Is Johnstones Trade Flexi Satin suitable for old UPVC frames?
I have some rather dated UPVC window frames that could benefit from an update. A local decorator suggested applying Johnstones trade flexi satin ( no primer needed) i just wanted to check thoughts on this ?

Yes, Johnstone’s Trade Aqua Guard Flexi Satin can work on old uPVC frames, but you’ll need to prepare the surface properly to ensure good adhesion and long-lasting results.
Key Considerations:
Adhesion: uPVC is non-porous and can be tricky for standard paints to bond to. Johnstone’s Flexi Satin is designed for flexible surfaces, but it’s primarily for woodwork, so extra prep is crucial.
Durability: uPVC expands and contracts with temperature changes. A dedicated uPVC paint (like Zinsser AllCoat or Bedec MSP) may give better long-term results.
I personally wouldn’t agree with this. I use 2k polyurethane paint on top of a 2k primer, the upvc has to be thoroughly cleaned, sanded, primed and finished. Zinnser is also a paint which can be used, it must e built up in multiple coats, personally I don’t think it has the durability or longevity of the 2k paint
I would only use a zinnser all coat all bedec multi surface paints,which can be applied by brush
Johnstone's Trade flexi satin will work fine on UPVC windows but I would always recommend applying a primer first to aid adhesion. Furthermore, be sure to clean down the surfaces first to remove any dirt or grime, followed by giving it a light sand with a fine-medium grit sandpaper.
I'm not a big fan using a Johnstone product. For UPVC you need to prime first, otherwise the paint will not stick to the surface. Depending on budget I'm using a benjamin moore, jenolite upvc, but ronseal upvc does a pretty good job too.
Johnstones Flexi Satin does a brilliant job but no primer is a bit risky if the surface is not sanded to make a bit of key to help the paint adhesion .
Johnstones Trade Flexi Satin is a good option for UPVC window frames as it's flexible and durable. It's designed for exterior wood and metal, but it can also adhere to UPVC without the need for a primer, provided the surface is properly cleaned and lightly sanded for better adhesion. Many decorators use it with success on UPVC for a modern, refreshed look. Just make sure to follow the preparation instructions carefully for the best results.
