Damp on wall - help getting rid of PLEASE


Postby howiet » Fri Nov 07, 2008 2:43 pm

I had a leak in my kitchen under the cabinets; this was slow and wasn't noticed for about a year; I only noticed it when a damp patch appeared above the tiles about 5 ft off the ground, and paint started flaking off. It as all done a year ago too... :(

I have had the leak fixed about 4 weeks ago, BUT, the damp is still getting worse. There is a line of wet wall, and below it flakey paint. The wall backs onto an old victorian out-door loo; whilst it's not exposed to the elements, is probably damp itself.

D you think the leak has caused the problem, or i need to damp proof the outdoor loo wall?

Unfortunately I am broke as broke can be right now and need todo the job as cheaply as possible. What is the best way? I've been reading about injecting the wall with some cream?

Thanks in advance.

as a follow up, i checked the out-door loo and it is dry inside and can't see much sign of damp.

if you have buildings insurance it may be worth making a claim for the damage
The masonary / floor will be soaked and will require proper dring out (this could take 3-4 weeks using blowers and dehumidification
The top surface 2mm or so will appear dry quiete quickly but the moisture is still there below the surface and will wick up any porus surface , it will then cause salting (a sort of chalky bloom on plastered surfaces )
SAt this stage the plaster should be removed (this will also speed up the drying process)
