PERM-A-BARRIER® VPL50RS UV Stable can be applied if the ambient temp is 10° F(-12° C) and rising. It is recommended to store PERM-A-BARRIER® VPL50RS at 50° F(10° C) for a minimum of 24 hours prior to and during installation. This can be maintained during the spray application using 5 gallon pail blanket heaters.
When the installation of PERM-A-BARRIER® VPL 50 RS UV Stable is expected to be below 50° F(10° C) a high pressure pump with a minimum of 4000 psi (275.79 bar, 220 volt) is recommended.
If a low pressure pump is being used (2500psi/172 bar, 110 volt) it is recommended to keep the material consistently above 50° F(10° C) for a smooth spraying experience. This can be achieved by ensuring the hose is insulated and/or heated while spraying. Hose length should not exceed 50’ in length and a minimum 3/8’ diameter with a 3’ 1/4“whip hose. If poor spray pattern (Fingering - finger spray pattern) is observed increase hose diameter to ½’ and whip hose diameter to 3/8’.
For any questions, please contact your local GCP Technical Service Representative.
Read the product SDS and follow manufacturer's instructions for pail and hose heaters as PERM-A-BARRIER® VPL50RS UV Stable contains a small amount of solvent.
