Storage

ACRYLITE® Soundstop noise barrier panels are shipped on pallets packaged in polyethylene film overwrap that protects the sheet from dirt and moisture. The overwrap should be left intact during storage to protect the panels. Pallets may be stacked to maximize storage space. If various sizes are stacked horizontally, place larger panels at the bottom to avoid unsupported overhang.

These panels are supplied with a protective polyethylene masking on both surfaces. Masked panels must NOT be stored in direct sunlight for prolonged periods of time. Prolonged exposure to direct sunlight may make the masking brittle which can cause the masking to tear upon removal.

They should not be stored near radiators, steam pipes, or other heat sources, as exposure to excessive heat may soften and deform the panels. Do not store panels near or expose them to solvent vapors that may penetrate the masking and damage the panels’ surface.

Removing Masking

The panel masking should be left in place during most fabrication and installation operations to protect the panel surface. During installation, roll back masking from the edge to avoid engagement in glazing channels. To remove stubborn masking use only plastic putty knives/scrapers while being careful not to mar the panels surface.

Cleaning

As a result of the production process, ACRYLITE® Soundstop noise barrier panels have a smooth, non-porous surface that is retained even after long-term outdoor exposure. Dirt will not readily adhere to this polished surface, as a result, rain or dew that frequently forms at night, will rinse the sheet clean.

In most cases,these panels need no additional cleaning. Should special circumstances make it desirable to clean the panels, cleaning is best accomplished with water using a high-pressure washer. Grease, oil, or tar may be removed with a good grade of hexane, aliphatic naphtha, or kerosene. These solvents may be obtained at a paint or hardware store and should be used in accordance with manufacturer’s recommendations.

WARNING

DO NOT USE: window cleaning sprays, kitchen scouring compounds, or solvents such as acetone, gasoline, benzene, alcohol, carbon tetrachloride, or lacquer thinner. These can permanently damage the panel’s surface and/or weaken the panel causing small surface cracks, called “crazing”.

Removing Scratches

Fine scratches can be removed by hand polishing. Apply a plastic scratch remover such as NOVUS 2 to a soft flannel pad and rub in a circular motion. When the scratches have disappeared, remove all residue and polish. For deeper scratches, first wet sand lightly with 400 grit “wet or dry” sandpaper, using plenty of water and rinsing the sandpaper frequently. Repeat with 600 grit “wet or dry” then 800 grit “wet of dry” sandpaper then buff with a clean cotton or flannel covering on a rotary buffer and a good automotive grade rubbing compound.

Graffiti Removal

Graffiti can be removed from the panels using a graffiti remover recommended below. Although there are many graffiti removers deemed safe by the manufacturer for use on plastics, plastics is a general term and the majority of these removers contain aggressive solvents that can cause damage to the panels.

Though procedures may vary by product, basic steps to remove graffiti are as follows: Clean the surface with a non-abrasive rag. Spray the remover on the graffiti area. Allow the remover to soak for 2 to 5 minutes, then rinse off with a high-pressure water spray or wipe away with soft (non-abrasive) towels. Note that while pressure washing is the fastest removal method it may not be allowed in all jurisdictions as the removed paint enters the environment. In some cases, such as when the temperature is below 55°F, a second application or agitation of the graffiti with a clean soft cloth may be required to remove all of the graffiti. Follow final removal with a water rinse and squeegee to remove traces of graffiti remover which otherwise leave an oily residue and contribute to dirt accumulation.

The pictures below are of ACRYLITE® Soundstop noise barrier panels that were defaced or “tagged” with a solvent-based acrylic modified resin spray paint and then cleaned with Disappear Organic Graffiti / Adhesive Remover. For this test, the remover was sprayed on the graffiti and allowed to soak for 5 minutes prior to spraying with a 2300 psi pressure wash. The paint was allowed to cure 25 days prior to removal.
