Installation and Maintenance of
LUMAsite® sheets
Most varieties of LUMAsite® sheets, including Frost-SOS, are
acrylic panels reinforced with glass fibers that are cast into the panels
during manufacture. Some varieties have a micro-grain gloss finish on both
sides. Other varieties have a micro-grain gloss finish on one side, and a
cast-in satin finish on the other (these varieties are denoted by an SOS
suffix).
Protect the surfaces during fabrication. Sheets up to .125" thickness are
readily cut using a power-shear capable of cutting 10 gauge mild steel.
Saw-cutting is readily accomplished using abrasive blades of the kind used
to cut masonry. Use a relatively slow feed rate. (Although carbide-toothed
circular blades can be used for small cutting jobs, the blade will dull
quickly and may overheat.)
Use a high-speed twist drill (or hole saw for larger holes) to drill
LUMAsite® sheets. Clamp the sheet to a firm backing for drilling. Use water
if necessary to cool the drill (dip the drill tip into a cup of water). Wear
eye protection when using power tools. Wear a dust mask if necessary to
avoid breathing the saw dust. Refer to the MSDS for other important safety
information.
LUMAsite® sheets are ordinarily installed by mechanically fastening them in
place.
Pre-drill slightly oversize holes for fasteners. Use metal fasteners, with
bonded (metal/rubber) washers to fasten panels in place. In vertical
applications, hang the panel first (install fasteners adjacent to the top
edge, but no closer than ½" from the edge) such that the panel is not
resting on the bottom edge. Then install remaining fasteners working from
top to bottom. Most sealants, including silicone varieties, work
satisfactorily. For outdoor applications, acrylic foam tape is recommended
under joints and fastener lines.
LUMAsite® sheets are often used (usually in .090" or .125" thickness) as
lighting diffuser panels, installed in a T-bar grid. Refer to the Lighting
Specification page, which includes guidelines for panel sizes and
thicknesses.
Maintenance of LUMAsite® sheets after installation primarily involves
cleaning the surfaces of the material. Most dirt and soiling are readily
removed using a non-abrasive soap and water applied with a sponge or soft
brush, then rinsing. Do not use abrasive soaps or polishes. Note that using
abrasive cleaners on the surface can change the reflectivity (making a shiny
spot on the satin surface, for example), and can otherwise scratch the
surfaces.
Note that LUMAsite® sheets are acrylic-based materials, and some solvents
will damage the surface. Do not use chlorinated solvents, paint removers,
lacquer thinner, acetone or methyl ethyl ketone. To remove marker, crayon
and some paints from LUMAsite® sheets, rubbing alcohol or mineral spirits
can be used (with adequate ventilation and awareness of flammability). “Soft
Scrub” cleaner can also be used on LUMAsite® sheets.
