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.
- NO TROUBLE TO INSTALL - Overlap liners are draped over the walls of the pool during the installation process. 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. The liner is made to work with pools which have a flat bottom and wall heights of 48" or 52". ***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.

his is the best pool liner I’ve ever used! Replacing my old liner with this one was so much easier than my previous installation. The fit was perfect, and the whole process went smoothly. I also highly recommend using Styrofoam wedges at the base of the pool — they make a huge difference in both comfort and appearance. Couldn’t be happier with the results!

Pool liner is beautiful! Pool guy came and put it in today and said that this brand will fade quickly with a chlorine pool, even though it advertises on fading. Seems to be a good fit. Gave three stars for now. When it fills and I have no leaks I will come back and re rate. Above is my first review we have since installed all is well

Perfect replacement. Vinyl is heavy but flexible. Easy to install. Color is great and uniform on the entire liner. Great value, compared to local pool stores.

Before i leave a review I always try to deal with seller and or manufacturer before review is left. Purchased last august and had my installers drained my pool and remove the old liner, during installation we found the center seams not be boned correctly leaving a 1/2-to-3/4-inch flap for lack of a better term. As my pool installers had already started, we installed and notified seller. Nothing happened. This year upon opening found the seam is somewhat worse and contacted seller and emailed & text seller which they did respond after a few tries. Found a small leak in the seam loosing 1/2 every day or so. (fixed for now) My review is not about the offer to replace which we did not except but to give a heads up before purchasing the product If you check the reviews other buyers have had similar problems. I included some picture showing the seam with dirt trapped under the lifted areas. I hand vac my pool now as i am afraid to use my robot vac in fear of it tearing the seam.

Great liner. The only problem was user error. Hubby didn’t completely center it, so the rocks are not level. But, as far as liners go- went down easy and is smooth. Must follow directions! Watch YouTube videos, if you don’t know what you are doing. Plenty thick… I was worried it would be too thin and easy to tear, but so far, it is great!

This pool liner looks great and is of great quality! It was just installed this past June, and we received compliments all summer. It also shipped very quickly and in good condition.

Worked great. 21’ round above ground pool. I selected the 54” high want to make sure I had plenty to work with. Once pool is full and liner has stretched all she can then you can trim any excess off. I wanted a few days. I got the 25 gage and although works great it’s worth the extra money to go a little thicker and purchase the 30 gage. Use your leaf blower to push wrinkles across floor and you will be amazed. Good luck
