Why is my paint peeling off

muffinek

Hello
I live in Victorian semi and paint on the bay window outside is peeling off really bad. Any suggestions why and how to fix? Sorry if it is really simple question but I dont know much about DIY.

Paint is doomed once water gets into the material.  I'd remove it all, ensure everything is dry and repaint.  I personally use oil-based paint for the outside.

As previous poster, either water ingress behind the paint, the paint is very old and needs doing again or wrong paint been used initially, so its starts peeling off. i.e internal wall paint used on external masonry.

Which direction do you face? Sun also flakes paint. 
Its a simple job but you will need some basic DIY tools.
1. Use a wire brush to gently rub all the really loose and flaking paint off, then sand the sill and mouldings. No need to get all the old paint off. Just rub it down  till smooth, ready to be painted. 
2.  If you have any cracks in the stonework, fill these with exterior Polyfilla. Leave to dry. Sand smooth.
3. Get yourself a tin of decent quality white exterior OIL-BASED gloss paint. Non-drip is easiest if you are a novice. You will also need a set of paintbrushes ( don't buy the really cheap ones unless you want to pick loose bristles out of your painting every few seconds). Put white spirit on your list too. This clears gloss paint from, window panes, hands, hair, small children etc.
4. Start at the top of the job and paint,working your way downwards to avoid dripping on what you have already painted. Wear some latex gloves to save yourself lots lots of hand-cleaning.
5. Keep the cat off the window  sill till the paint is dry!
6. Admire your handiwork!

A Victorian property, with what looks like stone detailing - An oil based paint is the last thing I would be recommending. It needs to be "breathable" (which the likes of Sandtex isn't) and compatible with stone & brick. It needs stripping off, either with a wire brush and a lot of elbow grease, or blasting with a gentle abrasive medium. Once cleaned of old paint, use either a silicate paint or a traditional lime wash.

Old buildings need to be treated with respect and appropriate materials used in repairs & decoration. Most modern materials are just not suitable.

Thanks a lot for all your input so far. Much appreciated. 

Can I pls ask for some recommendations of paints and paint removers that would be suitable for Victorian property?
