What causes paint to bleed through?

In more complicated terms, bleedthrough is caused by tannins in the wood. If the tannins aren't sealed in, they seep through paint, or worse, they don't show up until you have topcoated your paint with some waterbased poly. OR they can even take their time and show up weeks after you have painted the wood.

Can you paint over bleed through?

My favorite remedy for bleed through/stains is shellac or shellac based primer. Other stain blockers that also work are oil based primer/paints, spray shellac, polyurethane or even wax. By applying any of these products, the stain or bleed through will be sealed and won't penetrate through your next coat of paint.

Why does the old paint showing through new paint?

The problem could be with the paint you are using. It could be defective, old, or a low quality paint that doesn't cover well.

Adding a Second Coat

After your first coat of paint is dry, it's safe to recoat typically after four to six hours. A good rule of thumb is to wait at least three hours to recoat your paint or primer if it's water-based. Waiting 24 hours is best for oil-based paint and primer.

Roller marks, which painters sometimes call "holidays," are a routine hazard when painting with a roller, and there are many ways to avoid them. When you notice holidays after the paint has dried, you can usually make them disappear by applying another coat after sanding lightly—if necessary—to remove drips and humps.
