Lets try to end the guessing and assumptions being thrown around re this miraculous product.
Pecilastic is an uncoupling membrane for use under tiles over substrates susceptible to lateral tensions. A thin membrane consisting of 2 layers the upper and lower separating under tension.
Pecilastic can be used over weyroc chipboard floors as an uncoupling providing the floor is of “good quality, fully braced chipboard”
Fully braced chipboard means the chipboard should be fixed at 300mm centres in both directions. For those unclear on this, joists must be fixed too every 300mm and noggins must be inserted between joists at 300mm centres.
Failing the above the floor should be stabilised by over boarding.
Pecilastic is NOT a replacement for ply unless the floor is FULLY BRACED
As Pecilastic has no core it does NOT function as a waterproof membrane.
Here endeth the lesson kindly provided by BASF technical.
Personally I think the phrase “good quality, fully braced chipboard” is the important one here as it surgests far more than it says !
