Cast aluminium furniture has steadily replaced cast iron furniture for several reasons. Cast aluminium resists rust much better than cast iron, even if the cast aluminium is exposed to air. Cast aluminium furniture is lighter than cast iron and can easily be painted any colour to match your indoor or outdoor decor Painting your cast aluminium furniture will give your furniture a customised look and allow you to change the colour to match any palette as often as you desire.
Clean the cast aluminium furniture with warm water and washing up liquid or an environmentally friendly commercial cleaning solution if the furniture is not brand new. Allow the furniture to dry thoroughly.
Wipe down the cast aluminium furniture with a clean rag just before priming to remove any light dust or debris.
Paint a metal primer on the furniture using a natural bristle brush. Let the primer dry according to the manufacturer specifications. Apply a second coat if the manufacturer recommends it.
Wipe the primed cast aluminium furniture with a clean rag immediately before painting to remove any new dust that accumulated while the primer was drying.
Paint an oil-based or alkyd paint on the aluminium furniture using either a natural bristle paint brush or natural nap roller. A combination of a brush for tight spots and a mini-roller for larger, wider areas on the furniture works well.
You can skip using primer if you are painting cast aluminium furniture that is in good condition. Cheaper latex paint will scratch off of metal furniture more easily than an oil-based paint applied on a primer.
