A good surface preparation and following the method statement / recommended system procedure of Ritver is an ideal recommendation for the application of Ritver Epoxy Zinc Rich Primer (HB).
For Metals:
In case of mild conditions of application, remove the previous coat with a mechanical tool, wire mesh, or a mild sweep blast is to be done.
In case of detailed Surface preparation is warranted, remove all wax, oil and grease should be removed by solvent cleaning in accordance with the guidelines given by SSPC-SP1. Where necessary remove weld spatter and round off all rough weld seams and sharp edges to a smooth surface. Ideally abrasive blast clean to a minimum standard of Sa 2- Swedish Standard SIS 05 59 00 or ISO 8501-1:1988. Any surface defects revealed by blast cleaning should be ground, filled or treated in a suitable manner. After blasting, remove dust from the surface. The surface to be coated must be clean and dry with Ritver Epoxy Zinc rich Primer (HB) before applying the top coat
Exclusions for successful application include perpetually wet surfaces and also large cavities on metal and wooden surfaces.

Adequate ventilation is an ideal situation as it helps in drying and the good application itself. Avoid high humid conditions i.e., 95% when condensation is likely to interfere and also when the surface temperature is at least 3c above dew point.

Application:
A normal brush or a roller may be used for difficult shapes or touchup; however, additional coats may be required to achieve the recommended film thickness. The method of application is recommended for stripe coating welds, edges, rivets etc.
To be done by Airless spray 2000-2400 psi. Nozzle size: 0.015-0.017 inches or conventional spray at 50 60 psi. It can even be done with a roller.
It is generally recommended to give a mist coat followed by a full coat.
One can add Ritver Epoxy thinner for achieving spray viscosity of app 40 45 secs on Ford cup 4 ASTM at 30 C and for ease of ion: Over diluting would result in a sag and run downs.
STORAGE & SHELF LIFE
Under dry and cool condition, Storage stability can be sound up to 18 months in original sealed containers.In no way should the component A & component B be mixed and kept.
