We bought a house a couple of years back which was re-rendered around ten years ago. Speaking to local builders, they remember the gang who did the job as not being much cop. i.e. the job was done on a price. As far as I can see, it is basically a case of making it good and painting with masonry paint.
As you can see from the pics of the south and west walls, there are unsightly damp patches and a bit of mould. I am guessing they are as a result of the render not being properly waterproofed.
I have also attached a couple of snaps of cracks in the render. The doesn't seem to be blown around the cracks, but do I need to chase out the cracks or should I fill them.
The questions I need answered are:
Can I get rid of the damp patches without covering with paint?
If I am just going to apply sealant, what should I use?
Do I need to worry about the cracks?
and if so how can I fix them without spending a fortune?
What paint / sealant should I use?
Is the lack of DPC on these two walls adding to my problems?
Thanking you in advance for your straightforward and cheap to implement suggestions
