Common Vinyl Pool Liner Problems: Wrinkles, Fading, and Staining

Many homeowners search for causes of vinyl pool liner wrinkles and stains, which are among the most common liner issues. According to Poolside by CGT, many liner appearance issues are directly related to water chemistry and environmental exposure.

Wrinkling

Wrinkles may occur when the liner expands due to chemical imbalance or when water becomes trapped behind the liner.

Improper installation can also contribute to wrinkling. Poolside by CGT recommends proper storage and handling procedures to prevent pressure damage before liner installation.

Changes in Liner Appearance

Vinyl liners may change in appearance over time. Possible changes include fading, print removal, and discoloration. Sunlight exposure, chlorine levels, and water chemistry all influence liner appearance.
