Smartline 18 ft x 38 ft Oval Swimming Pool Liner | Boulder Swirl | Overlap Style | 48-52 Inch Wall Height | 25 Gauge Heavy Duty Virgin Vinyl | Designed for Steel Sided Above Ground Pools

✓MEASURE TWICE, BUY ONCE – Whether installing for the first time, or replacing an existing liner, the Boulder Swirl 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. Oval pool size is determined by measuring from the center point across the longest and widest ends.
✓PRETTY PLEASING PATTERN - The Boulder Swirl liner print provides a shimmering cool appearance to any swimming pool. The North American cut material is hand-folded to prevent permanent creasing and excess wrinkling. Before installing, lay the liner out in the sun for a minimum of one hour to warm up the vinyl ensuring it is able to stretch when adding water. The best temperatures to install would be between 70-80 degrees.
✓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 above ground pool will surely become the place to be during those hot summer days. Stay cool in more ways than one with the Boulder Swirl liner.
✓HIGH QUALITY MATERIAL - Swim carefree 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.
