When lining our pool, we begin by sandblasting the interior and caulking it with silicone gel. The pool liner is composed of several layers, the first being a marine epoxy primer, which is coated around the entirety of the pool, both the interior and the exterior. We then spray-apply 2 layers of pure polyurea liner. We finish with an HP urethane clear coat colored finish. We also do multiple holiday finder tests, using an electric pulse to detect any weak areas in our liner and fix any we find with silicone gel.
Every step ensures a marine-grade seal. We typically look at a liner life expectancy of 8-12 years, taking into account the level of care, frequency of usage, maintenance of correct chemical balance, etc.
If you need your liner repaired or replaced after your warranty expires, you can order the necessary materials from us and we'll send them to you.
