Painting galvanised steel roof.

Painting a galvanized steel panel roof is not all that different from painting other metal objects but you must ensure that the surface is perfectly clean before beginning the application process. White vinegar is both effective and non toxic so it is much safer to use than your average industrial solvent. 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. The secret to painting galvanized steel is white vinegar.

They are also faster to dry allowing a painter to turn a job around quicker. All you have to do is simply apply the vinegar to a clean rag and then wipe down the galvanized surface. Certain roofing materials such as terne tin and galvanized steel accept waterborne coatings more readily than oil based coatings. A paint which will stick well like self etching primer is good and it s necessary if you have real rust.

Acrylics are also more flexible than oil and thus handle movement in the metal better. Be sure to cover the entire surface so that you cannot see any primer left. Find either oil based or acrylic based paint at your local home improvement store. Get off as much paint or rust as you can.

However paint on metal roofs often peels or rusts in which case it is time to repaint it. 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. Use your putty knife or scraper to scrape off any peeling paint or accumulated rust on your metal roof. If you re attempting to paint siding panels roof flashing or other materials that have seen exposure to the elements a thorough cleaning is necessary to eliminate any organic contaminants from the outer surface.

If you have a kitchen then you probably already have this handy solution. Galvanized metal roofs are usually painted with acrylic based paint. 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.
