Features
- MEASURE TWICE, BUY ONCE Whether installing for the first time, or replacing an existing liner, the Sunlight pattern offers durability while not breaking the bank. Be sure to check the measurements of your swimming pool to assure the correct size is purchased. Pool height is determined by measuring the outside wall from the ground to underneath the top rail. Round pool size is determined by measuring from the center point wall to wall in order to obtain the diameter.
- NO TROUBLE TO INSTALL - Overlap liners are draped over the walls of the pool. Once the bottom seam is even near the cove, the liner is ready to be secured. This material is held in place through the use of coping strips prior to putting the top rails back onto the pool. Bead receivers are not needed for this type of liner. Expandable pool liners have been designed to conform to above-ground swimming pools with dished-out middles and wall heights of 60. Will not work with Intex or Pop-Up pools.
- STAY COOL IN THE POOL Enjoy the warm weather while spending quality time with family and friends. Your backyard aboveground pool will surely become the place to be during those hot summer days. Stay cool in more ways than one with the Sunlight liner.
- HIGH QUALITY MATERIAL - Swim care-free knowing your liner can tough it out through abrasion, chemicals and UV fading thanks to the use of Lamiclear technology. The layers are made of an acrylic top coat, a UV resistant print layer, and a 100% virgin vinyl base. This material is then welded and cut for a flawless fit and finish. A 25-year limited warranty is included protecting against defects in material and workmanship.

Good quality, heavy liner. Lots of extra material hang over sides. Definitely needs several people, beer and pizza to install. πTip...Be sure to follow instalation video. We didn't wear shoes and had several dips in bottom from heels of our feet. Use the flat board taped to shoes? But overall item, beautiful liner. Held well for 3 years til pool sides rusted and buckled.

This is is a great pool liner, looks beautiful once installed. I had to purchase a new one because of a major sceptic tank issue, while the repair men jetted the drain lines an old drain line that was thought not connected was and the drain pipe was right at the edge of the pool liner and the jetter blew a hole straight thru the liner. It took a good 7 to 10 minutes of jetting before it ripped the liner so i think the liner is very durable to stand up against a commercial jetter. π
crazy situation , but I really like this liner and recommend it to other customers.

Perfect size and the material is great! My husband bought a different brand last time and it didn't last at all! This brand was our 1st replacement liner and this is the 2nd time we are buying this one. I'll only buy this liner from now on!

This was the easiest pool liner I have ever installed. I did this one by myself. First day I ground prep and put down black pool pad over the existing old liner. Second day, I followed instructions to unfold pool liner. Watched a guy on YouTube and I actually have water on the pool with no wrinkles. Pool is 29β round and 52β sides, liner has plenty of drop on outside. Still have to put the cap tops around the pool but you can see the pics.

We built a pool out of an old grain bin. I was worried that we were going to buy a custom liner and wait 8 months. Then I found this liner that had the EXACT dimensions we needed. 27 feet across by 60 inches tall!! And on top of that, the expandable (stretchy) fabric was manufactured to take into account that I had made the bottom of the pool into a cone shape to accommodate a drain! The price was amazing, the quality of material and the seams are great! Honestly, super happy with this! Now to fill up the pool!

First all let me say that this review should be going to the manufacturer (I hope it gets to "Smart Liners") not to the selling business. I have not installed the liner yet. This is only about the gasket kit. Please study the pictures carefully. 1. Return Fitting Gasket - Instructions say set of 3. I only received 1 2. Wide mouth skimmer Diagram Figure 1 - Clearly shows both sealing gaskets on the inside of the pool wall. 3. Skimmer Installation Step 2 & 3 - Align skimmer face and sealing gasket and fasten to outside exterior wall. This contradicts Diagram Figure 1. 4. Skimmer Installation - Step 3 & 4 Use 5/8" and 1" screws provided. No screws were provided. Read the instructions and check the diagrams. The instructions are useless unless you are experienced at skimmer installation and purchase the screws and return fitting gaskets yourself. 4. Skimmer Installation - Step
