Apply primer to the surface of the furniture you want to paint, using a paint roller. Primer helps paint adhere better to the surface and prevents the paint from warping some materials.
Roll on a coat of paint with a satin finish on the piece of furniture. Wait for the coat to dry, then apply a second coat. Use any color you like for this step.
Pour equal parts of clear acrylic glaze and white latex paint into a paint bucket or a paint tray. Mix it thoroughly.
Dip a roller in the glaze and paint mix, then apply it to a small section of the furniture. Working in manageable sections gives you more control over the result. Adjust the size of the section you work on to an area you can work before the paint begins to tack up.
Hold a wood-graining comb against the edge of the piece of furniture at a 45 degree angle. Drag the comb across the glazed surface of the furniture. This tool works best in the tight corners that other wood grainers can't reach.
Place a wood-graining rocker against another glazed portion of the furniture and drag the rocker toward you, letting the rocker sway as it moves. The rocker will create a wood grain pattern across the surface of the furniture.
Alternate between using the wood-graining comb and the rocker to create a natural wood appearance. Also vary the angles and the directions in which you hold the tools to create some variation in your faux grain to increase its apparent authenticity.
