Painting over gloss

Question

My daughter has used primer instead of undercoat on the skirting boards and door which was previously glossed and rubbed down. Do I still need to do an undercoat before glossing?

Michael · Answer

As long as its rubbed down. a primer is sufficient enough for you gloss over again

Looqman · Answer

Nah you should be ok just start glossing

Harry · Answer

You would get a better finish if it was undercoated

Daniel · Answer

You should be alright to go straight on with gloss 
If the primer’s gone on evenly and it’s got a decent, solid coverage, it’ll do the job of an undercoat as well. I’d just give it a light sand to key it, then go with 1–2 coats of gloss.
Only worth adding an undercoat now if it looks patchy or thin, otherwise you won’t gain much from it.

Yes most definitely so the top coat has a solid foundation

Ben · Answer

Should be more then fine to go over in with the gloss

Terry · Answer

No the primer will act as an undercoat just make sure it’s had a good run down

Hannah · Answer

Because you already had gloss I would have just painted over the gloss but its important to sand it down first

Richard · Answer

You should be fine with just a light sand for a key and then just gloss

Ryan · Answer

As long as the primer was painted evenly and doesn’t have any light or dark spots it’s absolutely fine to just gloss over the top
