Thanks to improvements in technology, a range of faux finishes such as spray-on leather, and an explosion of new colors to complement every hue in your decorating palette, you can now spray bold, new life onto your old plastic chair or doorknob. Spray painting is faster and lasts as long as brush paint and the finish is actually smoother than what you'd get with a brush.
On The Early Show, Real Simple magazine's Kris Connell showed how to do it.
Four ways to use spray paint on a variety of different surfaces, from Real Simple magazine.
Metal Doorknob: Spray paint is great for metal fixtures such as doorknobs, switch plates, file cabinets, etc. Spray paint creates the smoothest covering, and most brush paints don't come in metallic finishes. You should add primer or sand, depending on the object and the paint.
Plastic Chair: Yes, you can spray deck chairs, tables and planters. At one time spray paint would bead up on slick plastic surfaces, but now new paints are specially formulated to adhere to plastic items. Remember to shake the can often. A fine mist is better than a heavy one.
Wood Stool: You can use spray paint on stools, doors, coat racks, shelves, frames and ceiling fans. Remember that wood is porous and must be sealed before you paint it. Apply a coat of aerosol primer to any wood surface, even if it's varnished. Sanding a glossy or raw wood beforehand will result in a better finish.
Wicker Nightstand: You can spray paint most wicker surfaces from chairs, tables, and nightstands. Spray paint is great on wicker because brush paint tends to leave gobs of paint.
