Patio furniture has to face four seasons and all sorts of inclement weather. These punishing conditions can easily degrade the outside and structure of any material. Metal furniture stands up better to harsh circumstances, but ferrous metals such as iron and steel can rust. Aluminum does not rust, and cast aluminum has a strength like ferrous metals. In case your cast-aluminum patio furniture has become weathered with use and time, you can redo it with the right materials and procedure.
Sand that your cast-aluminum patio furniture with moist, 120-grit sandpaper, or a handheld rotary tool with a 120-grit sanding attachment, even until it has a dull, even surface.
Spray off any sanding debris with a garden hose.
Dry the surface of the furniture with a sterile cloth.
Clean the sanded surface of the furniture with mineral spirits employed with a sterile cloth.
Move the furniture to a well-ventilated area out of direct sunlight.
Put on a respirator.
Spray a coat of epoxy primer over the whole surface of the furniture. Allow the primer to dry completely based on the manufacturer’s instructions.
Spray a coat of polyurethane topcoat paint to the whole surface of the furniture. Allow the topcoat paint to dry completely based on the manufacturer’s instructions.
