DIY Above Ground Pool Liner Installation

With summer arriving, setting up an above ground pool can be an enjoyable activity. Choosing the right liner is essential for a successful installation. While it may seem intimidating initially, having the correct tools and supplies makes the process straightforward and fun. Replacing or installing an above-ground pool liner can be completed over a weekend, saving money on professional installation. Proper measurement, purchase, and careful installation are key to a smooth experience.

Follow these step-by-step instructions to install your own above ground pool liner.

Drain the Pool
Use a high-capacity pump to remove most of the water. When the pool is nearly empty, cut the liner at the base with a utility knife. Continue pumping out residual water until completely drained.

Remove the Old Liner
After draining, cut the existing liner into sections with a razor knife. Roll them up and slide them over the pool wall. For overlap liners, release the top rails as per your manual before removing the liner.

Prepare the pool base by smoothing out any dips, waves, or uneven spots, especially if it has a sand bottom. Consider adding fresh sand for a smooth surface.

Install the New Liner
Choose a warm day for installing, ideally between 65°F and 75°F, to help the liner stretch easily. Different liner types, such as overlap or beaded, require specific procedures. Follow manufacturer instructions carefully.

Set the Liner
An optional step involves using a vacuum pump to remove wrinkles. Seal wall returns with duct tape and a cardboard patch to ensure a tight fit.

Fill the Pool
Reassemble the top rails before filling. Watch for wrinkles or uneven surfaces, especially on overlap liners. Fill slowly to allow the liner to settle, maintaining smoothness on the floor.
