where to buy Bondo wood filler?

Bondo is a popular brand of auto body filler, but it’s also used for wood projects. Bondo is a two-part putty that adheres to the surface when mixed together.

In this article, we will cover everything you need to know about using Bondo wood filler, including what it is and how to use it properly.

Is Bondo a good wood filler?

Bondo is a good wood filler. It is not the best, but it’s more than adequate for most purposes. Bondo is not as strong as epoxy, but it’s easier to use and has less of an odor.

Bondo also isn’t quite as strong as polyester resin, but it’s still plenty strong enough for most uses.

What is the difference between Bondo and wood filler?

Bondo is a plastic filler that is used to fill holes in wood, while wood filler is a glue that can be used to fill holes in wood.

Bondo is stronger than wood filler and can also be used to patch up cracks. Wood fillers are less expensive than Bondo, but they are weaker and cannot repair large cracks or holes like Bondo can.

If you need to fix major damage on your deck or other wooden structure, then it’s best to use Bondo instead of wood filler because it’s stronger than traditional glue.

Can regular Bondo be used on wood?

Bondo wood filler is meant to be used on metal, plastic, and fiberglass. However, it can be used on wood if you want to fill a small crack or hole in your furniture or cabinet door.

If you choose to use Bondo for this purpose, it’s important that you use regular Bondo rather than other types of Bondo products such as fiberglass or self-leveling filler.

Regular Bondo has a higher viscosity than other types of Bondo products and this makes it stronger than the others.

If you decide to use regular Bondo on wood surfaces, make sure there are no large cracks or holes that need filling because regular bondo isn’t strong enough.

Also, keep in mind that regular Bondo will not last long when used on wood surfaces because they tend to shrink over time causing the filler material underneath them to fall out.

Which is better wood putty or wood filler?

There are two main types of filler: Bondo, which is a two-part epoxy, and wood putty. Wood putty is a single-part epoxy that requires no mixing and sets up in 10 minutes. It can be used on exterior or interior surfaces.

Bondo is ideal for filling cracks or holes in your car’s bodywork because you can sand the filler smoothly after it sets up and paint over it (provided you use quality primer).

Will Bondo wood filler crack?

Bondo wood filler is a great way to fill in small cracks in your furniture or other wooden objects, but it’s important to be aware of the fact that Bondo will crack under stress.

Because it’s made from polyester resin and asphalt, Bondo can be brittle; if you put too much pressure on the wood while applying it or if you apply too thick of a layer of Bondo on top of your existing surface, there’s a good chance you will end up with an unsightly crack.

As we mentioned above, cold weather can also cause cracking when using this product. The colder temperatures cause the polyester resin inside to contract (shrink), which causes cracks in its layout as well as distortion in its shape overall—and since most people don’t live next door to their local hardware store where they can pick up new supplies at any moment after experiencing such problems, this could lead them down quite an unfortunate path!

Humidity levels also play a part: When humidity rises above 50 percent during application time (or even before) then drying time tends toward being slower than normal—which means not only more work but also more chances for those pesky little crevices between grains coming out looking like zits instead!

What will Bondo not stick to?

Bondo can be used on any surface that is porous, such as wood and fiberglass. It will not adhere to polystyrene foam, polyethylene foam, or polyurethane foam. Bondo also won’t stick to polypropylene foam.

What is the strongest wood filler?

Bondo is a polyurethane resin that’s stronger than wood putty. It’s used to fill holes, cracks, and gouges in wood furniture and boats.

Bondo has been used by carvers too; it can be carved into a mold of an object you want to create an exact replica of.

If you have any questions about your project, look up the Bondo brand name on YouTube or Google for tutorials that show how to use it.

How long does Bondo wood filler take to dry?

In a dry, warm environment, Bondo will dry in one day. If you live in a humid climate, or if your Bondo was applied in winter and then left to sit through the spring and summer months, then it could take up to two weeks for the Bondo solution to fully cure.

The thickness of the Bondo being applied is also an important factor when determining drying time. If you’re using only enough wood filler to fill small holes and scratches on your furniture piece’s surface, expect those repairs to set faster than those requiring significant amounts of filling material (like large gouges).

This is because more mass means more molecules need bonding together; therefore it takes longer for this process of polymerization (or curing) to occur at lower temperatures without any other outside influences affecting how quickly that bonding happens.*


I hope this article has helped you to decide whether or not Bondo is a good choice for your project. It’s certainly one of the most popular options out there, but it may not be the best fit for everyone!
