AC Lacquers as a primer / undercoat for paints.

[Joe90]

Hi
Are AC (two part) lacquers suitable as a basecoat for a painted finish? I usually work in pine.

At the moment I use Zinnser shellac base BIN primer, two straight coats on the pine and I have a lovely white surface, then two top coats of Farrow & Ball, Dulux or whatever, eggshell usually. The BIN primer works very well but it takes time to apply and is more expensive than AC Lacquers.

Also if I was using AC lacquers as a basecoat I could spray the insides of the cabinets at the same time! I would be most concerned about a yellow-ie colour bleeding through a nice cream finish!

Cheers so
Joe

Joe, I do not think you will be able to do this as the solvents are different there by there will be NO chemical bonding between the Different finishes.

BUT ! iirc 2 coats of AC laq. cut back thoroughly and dusted off will ALLOW a MECHANICAL BOND.

Risky, due to the fact 1 chip/scratch and someone " could " use their finger nail to remove the top coats :? DAMHIKT ! but I have seen it with Frenh polish on top of an unknown finish

Still, you could try it out on a scrap piece and leave for 8 hours between coats, cut back wipe off with with a tack rag and then re coat with your choice finish.Leave for a day or 7 and then try a scratch test.

Wish you luck with it, imho better to stick to 1 laquer / finish system throughout to avoid latter headaches.

some good info there alright... I may try spraying the BIN primer then, spraying is obviously quicker than hand painting but is more messy and the clean up would have to be good as the BIN sticks aggressively to everything!!! I'd even say it would stick to glass or tiles! BIN isn't very viscous, in fact it is very liquidey when stirred so I may get by with a minimum of thinning using a 1.8mm nozzle.

I am a big fan of DeVOL Kitchens in the UK, once I saw their products I wanted to do something similar... this is a quote from their website..

Two coats of primer and two coats of paint are sprayed on and two further coats of paint are carefully applied by hand with broad even strokes following the grain.

I was wondering what primer they spray on as Morrells Woodfinishes are unable to supply a primer to be spray applied for pine. DeVOL use tulipwood (poplar?) and alder which don't have knots whereas I use pine which requires a first rate primer like BIN. My prices are cheaper though, if I charged anywhere near what they do I would also use hardwoods for everything.

Cheers HS.

P.S Morrells are very helpful and I consider their advice to be very good and authorative.
