Usage and Fabricaon 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 illustraon 3). High feed and
drilling speeds may hinder the efficiency of the drill by creang heat buildup. For best
results, use sharp bits and lower speeds.
Roung and Milling Foam may be sloed, beveled, rabbeted, etc. with routers or shapers commonly used
for working wood. Carbide pped cuers are preferred.
SURFACE TEREATMENT Foam is a versale material suitable for a variety of graphic applicaons ranging
from signs to POP displays. Below are some helpful hints on how to prepare and use
Foam for prinng, painng, gluing, photo mounng and laminang.
Surface Preparaon It is always a good pracce 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 Prinng Foam has a consistent and smooth surface that lends itself to the permanent
acceptance and retenon of a variety of prinng inks. One of the most commonly used
methods screen prinng. Follow the surface preparaon instrucons. It is always a good
pracce to test print before going into full producon.
Note:
Mixing different brands of prinng inks and solvents may reduce the longevity of the
sign. A telltale indicaon 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.
