Installation Guide

Sealant
After the
sheets are installed and the protective masking is removed,
points where the sheet meets the building’s exterior walls may be
sealed with a thin bead of 100% silicone sealant. Always check the
product label to ensure sheet compatibility.
Note: When using H and U-proles a continuous bead of sealant is not
required between each sheet.
Cleaning
Periodically cleaning in accordance with guidelines can help prolong the life of the sheets. Use
of incompatible cleaning products can cause structural and/or surface damage. Normal dust and
dirt accumulation is washed off by the rain. Regular rinsing of sheets with clean lukewarm water is
sufficient in dry areas.
• Never use abrasive cleaners, corrosive chemicals, or gasoline.
• Never scrub with brushes, steel wool, or other abrasive materials.
• Don’t use squeegees, razorblades, or other sharp instruments to
remove deposits or spots.
• Don’t clean multiwall polycarbonate sheets in direct sunlight or at
high temperatures.
Manual Cleaning – Ideal for Small Areas
• Gently wash sheet with mild household detergent, lukewarm water, and a soft cloth or sponge.
• Thoroughly rinse sheet with clean water and dry with a soft cloth to prevent water spotting.
Automated Cleaning – Ideal for Large Areas
• Use a high-pressure water cleaner (max. 100bar or 1,450psi).
• Always test a small area of the sheet before using a pressure cleaner.
• Use of additives to the water should be avoided.
Note: A good grade of Fels-Naptha or isopropyl alcohol may be used to remove fresh paint or grease.
Rub lightly with a soft cloth. Afterwards, wash using mild soap and lukewarm water. Rinse thoroughly.
