Hi Sally , I would strip of old plaster and apply a membrane barrier to internal walls , basically a plastic barrier , the walls can then be dry lined , and plastered straight away , then the outside render can be treated when weather permits, The membrane barrier is fixed to the walls with plastic plugs , you will not get anymore dampness , this is the current up to date fix for your problem, thanks Stephen
The room needs to be tanked with a slurry coat to create a barrier between the plaster and the brickwork i use Sika products you can find these on a google search. If the wall is dry lined the plasterboards will be soaking wet all the time because the walls wont be able to breath and youll have mould growing on the plaster and youll be knocking it all off again in 6 months time. If you use the damp proofing system I suggest and it is done properly to manufacturers instructions you should be ok
You would be wasting your money Sally. What the builder is recommending sounds like temporary quick fix. If I were you I would get a damp proof specialist out to your property ASAP and discuss the correct way to resolve your situation.
Hi Sally the proper way is to remove the plaster and put in place a dehumidifier to assist in the drying out,Dry lining is just covering the problem. Regards and good luck Graeme
Hi Sally without visiting your property it sounds as though you need a damp proof membrane fitted. I would ask a rated people damp specialist to carry out a free survey of your problem. regards tommy
Hi Sally,don't dry line the room you will just be wasting your money.We use a product called Thoroseal which is a slurry based tanking system.You remove the plaster apply the mix and then re-plaster.The manufacturer give a ten year guarantee and it is a good system.
I would not recommend this , you need to make the external problem your priority to stop continued ingress of water , then the interior wall .
It's a quick fix and may not even stick to the damp walls ideally you'd strip it fix the out side and let it dry out before plastering or dry lining if u go ahead with the dry lining on top of damp it will come through
hi sally if you care to ring me on at your convenience i will talk you through the options you may have regards david
Hi Sally Your builder incorrectly informed you. Observing the technology outside of work can be carried out . If dry weather - why not? If the part of the exterior walls have cracks , they should be sure to fill out, note the areas where they are necessary to open up a brick and block masonry. Check the gutter. There are many factors of damp . You should seek the advice of our site to the independent expert . If you do not, then the conduct of internal work does not make sense - the moisture will continue to go in yours wall ... I Repeat respecting the norms and rules of construction at this time of the season you can spend outside work. Regards Sergejs
