How to cover up interior damp

Tools required

  • One Coat Damp Seal
  • Soapy Water
  • Synthetic Brush

Damp inside your home can leave unsightly stains that are difficult to treat and hide. If you’re not sure what type of damp you’ve got, we recommend that you watch our ‘how to find and fix your damp problems’ video.

Once you’ve fixed the cause of the problem, we’ll help you make the area look its best again. We recommend our One Coat Damp Seal which will permanently block damp, and let the moisture out so the problem doesn’t return.

You can apply it directly to damp walls and ceilings. It will leave a smooth white finish ready for decorating over. To see how it's done, simply follow our 3 step guide or watch our video ‘How to stop damp coming through your paintwork’

Step 1

Make sure you’ve resolved the issue that first caused the damp problem. Then you need to sort out the stain that’s been left behind. Give the area(s) a good clean and wipe down first, to get rid of any mouldy areas and dirt. We recommend using a soft cloth and soapy water. Repair any holes or cracks before you move on to step 2. It’s important to make sure the area is properly prepared so the paint can stick properly.

Step 2

Our One Coat Damp Seal can be applied directly to a damp surface, but dry it as much as you can before you start. Stir well before use (use something which can get right to the bottom of the tin). Put plenty of the seal on using a synthetic brush, making sure that the paint is spread further than the affected area so as to treat invisible problem areas.

Step 3

Once you’ve finished the first coat, that’s it. Just let it dry for 4 hours and then you can re-decorate. No-one will know it was even there.
