Lightweight, stable and long-lasting, aluminium patio furniture will give you many years of use around pools, yards and patios. Although it is available in abundant colours and designs to complement any landscape decor and is virtually weatherproof, constant exposure to rain, ultraviolet rays, hail and other weather elements can cause the furniture's paint to flake and peel. Regularly repainting your aluminium patio furniture revitalises its appearance and prevents future corrosion. You can repaint your aluminium patio furniture with various techniques to restore it to its original beauty.
Clean the furniture with a mixture of 4.5 litres (1 gallon) water and 60 ml (1/4 cup) liquid washing powder. Using a stiff nylon brush, scrub the entire aluminium surface with the soapy solution to remove grime, oil and chalk residue.
Rinse the furniture with fresh water from a garden hose and dry the furniture with a soft towel.
Rub 100-grit sandpaper over the aluminium to sand away any peeling or flaking paint.
Sand the aluminium with 220-grit sandpaper until the aluminium surface is completely smooth and contains no rough or uneven consistency.
Moisten a clean rag with water and wipe it over the furniture to eliminate all dust and chalk. Thoroughly dry the aluminium with a soft, dry towel.
Apply one coat of oil-based metal primer to the exposed portion of the furniture. Using a paintbrush, brush the primer smoothly and evenly over the aluminium surface. Permit the primer to fully dry for the time span suggested by the manufacturer.
Turn the furniture piece over to expose the unprimed underside. Prime the underside of the furniture using the same procedure as before. Once the primer is dry, set the furniture upright again.
Spray two thin coats of acrylic enamel spray paint onto the exposed portion of the furniture. Hold the can 25 to 35 cm (10 to 14 inches) from the furniture and apply the paint using side-to-side motions without pausing. Let each coat of paint dry separately as directed by the manufacturer.
Turn the furniture piece over to expose its unpainted underside. Paint the underside of the furniture using the same techniques as before. Allow the paint to dry fully before using the furniture.
Do not use latex primer on oxidised aluminium; the ammonia in latex will negatively react with the oxidation.
