Usage and Fabricaon Guidelines
Drilling Holes Holes may be drilled through Foam using the same methods employed for drilling
wood. Carbide pped drills are recommended with a point angle between 90 degrees
and 110 degrees and with a spiral angle of 30 degrees. (see illustraon 3). High feed and
drilling speeds may hinder the efficiency of the drill by creang heat buildup. For best
results, use sharp bits and lower speeds.
Roung and Milling Foam may be sloed, beveled, rabbeted, etc. with routers or shapers commonly used
for working wood. Carbide pped cuers are preferred.
SURFACE TEREATMENT Foam is a versale material suitable for a variety of graphic applicaons ranging
from signs to POP displays. Below are some helpful hints on how to prepare and use
Foam for prinng, painng, gluing, photo mounng and laminang.
Surface Preparaon It is always a good pracce 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 Prinng Foam has a consistent and smooth surface that lends itself to the permanent
acceptance and retenon of a variety of prinng inks. One of the most commonly used
methods screen prinng. Follow the surface preparaon instrucons. It is always a good
pracce to test print before going into full producon.
Note:
Mixing different brands of prinng inks and solvents may reduce the longevity of the
sign. A telltale indicaon 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 blow type heat gun is recommended
to reduce the change of the scratch showing through the ink. Please refer to Table 1 for
a list of pre-approved ink manufactures.
