Painting & Decorating Question

How to prep and paint timber doors and windows?

I have timber doors and windows on a 1940s semi.

On the front on the property the windows and doors have a dark oak stained finish.

On the rear they have a dark brown gloss painted finish. I can see some paint is flaking off and there appears to be a grey finish underneath - i'm assuming its some primer?

I want to re paint them all with dulux weathershield exterior satin paint (conker) which is a dark brown.

Some of the timbers have some rotting.

How should I prep the surface on the windows and doors to the front of the property where they currently have a stained finished. Does it require a primer. What grade sandpaper should i use. Do I apply silicone to the edges before or after paining? Please advise of the steps.

I've noticed in the past when I've painted windows and doors that they dont properly shur due to the extra layers of paint. How do you mitigate this?

Would a painter and decorator be skilled/knowledgable enough to fix the rot or should I be seeking another skilled tradesmans to treat the rotted wood first as these are expensive windows and I need the rot fixing properly prior to painting?

What type of tradesmans would be best suited to fix the rot - joiner?

Any tips and advice will be appreciated.

Hi
If your windows/doors dont shut properly you will have to strip the paint back to bare wood and start again,any bare wood should be primed,any previous painted or stained wood can be undercoated(oil is better)then top coated.
If u have rot in the windows you may need wood spliced in which a carpenter would be best.
Hope that helps

That would be an undercoat, the generic undercoat for dark colours is a grey.

You will find the more you sand it back to start with the additional coats wouldn't be such a problem.

If you're going to use a water based satin you're going to need to really give these windows a good sand down to provide a key for the undercoat to stick to.

I would suggest using Zinseer coverstain as a primer.

Does it require a primer. What grade sandpaper should i use.
Start with 80 grit and work higher up between coats

Do I apply silicone to the edges before or after paining?
After

If you have issues with rot then you need to look at a repair care system.

I hope this helps

A decorator how has knowledge with using the repair care systems, like myself would be best.
