Armour prime is a two-pack system that acts as a sealer on porous substrates such as concrete and will consolidate a friable substrate such as that of asbestos cement. It acts as a barrier coat on bituminous substrates and improves adhesion to difficult substrates such as non-ferrous metals.
The earliest overcoating time is when the primer system has dried but still has a slight tack, eg; at 20°C this would be after ~ 2.5 hours. The latest overcoating time is 25 hours after the primer application. After this it is necessary to re-apply the primer.
