DESCRIPTION

Warping or buckling of vinyl siding panels that have been repainted. 

POSSIBLE CAUSE

• The likely cause is that vinyl siding was repainted with a darker color paint than the original color. Dark paint tends to absorb the heat of the sun, transferring it to the substrate. When vinyl siding expands dramatically, it is not able to contract to its original dimensions.

SOLUTION

See Lead Information.
 

• Request a Sherwin-Williams product which has VinylSafe^® paint colors which allow you the freedom to choose from 100 color options, including a limited selection of darker colors formulated to resist warping or buckling when applied to sound, stable vinyl siding.
   

• If you are not using products with VinylSafe^® paint colors, paint vinyl siding in a shade no darker than the original color of the siding. Whites, off-whites, pastels, and other very light colors are good choices. When painting vinyl siding, be sure to follow all manufacturer instructions regarding surface preparation.
   

• Siding that has warped or buckled should be assessed by a siding or home repair contractor to determine the best remedy. The siding may have to be replaced.
   

• Oil-based coatings are not recommended on vinyl siding due to poor flexibility.
   

PRIMER

• A primer usually not needed when using an acrylic topcoat.
