Likewise, how long before I can paint over knotting solution?

Similarly, is knotting solution necessary? Before you go anywhere near a can of paint, you need to carefully apply the right number of coats of knotting solution. Knotting solution is usually applied using a brush or cloth, using at least 2-3 coats to completely cover the knot and prevent it staining the final paint finish.
Also to know is, does knotting solution go off?
Knotting solution can really only hold back extractive staining, from knots and resinous areas of timber bleeding through the paint coating film. It won't stop actual resin exudation, or bubbling of the paint film when the resin turns from a liquid into a gas. Do not overcoat with other coatings until fully dry.
How do you seal wood knots before painting?
Priming Bare Wood If you are deciding to paint bare wood, you should seal all knots (spot prime) with a shellac based primer. Shellac based primers are great for sealing wood knots and sap streaks. They do carry a pungent odour, but dry very quickly and will not let the knot bleed through the top (finish) coat.
