Open official sourceWhat these sources do — and do not — mean
A standards reference does not prove the cause of a specific damp patch. Membrain still separates observation, mechanism and evidence before recommending a path. Product-specific application details remain governed by the current approved manufacturer technical data sheet for the product actually selected.
