The T&G cladding to my workshop walls will need re treating this year. This will be the second time in its 8 year life. Is there any way I can stop the knots weeping yet have consistent colour?

Knotting or shellac painted on the knot
Knotting I've used in the past was white which would show as patches through the preservative.

Drill the bastard things out!
well shellac will prevent the preservative soaking in, but its not white.
use preservative first, then shellac or equivalent.
Shellac isn't generally white.
The knotting I know is brown - being shellac. That seems to work IME.
The the resin from the knots will lift the whole lot off. The shellac/knotting needs to be the first thing applied. As for knotting being white I don't think the tin I have is but you may get a different texture/appearance where the knotting is.
preservatives that soak in rather than form a layer will not affect the stopping activity of shellac.
Yup, I once re-french polished the top of a cabinet using a bottle of knotting ;-)
Wet shellac could well turn white because it has virtually no water resistance. Add the tiniest amount of alkali and it's completely water soluble
Shellac comes in a range of colours:
(Piss poor spelling.) Some is even called white - though quite how white, I'm not sure.
Usually "blond" rather than white IME... (i.e. near to colour free)
