A sandblasted sign is a beautiful, functional addition to any office front or professional environment. Because of the advantages, sandblasted signs are primarily made from High Density Urethane, although Redwood and Cedar are still common.

"HDU" is short for high-density urethane foam. It is a material expressly designed for the sign industry. Unlike other foam with which you may have experience, HDU consists of more solid and less air.

Urethane is a specialized material that it is unaffected by all petroleum-based solvents. Even in its "raw" state, it is completely waterproof and unaffected by temperature and climate. A HDU sandblasted sign is impervious to water. Water and moisture cannot get under the finish and cause material break down.

HDU sign foam, unfinished is warranted for 10 years, indoor or out, against deterioration, warping, and cracking. It is 100% waterproof, not affected by temperature, and will not rot or decompose.

HDU sign foam can be blasted with 2 patterns:

• Simulated Wood Grain
• Sandstone or Pebble Finish

Advantages of HDU Sign Foam:

Sign Foam will not warp, crack, or bow like solid wood when exposed to the elements. It is slightly lighter than wood, which might be a consideration when hanging a sign, and the lighter weight saves in shipping.

Sign foam can be blasted with a simulated wood grain finish that, in most cases, looks better than a real wood grain.
