Anti-crack matting?? Why? - TilersForums.com

[nis999]

I’m about to tile a small bathroom floor with 20cm porcelain tiles on a very solid floor overlaid with 12mm WBP using Mapei Keraquick with latex. I’ve used this before and 10 years on still good, no cracks etc. But the local tile supplier says I should use anti-crack matting. I always thought you should over-ply to eliminate movement, yet what he showed me would appear to allow movement??? Am I missing something here and why is he saying this is necessary? I’d be grateful if someone could explain the tech aspects and exactly how this works?

Idk for sure, but I am reading this article about it.

are they suggesting anti crack matting over the substrate, or on top of the over plyed floor?

Over the ply... but I spoke with Mapei technical and they said Keraflex would be fine directly onto the ply, so thats what we've gone with.
