how to prep stained trim (no clear finish)before painting with latex semi-gloss?

Remodeling a BR in a farm house


trim work is stained - does not appear to have any clear finsih over it


Want to paint it a light semi-gloss latex color but past experience shows it to "bleed" through


How can I prep the trim for painting rather than replacing it?

Hi ishota64,


Painting your stained trim should be no problem.


Just make sure it is clean and remove any gloss or sheen by sanding it or using a deglosser.


If you're concerned about bleed through, you can use a primer such as Kilz Premium primer and stain killer.


Or for a one step job, use an all-in-one paint Such as Behr Premium Plus Ultra. This is an excellent paint and primer in one that covers very well.

 Reddish staining or bleed through is most probably from water soluble tannins  in the wood. All wood from evergreen trees have some degree of it. Other woods, such as mahogany, are also loaded with tannins. If someone stained the wood in the past, they might have used a dye stain, which could also cause bleed through.


An oil based , quick dry primer such as Zinsser CoverStain or the Original Kilz, will kill the stain dead and be ready to paint, with either oil or water based paints, in about an hour.  Acrylic, water based primers or self-priming paints require waiting almost a day to get maximum stain killing.


Further, oil based primers raise the grain of the wood less. They sand easier, leaving a very smooth, well sealed surface to take the paint better.

It's a good bet, ishota68, that if you follow Ordjen's recommendation, you'll get the results you expect!


Oil-based primer seals all surfaces without sanding (lightly sand only if you want the original surface to be more smooth).


Followed by either water-based or oil-based paint; semi-gloss or gloss will be most protective.



Oil primer will seal the original coating ... regardless whether it is dye or stain.


That Ordjen knows his paints and primers!!!
