   Tim,

   It will take quite a few coats of paint. You might have better luck using white shellac first. It's available named as such and by various other names like "KILZ" implying its ability to kill a stain or even an odor in wood.

   Tim,

   I would start with using a good sealing primer. Since you don't have any bonding requirements avoid bonding or bondingsealing primers. Both bonders and sealers work better by themselves then when mixed so when you only need one or the other, it's best to stick to it.

   The best way to conceal knot holes is good old shellac.  Zinnser makes a pigmented white 3lb cut shellac. Or you can get flakes and make it wityh denatured alcohol. Sap wont bleed through shellac.  Nothing beats bug poop to cover pine knot holes easy.

   I'll agree Bill that shellac is the best for a low price. Either way, all that's needed here is a sealer. It doesn't seem like he is having any problems with bonding, so a bonder isn't necessary. It's kind of like polyshades. Stain is fine and urathane(sp?) is fine, put them together, polyshades, and they suck in my opinion.

   Get a spray can of KILZ white shellac and spray the knotholes. Then paint with what you want.  We had knotty pine pannelling that we painted.  The painter sprayed every knothole--the room looked like a Dalmatian.   That was 30 years ago--none have ever come through.

   And if the knots show divots after you've primed them, go to an auto paint store and get glazing compound. You can put it on with a putty knife and sand it shortly thereafter. It're pretty good for going over paint to fill voids. A product a lot of painters use is Crawford's spackling for the same thing. It fills lots of nicks and voids, dries well, shrinks almost none, and sands out like drywall mud. Really good stuff to have around the home.

   Interesting this is showing up now. I'm in the process of painting some areas on the front of my house including several where the knots bled through brown as described. The house next door is being painted by some professionals, unlike myself. Before starting, I asked them for advice on what to do about the knots. They said to slap on a coat of Bullseye (Zinser Shellac) as a sealer before painting. They said the builder had used the wrong sealer and that shellac would take care of the problem. (Of course, use the dewaxed shellac, which Zinser sells as a sealer.)

   I have no problem with picking up a can as I can use it for furniture projects if there is any left. Can't say if it is going to work as I am still applying paint,but the advice I was given corresponds with what is being said here. Hence, I'm feeling good about the choice.

   I don't think it makes any difference in this use.  Just more expensive I would guess.Gretchen
