How to Paint Tempered Hardboard

Written by ryan lawrence | 13/05/2017

Tempered hardboard is a form of fiberboard. This engineered wood surface is often compared to particle board; however, it is much stronger and heavier than cheap particle board surfaces and tends to resist cracking and chipping much better. Paint won't permanently bond to bare tempered hardboard. To create a strong finish, you must apply a coat of bonding primer. If the hardboard is stained, it won't accept water-based primers. Be sure to choose the correct base, depending on the condition of the hardboard, or the finish will peel.

Things you need

  • Tack cloths

  • Professional painter's tape

  • Canvas dust sheet

  • Shellac primer

  • 2-to-4-inch natural-bristled paintbrush

  • Denatured alcohol

  • 2-to-4-inch polyester paintbrush

  • Gloss latex paint or acrylic enamel

  • Latex or acrylic primer (optional)

Wipe down the tempered hardboard with tack cloths.

Cover areas next to the hardboard, using tape. Use a low-tack painter's tape that will peel away without leaving adhesive residue.

Slide a dust sheet beneath the tempered hardboard. To prevent pooling and bleed-through, use a heavy-duty canvas dust sheet.

Coat the tempered hardboard with shellac primer, using a paintbrush with natural bristles. Shellac tends to run down vertical surfaces; be sure to smooth any drips before they have a chance to dry. Let the tempered hardboard dry for two hours.

Thoroughly rinse the paintbrush, using alcohol.

Coat the tempered hardboard with gloss latex paint or acrylic enamel, using a paintbrush equipped with polyester bristles. Smooth any flaws before they have a chance to dry. Let the tempered hardboard dry for two hours.
