Hi everyone, I’m planning to paint over all skirting board to white color. Just want to know if I really have to sand all skirting board. I have tried sanding some skirting. After cleaning, as you can see the photo, it seems like the sanding is very superficial. Do I have to sand deeper?
Also, can I use same paint for the wall and skirting board? Any differences?
Thank you so so much!
