Thick vinyl is the material most frequently used for above ground pool liners. These liners are what keeps the water in the pool. The water in an above ground pool pushes against the vinyl liner and keeps the pool’s walls upright. The steel supports for your above ground pool will fall inward when the water is taken out of the pool liner.

Above ground pool liners serve a vital function, but they can be stylish too. They can be purchased in a large selection of styles and can set the tone for your entire pool area. Above ground pool liners are available in a wide array of thicknesses which can be called grades.

When you buy a thicker vinyl pool liner it is stronger and more last for a few years when subjected to regular use. The thickness is referred to either as mil or gauge when ordering a pool liner. Included with most above ground pools is a 20 gauge vinyl liner. When buying a replacement liner you can upgrade the thickness to 30 gauge if you would like. Above ground swimming pools will need either an overlap or a beaded pool liner.

Different strategies are used to hold each of these liners in effect. The overlap style of pool liner should be folded ott of the pool and fixed in place beneath the top rail. If you look under the top rail you’ll see a tiny portion of the pool liner. You have to take off the top rail around your pool in order to install a replacement liner for an overlap style pool. You want to use plastic clips to hold the liner in place till you replace the top rails. With a beaded pool liner there’ll be a small groove, or bead, along the top edge. You install the pool liner by placing the bead along a track which runs along the pool at the head of the pool wall. You’ll be able to find the track for the beaded pool liner if you look underneath the top rail inside the pool.
