Painting a pine windowsill

2013Lara

OK so it may be easy for many of you but what are the steps involved. I have a mix of sand paper, have white spirit, undercoat and the gloss. Do I need anything else? They're not in great nick and obviously have been left as plain pine since house was built 8 ish years ago. Doors are the same and we plan to paint them too. Any advice, I don't want the paint cracking and chipping in a years time!

You need to sand it back and use a special primer 1st, ask in a paint shop. Maybe some of the zinser range

Thanks a mill. So sand it, then white spirit then primer then undercoat then gloss?

That'd do it alright.

Yep, after you prime it, fill any holes and cracks with filler. Then sand,undercoat and gloss

Add a little white spirit to some undercoat and use that as a primer, save a few yoyos. Then, fill any imperfections, sand lightly, undercoat and gloss.

Thinning the undercoat us fine for undercoating but use a proper primer like zinser. Otherwise it will peel.
was there varnish on the window boards ?

Undercoat peeling? Thats new to me.

Op said they havnt been touched in 8 years, if they were varnished originally then they will peel as the undercoat won't penetrate the wood. The doors were probably prefinished in factory. http://www.zinsseruk.com/how-to-guide/how-to-paint-woodstained-or-varnished-surfaces/

+1 on the Zinnser primer recommendations. If previously varnished I would rub down with sandpaper to provide a key for subsequent coats. Clean down with white spirit on a rag and prime with Zinnser Bullseye (the shellac based one). Follow up with undercoat and gloss. I would caulk joints where board meets reveals and window with acrylic caulk for a professional looking finish.
