damp coming through internal wall.

In the recent heavy rain I noticed that I have a couple of small damps spots on my newly plastered kitchen wall at around chest height. These dried out fairly quickly so it is not a major problem.

The outside wall is fairly sound and there is no obvious place that water could be getting in. My suspicion is that I have a slight leak in the roof and water is getting in the cavity then getting into the internal wall via a wall tie or something similar.

In the Spring I intend to do some repairs to the roof, which hopefully will solve the problem completely. In the meantime, I want to finish off the tiling in the kitchen. Can the group recommend the best way of sealing the internal wall to allow me to go ahead with the tiling now, as I don't want to wait until the spring to finish this.

Using a good make waterproof adhesive to stick the tiles should be enough. If the damp patch is loosening the plaster as well, then you'll need to sort the leak first, but if, as you say, the wall is drying out very quickly, then a good waterproof tile adhesive shouldn't have any difficulty keep the tiles on the wall.

Good luck with it.

finish

Thanks, as I am tiling over anyway, I have decided to drill a hole to investigate as the damp patch is only about 2 inches across. I will post my discovery.
