How to spray varnish on to sheet metal.

The paint should adhere to the prepainted metal surface. Wash the metal thoroughly with hot soapy water. Rinse the metal with a weak solution of water and ammonia and allow it to dry. Apply latex paint to the surface.

Once again read your product s instructions shake the can for as long as directed and use even continuous strokes. All you have to do is simply apply the vinegar to a clean rag and then wipe down the galvanized surface. Keep your coats thin for a smooth even finish. For best results keep the can parallel to the sheet metal surface and spray in a back and forth motion over the surface.

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. Once the metal has dried dampen a cloth with white vinegar and wipe the surface down. 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. Spray in a quick smooth and even pattern until the surface is covered.

The acidity of the vinegar will further abrade the metal. Apply 2 to 3 thin coats of rust inhibiting metal spray paint. Once you ve roughened the surface wipe the sheet metal with white vinegar and a soft clean cloth. Get your mask gloves and goggles on and test your spray paint to ensure it provides a thin fine mist.

Be sure to wait at least 2 hours before applying an additional coat. Rinse the metal and let it dry completely for several hours. The acidity of the vinegar will react with the metal treating the surface to promote paint adhesion. White vinegar is both effective and non toxic so it is much safer to use than your average industrial solvent.

Shake the can vigorously for 45 to 60 seconds and spray onto a cardboard box or the bottom. Acrylic latex provides the best coverage on prepainted surfaces. Apply spray paint to the sheet metal. Use a brush roller or spray can depending on your preference or the size and shape of the metal object.

Remove any handles or other attachments from the metal.
