just about the drying it is also the increase in bond strength of the plaster over time.

Ah.
So the guys who skimmed my bathroom on Tuesday and tiled on Wednesday were a bit quick then? That was a couple of years ago and nothing has fallen off - yet.

Thanks Ty,

I used Unibond PVA in 5:1 Water/PVA as a sealer first and then a 3:1 PVA/water and plastered whilst this was still tacky so hopefully bond strength will be good.

give it another coat of pva 5-1 to kill any suction and away you go.

Will do. Thanks for the advice.
