Painting new galvanized steel roofing.

Many metal roofs are made out of galvanized metal which is a type of metal that has been covered with hot zinc in order to protect it from the weather. You can also use oil based alkyd paint but. Be sure to cover the entire surface so that you cannot see any primer left. Use your putty knife or scraper to scrape off any peeling paint or accumulated rust on your metal roof.

Galvanized metal roofs are usually painted with acrylic based paint. All you have to do is simply apply the vinegar to a clean rag and then wipe down the galvanized surface. Apply two topcoats of paint on top of the primer. Wipe the galvanized surface down with white vinegar.

Painting metal roofing provides you with a number of steps and decisions throughout the process. Although you can leave the steel panels unpainted many people choose to paint them a color that complements the remaining exterior of the structure. Painting a galvanized steel panel roof is not. However paint on metal roofs often peels or rusts in which case it is time to repaint it.

Painted metal roofs come with a baked on factory finish and you can re coat these as well as paint bare metal roofing with acrylic latex paint. Clean the steel with a chemical degreaser. Using your exterior metal acrylic based paint using the same paint tray that has been emptied of any remaining primer begin to apply the paint with a roller directly onto the galvanized steel roof panels in the same order you applied the primer. Galvanized steel on the other hand cannot be painted with an oil based or aluminum based paint.

The secret to painting galvanized steel is white vinegar. My house was built circa 1880 and still has its original terne metal roof which consists of individual metal shingles with an embossed decorative pattern. The vinegar is a mild acid which acts to etch the galvanized coating so the paint will stick. Proceed in small sections until you ve cleaned the entire surface.

White vinegar is both effective and non toxic so it is much safer to use than your average industrial solvent. Prime the surface with a primer made for metal. Spray the surface with the solution then scrub it with a clean lint free cloth. To ensure that you know what kind of metal your roof is made out of and what kind of paint you should use ask a professional roofer to inspect your home.

Galvanized metal requires either a zinc dust type paint or a latex paint.
