How long does concrete need to cure before tile can be installed?
While this seems like a simple question, in fact many issues must be considered. We understand from the PCA (Portland Cement Association) and the ACI (American Concrete Institute) that many variables affect the length of time a slab needs to cure and the length of time during which curling can be expected. Some of the more common variables are: 1) Cement – water mix ratio 2) Cement – sand ratio 3) Particle size distribution 4) Presence of accelerators 5) Curing compounds 6) Environmental conditions 7) Location of vapor membrane 8) Exposure to water during curing You can see that it is not possible to definitively state how long the concrete should cure before tiling.
