Can anyone advise me on whether there is a 'right' sort of paint to use on exterior walls of an old granite house, please (and if so, what?!)? I have recently moved into the house and would like to give the exterior large granite stone walls a fresh coat of paint once the weather warms up a bit but don't want to compromise the 'breathability' of the granite walls. Very new to living in an old house so 'idiot's guide' would be appreciated!

Thank you!

Post up some pictures and where is the home located? Be careful with painting any old home. You change the vapor permeability of the wall if it didn't have paint before and can create unintended consequences.

Does the stone currently have paint on it?

Yes, already painted, just not sure what with

Since it's already painted you should be able to repaint with a quality latex house paint after cleaning it.


To verify the current paint is latex you'd wipe/scrub a small area with denatured alcohol. If it tries to dissolve the paint - it's latex. Products like 'goof off' and 'oops' will also work.
