The present invention relates to a coating system comprising a first two-component waterborne coating composition comprising a binder component 1A and a curing component 1B and a second two-component waterborne coating composition comprising a binder component 2A and a curing component 2B. The first two-component waterborne coating composition comprises a first coalescent package comprising at least one coalescent and has a minimum film formation temperature less than 5° C. The second two-component waterborne coating composition comprises a second coalescent package comprising at least one coalescent and has a minimum film formation temperature from 5° C. to 25° C. A method of preparing a coating is also disclosed.
A coating system comprising:
The coating system of any one of the preceding claims, wherein the first two-component coating composition has a pigment volume concentration (PVC) of 15 to 20%, and the second two-component coating composition has a PVC of 7.5 to 12.5%.
