I'll be painting the skirting boards in my room as they are in bad condition. The paint is cracked and the surface uneven and blotchy. What I would like to know is how should I treat the skirting boards before painting them. From some googling I've got a rough idea of what I should be doing:
Strip the previous layers of paint using a paint stripper or heat gun, then apply a primer and then paint over this
Sand down the skirting board, apply a primer and then paint over this
The first seems quite a laborious task and i'm wondering if the returns are worth it.
Which of the above methods is better? Are there any other methods that are better?
The second seems more manageable however I'm wondering what kind of sand paper I should use? I'm aware that there are different grades, which grade of sanding paper is appropriate for sanding down paint on skirting boards so as to get the surface ready for a primer? Also is it even necessary to apply a primer to a wooden surface that has already been painted?
The paint I will be applying to the surface is of an eggshell finish.
What else can I do to ensure I end up with a good result?
