How to repaint window frames?

[EllieBee]

 

The windows and skirting boards in my living rooms are burgundy. I want to paint them a natural white. 
Would I be better off sanding off the old paint so it doesn’t peak through underneath?

Hi @EllieBee,

Sanding off all the old paint would be quite a big task and unnecessary for most situations. While it would ensure the burgundy colour doesn't show through, you can achieve a great result with less effort. 

Instead of fully stripping the paint, I recommend giving the existing painted surfaces a light sand to create a good key for the new paint to adhere to. Then, apply a tinted primer in a grey tone, which will block the red hues from the burgundy paint much more effectively than a white primer would. The grey primer will help neutralise the dark undertones, allowing your natural white topcoat to go on smoothly and cover well. After the primer, apply two coats of your chosen white topcoat for a nice, clean finish.

I'd also suggest speaking with a paint expert in-store to confirm the best primer that can be tinted. That way, you can ensure you're getting the best result with minimal effort. This approach will save you from sanding off all the old paint and still provide a beautiful, smooth white finish.

Please let me know if you have any questions.

Thanks, Mitchell! 
May I ask, what should of sander should I use to get the job done?

Hi @EllieBee,

A random orbital sander is your best bet if you plan to sand it all back. They are lightweight, easy to control, and they are good for all kinds of general sanding. The only downside to them is they are round so they can't get into corners easily. 

For the corners, you could hand sand them with sandpaper or use a detail sander. A detail sander would be worthwhile if you have 10+ windows to do but I wouldn't call it a necessity if you only have 1 or 2 to do.

Let me know if you have any further questions.
