Most people don’t give a lot of thought to vinyl pool liners which is rather unfortunate. You wouldn’t buy a new car without understanding its features, warranty, gas mileage, etc., so why would you purchase a pool or replace a liner without being educated on the product as well?
The wall material and pool floor are both made up of a vinyl membrane that is typically made to custom fit the pool. There are various styles available such as overlap, beaded, J-hook and expandable for above ground but beaded is the only option for in-ground vinyl pool liners.
The walls of the pool are generally made from thermoplastic or galvanized steel and secured together to create the perimeter of the pool. These sturdy materials also offer support to the liner so it doesn’t cave from the weight of the water. Due to the structural designs, those that use vinyl pool liners are often limited in their shape.
In Ground Installation
Before embarking on an entire replacement, you may want to consider repairing or resetting your liner first. If these options don’t work, a replacement will be needed. Replacing in ground vinyl pool liners is a project that will take every bit of a full day and a few helping hands.
Precise measurements are crucial and understand that a new liner will often take up to three weeks to receive so don’t wait until the beginning of summer when you want the pool open to place your order. The pool will have to be completely emptied and the old liner will need to be removed (and recycled). Any imperfections like rust will need to be sanded, wall joints need taping and you should foam all walls that are corroded or pitted to ensure a smooth outcome. Face plates get removed and the track gets inspected for any needed repairs.
Once the walls and floor are prepped, the liner can be placed in and locked in track. You will need to use a vacuum to smooth out wrinkles and plates are cut out once the liner is set.
Above Ground Installation
Installing above ground vinyl pool liners will require the help of a few people as well. To remove the existing liner, you will need to remove U channels and screws holding it in place. After this is done, apply foam to any rust or weakened areas and replace all sand that you find contaminated with algae.
When you drape the new liner over the pool, make sure that there are no twists in it and secure it in place using U channels. Some people need to use a shop vac to remove air between the wall and the liner, others don’t. The most important thing is to just make sure that you have all the slack that you need to stretch the liner into place.
You should watch vinyl pool liners closely when you are filling them. If you simply turn on the hose and leave it alone, there is a very good chance you will come back to some serious wrinkles. This would require you emptying the water so you can start all over again which is not something anyone wants to do!
