Proper Care Ensures Long Life for Vinyl Pool Liners

Homeowners with backyard swimming pools depend on vinyl
pool liners to keep their pools looking beautiful season after
season. Nearly 70 percent of the residential pools in the United
States rely on durable and easy-to-clean printed flexible vinyl to
protect the interior pool surface from environmental elements
and manmade conditions.

From sunlight and temperature fluctuation to chemicals and
careless cleaning, this surface is exposed to numerous hazards.
The most common causes of damage to vinyl pool liners are
premature pattern wear due to abrasive cleaning tools and
bleaching due to improper chemical balance. These two factors,
exclusively or in combination, can attack the vinyl liner and
cause premature aging.

If you're one of the five million North American homeowners
fortunate enough to have a pool with a vinyl liner, follow these
simple tips to lengthen its years of service:

Chemical Maintenance


  • Prior to installation, read and follow the chemical manufacturers'
    directions. Many liner problems are a result of misuse of chemicals.
  • When adding chemicals, add one chemical at a time.  
  • Add each dissolved chemical through the skimmer for best
    dispersion into the pool (through the filtration system).
  • Allow each chemical to circulate throughout the pool before adding a
    second chemical. Certain combinations of chemicals at a high
    concentration can cause bleaching of the liner. You should test for
    the presence of dissolved metals, because they may directly stain the
    vinyl liner or combine with calcium hardness to form discolored
    deposits.
  • Maintain proper water balance: pH in the range of 7.2 to 7.6; total
    alkalinity at 80 ppm to 100 ppm; and calcium hardness at 200 ppm to
    300 ppm.
  • Keep free chlorine, the most common active ingredient that sanitizes
    the pool, at 1.5 ppm to 2.5 ppm. If the concentration drifts below 1.5
    ppm, algae and bacterial growth can take hold more easily and may
    cause staining of the vinyl liner. If the active chlorine concentration is
    maintained greater than 2.5 ppm, liner wrinkling may occur. This
    problem can be further aggravated if accompanied by pH levels that
    fall below 7.0.
  • All vinyl pools must be routinely stabilized with cyanuric acid in a
    range between 25 ppm and 100 ppm. A level of less than 25 ppm
    combined with a pH level of less than 7.0 can cause the liner to form
    wrinkles. Avoid using hydrochloric (muriatic) acid for pH adjustment
    because it will chemically attack the liner's print pattern. Use
    hydrochloric acid for total alkalinity reduction only, since much of the
    acid is consumed in the process.



Seasonal Care

  • Avoid the use of any abrasive cleaning agents or cleaning aids.
  • Vacuum and clean the pool with a cleaner designed for vinyl lined
    pools.
  • Never use sharp objects in or around the pool, as they can puncture
    the liner.
  • After the chemicals have dissipated, cover your pool when it's not in
    use. This will decrease its exposure to damaging ultraviolet rays.
    Less chemicals are required if your pool is covered and/or not used.
    To avoid high concentrations of airborne chemicals building up
    between the water and the cover, open or vent the cover every 24
    hours.
  • Do not drain the pool completely for any reason without consulting a
    pool professional. The older the liner, the higher the risk that it will
    shrink and not stretch back into its original shape.
  • Never close a pool without circulating the pool water for several
    hours after the addition of chemicals.
  • Pool ladders, make sure the rubber bumpers that protect the ends of
    the ladder from the vinyl liner are always used. Never allow the use of
    a ladder in your pool that does not have both rubber bumpers firmly
    in place. If the bumpers are lost or worn through, then the ladder will
    cut the liner. Do not use the ladder, or remove the ladder from the
    pool, until you have new bumpers on the ladder.
  • Clean the vinyl liner at the water line of all residue and scum that will
    accumulate as a result of people using the pool and all substances
    floating at the surface of the water like suntan oil, dust, dirt etc. Take
    special care to clean any area at the water surface where the sun hits
    directly for a long period of the day. DO NOT USE ABRASIVE PADS
    OR ANY CLEANER THAT IS ABRASIVE. Use a dealer-approved vinyl
    cleaner and apply it with a sponge.
  • Suntan oil badly stains vinyl due to iodine and other caustic
    chemicals it contains. Without proper removal, these chemicals will
    become baked on by the sun and will eat away the finish of the vinyl.
    Ultimately, the stains will degrade the vinyl, causing it to crack and
    break. The combination of sunshine, pool chlorine and suntan oil is
    fatal to vinyl.
