does wood filler work?

Wood filler is a great solution for repairing small holes and cracks in wood. It’s also perfect for filling any gaps between the edges of two boards before painting them. But how well does it work? And can you paint it?

I’m going to tell you everything you need to know about using and working with wood filler, plus answer some common questions I get from my readers.

Is wood filler any good?

Yes, wood filler is a good way to fix small holes in wood. But don’t get your hopes up—it won’t work on large holes or deep ones.

Wood filler is perfect for fixing furniture, doors, and floors. It’s not recommended for filling large holes because it can crack over time or be difficult to apply properly without cracking anyway (but check out this handy tip).

If you’re looking for something that can fill larger voids in woodwork, try polyester resin instead!

How big of a gap can wood filler fill?

You can use wood filler to fill small gaps in wood, but not large ones. The best way to tell if your gap is big enough for wood filler is by looking at the two pieces of wood you want to join together.

If there’s even a little bit of space between the two pieces, then it’s more than likely too wide for wood filler to fill it.

If you have a large gap between your boards and are wondering what else you can do besides using a nail or screw, here are some suggestions:

  • Use clamps instead of screws or nails! Clamp them together until they dry and become one solid piece again. You don’t need any tools like drills or hammers; just clamping will work fine!

Is wood filler as strong as wood?

Wood filler is not as strong as wood, so if you use it to fill large holes in your project, the wood may eventually break through.

It’s a good idea to reinforce any area with a more permanent solution. For example, if you’re fixing a crack or hole that extends from one side of your work surface to another and it’s too big for wood filler, consider filling only the damaged area with your chosen material (plastic resin or epoxy putty come to mind).

Then apply some fast-drying glue over that patch before using another piece of wood veneer on top (painting this glue will help it adhere better).

If possible, consider using screws or bolts instead of nails if they will go through both surfaces without splitting them apart during installation; this way there won’t be any risk of peeling off old adhesive when removing those pieces later on.”

Is wood filler permanent?

You can paint, sand, and stain over wood filler.

Painting over wood filler: If you’re planning on painting your project afterward, be sure to use a primer first.

This will help seal the surface of the wood and prevent any bleed-through when you paint over it with your final color choice.

Sanding over wood filler: You don’t have to wait until after painting or staining before sanding; this is normal practice if you’re going for a distressed look.

However, keep in mind that because of its texture (and possibly because it will be heavier than regular drywall joint compound), it may take more effort to smooth out a rough surface after applying drywall joint compound than it would if using regular drywall spackle!

Is it better to use wood filler or caulk?

If you have a small hole, the answer is caulking. Wood filler will only work if you have a large gap to fill.

Caulk is also better for outdoor use, while wood filler should be used indoors. When it comes to gaps between materials, caulking works well for wider gaps but not as well for narrower ones (less than 1/4 inch).

What’s best to fill holes in wood?

  • If the hole is small, use wood filler.
  • If the hole is large, caulk would be a better option.

Both are permanent and can be painted to match your wall color!

Can you fill large holes with wood filler?

Yes, you can fill a large hole with wood filler.

It all depends on the size of the hole. If it’s too big, you’ll need to use a different solution. Wood filler is best for small holes and cracks in furniture, but if your problem is more severe than that—like if you’re looking at an abandoned tree stump in your yard—you may want to call in professionals who are better equipped for such tasks.

Can I paint over wood filler?

Yes, you can paint over wood filler. You’ll need to sand it first, however. The best way to do this is with coarse sandpaper (80-grit) and a power sander.

Then you should prime the surface with a coat of primer and let that dry thoroughly before applying multiple coats of paint—you want your final product to be smooth and even so that painting will be easy as pie!

Conclusion

As you can see, wood filler is a good option for filling small holes or cracks in wood. It’s also useful for patching larger holes if you want to make them invisible.

However, it’s not a permanent solution and will eventually need to be replaced with new material.

You should always use your best judgment when deciding whether or not to use wood filler on an item before applying any type of paint or finish over the top of it!
