Depending on its application purpose of this coating system e.g (2 coats or 3 coats system), an applicator could apply a compatible coat to its existing primer to build up its DFT or use an identical primer apply to build the DFT. All these are performed with transparency and permission from Client or owner's Rep.
Do ensure the surface is cleaned and free of dust, oil and foreign contaminant prior to painting.
