How To Use JB Weld to Restore Wood?
JB Weld is easy to use on wood to repair, restore and fill gaps and cracks. It increases the durability of the wood and wood resistance against moisture and other elements.
There’re 2 main JB Weld products you can use on wood for various tasks like restoring wood, repairing wood, filling gaps and cracks wood, and more. They are,
- JB Weld Wood Restore Liquid Hardener
- JB Weld Wood Restore Premium Epoxy Putty
So, let’s have a look at how to use JB Weld Wood Restore Liquid Hardener and Epoxy Putty on wood to restore properly.
Supplies you will need,
- JB Weld Wood Restore Liquid Hardener
- JB Weld Wood Restore Epoxy Putty
- Rotted wood or more
- Screwdriver or paint scraper
- Sandpaper or sanding block (80 or 100 grit)
- Fine grit sandpaper (180 grit to 220 grit)
- Tack cloth
- Paint or wood stain
- Latex gloves
- Spreader or mixing stick
Here’re the steps you need to follow to restore wood using JB Weld Liquid Hardener and Epoxy Putty,
- Dry and clean the wood
- Remove rotted area
- Seal wood with JB Weld Liquid Hardener
- Let it dry and Cure
- Mix and prepare JB Weld Epoxy Putty
- Apply JB Weld Epoxy Putty
- Let it dry and cure
Let’s discuss each of the above steps separately to get a clear idea of restoring wood with JB Weld.
1. Dry and Clean the Wood
The wood must be clean and completely dry before removing the rotted area. Otherwise, it’s difficult to remove the rotted areas from the surface. First let the wood completely dry out by keeping it in a dry, moisture-free environment.
If you live in a dry climate, this will take a few days, but for the people who live in a wet climate can take around 2 – 3 weeks. Airflows, and sunlight, help to eliminate moisture from the wood and dry out, especially the rotted area.
Once the wood is completely dry, clean it using a lint-free soft cloth to remove dust and debris. Never use soapy water or any other solution when cleaning because the wood needs to be in dry mode.
2. Remove The Rotted Area
Once the wood is completely dry, take the screwdriver or paint scraper and carefully remove the rotted area. By removing the rotted area, the drying process of the wood will be much faster.
If the wood is still not completely dry out, you can use a heat gun to dry out to dry them manually.
All the impacted wood fibers, loose and unstable wood should be removed with a screwdriver or scraper. If any remained on the surface while we are applying the JB Weld, that’ll cause so many troubles because rotted areas don’t hold them well.
When removing the decayed, very soft or loose wood keep the wood always dry. Once you’re done removing the impacted areas, clean the wood well to get rid of dust, dirt, or loose paint residue.
Likewise, proper surface preparation should be done before using JB Weld on wood to get the maximum out of it.

3. Seal Wood with JB Weld Liquid Hardener
Now shake the JB Weld Liquid Hardener bottle well and apply it to the impacted area using the paintbrush. There should be no rotted areas anymore when you’re applying to JB Weld.
When you’re applying JB Weld Liquid Hardener on wood, don’t dry to thin the liquid. Thick coats help to cover up the wood well and make a strong and tight bond with the surface. Saturate and soften wood thoroughly with JB Weld Liquid Hardener without missing any spots.
Apply several coats of JB Weld Liquid Hardener until you get a shiny glossy surface with an extra strong bond. But make sure to let the previously applied coat dry out completely before applying another coat of JB Weld Liquid Hardener on top of it.
4. Let It Dry and Cure
After applying several coats of JB Weld Liquid Hardener, let the wood dry and cure completely before moving on to the next step. Usually, JB Weld Liquid Hardener hardens and dries within 2 – 4 hours.
After applying JB Weld Liquid Hardener let it dry and cure for about 8 hours. Once the JB Weld coats are fully dried and cured, clean the surface well and move on to the filling process with JB Weld Epoxy Putty.

5. Mix and Prepare JB Weld Epoxy Putty
While the JB Weld Liquid Hardener coats are drying out you get enough time to prepare and mix JB Weld Epoxy Putty before moving on to the application step.
Make sure to seal the wood first with JB Weld Liquid Hardener or Premium Liquid Epoxy before applying JB Weld Epoxy Putty because there should be no rotted areas and the surface needs to be well prepared to stick wood putty well on to the surface.
Wear gloves and mix equal amounts of Part A and Part B Epoxy Putty using a 1:1 mixing ratio. Mix both parts well using the mixing stick or by gloved finger until uniform color appears.
Once you get the uniform color by mixing A, and B parts using a 1:1 ratio, you’re good to move into the application step.
6. Apply JB Weld Epoxy Putty
Now apply prepared Epoxy Putty to the impacted areas and fill evenly without missing any spots. The wood needs to be completely repaired. Therefore, shape the wood putties using your hand and shape them before filling the gaps and cracks of the wood.
Press the Epoxy Putty firmly when filling to get the surface as you want. You should do the application process without leaving Epoxy Putty for too long because it tends to harden quickly. Apply wood putty until you get the desired appearance of the wood.
7. Let It Dry and Cure
Once you’re done with applying wood putty and get the desired appearance as you want, let JB Weld Epoxy Putty hardens and dries for 2 – 4 hours.
After leaving it for 2 – 4 hours, Epoxy putty is completely hardened, and it won’t crack or shrink. After it is fully dried and cured you can sand, drill, or screw the surface with no issues.
For better protection, I recommend applying wood stain or paint once you’re fully done with the wood restoring process with JB Weld products.
You can apply any type of wood stain evenly throughout the wood, including the restored areas without making any wood stain mistakes.
That’s how you should restore rotted wood with JB Weld.
How To Remove JB Weld from Wood?
Usually, it is difficult to remove JB Weld from wood once it is fully hardened and cured. But you can remove JB Weld from wood by heating it above 6000F maximum threshold temperature. It will get soft around the threshold temperature level. But heating JB Weld to extreme temperature can damage the wood and you should do this carefully without damaging the wood.
Other than that, use an angle grinder to remove JB Weld from wood. this also should be done carefully without damaging the wood underneath.
Now you have a clear idea of using JB Weld on wood. So, let’s answer some frequently asked questions to see how JB Weld works on wood.
How Long Does JB Weld Take to Dry on Wood?
JB Weld takes 2 – 4 hours to dry on wood. if the area is well ventilated, JB Weld dries quickly. Drying time can differ according to the environmental humidity and the dryness of the wood. This is why drying is so important before applying JB products to wood.
What Is the Cure Time of JB Weld?
JB Weld cures within 2 – 4 hours. In my personal experience, it usually cured properly 6 hours after the application. During this time the wood should not get in contact with water, dust, or any other elements.
Once the coats are fully cured, they can sand, stain, paint, and drill without shrinking or cracking the surface.
Staining and painting are possible once the JB Weld Wood Restore is completely dried and cured.
