| Vinyl Siding Warp: Warping or buckling of vinyl
siding panels that have been repainted.
Possible Cause:
Most likely cause is that vinyl siding was repainted with a
darker color paint than the original color. Dark paint tends to absorb the beat
of the sun, transferring it to the substrate. When vinyl siding expands
dramatically, it is not able to contract to its original dimensions.
Solution: Paint vinyl siding in a shade no darker than the original.
Whites, off-whites, pastels and other very light colors are good choices. 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.
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.
