It is a good idea to install your new swimming pool liner for your inground or above ground pool on a hot day, 70 degrees or greater. The hotter it is, the easy it is to work with the virgin vinyl material of your swimming pool liner.
Never install your swimming pool liner on a cold, windy day, 70 degrees or less. It is an excellent idea to hire a professional pool liner installer to do the job. It can save you the hassle of needing a replacement pool liner down the road from inadequate installation.
