When preparing wood for painting [I'm about to do my floorboards] I've
been told to use a knot sealer. What is this for?

Its a resin like shellac that is impervious to resin that will bleed out
of the knots. You just dab a thin coat on the actual knot. 5 minutes
that's it. Don't overdo it.

And if you've got a manky knot which is going to need filling and
sanding prior to painting, when's the best/appropriate time to apply
the knotting? Every time I have to do it I ask myself the question...
