Undercoat and Primer

[rossk26]

So I bought a tin of undercoat and primer to paint some doors and some windowsils that I've rubbed back to the wood.

I got this... http://www.diy.com/rooms/fortress-trade-trade-professional-white-primer-undercoat-5l/136902_BQ.prd but I've realised it's solvent based, and I understand that you then can't paint on top of it with water based paint?

I've already got the Dulux Satinwood to go on top. Do I need to change the primer for a water based one? If so, any recommendations?

Since you're going over with satinwood (which is self undercoating) and it's just a primer coat you would probably be alright. But there is no way of telling how it will react, it's not likely to react but you could have a disaster on your hands.

Personally I don't like to go oil to acrylic without bridging primer, I use zinsser 123+ for that to ensure no nasty reactions.

If you're on a budget and priming bare wood you should use knotting solution then you could use johnstones joncryl.

In general I tend to find Jonno's trade paints to be better quality than dulux - dulux seem not to give a damn about the quality of their paints these days.
