First of all, the installation of the pool liner should be done properly step by step. In the case of wrinkles, the water should be drained and wrinkles can be done with hands. Wrinkles don’t give a good appearance to the pool and might cause little injuries to your feet. The setting up of vinyl can be slowly done and the strips or screws can be set again on a sunny day, as it will work best when warm. It is always recommended to start from the center and move towards the walls.
