Workbench top. Cover the old dirty one with a brandnew surface. Also, outdoor signs if coated properly.
yes. I painted some eucaboard, but used primer first
Eucaboard is not inherently flame retardant. However, it can be treated with fire-retardant chemicals to improve its fire resistance properties.
Like any manufactured wood it suggest a protective finish. Eucaboard is a lesser known HDFB, (high density fiber board) its made from the Eucalyptus tree by the manufacture Eucatex, in Brazil. The American counterpart is Hardboard or the brand name Masonite. There are several types and sizes. Answer: poorly, I would suggest a Vinyl sealer (2 coats) with a Polyurethane top coat (2 to 3 coats).
To cut eucaboard, first, measure and mark your desired dimensions using a straight edge. Use a sharp utility knife or a fine-toothed saw to make the cut, applying firm, even pressure. If using a utility knife, score along the marked line several times before snapping the board along the cut. Always wear safety gear, such as gloves and goggles, to protect yourself while cutting.
