What type of finish?

King StarBoard® ST has a textured, low-gloss finish on both sides of the sheet.

How can the material be fabricated and finished?

Use standard woodworking tools: table saws, table routers, drills, blades and bits. Carbide router bits with two to four flutes are recommended.

How to clean and maintain?

To clean everyday dirt and stains, use either Mr. Clean Magic Eraser, Soft Scrub® or Simple Green Concentrate at full strength with a nylon scrubby or stiff nylon brush. Scrub lightly; excess force can mar the finish. Persistent stains will usually go away if you soak the area with bleach. Do not use 100% chlorine used to treat swimming pools.

Can I use glue or paint?

Gluing is not recommended. Because King StarBoard® ST sheet products are designed to resist water and grime, they cannot be painted and the use of adhesives is not recommended. It is preferable to mechanically fasten or weld. Specialized welding equipment and rods, designed for use with polymer sheets, are available.
