1. A method for adding pigment to a two-part reactive resin coating formulation comprising:
providing a two-part reactive resin coating formulation in a set amount, the two-part reactive resin coating formulation comprising a resin part and a hardener part and having a known first stoichiometric ratio of the resin part to the hardener part;
providing a two-component dispensing system separate from the two-part reactive resin coating formulation, the two-component dispensing system having a first compartment containing a pigmented resinous composition and a second compartment containing a hardener composition, the first and second compartments are adjoined to each other;
dispensing the pigmented resinous composition and the hardener composition from the first and second compartments in a second stoichiometric ratio that matches the known first stoichiometric ratio of the two-part reactive resin coating formulation;
mixing the pigmented resinous composition and the hardener composition to form a dual pigmented resin-hardener dispersion having the second stoichiometric ratio that matches the known first stoichiometric ratio of the two-part reactive resin coating;
dispensing the dual pigmented resin-hardener dispersion into the two-part reactive resin coating formulation thereby increasing the set amount; and
mixing the dual pigmented resin-hardener dispersion with the two-part reactive resin coating formulation to form a pigmented two-part reactive resin coating formulation without deleteriously affecting the known first stoichiometric ratio of the two-part reactive resin coating formulation.
