Zinnser Bullseye 123 questions.

[solo]

Have a tin of this stuff that I'm going to use over some existing oil based gloss. I have some bare wood skirting that I thought I may as well give a coat to.

Once applied to the gloss, should I then use a WB undercoat prior to applying the top coat, (thinking Armstead Quick Dry satin), or can the top coat be applied directly to the 123?

Likewise, for the bare timber, will a primer/undercoat or just an undercoat be required if at all?


TIA.

123 is a primer undercoat, great stuff, on bare timber you might need two to give a good white base coat

Thanks for that.
