Using Dulux Trade High Gloss

Hi Pete, I would personally recommend just a light sand down would be enough for the gloss the stick to, and to give you a perfect finish just sand down any lumps and bumps from the previous eggshell coat. That should be then fine to paint on top of no problem. Undercoat is only really needed on bare wood as new wood it will suck in all the shine/ oils from the paint and give you a dull finish, the eggshell will be your undercoat as such so should go on perfectly.

hi, and yes you should use an undercoat, but for what it is just a tiny job, wash with soap and sand down apply the gloss, job done.

Definitely will need undercoat! Gloss paint need good preparing to archive best finish.

Hi ..in my 20yrs + of being a decorator i dont leave things to chance and hope for the best..in this situation i personaly would definately sand the area down followed by a good quality undercoat followed by the gloss..

Dulux trade gloss is self-undercoating so there is not need to apply undercoat. You have to sand and then apply 2 coats of gloss
