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.

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.

Good luck with it.
