Hi First time posting.

Over a year ago I paint new doors with white water based satin. Doors were new and apparently we're already primed. Overtime the paint is peeling off in the areas where hands are making constant contact with the doors. Seems to be only happening with bathroom and living room door.

Assume I have gone wrong somewhere with the prep? Should I have sanded the prime door to create a key? Or used a primer before the satin? How best to fix now as its only patches?

Any advice is much appreciated

probably contamination from handling before painting, probably just needed a degrease with white spirit before painting.

Thanks for reply

So you think just because of handling while being fixed on. So I should remove the paint, maybe sand a little and then degrease?

You think that should do it.

Much appreciated

About 8 years ago I picked up some discounted primed doors from B&Q and gave them a light wipe over with dilute sugar soap, then 2 roller coats of Dulux Diamond egg shell Trade, though not a super finish due cheap 4" roller, they look same today as then.
For doors I do believe a good quality washable and hard wearing paint is a must.
Only one way out of peeling is a good sanding AFAIK, but not a decy and also not sure about white spirit before water based, my go to de-greaser is sugar soap or methylated spirits.
For sanding I use aluminium oxide but sometimes wet and dry on metals.

Ah thanks the input. Yeah I trying to stay away from the yellow gloss after a certain period.

Think I might go with sanding and then degrease before painting

WB satin is not that resilient for high traffic areas as its softer surface is easily marked and amino acids of finger and hand touches can cause stains. I tend to use Johnstones Aqua gloss which is a hybrid paint that is like a half gloss half satin. Once it has gone hard it is a tough surface which is ideal for doors and trims and you may want to have a think about this as a replacement finish. The Aqua undercoat is very good and after a light sand for a key and a wash down with meths for reassurance, it should give you a bright and resilient finish.

The Johnstone's Trade Aqua Guard in Satin gets good write ups too.
