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.
