"Not a painter, but i would give a light sanding over the surface to give your fresh paint something to key into."
it's just there is so much to be sanded it's a nightmare. Electric sander would be ideal

There are many things that you can use, but to be honest nothing is beer than some sandpaper and some white sprites to wipe it down.
Get a cheap electric sander for under 30 euro and a medium grit paper and you will fly through it.

This is very good advise but stick with beer only to drink.  |

Depends on the finish you want. If it doesn't have to be great then use ESP wipe on primer. Printable after 90 mins. Can be painted over with a couple of coats of finish colour. If you want it done properly you need to wash with white spirit,allow to dry then lightly sand. Apply one coat of Bins primer (shellac based) and 2 coats of finish. Bins can be painted over after half an hour. |

Paint for a living, you should always key up the surface to give your new paint something to stick too, I would sand with a fine sandpaper if your going to do it with a sander use a soft interface pad   |

a lot of bad information on this post, good prep is the only way to go, fail to prepare, prepare to fail, wash with white spirits , esp is good to etch the surface, or bin is the best adhesion primer and will also stop knots from bleeding through, but if you are going from varnish to a white or cream finish it's the job for a pro who has a good standard, |

"Hammerite paint, most other stuff a complete waste of time..
Hammerite paint is for metal not wood
Also excellent for sealing over varnish"
If u look at hammerites website they do not recommend using product on wood unless u prime first its ok on plastics and fiberglass |

As some one said earlier B.I.N 123 primer is best as you don,t need to sand down first it will stick to anything or use Allcoat paint which can be applyed again whitout sanding
as a PAINTER myself these two paint products works very well for me

Have to agree here, sanding is a must and wipe with white spirits to gather the excess dust |

Bin primer is ok, but I would recommend a light sanding and just using normal oil based undercoat. No matter what you use it is going to take 4 to 5 coats to get it solid, as the paint just sits on the varnish and doesn't soak in like it would on raw wood. The thing about using bin primer is, you will still need to apply undercoat over it, because it is next to impossible recoat 2 or 3 times, as it reacts and becomes soft. Colortrend prime 2 epoxy paint is also an option, its water based and less fumes.
Personally I would stay away from bin primer, only time I would use it would be to maybe cover up stains. Oil undercoat is your best option, just takes a little longer to dry, but it's the old school way of doing it and the best way.

Light sanding and a coat of zinseer primer. Then you are free to put water based or oil based paints on. Do not put a water based paint over was is most likely a polyurethane varnish. Zinseer comes in litre tins. Well worth it. Will keep for years too |

"For anyone into painting, is there a paint you can get to go straight over varnish without having to use Sandpaper first? It's a fucking nuisance "
There used to be this stuff call liquid sandpaper. You just wiped it on the surface which was to be painted with a cloth and left it to dry for about 10 mins. It was acted as a primer. Ready to paint. I used it for my kitchen cupboards. Did a great job. |

Colortrend prime 2 epoxy you can paint over oil based varnish and that's water based.
But whats the point in buying zinseer and then having to buy oil undercoat when you can just use undercoat and cut the cost. Have been using oil undercoat long before bin was on the market here and lasts just as long. |

i find waterbased paints sit perfectly on bin. Plus it drys much quicker than u/c but each to their own. |

Not disagreeing with you, but you can also use water based paints over oil undercoat, which is a lot cheaper than bin primer. Oil paint does take longer to dry, but is a hell of a lot more durable than water based paints. If you are doing a house full doors, frames and skirtings, oil all the way, is by far the best option. |
