I have built a courtyard shape retaining wall out of solid concrete blocks, at the back of the wall is clean gravel and drainage, I want to render the inside walls but as it is a shaded area I presume I’ll get quite a bit of moss/algae growth, I am looking for something that would be pressure washer friendly as I think a sand/cement render would not be hard wearing enough, the render is more for aesthetics rather than stopping damp coming through, I was looking at Vandex BB 75.
Any information would be greatly appreciated and obviously the cheaper the product the better!
Kind regards,
Kev.
