# Precision Board

HDU

**Precision Board Plus HDU Sign Board**is typically used in applications requiring greater structural integrity than products made of expanded polystyrene, as HDU foam board has greater compressive, tensile and shear strength, as well as greater long-term dimensional stability. HDU is commonly used in outdoor dimensional signage for carved or routed signs, usually as a substitute for wood. **Precision Board Plus HDU Sign Board** blocks and sheets can be bonded into the general shape of your sign or sculpture to get you closer to your final shape, saving time and material.

**Typical Uses:**

- Dimensional Signs
- Monument Signs
- Sandblasted Signs
- Faux Wood Signs
- Routed Signs

### Companion Products

- **FSC-88 WB** : FSC-88 WB is a sprayable, brushable, rollable water based primer and filler that is used to fill and smooth Precision Board Plus HDU prior to finishing with paints and coatings. Use FSC-88 WB when a smooth surface is desired, or as a primer to ensure paint adhesion.
- **PB Bond-240** : PB Bond-240 HDU Adhesive is an amber colored, *one part, urethane adhesive* that works well for indoor or outdoor applications. It cures from a liquid to a solid state with a slight amount of moisture.
