A true antique coffee table in a style that you like may be hard to come by or beyond your budget. Rather than searching store after store for the perfect table at the perfect price, give an existing coffee table a makeover to make it look far older than it really is. Standard supplies from a home improvement store are all you'll need to give that table an antiqued or specialty finish suited to the room's decor.
Wipe down the coffee table entirely, including its legs, using a damp sponge. Allow the table to dry completely.
Place an assortment of heavy nuts and bolts in an old pillowcase or sock. These heavy items will serve as a tool to distress the table, making it look older than it is.
Grasp the opening of the pillowcase or sock and swing the load of nuts and bolts at the table, whacking it in various places to cause dents and wear. Aim for the corners and random areas along the top or sides to make the table look as if it has been in heavy use for many years. Hit the table with a hammer a few times in random places as well, using the side, claw and head of the hammer as denting tools. If the table has wooden legs, hit those a few times as well.
Cover your work surface with newspaper. Set the table atop the paper.
Sand the entire table with a fine-grit sanding block to scuff up any remaining shiny coating, which will allow the paint and primer to adhere better. Wipe down the table with a tack cloth to remove dust.
Cover any parts of the table you don't wish to paint, if any, with painter's tape.
Open and stir the primer using a stir stick. Pour some of the liquid into a paint tray.
Prime the entire surface using a paintbrush. Allow the table to dry completely.
Open and stir the main paint color, pouring some of it into a paint tray. Paint the coffee table using a paint brush. Apply a second coat if the primer is still visible beneath the paint. Allow paint to dry completely.
Mix a bit of dark latex or acrylic paint with some water in a disposable container until the paint is slightly thinned. Stir it with a stir stick to blend the liquids.
Brush the watery, dark paint over the entire coffee table, rubbing off excess with a rag, which also will push the dark paint into cracks and dents. Continue this process until the table looks aged to your liking. Allow paint to dry completely.
