The paint on your home sends a message. If it’s fresh and sleek, your home looks well-kempt and impressive; if it’s peeling and chipped, it looks unmaintained. Peeling paint can’t be repaired by simply painting over it. If it’s not fixed, it can lead to worsening adhesion and substrate damage. At Sundeleaf Painting, we provide high-quality exterior painting services for high-end homes near you in Portland, Oregon. Here, we discuss what causes peeling paint and how to remedy it.Key TakeawaysPeeling paint can be caused by moisture intrusion, insufficient preparation, UV exposure, and substrate movement.If your home’s exterior paint starts peeling, you’ll need to determine whether spot repair is sufficient or if full repainting is the better option.Removing peeling paint involves testing for lead paint, using hand scraping or chemical stripping, sanding, cleaning, and applying a primer and topcoat.To prevent peeling paint from coming back, repair moisture problems, use the proper paint system, and maintain exposed surfaces.Sundeleaf Painting provides exterior painting services for high-end homeowners in Portland, Oregon.Why Does Exterior Paint Peel?Exterior paint takes a beating from wind, rain, humidity, and other elements, and it doesn’t last forever. Paint can peel for several reasons, and the most common ones include:Moisture intrusion: When moisture enters your siding from rain, snowmelt, or high humidity, it can saturate the substrate and then evaporate, which causes the paint to push off and start to peel.Inadequate preparation: If preparation doesn’t include primer or paint is applied over dirty or damp surfaces, the paint won’t adhere well enough and can peel down the road.UV exposure: Long-term UV exposure, especially during the painting process, can affect the paint’s curing process and cause air bubbles underneath, which will eventually crack and peel.Substrate movement: Certain substrates like wood will expand and contract over time, which can cause the paint to peel.Using incompatible coatings can also affect the paint’s adhesion and result in peeling.What Should You Do When Exterior Paint Starts Peeling?If you notice that your home’s exterior paint is starting to peel, you should:Inspect the extent of the peeling, cracking, and flakingIdentify whether wood, metal, masonry, or previous coatings are exposedDecide whether spot repair or full repainting is neededSpot repair is often sufficient if the peeling is small and only affects a single trim piece or board, while full repainting is the better choice if the peeling spans multiple areas, the surrounding paint is faded, or the peeling is caused by moisture intrusion or poor adhesion.Safe Paint Removal and Surface PreparationIf your home’s exterior paint is peeling, you can’t simply paint over it with a new coat, as it won’t fix the underlying problem and can cause worsening adhesion. Instead, you will need to remove the peeling paint and carefully prepare your surface before repainting. This involves:Testing for lead if the home was built before 1978 (hire a professional if lead is found)Putting down a tarp or other form of protection to avoid a big messUsing hand scraping or chemical stripping to remove peeling paint, avoiding pressure washingSanding sharp edges between bare spotsBrushing away dust and cleaning the siding with mild detergentApplying an exterior-grade bonding primer before applying your final topcoatIf you don’t want to handle all this by yourself, turn to the skilled professionals at Sundeleaf Painting.
