Symptoms
- Bubbles on the underside are flattened or popped
- Cover feels stiff, brittle, or is visibly discolored
- Tears or holes along the edges or surface
Likely causes
- CommonUV degradation from sun exposureSolar covers are designed to absorb sun but break down faster than opaque covers as a result.
- CommonChemical exposure, especially high chlorine levelsStrong chemical concentration at the surface accelerates plastic breakdown.
- PossiblePhysical wear from folding, rolling, or wind flappingRepeated handling stresses the seams and bubble structure over time.
What to do
- Inspect the extent of damage; a few small tears may be patchable, but widespread flattening means the cover has reached the end of its useful life.
- Patch small holes with a solar cover repair kit or waterproof pool tape as a temporary fix.
- Rinse and dry the cover before storing when not in use, ideally on a reel, to reduce UV and chemical exposure.
- Avoid adding shock or chlorine directly under the cover, since concentrated chemicals accelerate breakdown.
- Measure your pool accurately before ordering a replacement cover, accounting for any irregular shape or steps.
- Consider a slightly thicker or higher-quality solar cover for better durability if replacing due to frequent early wear.
