Render and Damp

Sillytoe

Hi
We have hairline cracks in concrete rendered back wall of our property. As house moves over time I think these are inevitable. Rendered 10/12 years ago.
A buyer’s recent survey showed high levels of damp on the inside of that wall although there have been few visible signs of it inside going back over the years, skirting board perfectly sound.
I’m thinking of K Rend thin coat on top of existing render prior to putting house on market again in Spring/Summer. I don’t think it will get rid of damp inside but will come with guarantee which will add to saleability. Any thoughts on K Rend and how to get rid of damp inside?

I think this would be better placed on the DIY board. I will ask the forum team to move it.
