What Is Zinsser BIN Primer Sealer?

Zinsser BIN is a white-pigmented, shellac-based primer that seals surfaces to keep sap and tannin from bleeding into paint when painting wood. BIN is what I use the most for priming kitchen cabinets and tough stains on drywall. This product can also be used for minor spot priming outside (wood knots, sap stains, nail rust, etc.).

I'll share a few pros and cons of this product, based on my experience.

BIN vs. Oil-Based Primer


I use BIN shellac primer and Cover Stain (oil primer) a lot in different situations. When applying the material with an airless sprayer, I prefer BIN, especially for priming cabinets. The material is very thin and levels over wood better than any other product I have used.

The super-thin consistency fills in pores and small surface cracks in wood really nicely with a sprayer. Cover Stain is thicker and doesn't level nearly as well as shellac does. If the spray gun spits onto the surface while spraying, the imperfections won't level out, which means more sanding.


The fumes with either one are horrible. Unless you're spot priming, a respirator should be worn when coating doors or whole walls. But since pigmented shellac dries faster, the smell doesn't linger as long. The dry time is only 45 minutes.

Brushing and Rolling

I never brush and roll BIN because it's horribly messy. For that reason, I only use it with my sprayer, or the spray can. The material is the consistency of milk, spattering all over the place if a brush or roller is used. Oil primer is messy too, but it's the better option for brushwork.


Shellac-based primer dries harder, making it a little more difficult to sand than oil primer. Both sand into a white powder, but Cover Stain sands a little easier. Shellac reaches maximum hardness three days after application.


Shellac cleans up with denatured alcohol or ammonia. I find ammonia to work the best for cleaning, especially for a sprayer. Ammonia is cheaper too. The disadvantage is the horrible vapor. Oil primer cleans up with mineral spirits, which smells bad too.

BIN vs. Sherwin Williams White-Pigmented Shellac Primer

The white-pigmented shellac primer from Sherwin Williams is almost exactly the same as BIN, but in my experience, there are a few differences.

The first difference is the cost. The white shellac from Sherwin Williams is $60 per gallon at full retail price. However, you can get a discounted in-store price by signing up for their free Paint Perks benefits.

A gallon of BIN is $42 per gallon. For spot priming exterior trim, or drywall, it's cheaper and less messy to buy a spray can, but even the gallon price is the better deal unless you get contractor discounts at Sherwin Williams.

The shellac from Sherwin Williams dries slower and smells worse, in my experience. The consistency of the material is the same with both, but the coverage with the Sherwin Williams one isn't as good. It also doesn't sand as easily.

Is It Worth the Price?

I use Zinsser BIN primer on cabinets and recommend it for spraying them. The aerosol cans come in handy too when you need to do quick spot priming before painting. Brushing this stuff is extremely messy because the consistency is so thin. I only spray this product.

The primer lays out exceptionally well and won't sag easily because it dries fast. I can sand it and apply a second coat within one hour. It doesn't sand as easily as some of the oil-based primer I've used, but the durability and coverage is very good. I've never had a problem with bleed-through using this product. The downside is the strong smell before it dries, but the smell doesn't linger like oil-based primer.

Questions & Answers

  • How bad is the smell when painting a stairway?

    If you mean priming and painting stairway walls or the wood railings/spindles in the stairway, the smell of the primer would be strong in an enclosed area like that without using a fan to help circulate the air. Opening windows with a couple of box fans set up will remove the fumes really fast though. The smell of BIN doesn't linger as oil primer does. Use low VOC paint to reduce odor.

  • Do you think Zinsser BIN would cover mold spots on a bathroom wall, prior to painting?

    Yes, the primer will cover dark stains left behind from mold, but the actual mold itself should be removed before priming and painting.

  • We've just bought a house and the previous owner smoked inside...would B-I-N seal/eliminate the odor?

    Yes, the primer will seal over the smoke stains and help remove the odor, but you should clean the surface before priming.

  • I need to use the primer to prime cabinets that are stained. Do I need to sand the cabinets enough to completely remove the stain or do I even need to sand at all if using this primer? Also I would really prefer to use a brush and roller, does this mean I shouldn't use the BIN or SW?

    The cabinets should be cleaned and sanded to remove the glossy clear coat. This allows the primer to bond stronger to the surface. Use an electric sander with 150-grit sandpaper. You can brush and roll BIN, but it's messy to work with because it's as thin as water. It sprinkles everywhere. You have to be careful to cover everything around and beneath the cabinets, you're priming.

  • I have just primed some old Pickwick paneling in our home with BIN. The paneling had been lightly sanded then cleaned. I applied 2 coats of BIN with about 1 day in between coats. Then Iapplied 1 coat of Sherwin Williams Primer in 200 Eggshell. It has cured for a little over a day. The paint is easily scratched off with my finger nail. Is this normal? Does it need longer to cure before I apply the second coat?

    The primer should have been sanded too, but the problem here is the ProMar 200 paint. It's not a durable product for paneling. It dries too soft. Emerald urethane enamel in the semi-gloss finish would have been a much more durable product for your paneling. It dries hard. The ProMar paint might harden a little over the next couple weeks, but your best bet is probably going to be removing the paint and applying a durable product like the one I mentioned.

      I have applied BIN over CAT pee rotted pressure treated 2x4 were the base boards go. I took as much rot out as i could but the 2x4 stil looks soft and black . I dont think it can dry out anymore, it looks like soft rot. Well, i primed over it anyway to kill the odor, do you see any harm in what I did? Did I block in the decay? Or the chance of really drying out more?

      Remove the grease first. If the cleaning exposes bare wood spot prime those areas and paint the doors again. You can try touching them up, but it's hard to blend in touchups with glossy enamel, especially if the cabinets were sprayed. If the cleaning doesn't burn through the enamel down to the bare wood you can just repaint them without primer.

      Hey! I painted my kitchen cabinets this summer. I cleaned with TSP, sanded, and put on BIN. I sanded again, and then 2 coats of alkyd enamel paint. However, some cabinets have grease coming through!! Agh! Do I need to start completely over? Can I just do primer + paint again? Do I need to sand it? Please help!

      I am painting my oak cabinets. After 2 coats of Kilz primer and 2 top coats, the wood grain is still very visible. I bought BIN today in the hopes it will tone down the grain. My question is can I use BIN on top of all those coats? Do I need to sand the doors before applying BIN? Thank you!

      Yes, sand between coats.

      After I apply BIN, should I sand before I paint?
