Painting over Estapol Antique (1970's)

[littlebits]

I have four carved chairs which were painted with estapol antique, a base coat of one colour then a wash over the top. I don't want to strip the chairs back but I would like to paint them white and recover the seats. It has always been my understanding that one can't paint over this product but I am hoping there might be a product on the market now that would allow me to seal it and then paint over the top of it.
Look forward to any assistance.

hi,
you could try using Zinnser B.I.N its a shellac based sealer undercoat and works well over estapols, I have used for arctitrave and louver doors. As a belts and braces approach, something like Penetrol or ESP both wipe on surface preps work well, then you can coat with an undercoat or zinner etc. As a top coat I haven't had the greatest sucess with water based acrylics, but the newish dulux waterbased enamels do work well, or stick with a oil based enamel over the pre mentioned under coats. hope this helps.

If it is Estipol, it will be polyeurathane.

If you want it to be durable, you need to sand, not overly much but at least a fine grit 180 or 240, or scrub with steel wool or scotchbrite and be thorough...a mechanical key is required.

There is no special issue with estipol, it is more or less the same as other oil bassed gloss finishes as far as over coating is concerned.....any turps bassed or water bassed product should go over them.....the only real problem if trying to overcoat with thinners bassed products and two packs

Yes you can try penetrol or ESP or whatever..........but how lucky are you feeling.

As far as the zinzer primer...its a great product But I do not believe it will give you any advantage here.

The main advantage of the BIN primer is very good hold out, not particularly good adhesion to unprepared surfaces.

As far as the acrilics....standard interiour acrilics simply are not hard wearing enough for furniture.
The modified acrillic, enamel substitutes that most of the paint companies are offering are not much better.

In my experience by far the best water bassed enamel substitue is Reseene Lustacril/enamacril (enamacril is the gloss, lustacril is the satin), that are, from the ground up formulation and use their own tinting system.

One other option that most people never consider is turps bassed paving paint......its an opaque polyeurathane very similar to estipol, its hard wearing and dries fast, only problem is colour choice is not fantastic.
Berger jet dry or wattyl permopave......the permopave is slower drying..and the two brands do not mix.
