Can Wood Filler be Used Outside?

In the past, most professional woodworkers would argue that wood filler wasn’t the right choice for exteriors. That’s because back then, the filler wasn’t flexible, and it’d crack if the wood either expanded or contracted. Moreover, if there was direct sunlight over it, chances are it’d shrink fast.

Luckily, that’s not the case anymore. Now, high-quality wood fillers such as the reviewed ones here are suitable for outdoor applications. Regardless of the sunlight, the filler won’t crack nor shrink. Even better, you can stain and paint over it if needed without any issues. So, there are different types of filler for wood, you just need to find the right wood putty or filler to use for exterior use.

Of course, the capabilities of the wood filler depend a lot on the brand’s quality. That’s why we’ve created the list of best wood fillers you can use for exterior wood repair, where we discuss only the top options worth your time and money. These products delivered long-lasting results in both inside and outside locations.

How Do You Fill Large Cracks in Wood?

First, you’ll need to buy a filler compound that matches the color of the wood. Worry not! We’ll help you with that. Once you get your preferred filler, it’s time to get to work.

• Step 1: Filling the Hole

There are two options for filling holes or gaps. If you purchased a filler stick, rub it over the crack. Then, use your finger to spread it as much as needed. However, if you use wood putty instead, you’ll need a putty knife or a chisel. Continue doing it across the wood grain until you overfill the crack with the filler.

• Step 2: Smooth the Filler

You have limited time, so make the best out of it by molding and flattening the filler as much as possible. Use the putty knife, a clean rag, or your finger to do it. If you use the rag, make sure it’s clean to avoid debris.

Then, you wait. The drying time varies depending on the filler, with some products requiring more or less than 8 hours. Check the label to know about the dry time.

• Step 3: Finishing

Use a fine grit to blend the racked area. Either 120 or 220 sandpaper would work too. Remove the excessive filler until it’s flat against the wood.

Factors You Need to Consider Before Buying the Best Exterior Wood Filler

Keep the following considerations in mind before purchasing your wood filler.

• Color

For better results, you’ll need to buy the filler that most resembles the color of the wood you want to repair. Fortunately, if you can’t find it, you can always mix different substances to get a look-alike shade that matches the cracked area.

• Single or Two-Parts

You’ll notice that, in some cases, brands offer two-part solutions instead of a single product. Those purchases include the filler and hardener in separate containers, and more often than not, purchases, including both of these products provide better results.

Of course, you could get a single product instead. It all depends on what you want to do and your preferences.

• Volume

Other than the color and the type, you also have to figure out just how much filler you’ll need for your projects. For smaller tasks, 6 or 8 oz will be enough. On the other hand, if you’re a woodworker and require more than that, you could aim for a couple of gallons instead.

• Drying Time

Most of the wood fillers listed here dry fast. However, you don’t want them to dry too fast, or else you won’t have enough time to mold as much as needed. Having said that, don’t go for a product that takes many hours to dry, either. The ideal drying time would be from thirty minutes to an hour.
