Why Use Latex Paint for Painting Your Home’s Exterior?

If you’re considering painting your home, or hiring a company to do so, you’ll want to make sure that you or the firm you hire uses latex paint. Because home exteriors take a beating from sun, rain, snow and other harsh weather conditions, it’s important to ensure that the paint—your home’s first level of defense against damage—is strong enough to stand up to the elements. Latex paint provides a stronger barrier against things like the weather, UV rays and extreme temperature fluctuations—for example, a deep freeze in the winter or very hot and humid summers. As always, it’s ideal to paint when the temperature outside is between 50 and 85 degrees, because temperatures outside that range can make it difficult for the paint to dry properly, which can mean you having to go over the paint and fix flaws.

Resistant to Fading

First of all, since the outside of any home is going to be exposed to UV rays day in and day out, it’s important to consider fading when choosing paint. Thankfully, latex paint offers more protection against fading than other paints, particularly ones that are oil-based. Latex paint will remain true to color longer, despite being exposed to sunlight for years.

Permeable for Optimal Damage Resistance

The finish of latex paint is also ideal for preventing expensive, frustrating damage to your home. Latex finishes can be breathable/permeable, which allows for moisture to vaporize and evaporate before it can damage the wood fibers of your home. If you are using paint that isn’t breathable, and moisture seeps in, it can cause significant damage to your home, sometimes before you even notice, which can be costly to repair.

Adaptable to Extreme Temperature Fluctuations

Latex paint is also very adaptable to different temperature changes. For instance, drastic changes in temperature can cause wooden surfaces and siding to contract and expand. If you painted with an oil-based paint, that paint may crack, flake, or peel off when the wood underneath it contracts or expands. If you’ve used latex paint, though, the paint has the ability to “stretch” a bit and conform to the wood or siding underneath it. If you live in an area where the summers and winters drastically differ in temperature—say, in Chicagoland or the North Shore—you’ll want to be using a latex paint to avoid having to repair paint damage from weather fluctuations.
