Paint For Bathroom Door

[AKMild]

I want to repaint a white bathroom door on which there is existing white gloss that has yellowed. Does anyone have any advice as to the best make/type of paint I should use?

Whie gloss yellows faster these days than it used to because manufacturers were forced to remove a potentially-carcinogenic component of their old formulations. However 'trade' paints seem to have a reputation for staying white longer than 'DIY' products, with Leyland being a frequently recommended brand on several forums:

Most contractors say Johnson’s paints are the best.

Bear in mind that the Gloss that has yellowed is Oil-based, and a quick drying Gloss will not go straight over the top, without the surface being sanded first. Once that has been done, use some white spirit on a clean cloth, and rub the surface down, going with the grain, and then allow the surface to dry completely, before applying your fresh coat.

An oil based paint will yellow faster than a water based one but on the other hand a oil based one will give the much better finish. Before painting sand down well and then wash with sugar soap and rinse off. Then give one or two coats of undercoat depending on how it covers. After this give a light sand to get rid of any little bits that may be there even though you may not see them but will after applying the final coat of gloss. Using a tack cloth before you apply top coat can help with finish too.

Just to add.....
Oil based paints are being phased out.
