Colder temperatures and moisture on the surface can also result in staining or mildew. But you’ll want to pay attention to the surface temperature of the exterior walls of your house.
“If you can’t keep the palm of your hand on the exterior wall of your house for more than a few seconds, it’s too hot to paint,” DE Pay says. Check the label on the paint can for any instructions on the ideal temperature range, and follow DE Pay’s tips, below, for nailing the job.
In that case, you’ll need to use a certified lead-abatement contractor to prep the surface. Scrape out rotted areas and fill them with wood filler, then sand smooth.
To determine a paint ’s durability, we apply two coats to pine boards. Then we mount the boards on angled racks on the roof of our headquarters in Yonkers, N.Y., to see how well the paint withstands the elements.
Because the boards are angled, and not placed vertically as they would be on your house, they’re more exposed to light and weather. We also test for mildew resistance by placing painted panels on vertical racks in a shady area of our HQ’s campus.
CR's members can keep reading for ratings and reviews of the exterior paints that scored 72 or higher (out of 100) in Consumer Reports’ tests. If you choose one of our picks, you can expect your home’s exterior to look good for eight to 10 years.
On the Consumer 101 TV show, Consumer Reports expert Rico de Paz shows host Jack Rico how to give walls the perfect coat. Painting the exterior of your home isn’t the type of job that can be done at any time in the year.
In order for your paint job to turn out perfectly, the weather needs to cooperate. This is because how the paint dries is directly related to the temperature and conditions at the time of application.
If you’ve got perfect temperatures during the day, but then a sudden drop after the sun goes down, the paint will react and won’t cure properly. We’ve mentioned that summer is an ideal time to get your exterior paint job done.
Stick to these times of the year, and you’ll probably end up with fantastic painting weather ! Avoid rainy days, and always make sure all the surfaces you’ll be painting are completely dry.
You don’t want to try to paint outside in the middle of winter since it’s usually too cold for the paint to be able to dry and properly cure. Remember to think about the temperature at night too, since your paint will still be drying and you want to make sure the conditions are ideal.
If you live in a northern climate, you can sometimes keep going into fall, but most people don’t attempt to paint beyond November since it’s often too cold. Some southern areas are warm enough into early winter, so they can get away with painting much later into the year.
Of course, when you decide to paint will largely depend on the climate where you live, but if you stick to these general guidelines, you’re sure to end up with a flawless finish. The optimal painting season for house exteriors is typically regarded as summer.
However, “summer” doesn't mean the same thing (or include the same months) in all parts of the country, so it's more important to focus on days that boast the proper weather conditions, rather than how you refer to the season. For areas that experience hurricanes or monsoon-like conditions toward the end of summer, start painting earlier on in the season instead.
Extreme heat should be avoided too, as it can prematurely cure paint, causing it to dry almost instantly as it's applied. Temperature fluctuations are also an important factor to consider when deciding when to paint your home's exterior.
There are plenty of DIY home projects you can tackle, but a large-scale paint job on the exterior of your house probably isn't one. You plan for it, gather your gear together, invest in your favorite snacks, try (and often fail) to get a friend to come along, and hope that the all-important weather holds out.
Here’s another bit of good news: thanks to the continued development of quality formulas, there are some exterior paint options that are designed for application in even colder weather. As a couple of examples, take a look at Sherwin Williams’ Duration, or Benjamin Moore’s Regal Select.
The key to a healthy, sturdy paint application is providing a clean, dry surface. These are especially common in the early spring and fall, when the days get very warm but then become drastically cooler than soon as the sun goes down.
Keeping the sun around the corner from where you’re working cuts down on both the need to bathe in sunscreen and the issues that can come from your paint drying too quickly. These conditions can result in a finish that may eventually dry, but will exhibit reduced durability, gloss, and repairability.
Therefore, it is important to ensure your products, your substrate, and ambient spray temperature are all above 60 °F to insure proper curing of your paint film. Before you begin painting, remember these tips: If you store your products in an unheated area, make sure they are brought in to warm above 60 °F prior to mixing.
If the car you will be working on has been sitting outside or in a cold shop, make sure it has been given time to warm in the booth to raise the metal temp above 60 °F. In order to stand up to the steady abuse from being used and the weather, window painting will require attention to many details and a bit of patience.
The details are preparation and repair, choosing a good paint and proper application techniques. Easily encompassing up to 50% of the time necessary to paint an entire home, depending on window type or style and condition.
Exterior windows are always exposed to the worst the sun and weather can offer, plus additional wear from opening and closing. An average exterior window will need repainting much sooner than the siding.
Giving your windows the best paint job you can will easily pay for itself with easier maintenance and a greater amount of time before the need for a complete repaint. Windows are manufactured in three basic styles; sash, casement and fixed.
Casement windows open like doors with hinges on the sides. Paying special attention while preparing the surfaces before window painting will provide longer lasting and better-looking results.
Water has a tendency to enter the glazing and wood at these points. The paint can lose its adhesion and not show signs of peeling or blistering.
Cracks or splits in good sound wood are a frequent problem needing repair before window painting. Prime the entire area with a quick drying oil base primer.
Small multiple cracks can be sealed with a brushable elastomeric sealant. Sand smooth, prime with an oil base primer then finish paint.
Repairing rotten wood is possible if the damage isn’t too extensive. Replacing the wood section is the ideal repair method, but this usually involves a great deal of work and carpentry knowledge.
Sand or scrape to remove the paint from around the rotting area. Remove enough paint to expose solid wood around the rotted area.
Lightly sand the broken area and prime with an oil base primer. Prime all raw or repaired areas with an oil base primer.
If the window was previously painted with an oil base finish and you will be applying a modern acrylic paint, prime the entire window sash and frame. A quick drying oil base primer is a good choice in most instances.
Allow the primer to fully dry before proceeding with applying caulk or glazing putty. Do not fill the weep holes or the sash to the frame, unless the window will never be opened.
Replace missing glazing compound after the window has been primed with an oil base primer. Pre-war the putty by submerging 1/2 of the can in warm water for several minutes if needed and keep the can in the sun if several windows will be reg lazed.
Collect the excess putty with your free hand during this process. Smooth any ruff areas with your finger using light pressure.
Use these ideas as a guide and modify or combine according to your own needs and window design. The techniques used for window painting are variations of these two basic designs.
Now reverse the positions and paint the remaining areas of the inner sash. Allow the paint to dry then raise both sashes and finish the jamb.
The order for painting casement windows is edges, top and bottom of the sash, sides and then the frame. The rule is that the top, bottom and outside edges should be painted with the exterior color.
If possible remove the window sash from the frame and paint on saw horses. This will expose the entire frame and allow a more comfortable window painting experience.
Cut away the excess by carefully running a sharp razor knife close to the wood-glass edge then remove the excess with a single edge razor blade. The best seal is achieved with a small bead of printable clear caulk after the excess paint is removed.
