Painting/ Mildew Question

[Jean in Newcastle]

I have an unpainted/unstained wood windowsill that has had a problem with mildew.  I have cleaned the windowsill with a bleach/water mixture per instructions from the internet.  There are still some black stains remaining.  I'm thinking of just painting over it all with an enamel paint (because I already happen to have some) once it is completely dry.  Good idea?  Bad?  Reasons why?

Sand it first.

Try to clean it with borax dissolved in water - and let it dry naturally. In my case, it took away the mildew stain.

 

If that does not work, I think that you can coat it with a primer that has anti-mildew properties (e.g. Zinnser Mold killing primer) and then paint on top of it.

Sand it, then use kilz.

I am a BIG fan of Zinnser!

Agree with prairiewindmomma. Kilz it first, then paint over it.

Kilz will do it. That's its whole purpose. Contain the ick after you've done all you can and let you start afresh.
