We'll Paint You a Masterpiece
The primary purpose of exterior paint is to protect and preserve the exposed walls and surfaces to which coatings are applied. Maintenance can be done to prevent damages, but often owners prefer a complete overhaul of their exterior. In these cases, the surface needs to be prepared before any painting or staining. Whether the surface is concrete, wood, stucco, vinyl, metal, or siding, both primers and finish coats need to adhere to the material. This means mildew, dirt, dust, old coats of paint or sealant, algae or oxidation must be cleaned of and eventually treated.
There are two types of interior paints to choose from: latex (or water-based) and oil (or alkyd-based). Each one has distinct advantages and drawbacks. Latex paint dries quickly, and water-based interior paint is typically non-flammable and has very little odor because of low levels of volatile organic compounds. It is available in a wide variety of finishes: matte, semi-gloss, gloss, eggshell and satin and can be tinted to match any color swatch or shade. Latex paint is not suitable every time: metal and wood surfaces must be sanded and primed, latex paint offers poor adhesion to uneven or dirty walls.
Oil-based paint gives smooth and durable surface that resists staining and shrinkage. It is recommended in high-traffic areas and wooden baseboards. On the negative side, oil paints do emit a strong odor, which can linger for some times. Common paint problems come from humidity: hot, humid climate can have a major impact on the quality of an interior painting job. Additionally, high temperatures can cause paint to dry too quickly, creating cracks. Other common issues include improper surface preparation such as: unfilled holes in drywalls, traces of wallpaper or older layers of paint.
