Continue to step-by-step instructions

Step by Step Instructions

1 Locate the stud positions
2 Cut through the rotten board at the stud
3 Measure and cut the new weatherboards
  • Step 1. Locate the stud positions

    In this video we are replacing two rotten weatherboards. First, remove window frames or drain pipes so you have access to the damaged section of the weatherboard. Use the stud finder to locate the nearest stud. Mark the centre of the stud. Draw a line down the weatherboard at the stud centre to show where to cut.  Make the next stud along on the lower weatherboard. This means your joins will be staggered. 

  • Step 2. Cut through the rotten board at the stud

    Join two weatherboards and measure the depth of the thinnest part plus the thickest part of the board. Set the circular saw depth to this.  In this example it is 25mm. Cut along the line on the rotten weatherboard and slightly into the board above. Fill this cut later. Use the hammer, chisel and pinch bar to remove the damaged board. 
  • Step 3. Measure and cut the new weatherboards

    Measure the width and cut the new weatherboards to size. Insert the bottom board and pre drill holes at the studs. Nail the new weatherboard to the stud. Insert the top board in place and pre drill. Then finally nail into place.
