Installing Liners


It is important to consider replacing all yellowed, damaged or questionable wall fittings, skimmers and face plates prior to liner replacement.  Also, it will be necessary to install new gaskets for all fittings, skimmers, lights, thermoplastic steps, main drain(s), etc.  Make sure to have these on hand before installation begins.


In order to secure an air tight fit when the liner is being set with an industrial vac, all interior seams where the walls are joined together (including steel stair sections) should be taped with duct tape.  It is recommended that all interior carriage bolt heads be duct taped as well (refer to picture below).


Installation Of Wall Foam

After taping the pool interior seams, wall foam may be applied to the walls and stairs covering roughness and providing a cushion for the liner.  (Just as padding provides a luxurious backing for carpeting.)  The wall foam comes in a roll 125 feet long, 42 inches wide and 3/16 of an inch thick.  It can be adhered to the walls with the use of a spray type adhesive.

Start out by inserting a broom handle in the corner of the rolls.  One person will guide the roll by leaning over the top of the wall, while another person inside the pool sprays the wall with the adhesive.  Each person can then smooth the foam on the steel panel.  Apply the adhesive per panel by spraying top, bottom and both sides of the panel first, then spray an X in the center of the panel. 

Apply the wall foam to the steel stairs in the same fashion as one would lay carpeting.  Place duct tape on all foam seams.

Coping and Extrusion

Most pool have concrete receptor coping with the liner track built into the coping.

Some pools have cantilever coping with the liner track built into the deck of the pool.

Some pools are designed for overlap liner installation, in which the liner is laid over the top of the pool walls and held in place by tacks, staples or a wooden plate.  You may want to update this to the more conventional beaded (or hung) method of installation by attaching a plastic extrusion to the walls.  This can be purchased for mounting to either the top or front of the pool wall.
