When refinishing furniture, there are a few different tools that you will need in order to do the job correctly. One of the most important tools that you will need is a sandpaper. This will help to remove any old paint or varnish that is on the furniture. You will also need a screwdriver in order to take apart the furniture so that you can sand it down properly. Once you have taken the furniture apart, you will need to use a paintbrush or roller in order to apply new paint or varnish. Make sure that you follow all of the directions on the can of paint or varnish so that you do not damage the furniture.
