Masonite is a hardwood siding made from wood, wax and resins placed under extreme heat and pressure. Although it is considered durable, like other types of siding it is subject to dings, dents and damaged spots over the years. It is important to replace Masonite boards once moisture gains access to the interior wall behind the siding. Leaks can cause deterioration of the wooden framework of the home and damage drywall or paneling.
Things You'll Need
- Safety glasses
- Measuring tape
- Utility knife
- Pry bar
- Claw hammer
- Reciprocating saw
Measure the length of damaged clapboard. Widen the measurement so that each end meets with the nearest wall stud. Mark the end points with a pen or marker.
Run a sharp utility knife over the mark to cut the board all the way through. Be careful not to score the boards directly above or below the damaged one.
Use a small pry bar to wiggle the good clapboard loose that lies directly above the damaged one. Remove the nails that hold the top clapboard to the damaged one with the claw end of a hammer. Leave the top nails loose, but intact. The good clapboard can be pushed back and fastened into position once the damaged board is replaced.
Separate the damaged board from the clapboard beneath with the pry bar. Place a rag over the lower board to avoid damaging it.
Fit a reciprocating saw in behind the damaged clapboard and cut through the nails holding it in place. Gently pull the board free by hand.
Tips & Warnings
- Use caution when applying pressure to the nails during removal. Masonite siding boards damage easily.
- Wear safety glasses when operating a reciprocating saw.
