Exterior filler for fresh render

[garyo]

Hi chaps.

I have a couple of 200mm x 200mm low spots in fresh render, probably only 2 or 3mm deep. Is there a product or technique I can use to build these out before painting, for instance some kind of SBR/cement/sand slurry used as a filler, or a particular paint/product?

Please don't say hack it all off.... pleaaaase!

Regardless of what you use to patch it a patch will be more noticeable than a dip.

Agree, render’s basically totally unsandable as it will just wear away which kind of makes any normal filling and making good really hard/impossible. You can’t even blend in paint edges if you have loose paint (well I can’t, some pros may).
How bad is it? most render will have the odd dip and will only show when the sun catches it...even jobs that I’ve seen done round here by very good plasterers which look mint, can show blemishes when painted white and the sun goes across it.

Thanks chaps . I think I might just paint it and see how it looks as the light hits it. We're going for a dark colour anyway which might help.
