Once you have the framework set for your above ground pool, you must install the liner. The liner holds the water inside of the pool and helps secure the framework. Many people choose to install their own liners themselves rather than pay for a professional installation. Above ground pool liners come in beaded and over lap styles. Choose the correct liner for your pool's construction.
Install an Over Lap Liner
Remove the liner from the box and unfold it so that it lays flat next to the pool. Smooth out any major wrinkles with your hands.
Remove the top coping rail from around the pool.
Ask a family member or friend to help you position the liner inside of the pool. Line up the liner's seams with the framework of the walls. Walk around the pool and pull the liner over the pool's edge. Leave just enough liner in the center so that it barely touches the ground.
Replace sections of the coping over the liner that drapes over the pool's edge. Secure them just enough to keep the liner from slipping.
Add water into the pool with a garden hose or other water source. Loosen the coping gradually as the water begins to tug at the liner.
Continue filling with water and repositioning the coping sections around the circumference of the pool until the water level is at least 6 inches deep.
Check that the seams are still in line and fasten the coping securely over the top rail. Fill the pool with water to halfway up the skimmer.
Install a Beaded Liner
Remove the liner from the box and unfold it so that it lays flat next to the pool. Smooth out any major wrinkles with your hands.
Ask a family member or a friend to help you place the liner inside of the pool.
Grab the beaded edge and snap it into the liner retainer on the top edge of the pool wall. Continue along the circumference of the pool.
Use a garden hose or other water source to fill the pool with water.
Smooth out the wrinkles as you fill the pool.
