The acidity of the vinegar will react with the metal treating the surface to promote paint adhesion.

How to spray varnish on to sheet metal.

Rinse the metal and let it dry completely for several hours. Use a brush roller or spray can depending on your preference or the size and shape of the metal object. After removing loose paint first apply an orbital sander using 60 grit sandpaper working up to 100 grit sandpaper for a smooth finish. Apply a wire brush and scraper combo to the metal first to remove all loose paint and rust or to scuff up the surface of aluminum or galvanized metal.

Let the vinegar air dry and then choose. Keep your coats thin for a smooth even finish. White vinegar is both effective and non toxic so it is much safer to use than your average industrial solvent. Once again read your product s instructions shake the can for as long as directed and use even continuous strokes.

The paint should adhere to the prepainted metal surface. Acrylic latex provides the best coverage on prepainted surfaces. Apply 2 to 3 thin coats of rust inhibiting metal spray paint. Spray in a quick smooth and even pattern until the surface is covered.

The acidity of the vinegar will further abrade the metal. Once the metal has dried dampen a cloth with white vinegar and wipe the surface down. On older galvanized metal surfaces where the zinc coating has begun breaking down known as white rust use a wire brush or fine sandpaper to remove the chalky film before cleaning it. Apply latex paint to the surface.

Rinse the metal with a weak solution of water and ammonia and allow it to dry. Hold the spray paint can 12 to 24 inches 30 4 to 60 9 cm from the surface. For best results keep the can parallel to the sheet metal surface and spray in a back and forth motion over the surface. Get your mask gloves and goggles on and test your spray paint to ensure it provides a thin fine mist.

Once you ve roughened the surface wipe the sheet metal with white vinegar and a soft clean cloth. Apply spray paint to the sheet metal. Wash the metal thoroughly with hot soapy water. All you have to do is simply apply the vinegar to a clean rag and then wipe down the galvanized surface.

Remove any handles or other attachments from the metal.
