My parents are convinced that they need to sign away several thousands
of pounds on a treatment known as Protectacoat for a house which has
solid brick walls with pebbledashed render - this is at least 50-60
years old and now there is some penetrating damp.

Protectacoat apparently seals the existing render with some sort of
rubberised layer and claims to provide a waterproof barrier against
further ingress of rain. This sounds highly suspect to me.

It is highly suspect. The last lot I ripped off was not only harbouring
damp, but various colonies of insects. Worse than useless because water gets
behind it and can't get out.
Would probably work if the render was sound but, if that were the case, you
wouldn't need the treatment.



Looking at http://www.protectacoat.co.uk/ this looks like a render
system in any case which means they may actually remove render rather
than just covering it.
