Is Shellac Really The Best Sealer????? 

adhesion with shellac is the number one reason I'd use it, along with the fact that it dries, it doesn't chemically cure. It's always live for more shellac, and it's even tolerant of a small amount of oil, etc. It'll stick to itself and the oil will come to the top, especially if it's rubbed on. I've done fresh wood or varnished wood with white water based primer only to have the tannins or something come through the top coat later. I don't know if the WB primer would've sealed those out if it had been allowed to cure for a week, but I didn't want to wait that long, either. With shellac, reactivity to water is low and I don't have the same problem. But it's definitely true that it's expensive and it goes on differently and often not in high color concentration. I think the reason you're counting solids and seeing less color density is because 20 or 25% of those solids are shellac resin.

With the shellac you will see the bleed through with just that as a primer coat. You will not see the bleed through once the top coat is applied.

I wonder what scratch test would show on each (stained area), testing stain blocking is good, but another major use of primer is improving bounding to substrate for top coat.

The elephant in the room that no one mentions, is that most vinyl sealers are a spray only product. Where as BIN brushes and rolls very easily. Also a lot less toxic. All situational. Great information here all the same. Thanks.

Oil primer works any time any situation.

I just tried Zinser synthetic primer v. the Zinser Shellac primer on two different furniture projects and there was no comparison. On two different pieces, the Shellac held like glue and the synthetic didn't. On my pieces, for the best bonding primer, Shellac is still hands-down the best.

2:18 - You should clarify that the 51% solids content is by weight. It is in fact 29% solids by volume. The shellac and pigment weights a lot more than the alcohol.

Great Info Eric.....Keep it Coming'.....

Good video! Do u got any for plaster walls or drywall for sealing in nicotine and heavy stains?

Please help. I applied shellac to sanded down cabinets. I applied 3 coats. I had them sit for 2 weeks before I was about to apply final coat of paint today. I sanded down between each coat of shellac. I looked at the cabinets today and there’s a ton of tannin bleed through. They look all pink. What should I do

Can I use emerald urethane over shellac primer?

Is vinyl sealer the same as poly vinyl sealer? I just used Chemcraft Poly Vinyl sealer over Old Oak Windows. Bin definitely covers better. It took 3 coats of the PV primer.

Is vinyl sealer anymore “hazardous” than bin?

What is the (brand) of the vinyl sealer? Is it the Rock from Inspired By You?

I am not so sure that just testing a primer alone gives the truest info. I think you need to test the entire system as certain topcoats in combination with certain sealers produce varying results.

I looked for axalta primer on their website but can’t find it. Is there a specific name for it?

What about cover stain under the 2 k poly from Milesi?

What if you put two coats of the bin on?

I like the BIN however the cleaning sucks, it crumbles and clogs my system, it’s a pain to clean!

Bin sealer as the name is a sealer. There's a great detail information about it from Zinsser : ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-bCb2_RUfNjQ.html
