Prime with Kilz lacquer type primer. It will seal the knot and oils so they don’t make a brown circle later on. My favorite latex paint comes from Ace hardware. I like the Clark & Kensington line.

BIN shellac primer is the only thing that works well for pine knots.

Either kilz or bin, but do not use the latex version. Get the original formula.

You talking about the grain of the knots? Lightly dish them out with an angle grinder and fill back to flush. ****, gone.

Think of it as bodywork. Paint the knots with KILZ oil primer. Then sand down to a smooth finish so the 1st primer applications serves as filler. Then prime the whole thing. Then paint.
And if that is too much work to get a finicky finish, better just buy another door. Or tell your OCD to ****************.

It has to be shellac based primer. Do 2 coats of primer.Either kilz or bin, but do not use the latex version. Get the original formula.

Kilz oil primer 100%. You will not have any issues

The problem isn't the grain texture. It's the resin. Knots will exude sap over the years that will add a brown stain to latex paint above it, since latex doesn't block the migration of, well lots of stuff (after five coats of latex paint over a red stain, and a few months later, it always seems to reappear, I've learned my lesson).You talking about the grain of the knots? Lightly dish them out with an angle grinder and fill back to flush. ****, gone.
If it were my door, I'd prime the wood with an oil based primer, but first use a shellac primer over the knot. Though some oil primers claim to be better at blocking stains, and I prefer oil primers on wood in general, shellac is what you need to stop sap.

I did the same and like yours the knots started bleeding through and that was also with an oil based finish paint over top.I sealed some pine with BIN shellac a few years ago, 2-3 coats.
Knots are still showing through now.
