AP Smartcare Damp Sheath Interior

An acrylic co-polymer waterproofing primer for interior walls with a damp problem: the classic Old Delhi shared-wall situation where the neighbour's bathroom is on the other side and your paint keeps blistering. It stops surface dampness working through and ruining the topcoat, and carries a waterproofing warranty when applied to the specified system. Ask us for the current terms.

Understand its limits. This treats the symptom on your side of the wall. It will not stop water arriving, and against serious rising damp or a live leak it will fail like anything else. Find and fix the source, then use this to protect the finish. Applied over fresh or existing putty, then primer and topcoat as normal.
