How to spray varnish on to sheet metal.

Remove any handles or other attachments from the metal. Apply spray paint to the sheet metal. The paint should adhere to the prepainted metal surface. Acrylic latex provides the best coverage on prepainted surfaces.

Once you ve roughened the surface wipe the sheet metal with white vinegar and a soft clean cloth. Wash the metal thoroughly with hot soapy water. Let the vinegar air dry and then choose. For best results keep the can parallel to the sheet metal surface and spray in a back and forth motion over the surface.

White vinegar is both effective and non toxic so it is much safer to use than your average industrial solvent. After removing loose paint first apply an orbital sander using 60 grit sandpaper working up to 100 grit sandpaper for a smooth finish. Keep your coats thin for a smooth even 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.

The acid in the vinegar will act to etch the metal and help the paint adhere. Spray in a quick smooth and even pattern until the surface is covered. Be sure to wait at least 2 hours before applying an additional coat. Hold the spray paint can 12 to 24 inches 30 4 to 60 9 cm from the surface.

Once again read your product s instructions shake the can for as long as directed and use even continuous strokes. Apply latex paint to the surface. The acidity of the vinegar will react with the metal treating the surface to promote paint adhesion. Once the metal has dried dampen a cloth with white vinegar and wipe the surface down.

Rinse the metal with a weak solution of water and ammonia and allow it to dry. Apply 2 to 3 thin coats of rust inhibiting metal spray paint. Shake the can vigorously for 45 to 60 seconds and spray onto a cardboard box or the bottom. All you have to do is simply apply the vinegar to a clean rag and then wipe down the galvanized surface.

Get your mask gloves and goggles on and test your spray paint to ensure it provides a thin fine mist.
