Gloss Painting - Stained Timber Archs/Skirting Boards

Hi, I am very new to this forum. Seeking some good advice from painters or those with knowledge.

I am looking at painting all stained timber architraves, skirting boards, door jambs and all the internal window Colonial bars with a gloss paint. My questions are;

• Should I lightly sand back first for good paint bonding?
• Instead of sanding could I just apply a good primer undercoat?
• Do I really need a primer undercoat?
• Do good quality gloss paints require a primer undercoat?

I am wanting to do a good job at this and any sound advice would be appreciated.

The other year there I painted all the outside Colonial windows at home did a pretty good job at it. I took my time, had the right good quality brushes and it turned out great.


Cheers
Michael

I have used "Zinsser Bin Primer Sealer" with some success. It is metho based and stinks a bit. I do not try to clean the brush at the end of the job. It is fairly runny (watery) but seems to do a good job. It is not often used and can sit on the shop shelf for a while, ask them politely to put it on the shaker machine.
You can Google for further info.

good idea to use u/c sealer then your top coats good to give a light sand use oikos non toxic special primer then oikos uni enamel :2tsup:

if you are dealing with the 70s funky dark timber stains - that'll come straight through anything acrylic in my (hard earned) experience, Zintsser is the stuff to use ... but get the turps-based one, not the acrylic.

A bit more messy, but worthwhile.

A light scuff is plenty, don't need more under that stuff
