Stripped door frames back to bare wood, how do I prepare it?

[Sharpey]

Hello all.

I have recently stripped varnish and gloss off of my door frames and it is back to bare wood. I have sanded it down with a fine sandpaper.

What do I do now? I have a Crown Satin topcoat, and a Crown undercoat. Do I still need to prime the wood?
If so, would an MDF primer be OK for this task as I still have some left over?
If not, does it matter if the primer I might need is a different brand? Would any regular wood primer do?

Thanks for any help.

I too would like to know this one, usually I undercoat all surfaces that are being glossed with white matt emulsion, this saves you having to put a key on it for a new coat of glass and also makes the gloss sit on a strong white colour

Probably not what the pros do but it works for me

Firstly you will need to apply a knotting solution, the application of a primer is both designed and formulated to raise the grain of the timber and provide the ideal base for future coats.

This is of the utmost importance on exteriors, yet indoors a thinned undercoat will suffice. The diference between a waterbased primer undercoat and a specific oil based primer is the former can be used as both a primer and undercoat, and the latter only as a primer. It therefore is of the utmost importance that a specific primer should never be used as an undercoat.

OK, thanks for the replies so far.

So could I just get an own brand B&Q waterbased primer and use that? Something like this perhaps?

B&Q Quick Dry All Purpose Primer And Undercoat White


Then

undercoat >> topcoat?

Also, this is a silly question, but will the satin topcoat properly adhere if the bare wood has been painted already with primers and undercoats? It won't scrape off or anything if the knotting solution/primer is oil based?
