Why damp proofing internally will NOT work

paint flaked off because of damp in walls

Anti damp paint for damp walls usually comes in the form of an internal blocking or barrier paint but is it effective?

Never paint again says “NO” and tells you why you could be throwing good money after bad.

Never Paint Again has been at the forefront of controlling and curing all kinds of damp in houses with our special damp proof paints and anti damp wall coatings since the 1980’s and we have a range of damp proofing solutions to help you if your home has damp walls.”

Now there’s a statement that is right to the point, do we know what we are talking about?

OK, I’m biased writing this so i’m gonna say Yes anyway, but time after time we visit houses where there is a damp problems, and the owners, or some cowboy builder, has tried to cure damp internally in the hope that it will go away.

Masonry paint does NOT cure damp!

Damp, remember, comes from OUTSIDE, so if you have placed a barrier in the form of anti damp paint on the walls inside, the damp IS STILL THERE, IN YOUR WALLS, JUST BENEATH THE BARRIER YOU PAINTED ON!

And whilst it is in your walls, and not going anywhere, it is getting worse.

The damp in your walls ….

  • Rusting your wall ties, which long term can cause the outer leaf of the house to collapse.
  • Causing wooden joists and boards, including wooden lintels on old homes, to ROT.
  • Collecting in the tiny holes and gaps in the bricks, which when the winter comes, will freeze and expand, causing myriad fissure cracks throughout the entire structure of the house, possibly leading eventually to dilapidation.

Sorry to scare you, but please, if you don’t believe me, run the above points through a qualified, chartered surveyor, a member of RICS or some other organisation and they will agree with me!

There is a variety of damp proof paints available on the market today: Some damp proof paints are suitable for the semi competent DIY fanatic, almost exclusively mostly interior paint, and can be used safely, according to the paint manufacturers instructions.

But they will NOT stop the damp in your home.

Damp proof wall coatings

Specialist damp proof paint or anti damp wall coatings are mainly used by wall coatings companies and contain a mix of resins and chemicals that can only safely be used by someone who has the correct tools and training to apply them.

The Anti damp paints Never Paint Again use are the UK’s top exterior masonry coating company.

They are applied by a special spray machine after extensive cleaning and repairing of the outside walls, typical repairs include pebbledash replacement,  re-rendering, brickwork joint pointing, removing and replacing cracked pebbledash, fixing hollow (blown) render, and a whole host of other tasks to make the house exterior walls solid and fit for purpose.

After the preparation, our teams spray apply a flexible external wall coating which has many benefits in addition to stopping damp coming through the walls into your house. The wall coatings is self cleaning, does not fade, crack, chip or peel and is guaranteed for 20 years!

Other damp proofing methods, but without paint

If you want to damp proof the walls of the house but do NOT want to add a waterproof paint-type coating then there are other options at your disposal, one of them being our clear coat system.

The system is sprayed on, and the capillary retraction, the soaking up like a sponge that a damp wall has, soaks up the chemical instead, crystallising inside the wall, not outside, and stops damp getting in.

So as you can see by now, trying to stop damp by attacking it from the inside, clearly will NOT work because the damp will just find another part of the wall to come through.

The ONLY way to cure damp is to have work done on the EXTERIOR of the house!
