How to prep and paint timber doors and windows?

[Adam78]

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 and window pane and beading before or after painting?
• What type of silicone should i use?
• How do i fix the rotting - filler?

Please advise of the steps.

How should I prep the surface on the windows and doors to the rear where it currently has a gloss finish.

• Will this require a primer?

I've noticed in the past when I've painted windows and doors that they don't properly shut due to the extra layers of paint. How do you mitigate this?

Any tips and advice will be appreciated.

Aluminium wood primer should cover the stained wood without too much drama, though you need to sand down all over first.

All rotten wood needs hacking out, treat the remains of the wood with a wood hardener. Then fill with a two part wood filler. Sand as required.

Any gaps can be filled with a exterior grade of caulk such as Painter's Mate which is paintable.
One or two dark grey oil-based undercoats after that.

A light sanding between coats is good to de-nib, ie remove any crud that's found it's way onto the surface.

Then put the gloss top coat on.

***

Surfaces previously painted with actual paint need sanding down, any bare wood should be primed, and any holes or gaps filled or caulked.

Then an undercoat, then the top coat.

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?

A lot depends on how rotten the wood is.

A decent painter can make minor repairs, though if the rot is extensive a joiner may be able to make a longer lasting repair.
