Damp & Mould

[theborg]

Good morning

We live in a REALLY old farm house which is cold and damp

We rent so I'm not about to do any major mending

One wall in our kitchen is very damp, mould growing and it came through the warmaline & paper that was there.
We've stripped it and were just going to re-do with the same method.

Is there any quick way to stop the mould coming back through the poly & paper?

I heard that putting tin foil over the patches might be a good idea

Cheers for any advice

Paul

tape a piece of clear plastic tightly to the wall. If water appears on the room side it is condensation, if on the wall side it is coming through the wall. You need to know the cause before you try to apply a cure.

If it is condensation, open the windows, take wet washing outside, and read //www.diynot.com/wiki/building:condensation_in_houses

That's a good tip that is.

I did the plastic test last month, it's deff damp coming in.

just need a quick fix until we move next year

so why is the wall wet?

leaking gutter or downpipe outside?

penetrating rain?

damp patch at about ground level due to absence of dampcourse?

you need to find the cause before choosing a cure

Our kitchen has always had damp

We've recently had central heating installed

Damp patches are approx 8 feet from the ground, poss penetrating rain
possibly lack of maintenance on the outside, lack of gutter, etc.

I am at the brink of a possible fix...

Thompsons Damp Seal

Then Warmaline polysterene

Two layers of lining paper, one horizontal & oen vertical

or am I barking upm the wrong tree?

Can't do exhaustive research as this would cost, and the owners don't seem to care.

if there is a gutter missing, does water run down this wall in heavy rain?

how difficult and expensive would it be to fit a new gutter?

trying to redecorate over a wet wall is doomed to failure

REALLY old farm houses usually don't have a damp course or cavities in the wall, so if it's not coming up the wall it's coming through the wall, it can also go up the wall on the out side and then go in the wall when it finds a good bridge.

Will your pocket stretch to this, Get some 2" X 1" tanalized timber and build a timber frame and stick brick layers damp course plastic to the side that's going against the wall. Attach the frame to the wall with screws and rawl plugs before you put the screw in fill the rawl plug with sealant.
If the walls are uneven as they some times are in old farm houses put wedges between the frame and the wall covering the contact face with the damp course plastic. Then put plaster board on top. It's close to tanking and will work.

Good luck

Hi
There is no gutter / water route from this side of the house

Basically, the walls are pretty porous, if I run a hose on the wall
it gets damp on the inside, maybe takes 8 - 12 hours

Nothing major, but the walls are storing the water

Does anyone know if my idea will work?
