When the paint on the apartments or commercial building to repaint. Under normal conditions that time rolls around every five to seven years. As one has probably discovered, there are many kinds of paint in a multitude of colors. Some can be used almost anywhere; others are designed for special purposes. There are different types of paints are used by the St Louis Commercial Painting contractors and companies. Exterior topcoat or finish paint-like most paints-is either solvent-thinned or water-thinned. The first type is known as oil paint, though it usually has an alkyd-resin base; the water-thinned type is called latex and is usually based on acrylic resins. The two types are comparable, although there are some differences that can be important, depending on the job to be done and the personal preference. Oil paint has excellent durability and penetrating and hiding properties, has good elasticity (to accommodate expansion and contraction of wood), forms a strong bond to the surface (especially on old painted surfaces), has good resistance to blistering and fair color retention, and is relatively easy to apply. Latex paint has similar properties, with these exceptions: has relatively better resistance to blistering or peeling and better color retention, especially in white. Because it is water-thinned, latex paint can be applied in damp weather or over a damp, but not soaking wet, surface; it’s easy to apply with a brush or roller and is a snap to clean up with soap and water. It dries so quickly as the water in it evaporates—in contrast to the slower, chemical drying process of oil paint—that one can usually recoat the surface the same day. On a particularly dry and breezy day, however, rapid drying can result in brush or roller marks showing on the finish coat. Also, latex house paint comes in relatively low gloss or flat finishes, and a coat of latex paint, when dry, is generally thinner than oil paint. Primer seals and prepares a surface for the best adhesion of topcoat paint. There are a variety of primers, each with special properties for use with different kinds of finish paint on different surfaces—wood, masonry, aluminum, steel and other materials. The label instructions on topcoat paint should indicate the type of primer. Stains are most often used on wood siding material, such as redwood, cedar and pine. They penetrate the wood and produce what is called a breathing coat rather than a solid film of paint. Stain has a dull and flat finish; it is gradually worn away by the weather. Semitransparent stains alter the natural color of wood without obscuring its grain or texture. Solid color, or opaque, stains have a higher concentration of pigment, so they color the surface and obscure the grain to a greater degree.
