How to Make a Longboard Surfboard

by Jeffery Keilholtz

Making a model longboard surfboard is a creative way to express your passion for the ocean. Originating in Polynesia in the early 20th century, longboards first made headway in the United States off the coasts of Hawaii, according to Long Board Surfboard. California surfers eventually took notice of the longboard during the 1950s and 60s and the rest is history. Because of the extended surface area, longboards are ideal for training amateur surfers. Display your craft version of a longboard on a mantle or bedside table as a constant reminder of the stoked feeling one gets from riding waves.

Items you will need

  • Cardboard
  • Measuring tape
  • Pencil
  • Scissors
  • Straight-edge knife
  • 1/8-inch-thick high-density urethane foam
  • 1/16-inch-thick polyethylene plastic
  • 5 cups water
  • 1 cup flour
  • Pot
  • Medium-sized bowl
  • Newspaper strips
  • White paper towel strips
  • Acrylic paint
  • Paintbrushes
Step 1

Trace the outline of your longboard onto a flat piece of cardboard. Make the outline 10 inches by 3 inches in dimension. The shape of the board should resemble a long, narrow oval. Cut out the shape. Repeat on a second piece of cardboard.

Step 2

Repeat step 1 on one piece of foam and two polyethylene plastic sheets.

Step 3

Build the board. Layer the top side of the foam with permanent epoxy. Fit and press one of the cardboard pieces down onto the top side of the foam. Hold the press for 30 seconds to secure the bond. Bond one of the polyethylene sheets to the top of the cardboard in an identical manner.

Step 4

Flip the board over and repeat step 3 for the opposite side.

Step 5

Trace the outline of your long board fin onto a flat piece of cardboard. Make the fin 2 inches by 2 inches in dimension. The shape of the fin should resemble a dolphin fin. Cut out the shape. Repeat for two pieces of polyethylene.

Step 6

Glue one piece of the fin-shaped polyethylene to one side of the cardboard fin with permanent epoxy. Repeat with the second polyethylene piece for the opposite side of the cardboard find. Place the flat side of the fin at one end of the board, at center. Glue the fin into position. The board is now complete.

Step 7

Combine the water and flour into a pot to make a paper mache mix. Boil the mix for 3 minutes. Allow 5 minutes for the mix to cool. Pour the mix into a medium-sized bowl.

Step 8

Dip one strip of newspaper into the mix. Press the saturated piece of newspaper onto the body of the board. Repeat until the entire board and fin is covered in one layer of newspaper mache.

Step 9

Repeat step 8 with white paper towel strips. White paper towel provides an ideal surface for acrylic paint. Allow 4 hours for the craft to dry before painting.

Step 10

Paint the board and fin with acrylic paint. Contrast the colors between the board and fin. Make the fin, orange, for example, if your board is blue. Contrasting colors helps the board and fin stand out from one another. Allow 2 hours for the paint to dry before displaying or handling.
