Hi, Got this render clean to do and just a tad unsure on the best way to tackle the efflorescent on this render.
Any thoughts would be appreciated.
Cheers
John

are you sure its effervescence ?
are you soft washing it?
personally I'd need a close up photo - but I would say from that a good hypo solution is required to get off all the organic stuff and see what it looks like after
if your sure then a quality brick cleaning cleaner/acid will be required - then treated with a control chemical to prevent re-occurance
however I think your looking at water staining degrading the surface - but as I say need a better picture

Thanks for your reply Darran,
I tend to agree with you on the water staining, I've done quite a few sand & cement render cleans with some similar type staining but in much smaller areas.
A good 4% agitated hypo wash should do the trick
cheers
