High-Performance Exterior Painting

The varied conditions and expectations faced by exterior painting programs also present a challenge to exterior painting contractors. The lessons gained at any finished project have improved color technology over time. As a consequence of these developments, today’s exterior paints can accommodate almost every condition that may occur during the execution of an New Haven County Exterior Painting project.

Considerations for Painting Based on Location

One of the most common conditions that must be met when it comes to exterior painting projects, according to exterior painting contractors and paint manufacturers, is the one dictated by location. Construction types and content choices vary depending on where you live. As a result, the type of exterior paint to use is determined by the place.

The Southwest, for example, is known for its masonry and stucco exteriors. Primers and top coats designed for cementitious materials are required for these substrates. Exterior painting contractors in the Southeast use weather-resistant formulations to withstand year-round exposure to wind and rain. Sun-resistant and UV-absorbing resinous formulations are used in mountainous areas, on the other hand.

Exterior Coatings that are Weather-Proof

Paint manufacturers have also created formulations to account for another major factor that affects projects: the weather. Exterior painting contractors take into account the weather conditions surrounding the project when deciding which products to use. It even has an impact on the applications and methods they can employ.

For surface protection in climates with high levels of UV rays, elastomeric-based or 100 percent acrylic paints are frequently used. To combat water-borne cracks, thicker-film elastomeric is used in windy and rainy weather.

Surface chalking and premature peeling can occur at temperatures below 50°F, while temperatures above 90°F can have a significant impact on surface preparation, application, and curing. During the project, exterior painting contractors must keep this in mind. Freezing-thawing cycles, on the other hand, require flexible primers and topcoats to cope with the fluctuating temperatures.

The Environment’s Role in the Choice of Exterior Coatings

Federal and local laws on environmental protection have influenced the design and manufacture of exterior coatings. Paints with the low-VOC formulations have been introduced. This aims to halt the harmful effects of VOC-emitting regular paints to the environment.

Painting contractors and paint manufacturers must comply with the U.S. Environmental Protection Agency’s (EPA) VOC-level standards at the national level. In the north east and mid-Atlantic states, the Ozone Transport Commission (EPA) Model Rule is in place. State-based air quality programs also watch strictly over VOC compliance that covers the building industry.

Compliance to these varying environmental regulations and agencies resulted in new formulations of exterior coating products for architectural, commercial and industrial painting. These are often low-VOC latex, water-borne or solvent alkyd products.
