Vinyl siding panels that have been repainted sometimes warp or buckle.
What Causes It?
Vinyl siding warp is usually caused by painting a home's vinyl siding in a color darker than the original or by using a type of paint that is not specially formulated for vinyl.
How to Solve It
Top-quality acrylic latex paint is the best type of paint to use on vinyl siding, because the superior flexibility of the paint film enables it to withstand the stress of expansion and contraction cycles caused by outdoor temperature changes. We recommend Regal® Select Exterior REVIVE™ for Vinyl Siding, a premium Benjamin Moore paint formulated specifically for optimal performance on vinyl siding and trim. In addition, choose colors that are safe for vinyl—like our Colors for Vinyl Siding collection. With hundreds of colors to choose from, it's easy to refresh weathered or faded vinyl siding without the risk of warping.
Siding that has already warped or buckled should be assessed by a qualified siding or home repair contractor. In some cases, warped sections may need to be replaced or repaired before painting begins.
