Soft washing render with aluminium window frames.

[Rich C]

Hi all,

I'm hoping to pick the brains of you soft washing pro's this time round and I appreciate your time.

I've been asked to clean the render on this, my concerns are the metal window sills and what hypo would do to them.

The wood would be an issue however I'm not washing that high or close.

What would you guys use to clean this render and not get stung with issues?

Thank you

Usually hypo on anodised alluminium is ok , but I did have one bad experience see picture below , I would wet the window frames and sills down with water first obviously you need to wet all the walls as well , I would then apply the hypo mix then WFP the window frames with a small amount of water between coats , this will dilute and prevent any problems, we do dozens of properties per year and only once had an issue .
