Was speaking to k rend today and they told me that if I seal the ft on the job I'm on just now I will lose all warranty. He then told me its self cleaning, nearly dropped my phone laughing.Yep lack of adhesion on that from looking, not been sealed on completion resulting in dirt sitting on the surface. I'd knock it off back to substrate and re do. There lies the issue of going over existing renders other than a thin cost t I wouldn't do it, too much weight. Depending on the thickness of the original you could have 40mm thickness on there, that's some pull on the substrate. Hand applied, machine applied, how mixed etc wouldn't make any odds for me.
