It is worth it as the knots are not absorbent and you may have stripped off the original seal :thumbright:

If you're going to be repainting, why not use BIN as a primer? Shellac based, so will cover both bases.

Yes, it is fine for water based paint over. It is a horrible paint to use and the first coat is streaky but comes good on the second coat. It depends what you have to hand and how many knots to treat. A 1 litre can of BIN is £20 in Screwfix whereas knotting sealer is around £8 a can.

You can often get a small bottle of knotting for about 4 quid..but BIN will do the job, if there is a lot of sun on the door i'd be tempted to use knotting under the bin or at least BIN the first first.
