Damp Seal Paint - Use Everywhere?

[pastafreak]

When using this,is it necessary to use it on all surfaces in a room-or can it be used only where there are damp patches or mould?
I used it a few months ago in my bedroom-on every wall and the ceiling-as that room was the worst affected. It was a rather expensive job...:-(

If you don't need a waterproof membrane you don't need to use damp seal paint!

Just use it where you need it.

You really need to find the cause of the damp and not try to seal it in as this will only push it somewhere else. If it is mould then you need to kill it off with a mould and mildew remover first otherwise it will continue to grow under the paint and push the paint off the walls then just paint with normal emulsions. If it is somewhere like a bathroom then use a proper bathroom emulsion as this will help stop the mould forming again.

The lads are right, Pasty. It's condensation. It would be best to find the causes and ventilate more if you can.

Good morning...I did treat the areas with a mould and mildew remover-which I will do again with these smaller areas.
I do ventilate,and keep the rooms warm in cold weather. This problem has been discussed with building management. I live in a block of 60's built 2-storey maisonettes...and we all have major problems. Interior walls are always cold. Cavity wall insulation was installed several years ago-it has made little or no difference-and management just says "ventilate".
In other rooms the problem is confined to upper corners near the ceiling.

Blimey! I had to use this in my old house, as it was an old victorian place and had a couple of damp areas in one of the rooms, and even just the one pot was expensive.
It's also quite difficult to apply, as it's much thicker and "gloopier" than normal paint, so hats off to you for doing the whole room! I painted just the areas that had the mould spots coming through, after using a mould and mildew remover on it. Did the job just fine :-)

Maybe the answer is to replace the walls with something more modern ;-)

(None of this thermo block type nonsense though. You need the things screwed into the wall to stop there.)

My daughter helped-it took us 2 1/2 days to do it....treat the walls,damp seal...then emulsion. Took me another 3 days to recover!

@ Old_Geezer...do you mean dry lining(I think that's what it's called)...expensive-right?

pastafreak lives in a block of 60s maisonettes like do and ours are flat roofed too they cannot be insulated because of their deign and the owners of these buildings wouldn't anyway , and yes i know all about ventilation and de-humidifiers but i get this in corners of kitchen / bathroom i have to go round with mould remover twice a week, in winter months,so i would give the dam-proof paint ago but only where necessary
