I am looking for paint suitable for external masonry steps but in a matt finish. These are for steps up to a front door in a victorian terrace in london. Can you suggest a product?
Assuming the steps are bare concrete, they are clean, dry, sound and prepared as detailed in the technical data sheet you could consider Coo-Var Anti-Slip Acrylic Floor Paint.
This is available in a range of colours in a matt finish.
