What is the difference between Zinsser 123 and Cover Stain? While both stand as top-tier products, the 123 is known for its stain-blocking properties across all surfaces. On the other hand, Cover Stain, being oil-based, stands out with its high hiding formula, adept at concealing difficult stains and imperfections.
The Best Stain Blocking Primer
Our personal recommendation would be to use Zinsser Coverstain, which is a low odour oil-based primer & stain blocker. Zinsser Coverstain can be used both on interior & exterior walls and is especially effective on nicotine and water stains.
Zinsser BIN is shellac-based, whereas 123 is water-based. This makes Zinsser Bullseye 123 a lot quicker and easier to apply. It's also better suited for use on bare wood, or to prime plastic and composite before painting. BIN may be harder to apply, but it is by far the better stain block.
Zinsser BIN is a shellac-based paint, Bullseye 123 is water-based. They're both adhesion primers and stain blocks, but each one is better for different jobs. For example, Zinsser BIN is better for blocking water stains and gripping to varnished wood. Zinsser Bullseye 123 can be used outside and works better on plastic.
When priming MDF wood for painting, we recommend Zinsser BIN Primer. BIN primer is a shellac-based primer that creates great adhesion for your chosen topcoat. A fast drying primer, it can be applied directly without any sanding and is ready for a topcoat after just 45 minutes.
B-I-N® is the ultimate primer, sealer and stain killer. It offers unparalleled adhesion on any surface without sanding and has the hiding power to conceal the toughest of stains.
In the category for best primer for painting stained wood, our results found two top performers. They are Sherwin Williams Extreme Bond Primer, and Behr Bonding Primer.

You generally don't need to sand new wood that has been stained before painting, but it depends on the results you're after. If you want a super-smooth painted finish, scuff-sand, which is lightly sanding (scuffing), the surface by hand (not with a machine), to smooth out bumps using 150- or 220-grit sandpaper.
In most cases only one coat is necessary to prime most surfaces. If excessive absorption occurs over very porous substrates a second coat may be necessary.
A: the primer is quite runny, so I found that a short-nap roller on smooth surfaces worked best.
Zinsser Cover Stain provides durability and adhesion on smooth and glossy surfaces. It's especially good fro using on outside jobs. Zinsser BIN is the toughest with the highest adhesion although it does have the highest price tag.
