Good Morning Ben
Thank you for your question.
Stormdry Masonry Protection Cream would need to be applied to a bare substrate. Any paint applied prior would prevent Stormdry from penetrating correctly. This paint would need to be removed in order for the Stormdry to work effectively.
Any further questions please feel free to contact us directly on 01403 210204.
Kind regards

Can this product be painted over brickwork that has already been painted and will it work as effectively? Thanks
