I am hopefully going to fit skirting boards this weekend, being a bank holiday. Question is how do I do it? How do I get the 45 degree angles? Do I have to buy a specific mitre board? If there are gaps in the angles do I just use some sort of filler to fill them? What is the best method of fixing them to the wall? Can I use the same nails as fixing floor boards (not sure of the correct name for them but that was how they were fixed when I took them off)? Thanks
