Help ! We are looking for the best and cheapest solution for a damp problem ! We have stripped the plaster off and want to know what to paint on the wall to stop the damp coming back ! The house is only lived in two weeks a year. Is gloss paint first then normal paint the answer ?

You will need to know why you have the problem and prevent the damp getting into the wall.
Just painting something on the surface will not solve the problem, but only camouflage it for a while until the damp pushes the paint off the wall again..
If you can be more specific, I am sure someone will be able to give you the correct advice.

The problem was the roof ! The house now has a new one, but brown marks have come through when painted with normal paint ! Sorry should have said that bit ! Thanks

Not sure if you can get it in SPain, but PVA is what you need. It's stuff you paint on for example bathroom walls before painting to prevent peeling. It is waterproofing liquid.

We had a problem with mould when our house was unused over the winter and the windows, doors etc. were shut. After knocking a couple of holes through the exterior walls and putting those little plastic vents in, that you get from B&Q, with a little switch so that they can be shut in the summer and stop the dust coming in, we never had the problem again, as air could circulate.

PVA or unibond which is pretty much the same stuff will stop it coming through or asn oil vased paint.
For PVA go to Leroy Merlin and buy there own brand wood glue, it's around a euro a pot. Mix this with water. Around a capfull to a litre and then paint thisa onto the walls. Bleach will also kill any visable mold spores before the PVA.
If you have air con see if there is a dehumidifyer setting, lots of them have it. Run your air con is this mode with the windows shut which will help get the moisture out of the walls. Or alternatively open all the doors and windows and let the house air.
Funny enough I am fitting three vents for a couple in Mazarron Country Club tomorrow who have a problem with condensation.
If the house does not have them think about fitting ventilation, something that in the main in lacking in Spanish homes.

Once it's done, we found those dehumidifier boxes you can get from a supermarket or a Chinese shop worked really well. They contain a crystal which soaks up the water and ideal for when you are not there and airing the place out.

You can do the same thing by putting plates of salt around the property. Ventilation is still the way to go though for a long term solution. Mind you I would say that I'm a HVAC engineer and do this for a living in Spain

In a private exchange, I have established that the damp was caused by a leaky roof which has now been replaced.
Thus, it is a matter of removing the affected plaster, replacing it and then using, as suggested by Chris, a PVA sealer.
