Hardboard is a tough smooth panel made with wood fibers compressed under high pressure and heat. We carry different thicknesses in both Standard grade and Tempered grade.


Standard grade hardboard is a medium brown panel, smooth one side with a rough crosshatch pattern on the other.

Tempered grade hardboard is impregnated under heat with linseed oil, making it tougher than Standard grade and rendering it more moisture resistant. Tempered hardboard is dark brown in color and smooth both sides.

Standard hardboard receives paint well and is used as underlayment, wall panels, backer boards, in furniture and cabinetmaking and as sacrificial work surfaces. Artists often use hardboard as a canvas.

Tempered hardboard is used when a tougher surfaces required when both surfaces need to be smooth and in high moisture areas.
