Hi,

Can anyone tell me if there are any problems with painting straight on top of lime wash with masonry paint?  I am only asking this from the persppective of whether it will adhere etc.   I am not concerned about the lime render beneath "breathing".

Many thanks.

Yes, you are likely to get streaks in the limewash and bad coverage as it will turn out very flakey as it will not be able to penetrate the masonry paint very well

Many thanks Steve for your reply but does your reply refer to painting over masonry paint with limewash?

What is your view of painting over limewash with masonry paint?

Thanks again,

Lee

Yes, my last post does refer to painting over masonry with limewash.
If you mean, painting over the limewash on cement, then this will be fine as long as you wire brush the area(s) first to get any flaking limewash off.

Thanks,
Steve

Hi Steve,

I live in a recently converted barn which was lime washed about 3-4 years ago and now needs repainting.  I have seen your previous reply - but is it ok to use Dulux Weathershield on a lime washed stone building?

And does Weathershield retain it's 'breathability' when applied to lime wash?

Any advice will be most gratefully received.

I myself would re-limewash the barn as weathershield and other masonry paints do not allow the wall to breathe either.

Hope this helps,

Steve,
Thank you for your advice - I had asked so many people and never got a straight answer.
Have to say that Weathershield's blurb is not the clearest - if I wasn't quite so '*****' I might have just gone and painted 'breathable' waethershield on top of the limewash. . . glad I checked ('measure twice, cut once').
Looks like I'm in for a learning curve this summer 
Excellent site mate, cheers!

Great to hear that you are prepared to educate yourself where period properties are concerned. It will save you a lot of heartache in the future 

Thanks for your kind comments and you are welcome.

Happy Learning,
Steve
