You can apply oil or water based paint on top of zinsser bin according to the data sheet, although I have only ever used oil based undercoat and top coat over it.
If you're working on a larger project I recommend a microfiber roller. In addition to preventing bleed through, BIN Shellac sticks to any surface without sanding.

DRY & RECOAT TIMES

The drawback to using shellac-based primers is that they are not as versatile as latex or oil and they give off more fumes. They require that you use denatured alcohol to thin them and clean applicators.
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. Spot priming is recommended only under high-hiding topcoat finishes. For best results, prime entire surface before painting.
Water-based primers even out patched or repaired surfaces very well. They can also cover and seal in previous minor stains from smoke, lipstick, crayon, etc., but are not as effective at covering stains as oil- and shellac-based primers.
It's important to note that Zinsser Cover Stain is an oil-based primer, which means it has a strong odor and requires proper ventilation during application. Additionally, if you're planning to apply latex-based paint over Cover Stain, make sure to allow the primer to dry thoroughly before applying the paint.
Shellac is most often used in artwork as a sealing finish on wood or other porous substrates that will later be painted over. It can also be used as an isolating film between layers of paint, both oil and water-based. Dissolved in alkali and water, shellac can be used in watercolor painting as a fixative.
A: the primer is quite runny, so I found that a short-nap roller on smooth surfaces worked best.
Zinsser BIN Primer is a basecoat that can be overcoated with any paint finish including matt.
Natural bristle is the best choice for oil-based paints, varnishes, shellac, alkyd enamels, oil stains and oil-based polyurethanes. The highest quality bristles come from mainland China. Experienced, traditional painters will say there's nothing like the finish that a China bristle can provide for oil-based coatings.

Dry Time– In most cases B-I-N® will dry to the touch in 20 minutes and can be recoated in 45 minutes. The dry primer film develops full adhesion after it cures in 1 to 3 days. Lower temperatures, higher humidity and the addition of tint will prolong dry and cure time.
You only need to sand if there are brush strokes or other blemishes. Also you don't need to sand between coats. I only sand if I have brush strokes or drips (I'm finally getting to the experience level where this rarely happens).

Shellac/alcohol based primers like Bulls Eye work great for sealing stains and odors in many applications, however they do put out a lot of alcohol fumes. Spraying increases the amount of volatile gases in the air and should only be used in a very well ventilated area and with proper protective respirators.
