I wish to replace 95mm skirting board with 145mm skirting board. Some
advice please -

1. Once I have taken off the old stuff , I will need to back-fill the
now exposed brick - do I have to plaster ? Alternatives ?

2. I notice from postings that some people have glued skirting - is
this really going to work with 145mm stuff ?

3. Along one wall, I could lay a 4m length - is this wise i.e.
warping, cupping etc ? Do I need to acclimatise the wood as one does
when laying T&G flooring, for example ?

4. And as to using a Mitre saw to get good joins...

Thanks - will start when the rains come !
