When it comes to painting, preparation is key. If you want your paint to adhere to the surface, especially if it is varnished, you need to sand it until it is smooth. However, you don't want to remove the finish completely. There are several ways to prepare a surface for painting, but one of the most effective is to use an oil-based primer.
This type of primer will stick to varnished or sealed wood and can then be painted over with latex paint. If you don't want a painted finish, there are other options available. Milk paint is a biodegradable and non-toxic option that is ideal for use on wooden furniture. You can buy it in powder or pre-mixed form, or even make it yourself at home. If you mix it with an equal amount of adhesive agent, you don't need to sand the part before you start. Chalk paint is another great option if you don't want to sand the surface first.
It adheres to many surfaces and doesn't require any preparation. It will also help you prepare metal, vinyl, glass and other surfaces for future painting if you don't use the whole gallon.
