Overlap Liner Installation Notes
- Coping strips required: Overlap liners must be clamped at the top of the wall with coping strips (not a bead receiver track).
- Measure before ordering: Confirm your pool is truly 12 ft round and your wall height is 48″–52″.
- Base prep matters: Use a smooth, level base and remove stones/roots to reduce puncture risk and wrinkles.
- Consider a liner pad & cove: A floor pad and foam cove can help protect the liner and improve the finished fit.
Best For
- Replacing a worn, leaking, or faded liner on a 12′ round above-ground pool
- Pool owners who want an overlap install (no bead track needed)
- A simple, classic solid-blue appearance

Maintenance Tips
- Keep water chemistry balanced (especially pH, chlorine, and alkalinity) to help extend liner life.
- Avoid letting the pool sit empty—liners can shrink or shift without water support.
- Brush and vacuum regularly to reduce staining and keep debris from grinding into the liner floor.
- When winterizing, use a properly fitted cover and remove heavy debris to reduce stress on the liner and pool structure.
