Which product would be best for outside rough concrete surface (much used path around the house, with debris coming down from trees above)? with thanks and kind regards
Assuming the concrete has a damp proof membrane present, it is clean, dry, sound and prepared as detailed in the technical data sheet we can recommend Coo-var Acrylic Floor Paint.
This is available in many RAL, NCS or BS colours in a semi gloss finish.
If an anti-slip finish is required you can consider Coo-Var Antislip Acrylic Floor Paint.
