How to Paint Knotty Pine

By:

Knotty pine wood paneling.

Is there a product that will cover up the knot holes in knotty pine should I decide to paint the wood a light color? -Judy

Hi Judy,

Knots, like those found in knotty pine, can pose a problem when painting, since the resin in them has a tendency to bleed back through the finished surface. To prevent this:

  • Spot prime any knots first with an oil based or pigmented shellac primer that is designed to prevent bleeding.
  • If there are a lot of knots, prime the entire surface to give it a more even texture.
  • If the boards have been varnished, lightly sand them and wipe off any dust before priming so the primer will adhere well.

More information on primers is available on our website at A Homeowner’s Guide to Paint Primer.

Good luck with your project,

Danny

    I have had good luck painting 50+ year-old knotty pine by priming with two coats of Kilz Premium water-based primer and two coats of Benjamin Moore paint. A small bedroom that was once a dark cave now has a very cottagey look.

    Hi Alison,
    To fill knot holes in flooring, I would use a mixture of epoxy glue and a dark sawdust such as walnut. To darken the patch even more, mix in a drop or two of universal colorant.

    I have a knotty pine bathroom. I would like to paint it.
    Should I use a oil base primer or a water base primer. I don’t want it to mildew. I am using a semi-gloss exterior paint after priming. Is that ok?

    Cheryl,
    Oil and shellac based stain blocking primers do a better job of keeping knots from bleeding through than latex primers. It’s not advisable to use exterior paints inside, as they may contain strong chemicals that are not suitable for an indoor environment.

    I have knotted pine in my den. I want it gone like last week. It is dark and the room has dark carpet. It would love to have wood floors, but I can’t have wood on the walls and wood and the floor also. Please tell me step by step how to paint the knotted pine and hopefully cover it with a nice light colored paint. Much love, Evelyn

    after I scrape and sand, can I use water based primer on exterior heart of pine before I paint?

    Hi Celino,
    You could experiment with an exterior, water based, stain blocking primer on a small area of your heart pine and see how it does after a month or so, but there’s a good chance the resin in the pine will bleed through. I would go with an oil-based, stain blocking primer instead. Good luck with your project

    Hi and thanks in advance,
    I am making a bookcase out of matched pine 1 by 6 tongue and grove. I buy scrap from the box stores when I can find it. This is raw wood, pre sanded and groved. Its coming out nice, but finishing is not my forte. Wife wants a matching color to our accent wall in the living room. Do I seal the wood first, then sand and then paint?

    Hi, we bought an older mobile home with knotty pine paneling. My problem is it smells old. I have replaced the carpeting and drapes and it still smells old. Is it the paneling? Would it help to get some sort of odor neutralizer spray or bite the bullet and paint?

    @patricia mattson: I think you are saying that it is your mobile home as a whole that smells “old” and not just the paneling.

    By your simple description of the smell it is impossible to know what your “old” smells like, so I will take a wild guess and say that what you are smelling is years and years of PEOPLE. We humans continuously emit gases and particulates and these organic products accumulate in our living areas. The gases are absorbed by the surfaces in the home and are re-emitted into the air you are breathing (and smelling). Likewise, the particulates (skin and hair cells primarily) break down with the help of bacteria and the bacteria emits odors that are characteristic of the decomposition of human cells.

    To see if this is true in your case you should thoroughly vacuum your ENTIRE mobile home with a good bag-style vacuum cleaner with a HEPA filter, and by thoroughly I mean every single surface in the home including floors, ceilings and duct work. When you are finished, go outside for 30 minutes or so to allow your nose to adjust to neutral odors. Then go back in your house to see if the “old” smell has been lessened. If it has, then you know that you’ve made a start at removing it from your home. Then, to remedy the situation you will need to repeat this exercise, supplemented by a thorough wipe-down of all non-porous surfaces such as appliances and countertops, once a month for about a year. In addition to removing the particulates the vacuuming pulls odors out of the surfaces much faster than they would outgas. And, whenever possible, open windows to allow fresh air to pass THROUGH your home. This will keep human odors from building up.

    Mobile homes are especially susceptible to the accumulation of odors because they have poor ventilation and it is typical to have a higher number of people per square foot living in them as opposed to apartments or houses.

    I have 5 doors with knots showing through the paint although I used a knot sealer the 1st time. This time to stop the bleeding I have drilled holes in the knots then sealed them with knot sealer & B.I.N paint sealer, I then fill the holes with wood filler & sand down, then paint all the door with the B.I.N paint then undercoat & gloss.
    I think this will cure the problem.

    I have kitchen cabinets that have a nice shape/cut, but the wood is dark pine with knots (doesn’t look like the same “knotty pine” my grandmother hand, but still…could be!) I’ve been told there is NO way to paint these a light color without the knots showing. Is this true?

    Last year I sanded down all the schellaced knotty pine walls in my rec room ,primered them with kiltz primer and then painted 2 walls white and the remaining walls taupe using latex semi-gloss paint. Alas! now the knots in the 2 white walls are bleeding back through.
    Today I visited 3 different paint stores to get info on how to correct the error.
    I decided to purchase a spray on shellac base primer-sealer-stain killer by ZINSSER (B_I_N). Can you please advise me if I have chosen the best primer to redo my stains. What is the best way to apply the primer and is it possible to only primer the stains and then paint over them when the primer is dry.
    Do I need to do any prep work on the stains before putting the primer on? Thank you for any assistance you can offer me.

    Knotty Pine is a beautiful wood. I’ve heard several things about knotty pine. I’d like to have it in my home. I’ve heard overtime the knots that are in the panel over time fall out leaving holes in the panel. Some people think it leaves a greater effect, others aren’t fond of it. What is the typical/common problems or facts rather about knotty pine?

    I commented in September 2012 about my pine cabinets. They are now painted a lovely shade of sage green, in keeping with the style of the home. I replaced the hardware with glass knobs and did some glass front cabinets for crystal glassware. It is GORGEOUS. No regrets!

    Just purchased a set of children’s furniture made of UNTREATED Pine that has not been sealed or painted. I wish to use these outdoors. I have ideas about painting various festive, bright themes….BUT….not sure how to begin so they last a few years. Do I seal with oil before painting? If so, what type do you recommend? Suggestions for paint also? I’m all ears…… :-) Thank you
