Polyurethane over laquer?
I've been trying my hand at veneer inlays. Deft spray laquer seems to give
a great looking finish, but I doubt if it would stand under wet drinks. Any ideas as to how polyurethane as a protective top coat would bond to a laquer finish |

How's 'bout scuffing the lacquer, apply dewaxed shellac, and then the (ugh) poly? dave |

The "(ugh) poly" tells me something. I'm open to ideas. What is the
objection to poly? What are viable alternatives. The surface will be used as a tray and from time to time will be exposed to a variety of liquids including alcohol. "David" wrote in message ...

I don't think that's true unless you pile it on. But for application, I prefer spraying water bornes. They can be recoated in under 40 minutes and don't stick to everything around the spray area. Brushing poly often results in bubbles and it dries too slowly for me. Thin the poly to reduce bubbles. Spraying it makes on heck of a mess due to the sticky residue of overspray. Dust can settle on a slow drying finish like poly. I can't recall seeing any appreciable dust nibs on my water borne finishes. But the poly is gonna be more water resistant than WB even with Crosslinker added so I can appreciate why you'd choose poly. I've got a poly'd desktop that is softer (after more than a year after the finish was applied) than WB/Crosslinker that has set for a couple of weeks, BUT the poly does better on the water torture test...

I've sprayed WB Varathane with sat results. Have you tried it?

Dave Nope, haven't tried any current Varathane products since I didn't like their god-awfully slow drying Varathanes back in the 70's. Not that a WB would be slow drying, but I tend to avoid certain brands like the plague, such as Minwhacks and others that I've had less than stellar results with. sometimes my biggest issue is not the final results, but the odor, slow drying, or other bugaboo.

My history with Flecto Varathane goes back to the 50s and working with
oil based shtuff was the norm. Several tries of the upstart WB products certainly didn't convince me they were even headed in the right direction. Update to today, all is well! Oil stuff is phasing out of the cabinet being replaced with WB stuff including WB lacquer. Get a small can of Varathane Diamond (believe that's the WB) gloss and TRY it, you might be pleasantly pleased!

Why not learn to apply polyurethane and skip the lacquer? Yes, it will
take longer to cure increasing the likelihood of dust nibs but the sandwich you are asking about is asking for trouble. How much water are you talking about? Lacquer has moderate water and water vapor resistance, poly has pretty good resistance. Good Luck. "Bubba" wrote in message . .. I've been trying my hand at veneer inlays.

I prefer the clear view that gloss provides without the flatting
ingredient and it can be toned down with abrasive pads to whatever sheen desired.

Dave Dave for flat surfaces I agree (unless you use Enduro products, which don't obscure the wood when you choose the flattened sheens), but for items with lots of difficult to sand nooks and crannies, trying to tame the gloss after the finish is applied can be a PITA.

Point taken, thanks.
