Our house was built around 1905. It has a porch to the front door with
half-height brick walls with windows all around. The walls are very
It did have render on the outside to ground level. I have chipped most
off (some was very loose) and it seems very hard, so I suspect it is
cement based, and so not breathing. I can see no evidence of any
attempt to create a DPC. Internally, it looks like someone has used a
'special' paint that may be water proof.
The brick work is in poor condition, so will need to be rendered.
Should I inject a DPC before rendering? Or can I just use a lime render
without a PDC?
Internally, the porch is unheated. It has quarry tiles, but I do not
know what they sit on.
Any advice most welcome. My wife is keen for me to get on and
re-render, but I have told her the wall will need to dry for several
years before I get around to it!
