To understand why the pattern may flake off, there must be a basic understanding of the
procedures involved in the printing of your pool liner. The print pattern is applied by a
process called "roto-gravure" printing. The inks used are solvent based and when applied to
the vinyl they actually bond themselves to the vinyl by "biting" into the it. Then a clear "top
coat" is applied to increase abrasion resistance and provide an added layer of UV protection.
The cause of ink flaking off the vinyl is low water PH. An acidic environment will weaken the
bond by softening the coating and eventually the ink. The more acidic the environment the
greater the likelihood of damage. The effect is cumulative and irreversible. Once this
softening occurs, the coating and ink are susceptible to abrasion and flaking.
Always keep your pool at the recommended PH of 7.4 to 7.8. Deviation from these levels
will adversely effect the performance of your liner.
