  • ✔️Item: Wood Repair Epoxy Putty
  • ✔️Size: 1 oz

For over 40 years, J-B Weld has been manufacturing high-strength adhesives, and the latest model is no exception. The highlight of this product is that it’s a two-part hand mixable putty stick that lets you repair any household wood all by yourself. Thanks to J-B Weld for this wood repair epoxy which is perfect for all types of household wood. 

Why Did We Like It?

What we absolutely loved about this epoxy wood filler is that it is specifically designed for DIY repairs. Unlike other epoxy wood fillers which are in the form of putty or pouring liquid, J-B Weld has done a great job in formulating a putty stick for ease of use. 

Furthermore, this putty stick allows you to repair all the wooden surfaces, challenging cracks and gaps without any professional help. Simply cut, knead, apply and wait for it to dry. This tiny 1-ounce package works particularly best for door and window frames. 

Moreover, it has a shear strength of 900 psi, which is pretty decent in our opinion. And the best part is, it cures within one hour. After curing, you can machine, drill, sand, file, and even paint it. 

What’s particularly pleasing is that this 1-ounce stick is powerful enough to conceal and repair the damages right in the first application. Plus, this heavy-duty epoxy will neither shrink nor rot. As such, it is highly durable. 

What Could’ve Been Better?

This epoxy wood filler is undoubtedly an excellent option, mainly because of its unique stick design, ease of use, and durability. And for that reason, this wood filler comes with an expensive price tag. However, considering the design and features it offers, it is totally worth the extra bucks. 

Pros
  • Hardens pretty quickly
  • Excellent for all household repairs
  • Easy to use
  • Holds screws efficiently
Cons
  • Slightly expensive

Whether you have to repair the exterior surfaces of your home or have a large renovation project at hand, this wood repair epoxy paste will deliver excellent results. As such, you can use this epoxy for both outdoor and indoor applications. 

Why Did We Like It?

If you ask us, the best part about this wood filler is the setup time of 30 to 40 minutes. Unlike other epoxy putties, which harden quickly, the PC epoxy paste gives you plenty of time to work with. 

The putty is tough and can withstand UV light, fresh and saltwater, and dry rot. This makes it perfect for outdoor applications as it will neither pop out nor crack by being exposed to harsh environmental conditions. 

Plus, the thick consistency of this putty makes it perfect for applications on overhead and vertical surfaces. Its peanut butter-like consistency means fewer drips and sags, and so it is highly versatile. You can use this to mend window sills and doors, fix railings and stairs, and fill cavities in damaged wood. 

What’s more, the tan color of this putty blends in beautifully with the wood. And, after it dries, you can sand, nail, drill, prime, and even stain it if you wish to. 

What Could’ve Been Better?

While testing, we did not come across any significant drawbacks. However, since it is epoxy wood putty, it is certainly not easy to clean. And so, we recommend you mix the two-part putty on some disposable surface. Apart from that, this putty paste works exceptionally well to repair the rotten wood. 

Pros
  • Plenty of setting time
  • Can withstand the elements
  • Doesn’t crack, pop out or shrink
  • Sandable and paintable
Cons
  • Cleaning is a challenge

Minwax has been producing top-notch quality products for years, and this 42853000 Wood Filler is no exception. This high-performing bonding wood filler is an excellent product as it repairs and mends all the cracks, defects on wooden surfaces. Moreover, you can use this product for both interior and exterior applications. 

Why Did We Like It?

Those who have used Minwax wood fillers can vouch for its quality. As far as Minwax 42853000 is concerned, we love its fast-drying formula. Not only does it set in a few moments, but it also allows you to sand within minutes after applying it to the surface. 

Furthermore, this wood filler is high in versatility, as it can be used for various surfaces. You can use this to fix the damaged wood floors and repair, restore and rebuild cracked wood. Also, you can use this filler as a powerful adhesive to fill hardwood floors, which is a bonus. 

What’s more, this filler also doesn’t shrink or crack, thanks to its solvent-based. And this is what makes it perfect for all your outdoor repairing needs. Plus, its cheese-like consistency makes it easy to use and highly durable. 

Also, it accepts stains without any hesitations, and cleaning is a breeze with just soap and water. Lastly, it allows you to mend all the cracks, holes, and defects without costing a fortune. 

What Could’ve Been Better? 

We were pretty satisfied with the overall results produced by Minwax Wood Filler. However, while testing the product, we noticed that the filler due to its thin consistency drips from the end of the putty knife. 

So, we recommend you use it in small quantities to avoid messing the surfaces or carpets around you. 

Pros
  • Sets within seconds
  • Ideal for heavy-duty applications
  • Doesn’t shrink or crack
  • Relatively easy on pockets
Cons
  • Filler drops off the end of the knife

Next up, we have another quality product from System Three. The SculpWood epoxy putty is an excellent choice for people who do not have much experience using epoxy wood fillers. This two-part epoxy resin putty is solvent-free, kneadable, and everything you’ll need for wood repairing and restoration tasks. 

Why Did We Like It?

The SculpWood Epoxy Putty does an outstanding job in restoring the worn-away wood and mending the challenging cracks. Kudos to SculpWood for formulating a kneadable resin putty instead of a wood filler product. You can knead it like bread dough into any shape you want. 

As such, this kneadable putty is highly versatile. You can use this to repair your window sills, door, fence, furniture, and other cosmetic defects. Plus, it is also usable on both interior and exterior surfaces, thanks to its waterproof formula. Although it is kneadable, it hardens as fast as the other epoxy wood filler, which is impressive. 

What’s more, it is tough and furnishes the surfaces with excellent adhesive strength. Not only that, but it is sandable and holds the paint, screws, drilling, and nails pretty well. The 1-quart can is decent enough for all your minor repair works and will last longer if you store it properly. 

What Could’ve Been Better?

We couldn’t help but notice a couple of downsides to this otherwise outstanding product. First, it takes slightly longer than 20 minutes to set. So, we recommend you work with patience for exceptional results. 

Secondly, because this moldable epoxy putty works pretty well in repairing rotten and chipped woods, it comes with an expensive price tag. 

Pros
  • Can be molded to any shape you want
  • Excellent for restoring worn away wood
  • Hardens pretty quickly
  • Easy to use and clean
  • Furnishes excellent adhesive strength
Cons
  • Takes a long time to dry
  • Slightly expensive
  1. Abatron WoodEpox

Our next product is perfect for all your heavy-duty tasks. For all your aging decks and rotten wood, there’s nothing better than Abatron WoodEpox Replacement Compound Wood Filler. This Wood Epoxy is easy to use and works well in large areas. It is an excellent product for all the DIYers and professional woodworkers. 

Why Did We Like It?

One of the best things about this product is that it perfectly restores the rotted and worn-away wood. You can use this for refilling and restoring any chipped wooden surface.

Furthermore, this filler has a slow drying time. This allows you to fill the cracks precisely and accurately without worrying about the putty drying away. Plus, it does not drip, which we absolutely loved about wood fillers. You can either apply multiple layers or spread in a single go. 

What is particularly impressive is that you don’t have to be a professional to use this for repairing your window sills or cabinet, for this epoxy wood filler comes with detailed instructions. And so, it is easy to use. 

What’s more, this epoxy wood filler dries as hard as a rock making it tool-able, sandable, and paintable. As such, this ensures the durability of the putty. Once applied, you don’t have to worry about the health of the wood. 

What Could’ve Been Better?

The Abatron WoodEpox bonds your rotted wood exceptionally well. However, the containers are pretty small as compared to other Abatron products which we bought earlier. For some, it might be an expensive deal. 

Plus, cleaning is quite a challenging task. We recommend keeping some rubbing alcohol handy to clean up the excess epoxy from the wood. 

Pros
  • Highly durable
  • Easy to use
  • Comes with detailed instructions
  • It doesn’t drip
  • Sandable, tool able and paintable
Cons
  • Small containers
  • Cleaning the epoxy is challenging

Epoxy Wood Filler Buying Guide

By now, you know the best 5 epoxy wood fillers that you can consider for repairing the window sills or the cracked cabinets. However, buying a wood filler isn’t a piece of cake. And so, simply knowing the best epoxy wood filler along with its pros and cons isn’t enough information. You need to be aware of a lot of factors that come into play. 

So, to help you choose the right epoxy wood filler, we have discussed all the important factors here. After reading this, we are pretty confident you’ll be able to choose the best one for your needs. 

  1. Type Of Wood Repair

While choosing an epoxy wood filler, you need to first keep in mind the nature of your task. There aren’t any one-size-fits-all epoxy wood fillers. A wood filler ideal for fixing large holes might not be a perfect solution for repairing furniture.   

If you have to fix large holes, you must go for a strong and durable wood filler. Meanwhile, for repairing cracks on your furniture, you will have to go for the one which will be easily sandable and paintable. 

  1. Viscosity

The next thing to keep in mind while choosing a wood filler is its viscosity or consistency. There are wood fillers manufactured in different viscosities to suit different needs.

The peanut butter-like consistency of the thick fillers makes it perfect for repairing overhead vertical surfaces, large holes, and gaps, for they don’t drip. Meanwhile, the thin viscosity fillers have watery consistency making them ideal for minor scrapes, chips, and surface damages on your wooden surface. 

We strongly recommend you consider the nature of the task and then decide which wood filler would be perfect for your repairing work.

  1. Interior Or Exterior

Believe it or not, the interior and exterior wood fillers aren’t made of the same component. So, you cannot expect an interior wood filler to do the job of an exterior one. An exterior wood filler must be resistant to UV rays, heat, water, termites, molds, and scratches. 

Plus, it should be long-lasting. And so, we strongly recommend you go with a product suitable for both interior and exterior use. 

Verdict On Epoxy Wood Filler
