Painting over gloss finish

Woodville56

Having a slight problem at the minute with a painting job. We recently started to renovate our house which has gloss paint on doors, skirting, stairs etc. we wanted to put a Colortrend or F&B off white eggshell/satinwood low or mid gloss paint on the woodwork but our painter says that as these paints are water based, they won't work over gloss ! He proposes that we get a high gloss for the woodwork instead, but we don't really want a shiny high gloss finish. It seems he's not amenable to sanding down the gloss or preparing it in any way to use the satinwood finish we like ? Either way, from reading online about this situation, it appears that even putting gloss on gloss without sanding or priming is bad /shoddy practice ? Our painter thinks it will turn out fine however ??? Not sure where to go with this now ! Any advice ?

I'd sand it all down and give it a coat of undercoat first.

Has this painter started the job?

If not I'd be getting someone that will do the job right.

Gloss on Gloss needs a light sand usually - get shot of Mr. Bodge it now IMHO.

Give it a light sanding, apply undercoat and you can paint it whatever way you like.
Your painter sounds like a cowboy.

He's right on one part.

Putting waterbased directly over oil is futile. You'll need an adhesion primer to act as a barrier. We recommend a product called coverstain. The gloss will need sanded and cleaned prior to the coverstain. Then knock yourself out with F&B or Colourtrend etc.

If he's trying to convince you to use oil based, as I would, he must use an undercoat prior to any finish. Oil that has fully cured needs this. I'd say that's his plan but maybe it got lost in communication?

As far as what finish gloss, satin, eggshell etc that is your own preference.

I've been to the paintshop again and they suggest using a primer over the gloss ( they recommend a product called Zinsser BIN Primer Sealer) and they say you can use satinwood or whatever finish we want after the primer has done its job ? Just wondering now if I can revert to my eggshell for wood as planner after the primer coat ? Anyone use this primer product ? Is it adequate to deal with the gloss and give satinwood or eggshell ( both water based) a grip ? Did a bit of straight talking with the painter also and have him back on track as per advice here !

The bin primer is good quality. I don't know if it's ideal for your situation. Maybe someone else that used it like this can fill you in. Is it not possible to use an oil based satinwood or eggshell. This leaves a stronger hard wearing finish.

Most satinwood is oil based but I suppose they brands they want to use only have water based paint.

To answer your question yes it's adequate, but not the best no matter how much it costs. In certain situations BIN is wonderful. However it is prone to chipping.

Yes once you have your adhesion primer on, it's suitable for waterbased finishes including eggshell.

Coverstain, then f&b primer/undercoat then 2 topcoat if your lucky.

We had gloss on doors, skirts and architraves, light sanding and covered twice with colortrend satinwood French white....no issues
