Best Answer

In warm and well ventilated drying conditions allow 1 day per millimetre up to 40mm in thickness, so 40 days if 40mm. Thicker substrates require 2 days per mm.

Use reputable flexible adhesive for tiling on screeds and concrete and as per the manufacturers specifications, DO NOT USE PVA but a latex based primer if the concrete surface is shedding dusty, fine particles after drying.

Hi Emlyn,i would recommend you leave it at least 28 days,as you need to allow all the moisture to escape.Otherwise when you tile it will trap the moisture in,resulting with your tiles lifting.
Thanks Steve.

Usually 48 hours depending on how deep it goes. Dont forget to seal the floor with PVA before applying any tile adhesive and use a good quality adhesive for your tiles.

Concrete takes aong Time to dry fully out depending on the thickness usually you should be able to tile after a few weeks.
