Before fixing your new skirting board prepare those boards which will meet at the corners of the room. Most corners are meant to be square, so it follows that fitting skirting boards around such a corner, the mitre cut would be 45 degrees, and to aid the accurate cutting of such frequent cuts, mitre blocks can be purchased pre-cut at this angle. Ideally though, mitre boxes are better for cutting skirting boards, as they give better control. octopus skirting & decorating
An uneven floor may leave ugly gaps below the skirting. To remedy this you can mark and cut the bottom of the skirting so it will follow the profile of the floor. You can push small wedges under the skirting board until it is level. Ensure your new skirting board is the same height as the one you are replacing, otherwise you will have a gap between the top of the skirting and the bottom of the plaster, which will need to be patched.
To fasten the skirting to the wall a grab adhesive is best especially if you intend to stain or varnish the boards. This will depend how straight the wall is though. If you are fastening to a stud petition wall you can simply nail the skirting to the stud work or if it is a brick wall you can knock wooden wedges into the gaps between the bricks and then nail into the wedges.
If you are fixing skirting to the wall of a long room or hallway you may need to make a joint before reaching a corner. Before the angle can be transferred to the skirting, the skirting board itself will need to be marked to show the position of the mitre cut, which is done by placing the board in position against the wall, and marking the base of the skirting where the external lines cross on the floor, with another mark at the top at the plaster arris.
With the wide range of tools available these days, fitting skirting is quite a simple task. You could very easily hire a sliding mitre saw from a tool hire shop for the day and fit most skirtings very precisely with ease. With a little practise, you will soon be fitting skirting like a master craftsman.
