Deck Board Hole Repair

Filling in holes that have formed on your pressure treated deck boards is an approachable project for any homeowner. I will walk you through a couple examples to help you pick the right product and tools reducing the amount of time spent on this project and get the results you want.

I’ve done this a lot of times. If you use a multi tool to clean out the moist dry rot and use the liquid Rot Stop you will end up with a longer lasting repair.
If the hole is all the way through, use the multi tool to create a place for new wood or install a mesh screen to hold the Bondo. Make sure to use the dry rot killer before the Bondo. You can also use a good deck primer after the rot killer.

Good tips and thanks for sharing. I am repairing a few rotted parts and filling a few bolt holes from the old gazebo that was taken down. I will put wood hardener first over the rotted wood and then do this. Thanks for showing. I have used Bondo on my countertop before I did a 2part epoxy finish - great stuff.

Thank you for this! We have a small hole, sort of a splintered off spot on the side of one board in the middle of our deck from our movers and I was afraid we were going to have to replace the whole board. It’s also on the edge of the board so thank you so much for the tip on contouring with tape! I feel much more confident on fixing this now. This is the first time I’ve ever took on a project like this on my own. Restoring the entire thing and it was a bit daunting at first.

Hi....I live in a log home and it was time for a re-stain. I had a sand blaster company come in and blast the old stain off. Then there were a few areas that had rot. I cleaned them out like you did on your deck and then I used automotive Bondo simply because i never knew wood bondo existed at that time. I put the mixed Bondo in plastic ziplock bags and cut the tip out of one of the corners and filled the open holes in my logs like a icing bag. Worked well and if it hardened up before i got it out it was easy to just get rid of the bag and no mess. I did not have to use much of a trowel or spreader as I was sandng with a orbital sander. After i sanded the logs it matched perfectly to the sand blasted logs and the best part was it took the color of the newly applied log stain and was hard to tell it was repaired.

Nice job, happy you showed how to use the bondo & also how fast it can set up!

Scott, you're a superior instructor. No one's videos are as worthwhile as yours. Yours are the only ones anyone needs to watch for tutelage on home repairs.

Fantastic product. I used it on a couple of outdoor door jambs and worked great. I used much less hardening paste though and gave lot of time to work with. Great video. Thank you for sharing

I used PC Woody 2 part wood epoxy with very good results on my old outdoor deck last year. I removed the dry rot and let it dry thoroughly before I painted on several coats of wood hardener. I let the hardener dry thoroughly, before I filled with epoxy. My deck has a solid color stain so I finished with a coat of stain which blends it all in. The epoxy is holding up very well in a harsh climate even with constant wet weather and freeze, thaw cycles this Winter.

I’m rewatching this video. Thank you again for a great explanation

Awesome video! The two part bond is a great filler to use.

[joshgeorge]

genius tip for the curbed parts of the board !!

I have used this and I still use it. I filled minor natural wood cracks to prepare my new picnic table for stain and clear coat. My table is 10' long using (5) 2" X 12" boards. I have not had a problem with knot hole filling but I have saw 'aged' shrinkage of material in cracks I filled, requiring another spread to fill them cracks. I do like it and will continue to use it, but, remember, it's not bullet proof. Also, as I see the morning dew beading on top of my finished filler, I now wonder how it handles the stain. They state on the can that it does well with stain, but, we will see. Great video man!

A have a similar sized hole on a rounded wood floor board. I was going to use loctite with their expandable material but now that I see this wood filler, I think I'll try this first. Hopefully it will stand against summer heat

Great video: told me exactly how to use the product without a lot of preliminaries or extraneous jibberjabber. Thanks!

[tarynsanmartino]

Nice. Working on mine now and found this very helpful. I have exterior wood filler and was wondering how well it would work and also the different apps. for it in this project.

[MeHere]

Timely video. Today I’m going to use Bondo wood rot repair, then the Bondo wood filler on a few areas of my shed tongue and groove siding boards. I’m only going to mix very small batches and use less hardener. Wish me luck! Update: for my project, this dries too quickly. I hate sanding! Nextime I’ll use something that allows me to work at smoothing it out before drying.

[axelbrode]

I've used wood filler inside of Kitchen cupboards that the previous owner had drilled holes in the shelves (?) Light sanding then white paint. Now when visitors are looking for a glass or cup they can't see the damaged areas. I put tape under the cabinet to hold the filler until dry, then removed it.

thanks for sharing this project with us! Keep it up!

[peterbullen]

I have tried all sorts but still feel old sawdust and PVA glue works really well,

Gorilla wood filler...doing a freshly installed deck, but wood has a lotta knots, so gonna treat them all, the deck needs to cure till NEXT spring before it gets painted, so I hope it all goes good, couldnt afford really nice deck boards, so gonna do what I gotta do! Thank you for the how to, sorta same as what I thought, but double checking myself, I'll be 70 in July, have done a ton of decks thru the years, and lumber quality this time on fixed income, deck is 64'x24.5' Not a little project to pull up and replace all my decking, redo stringers, steps that span a 16' drop to ground...not an easy deal...and my lumber supplier had wood that had SO MANY KNOTS, geez...but doing what I can with what I have!
