Guidelines for Jobsite Storage and Removal of PREGIS PolyMask Protec�ve Films

Jobsite storage of panels with PREGIS PolyMask protec�ve ﬁlms applied

Stored panels should be protected from exposure to moisture, sunlight and precipita�on. It is recommended to store panels indoors, for the utmost protec�on from environmental condi�ons. If outdoor storage is the only means, it is recommended to store panels elevated under a water-proof tarp and �lted in such a way to not entrap moisture and facilitate drainage.

Best prac�ce techniques for the removal of PREGIS PolyMask protec�ve ﬁlms from panels

Protec�ve ﬁlms should be removed gradually beginning at one end peeling back at a 180°degree angle with a smooth even mo�on. Do not quickly jerk the protec�ve ﬁlm from the panel. Inspect panels for any adhesive residue once the protec�ve ﬁlm is removed.
Contact your supervisor immediately if residue is observed. (See Technical Bulle�n: “Guidelines for UV Exposed Protec�ve Film” for residue removal techniques)

When removing the ﬁlm in cold weather condi�ons it is not suggested to remove the protec�ve ﬁlms if the panels are frozen. If frozen, bring panels into an indoor environment to return them to a recommended ﬁlm removal temperature. When removing ﬁlm from panels, the temperature should be between 40° F (16° C) and 90° F (32° C) following the best prac�ce ﬁlm removal techniques stated above.

When removing the ﬁlm in wet weather condi�ons it is not suggested to remove the protec�ve ﬁlms if the panels are wet and saturated with moisture. If wet, bring panels into an indoor environment and allow them to dry before removing ﬁlm following the best prac�ce removal techniques stated above.

In both weather condi�ons using sunlight to dry and or bring panels to the recommended ﬁlm removal temperature can create a UV exposed residue condi�on. (See Technical Bulle�n: “Guidelines for UV Exposed Protec�ve Film” for residue removal techniques)
