Thank you for your response on my Email. So if I buy AP77 masonry paint can you put over an old masonry paint which is years old and it still give you protection? Thanks
Assuming the previously applied masonry paint is clean, dry, sound and prepared as detailed in the Technical Data Sheet, Wethertex AP77 Flexible Smooth Masonry Paint can be applied over the top of most paints.
We would recommend testing for compatibility and adhesion prior to full application.
