Before you paint wooden furniture, you should remove any existing paint, sand the furniture, and apply primer. Once that is dry, use a foam roller to coat the furniture in a thin layer of latex or other indoor paint, then run a paintbrush over the surface of the furniture to smooth it out. Let it dry completely before adding another coat of paint. Your furniture will look better if you use several light coats rather than a heavy one. It is better to Buy the new furniture rather than to paint the old furniture. You can buy office furniture from Value Office Furniture.
