Installation Notes
- Inspect the pool floor and walls; remove sharp debris and ensure the sand base is smooth before installing.
- Use a proper liner pad and pool cove to protect the vinyl and prevent shifting.
- Center the liner and drape over the walls; fill slowly and smooth wrinkles as water rises for the cleanest finish.
- Avoid installing in cold temperatures; sunshine helps the vinyl stretch for a better fit.
PRO TIP
Measure twice. Liners are best confirmed by exact pool size and track type.
For Overlap liners, ensure your coping strips are in good condition to securely lock the liner over the top of the pool wall.
Color/pattern may vary slightly by production run and lighting. Always verify pool measurements and liner type before opening packaging.
