Usage and Fabrication Guidelines
Drilling Holes Holes may be drilled through Foam using the same methods employed
for drilling wood. Carbide tipped drills are recommended with a point
angle between 90 degrees and 110 degrees and with a spiral angle of 30
degrees. (see illustration 3). High feed and drilling speeds may hinder
the efficiency of the drill by creating heat buildup. For best results, use
sharp bits and lower speeds.
Routing and Milling Foam may be slotted, beveled, rabbeted, etc. with routers or shapers
commonly used for working wood. Carbide tipped cutters are preferred.
SURFACE TEREATMENT Foam is a versatile material suitable for a variety of graphic
applications ranging from signs to POP displays. Below are some helpful
hints on how to prepare and use Foam for printing, painting, gluing,
photo mounting and laminating.
Surface Preparation It is always a good practice to clean the surface of the material to
eliminate the possibility of any grease or dirt that may have
contaminated the surface during handling. For best results, use
Isopropyl alcohol or naphtha and clean lint-free cloth to wipe the
surface. Avoid using paint thinners because they leave a residue on the
surface that could interfere with the bonding of the paints, inks and
adhesives.
Screen Printing Foam has a consistent and smooth surface that lends itself to the
permanent acceptance and retention of a variety of printing inks. One
of the most commonly used methods screen printing. Follow the
surface preparation instructions. It is always a good practice to test print
before going into full production.
Note:
Mixing different brands of printing inks and solvents may reduce the
longevity of the sign. A telltale indication is the premature cracking of
the surface which is difficult to determine when first printed.
Scratches and dents will become accentuated when screen printed.
Sanding down the affected area with a very fine sandpaper or using a
