Undertaking an exterior painting job for your home is a big project. For do-it-yourselfers, it can be rewarding and satisfying to see the transformation that new paint can bring. But the job isn’t easy and shouldn’t even be started without some basic understanding of the process. To help you, we want to present some tips that will help in troubleshooting exterior paint problems.
Step One in any painting job is preparation of the surfaces, which can prevent many common problems. This means making sure the walls and trim areas are dry, clean and free of dust and dirt, and that they’re thoroughly sanded and scraped to remove any old paint that’s peeling or chipping.
Here are some painting issues that you’ll want to know about when troubleshooting exterior paint problems.
Blistering
When paint forms blisters, the culprit is most often moisture. Blisters also can be caused by applying an oil-based paint over latex or painting in very hot weather. Blistering also may happen when newly dried surfaces are exposed to water, such as rain. Fix this problem by painting during a non-rainy period, not using oil-based paint on previous latex, and doing the necessary sanding and scraping prep.
Peeling
Paint can peel when it is applied over surfaces that aren’t dry. Peeling also can happen when moisture that’s inside the home “leaks” through. If there’s a lot of peeling of the old paint and you believe moisture is to blame, a latex paint for the new job would be the best choice. In addition, a surface that’s not been cleaned properly or has a very glossy finish can also lead to peeling. Prep by sanding, cleaning and scraping.
“Alligatoring”
When paint on a surface begins to look like an alligator’s hide, it usually means there’s a problem with it sticking to the surface below it or that the second coat has been applied over a still-wet first coat. The result is the paint shrinks into little segments, like a reptile’s hide. Proper sanding, scraping and timing between coats will prevent this problem.
Drying issues
Paint will be slow to dry if the paint is of poor quality, if it’s applied too heavily, or if you paint when the humidity is very high. The key to success in all types of paint jobs is to start with a high-quality paint from a leading manufacturer such as Sherwin-Williams or Benjamin-Moore.
Mildew
If your exterior surfaces have mildew, clean first with a homemade or commercial bleach-based compound. Paint should never be applied over mildew, because no paint will contain this growth.
Wrinkling
This problem happens when paint runs, usually because the paint is too thick to dry quickly enough or you’ve painted when the outside air temperature is too cold. Prevent wrinkling by using the appropriate paint thickness, not painting in cold weather, and making sure to apply smooth, even coats. Previous wrinkles need to be sanded well before new paint is applied.
