Liner Protect 33

A high-tech liner that defies time and aggression

The result of extensive industrial research, the Protect 33 liner offers exceptional warranties. Resistant to water temperatures of up to 33°C, it is also less sensitive to chlorine, UV and fading than a traditional liner. Its unique resin, combined with a protective varnish, makes it undoubtedly one of the best liners on the market, acclaimed by the profession, and for a long time to come!

How to use

Clean your pool every week in season:

  • Clean the skimmer and the prefilter of the pump.
  • Use a non-abrasive, solvent-free waterline cleaner to clean it.
  • Clean the walls and bottom of the pool with a broom.
  • Backwash the filter for 15 minutes to avoid clogging.

Replace one third of the pool water every year to prevent saturation of the water with stabilisers.

Renew the filter media at least every 5 years.

Winterize when the water temperature is below 10°C using a winter cover to protect the liner from staining by dead leaves.

Combine different liner colours between the walls, bottom and steps of the pool.
