How to Fit Pine Skirting Boards

As well as covering the unsightly join between wall and floor to give a pleasing finished look, skirting boards also help to protect the wall from any damage that could be caused by furniture. Here at JAS Timber, we stock a wide variety of skirting boards made from pine, which are renowned as being the easiest to fit.

In this edition of our blog, we'll share with you an in-depth guide on how to fit pine skirting boards, along with some handy tips and tricks.

  • Skirting boards should be fitted flush to the floor so if the room will be carpeted, then the boards need fitting first. If the floor will be wooden, then the skirting boards should be fitted after the floor is laid. 
  • For external corners, which face outwards, joining the boards requires a mitre joint, with the board ends cut at angles of 45 degrees. Internal corners, which face inwards, require a scribe joint; this involves one of the boards being cut square and the other board being cut (scribed) so it matches the profile of the preceding board.
  • When fitting new skirting, you should commence at the door's left side, working around the room from there in an anti-clockwise direction. This is to ensure that the square cut of the internal corner is fitted before the scribed piece. 
  • To create a mitre joint, first measure the distance to the next corner before marking it on the reverse edge of the board. Also mark the direction in which you intend to create the mitre cut. With the front side facing you, secure the board into a mitre box and make the cut using a fine-tooth or tenon saw. Then do the same with the next adjacent board, cutting the 45 degree angle in the opposite direction. Sand the ends smooth and check that the two sections join perfectly. 
  • To make a scribed joint, begin by square-cutting the board that will become the right-hand section of the joint. The board that will form the left-hand section of the joint should then be mitre-cut as described above, ensuring that the angle goes into the corner. Use a pencil to mark the board's front edge down the profile from the start of the mitre-cut. Secure the board then use a coping saw to remove the waste section of the 45 degree cut. Check that the boards fit perfectly together. 
  • Use a cable/pipe detector to locate any concealed electric cables and/or pipes.
  • Following the manufacturer's instructions, apply grab adhesive to the reverse side of the board you are fitting. Press the skirting board firmly against the wall. If the wall is completely flat then other fixings will not be necessary. Walls that are not perfectly flat may require the use of other fixings such as screws or nails. Adhesive should also be applied to the faces of any mitre cuts. 
  • When fitting skirting to masonry walls, you will need to drill through the skirting into the wall using a drill with a 6mm masonry bit. Holes should be drilled 5cm from the wall end, positioned 2.5cm from the bottom and top of the skirting. Repeat the pattern at intervals of 50cm along the board's length. Holes should be countersunk so that the screws will be concealed. A 6mm wall plug should be inserted before 8-gauge screws are introduced and tightened.
  • Always fit the square cut section when securing internal corner joints. The scribed section is then aligned and secured without the need for adhesive. 
  • When all boards are fitted, use a caulking gun to apply flexible caulk to the top of the skirting, sealing it and filling any gaps between walls and boards. 
  • After filling and sanding countersunk screws (if used), the skirting is now ready to be painted or varnished as desired.
