Use PERMA FILL expandable wood filler to fill cracks and knot holes in wood deck and dock boards.  Creates a smooth finish for distressed wood before resurfacing with DeckRevive or DockRevive.

  • will not shrink
  • environmentally friendly, VOC-free
  • tools clean up with water

PERMA FILL (PermaCaulk) was developed as the only expandable crack and knot filler available on the market.  Latex based caulks tend to shrink and offer no permanent solution for filling cracks and knotholes.  PermaFill  is designed to properly prep wood structures before resurfacing.  It fills in cracks and knotholes, leaving behind a smooth finish.  Because of its expansive properties, PermaFill will lock into the distressed wood and stay in place for years.

The product contains an activating polymer resin that is mixed with a dry compound to produce a peanut butter consistency.  PermaFill should be applied and worked into cracks and knotholes using a putty knife.

This product sets quickly so that projects can be completed faster. It is pre-measured and all you need to do is mix the ingredients using a drill mixer in this convenient small bucket the product is packaged in.

The dry mix and polymer resin are conveniently packaged in a small 1 gallon plastic bucket that is shelf ready for retail establishments.  The product includes instructions with pictures that demonstrates proper mixing and applying to wood.

    I am about to restore my wood deck, and plan to use Perma-Fill to plug any knots/cracks (using Perma-Bond first to spot treat), then use Perma-Bond as a primer, and then finally I will be using the Deck Revive along with paint. I have already pressure-washed the deck and am waiting for 48 hours without any rain before I can move forward with the project.

    I have seen some conflicting information between the comments and instructions provided and wondering if you can please confirm the following?

    1. Does my old deck need to be sanded before using any of the products? I have tried to use a belt sander put it is having a very hard time taking the paint off although in other areas the paint is literally pealing off. Please can you let me know if I need to peel/sand as much as possible, or can I leave as is? Attached are pictures of the current deck which has a ton of peeling paint and is more worn in other areas.
    2. If I do need to sand, should I also do the same for all of the railings? Do you recommend a belt sander or an orbit/palm sander?
    3. If we have no rain for 48 hours and I start on Day 1 with Perma-Fill (with perma-bond first), I then need how much time approximately before then using the Perma-Bond to coat the entire deck?
    4. Once I apply the Perma-Bond, how long do I need to wait before applying the first coat of Deck Revive? I am hoping to finish all of this in 1 or 2 days, but again I need to be able to plan things around the fact we get a lot of afternoon Thunderstorms.

    Thank you for your help!!

      1. You will need to remove any loose/peeling paint first. You can cover the paint that is not peeling and is intact to the wood.
      2. See above. Any sander will work.
      3. As soon as the fill is dry.
      4. Permabond and Deck Revive need to go on the same day. The fill can go on any day prior or the same day, it just has to be dry before applying the bond.

    How dry does the wood need to be before using this product? It's raining today and I had wanted to use it tomorrow. Also, how long does it need to set before priming it?

    Will concrete revive work on a driveway with car traffic on it? (plus the UV/and water stress?)

    Hi, I have some areas with wood rot in my deck. What's the most recommended way to fill large gaps? Should I use something like wood hardener before perma fill? How big is too big of a hole not to use perma fill?

      It will work on areas that are up to 1 inch deep. Use a putting knife. Wood hardener will not work for rot.

    I have 2 x 6 boards on my deck and I have a large hole from rot. The rot has been removed and I now have a hole that is 3" wide and over 1" deep. Can I use Permafil to fill the hole?

    Can the perma caulk be used to fill old screw holes when re-dong the deck ? Some of the holes could be up to 3/8" dia.

      I may peel eventually int those areas but should most likely be okay.

    1. What is the life of PermaFill once it has been mixed?<br>2. Is PermaFill sandable?<br>3. Is PermaBond usable under any latex solid color stain (I am considering using on cedar siding)?

      <p>1. Couple of hours.</p><p>2. Best to not sand.</p><p>2. The PermaBond can be used as a primer for most paints but best to ask the manufacturer of the paint to see if a primer does work with their product.</p>

    To expand on the previous question, you say to spot treat cracks with PermaBond , then fill cracks with PermaFill. Does this also apply to counter-sunk screw holes? Also, my deck is very large and will take longer to complete all these steps. Can I fill the cracks/screw holes with PermaBond and PermaFill now, then wait a month or two for better weather to apply PermaBond and DeckRevive to finish the deck? Thanks!!

      Any areas that you want to apply PermaFill, you will need to spot treat first with Permabond. It would best to not wait a month between. Try to do as soon as possible.

    I ordered the Deck Revive and Perma Bond but then I saw the Perma Fill. My deck is really old and weathered with deep grooves. Should I get the Perma Fill and start with that? If so, will the Perma Bond adhere to the Perma Fill? Meaning should I 1) Perma Bond 2) Perma Fill 3) Deck Revive. Thanks in advance!<br><br>-Amber

      This would help to fill grooves. Spot apply the Permabond in those grooves first. Let dry and apply Permafill. Let dry and apply the Permabond to all the wood before using the Deck Revive.

    To apply this to an approximately 200 sq ft weathered deck. I will need the deck revive kit, the perma bond, the perma fill, and anything else other than a roller, possibly drop cloth, tape and a brush?

      You need a gallon of gloss acrylic latex paint pre-tinted&nbsp;to the color you choose. A 5-gallon drill&nbsp;mixer that fits on a drill as well.

    Can this product be used with stain only to fill in big cracks (i.e. not with Deck Revive kit?)

      It will not blend to match with a semi-transparent stain. It will work if you use a solid color stain to cover it.
