Do not ever use PVA as a primer for tiling. The only tiling adhesive I've ever seen that recommends PVA was unibond ready mixed addy, and that is only good for tiles max size about 150mm square.hennase wrote:Good morning I PVA'ed it then tiled it,
Nothing to do with water "re-activating" the PVA; The PVA stops the tile adhesive from bonding to whatever the substrate is by providing a "barrier" between the adhesive and the substrate.dewaltdisney wrote:As far as PVA'ing before tiling it really depends if the area is likely to get damp. Moisture can reactivate the PVA and loosen the bond
I do not entirely go along with the reactivated PVA theory
