external painting advice wanted

[Robbox]

The timber windows in my house were originally painted with one of the microporous materials.

It was a mid-brown, opaque material.

The material has been allowed to deteriorate by the previous owners and this year I have to do something.

The actual timber has been exposed on the sills, but has not rotted or anything.

What is the best way to get these windows sorted without to much hassle?

I'd like to use another microporous material, but I wonder if I can get away with a one coat product like from Sadolin?

Am I going to have to sand any exposed wood back to bare wood, or just enough to remove any old paint?

Thanks

Sand down to remove any loose and flaking paint, dust off and apply two coats of Sadolin woodshield. I used this recently and it is very good stuff.

Thanks for the tip, just checked the product info, it looks perfect. These windows will probably have to be replaced in a few years, so I see no reason to spend a lot of time and money on them.
