Painting skirting board and stairs spindles

[xyz321]

Hi, happy Easter
I am about to start painting skirting boards and stair spindles which are round . Saw a thread here with some questions but I have some more and didn't want to hijack that thread.

1. Any tips for what brush to use and how to avoid any brush marks. I want to use satinwood paint to match with doors which were painted a year or so ago (done by a professional at the time and not me! )

2. What the best size of brush, especially for doing round stair spindles and edges of skirting board.

3. I have old gloss paint on skirting board. After light sanding, can I use zinsser bin as undercoat?

1" brush would be about right for stair spindles, unless you really want to use the Zinsser up use plain undercoat rather than expensive Zinsser.

Thank you. Reason for zinsser was that I don't know what oil based gloss was used in first place. I was hoping that I can use water based satinwood. So I saw on Internet that zinsser is needed for this transition from oil to water without having to 100% sand the gloss.

If that's incorrect, do I need special undercoat or can I just use two coats of final paint with one serving as undercoat and the other as top coat.

Many thanks.

Hi,

I've just renovated my mahogany staircase with zin bin underneath for two coats and two top coats of Solvent Dulux trade satinwood.

I used these rollers to avoid brush marks and the finish was quite decent.

Don't see why you should need the Zinsser I have just glossed virtually the whole house with water based gloss over what was originally oil based gloss. Just undercoated with water based and glossed over, just keyed up the gloss first. You could always just go straight to top coat, but you will always get a better finish if you undercoat first with a dedicated undercoat and lightly sand again before glossing.

I would use the BIN. Previous owner of my house used water based satin on top of gloss, and although it 'stayed on' it was just a skin that could be peeled off with a fingernail.
