While you can certainly replace it, learning some basic pool liner repair techniques can put off replacement a year or two, saving you time and money in the process. Take your time to do it right, too, and you’ll find that your patience pays off.Here are the basic steps involved in fixing your pool liner:Recognize the leak. You’ll know you have a leak if your water level drops an inch or more in just a couple of days. Be sure to factor in usage, of course; if you’ve got a dozen 10 year-olds splashing around, you’re likely to lose that in a day.Identify the source. Once you’re sure there’s a leak, turn off the skimmer. Drop a couple of drops of food coloring into your pool water. If the food coloring sits in that spot and slowly disperses, move three or four feet away and repeat. Eventually, the food coloring should be drawn toward the leaky spot in your pool liner. You should mark the area and continue around the pool, identifying any other areas that may be leaking, as well.Clean the leak area. You don’t need to empty your pool to repair your pool liner. However, you want to get rid of any dirt an algae in the area or else your putty won’t stick. Prepare the pool liner repair putty.
This is a commercially-available product. It has two components: a resin and a hardening agent. Separate out a piece of resin big enough to patch the hole using a utility knife. Separate out an equal amount of hardening agent.Mix the two components and roll them into a ball. Stretch them and roll them until the colors are thoroughly mixed.Flatten and apply the putty. You want the putty to be about a quarter of an inch thick. Apply it to the side of the pool, and smooth it out, covering the entire hole or crack in question. Follow the putty maker’s recommendations as far as how soon it’s safe to use the pool again.That’s really all there is to it. Basic pool liner repair shouldn’t take you more than a few minutes; the most time-consuming portion is, in many cases, simply identifying where the leak is located in the first place.
