When you want to make a change in your home, painting your furniture is an excellent place to start. No matter what type of paint you use (i.e., latex or oil), if done properly, it will make a nice difference. Interior furniture can be painted easily and the finished look can be spectacular.

However, before starting this project there are some important things that need to be considered:
1.) Interior and exterior finishes and paints should not be used on painted wood furnishings because they contain wax and do not adhere well to paint; these paints also lack adhesion properties for other coatings such as polyurethane or lacquer. Interior finish should only be used on unfinished wood surfaces.
Interior semi-gloss or satin paint is the best to use on painted wood for several reasons:
a.) Interior, oil-based paints are preferred over latex because they provide a harder wearing surface. Interior oil paints stand up well with normal wear and tear in most environments. Interior latex, also known as alkyd enamels have improved greatly with recent technology, but still do not offer the same durability as oil-based paints. Interior finish quality is measured by the amount of light the paint transmits through it. The more light transmitted, the better quality it is considered to be. Hence interior finishes are usually much brighter than exterior finishes because they are made to let in more light; this helps make them easy to clean when necessary. Interior varnishes block light and are frequently used to create dramatic rich, deep sheens. Interior latex has a slightly lower resistance to abrasion than interior alkyd enamels; however, this difference is very slight. Interior latex will also yellow more than an interior alkyd enamel over time because it oxidizes more rapidly than oil-based paints. Interior varnishes stand up well under high moisture conditions such as kitchens or bathrooms where furniture is frequently dusted with water from washcloths or sponges. Interior varnishes can also be cleaned easily if they become stained from spilled beverages or food particles by rubbing the area with a mild solvent such as mineral spirits and re-coating after drying
b.) Interior latex paint has more hiding power or better color retention than exterior paint. Interior varnishes have more hiding power than exterior varnishes because they contain a pigment package that is made to bond with the resin binder of paint. Interior latex has slightly higher gloss retention than interior alkyd enamel paints. Interior neatsfoot oil-based paints have better abrasion resistance properties compared to oils used in exterior oil base paints for wood furniture. Interior polyurethane formaldehyde finishes are typically more durable and tougher than an interior acrylic lacquer because they are formulated with higher cross-linkage of resins for added hardness and durability
2.) Interior finishes are also excellent choices when painting painted wood furnishings because they are easy to clean, dry quickly, and are not subject to chalking or fading. Interior oil-based polyurethane paint is the best choice for painting most painted wood because it gives you several advantages over interior acrylic lacquer.
Advantages over an interior acrylic lacquer:
a.) Interior latex provides excellent leveling which means that it dries without surface stripes or brush marks, unlike exterior finishes. Interior varnishes provide very little leveling so if you are planning on applying more than one coat of varnish, it is important to sand between coats using steel wool and a fine abrasive pad to create a smooth, flat surface so the next coat will not have a brush or roller marks that need to be leveled out. Interior urethane enamel has better leveling properties compared with exterior latex paint because exterior latex paint dries to a more porous, less hard surface compared with interior latex which has a higher solids content. Interior urethane enamel is not as tough as exterior urethanes because it does not contain an additive called alkyd resin which makes exterior finishes more durable
b.) Interior acrylic lacquer offers excellent hiding power but has minimal durability for heavy use settings such as dens, living rooms, or family rooms where furniture is used frequently and subject to heavy wear from the upholstery fabric. Interior oil-based paints have better hide and deeper color saturation than interior latex paints because there is greater penetration of paint into wood pores. Interior polyurethane formaldehyde finishes are about twenty times thicker than an interior lacquer so they offer much
