Painting over oil based wood trim
#11
So most of the interior wood trim (base boards door ways etc) has oil based paint on it.

Is there a paint that makes repainting easier now? Really dont want to use oil based again. Quick drying easy clean up would be great

Or am I dreaming?

You can apply latex paint over any base.  Of course, adhesion is always a concern, so prep. is important.  First, clean it really well, then sand it lightly to remove any gloss and nibs.  The sanding will reveal any dents and you can decide whether or not to fill them.  The best job will result from using a bonding primer before applying the paint of your choice.  

Seal-Grip bonding primer by PPG works really well over oil based paint, and is available at HD.  For topcoat, my personal choice is SW's ProClassic Acrylic.  Goes on great with a brush, flows out nicely, dries quickly, and is pretty durable.  Even easier to apply is SW's Emerald Urethane Trim Enamel, but it takes a lot longer to dry and cure.

Latex can cover oil base.

Wash it and then sand it or scuff it with red ScotchBrite. Pet peeve of mine.. lack of prep. Every layer of paint over dirt just keeps getting uglier.

Easiest and fastest way is to cover with shellac based primer, then paint.

No need to sand and you can tint the primer to the final coat color.

The last time I used shellac based primer I thought my house was going to explode. Wow! Even with windows open that is some strong smelling stuff.
Any free advice given is worth double price paid.

It's just alcohol.  Not to worry.

When refinishing after others, I’d say I’ve never seen old paint that didn’t need sanding before being repainted because the previous work looked like crap!

Just so we're all on the same page here:  latex over oil is fine.  Oil over latex is NOT good, right?  The latex needs to pass moisture that the oil-based paint will seal in as I understand it.

The sanding is to promote adhesion in this case as much as to smooth out any flaws.  Latex will peel off really easy if it doesn’t have anything to bond to……….like a smooth , non-porous molding.
