Knots are bleeding through paint. Previous to painting I sanded, 2 coats of good shellac on the knots, primed the wood then 2 coats of acrylic latex. Where did I go wrong? Is there a fix?
Thanks

Not enough primer.
Stain blocking primer.
In the UK we use 'Knotting primer' which seals the knots and stops the resin coming out. Surely you can get something similar in the US.
The shellac should have done that. My guess is that it was put on too thin, and not allowed to dry between coats.
The orange shellac should have sealed the knots. Hopefully, you used an oil under coater then the latex finish.
The solution now is to use "original" kilz.......not the water based kilz. Then finish again
