Damp
Under our bay window the paint and plaster keep dropping off due to damp. Nowhere else is affected in the house but the paint only stays on a matter of days and then flakes and falls off. Does anyone have any remedies?

Hi Chiclanagirl
Do you have a tiled window-sill, we had this problem and nothing we did seemed to work, so we removed the tiles from the windowsill and we found that there was a cavity in the bricks that was filled with rainwater. Remedied this by draining as much water out as we could then uni-bonding the inside, filled it with cement then waterproofed the new sill and replace the tiles. We allowed the wall to dry out for the summer before rubbling down and uni-bonding the wall and re-painting.
Regards
Cristina

Re: Damp
How weird....we have exactly the same problem. I thought it was due to the bay being cement with no plaster, and was going to repaint in the summer, using a protective barrier....now I will explore further.

Re: Damp
If you can't source and cure the damp problem itself, then try using distemper (pintura al temple) paint which is breathable and so won't peel off even under quite serious damp conditions. The popular "plastico" paint commonly used here will start to peel away at the slightest whiff of moisture!

Re: Damp
Just to add. This I found through experience 
The "plastico" paint should never be used neat, it must always be thinned with water, otherwise it will never stick to any wall damp or dry.

Re: Damp
One year in and our place has a ripple in the porch, about a foot from the ground, the other side of that wall is the living room. So whats causing that -any ideas?
The rain certainly comes right in to the front door when its falling sideways so all the porch gets wet.

Re: Damp
Like a tidemark? If so, is classic rising damp. Many possible causes - lack of/ruptured/bridged dpm, groundwater (fed by the rain!) seeping up, exacerbated by rain splashing up from the paving adjacent to the wall, inadequate drainage of rainwater away from the wall...

Re: Damp
Well it seems like its raining sideways, it certainly comes right in the porch and soaks everything!
It will probably be caused by all of Hillybilly's suggestions - more work to do.....

Re: Damp
Under the Building Regs all new builds (and refurbs) should have dpms where appropriate and Susique says her house is just 1 year old.
