Hi,
First time poster who knows nowt about plastering.
I bought a 1890s terraced house in 2010. The walls are solid and the back wall of the house has a damp problem. It has a sand and cement rough cast render that has been patched by the previous owners. The inside is also plastered in sand and cement. There are three damp patches down stares that are slowly growing. There is no mould on them but there is a furry deposit that falls of like dandruff. When I put a cable through the wall the brick dust from deep inside the wall was damp.
A few days ago i chopped some of the render off the outside of the wall and it was damp behind the render, which sounded hollow and came off very easily.
I have checked the gutters and they are all fine. The roughcast wasn't painted up until last year when I painted it to see if it made any differece. It didn't.
My questions are
- Is the cracked cement render the problem?
- Do I need to have it replaced with lime render and if so, do I need to do the whole side of the house or just the first floor?
- Do I need to do inside as well?
- I would never attempt to do the plastering myself but would I save much money by doing the hacking off myself?
- when hacking off does everything have to come off? The top 15mm practically fell off where as the 5mm against the bricks is stuck like sht to a blanket.
Sorry for so many questions but I would greatly appreciate any advise.
