Trim Painting Question...??

I know that there are quite a few threads on this subject but I have become more confused the more I read. Moving into a new house next week, the S/O wants to start painting inside ASAP, the house is all white. The house was built in '84 and has stained and varnished baseboards and window sills. The question is on prep, prime and paint. I have read to never mix oil based with water based but I have also read for this application to use an oil based primer with a water based topcoat, which is correct?? I am assuming the steps are sand, prime, paint. I will be using SW products and am a beginner but can paint a straight line. Thanks for your help!!!

Welcome to the boards.. and you've done some good reading.
Yes, you're right. Sand, prime and paint. A fine sanding to roughen up the varnish and stain, a good oil based primer and then top coat of choice for all you want to the sills. .
You may want to consider new thats alot of material to redo. You'd probably want to remove the baseboards to repaint, so it would be easier to get new baseboards, which generally come primed already, then you just have to paint them. Even if it may seem like a lot of base to replace, it would save you alotta time to replace with new and paint them, vs all the work to redo the old ones. That would be my route.
Good luck..and let us know how you make out.

After cleaning and sanding, the varnish/poly must be coated with a solvent based primer. Pigmented shellac is best but an oil base primer is fine. The folks at the paint store can help you decide which primer is best for you.

I would use a problock primer and 2 coats of proclassic waterborne enamel but latex enamel or oil base enamel can also give decent results. i almost always paint the baseboards in place but jatco is right if you do remove them you will probably be better off replacing them.

Its perfectly ok to topcoat oil-based primer with latex paints. Its done all the time. The cautions you;ve read about refer to putting latex paint over oil paints. Paints and primers are not the same thing. They have different formulations and different purposes.
