I have recently moved into a new home and have no past experience of
all this stuff. The home buyers valuation noted that i had penetrating
damp due to the rendering on the exterier walls being porous. This has
led to the internal walls in the upstairs bathroom and bedroom being
damp. The advice was to strip back all the render and replace with new
mix and non porous sand and cement layer. Its quite a costly job and i
just wondered whether it would be possible just to simply paint the
exterior with a non porous paint. Or is it too late will the damp then
remain trapped in the bricks and rendor or will it dry out in time? I
guess i was just lloking for a cheeper option any ideas?

The cheap option is to paint the render with a pliolite based paint from
Johnstones or one of the other trade outlets. The paint itself isn't
cheap, but magnolia and white is often on special offer. The walls
should dry out to the inside over time. Ordinary masonry paint would
almost certainly be a waste of time
