I have an apartment in Turkey, there is one wall that takes a hammering over
the wet winter months, the wall is currently painted externally and
internally and is not on the ground floor, When I go out in spring there is
a little `dampness` on the inside of that wall, normal for turkish builds
and easily sorted with a quick scrape and a new coat of paint.
However I would like to at least improve the situation and even better if I
could solve it by trying to coat the wall with something to seal it.
I would be cautious about sealing the wall.
It sounds like you may have a masonry wall.
( Telling us the materials and thickness would be a great help.)
Many such walls can take in a lot of moisture which eventually is
If moisture were to get into such a wall at some joint such as a
window frame connection...
A surface seal would hold the moisture in the wall with a number of
possible bad results.
The dampness is on the roof terrace exit, the exit from the stairwell, there
are no windows and I have used silicon sealant around the door.
It appears to seep in from one side only and from about ground level to
approx 2 feet above, there does not appear to be any seepage from the roof
of the stairwell down.
The wall is single skin using a type of honeycomb brick between concrete
pillars and then skimmed over. I would reckon the wall is approx 7 inches
I presume if I sealed the wall on the outside then it could breath on the
inside if this was untreated. The wet Winter is only about 3 months and then
there is intense heat for the Summer months, with 2.5 months no rain at all.
Find the source of where and how moisture is enetering the wall and
put your seal there. It may not necessarily be the rain against the
wall but from above the wall. or someplace else., But determine the
source and go from there with your sealer.
