What wood filler do professionals use?

If you’ve ever tried to fill a hole or crack in wood, you know that it can be quite difficult to get a high-quality finish. After all, the material is often very brittle and prone to cracking as well.

But if you’ve never done any DIY projects before, this is something that takes time and practice to master. In the end, though, it’s worth it because nothing says “I love my home” like doing some simple repairs yourself! So what do professionals use? Let’s take a look:

What wood filler do pros use?

So what wood filler do professionals prefer? The answer is, that it depends. Some pros use putty, some use filler and some professionals use both.

So what you’re looking for is a product that is easy to sand, doesn’t shrink, and stays put after drying. It’s also important that the wood filler be able to withstand moisture so it can withstand rain or snow without drying out or chipping off.

What is the strongest wood filler?

There are several types of wood filler on the market, but these two are the most popular. Epoxy wood fillers are stronger and more durable than polyester fillers, but they’re also harder to sand down and paint over, so they’re best used for jobs that aren’t going to be seen.

Polyester fillers are flexible when cured and can be painted with a primer after curing.

For small projects where you need just a few small fills, it may not matter which one you use—but if you’re doing more than one project at once or working in an area where strength is important, then choosing the right type will help ensure your repair lasts as long as possible

What are the 2 kinds of wood fillers?

There are two basic kinds of wood filler: putty and filler. Putty is a softer material that can be used to fill small gaps in wood trim.

A filler is a harder material that can be used to fill larger gaps in wood trim. It’s important to distinguish between the two because their applications differ significantly depending on the size of the gap being filled, as well as its depth and complexity.

What’s the difference between wood putty and wood filler?

Putty is a soft, pliable material that’s easy to shape and can fill small gaps. It’s not as strong as filler, though, so it’s best for minor repairs.

A filler is a harder, stronger filler that you use for larger gaps in woodwork and furniture. Filler is harder than putty and won’t flex or bend like putty does; however, it’s still soft enough to get into small spaces with ease.

How thick can wood filler be applied?

The thickness of wood filler depends on the type of filler you use. Some types can be applied very thin, while others require a thicker layer to ensure that they are strong enough to support the weight of whatever surface you place on top of them.

You’ll also want to consider how much time and effort it would take for a professional painter or carpenter to apply the wood filler.

If they have their own tools and equipment, then it might not matter so much how thick your wood filler is applied—but if they’re using only hand tools and sandpaper, then a thick layer could make things more difficult for them when they’re trying to smooth out those rough edges.

Does wood filler get as hard as wood?

No, wood filler is not as hard as wood. It’s more flexible than wood and will change shape over time.

When you’re ready to sand your project down, you’ll want to wait until the filler has cured for a full 24 hours before doing so.

The curing process allows the moisture in the filler to evaporate out of it, leaving behind a harder outer layer that will resist chipping or breaking when sanded down in preparation for finishing your project with stain or paint. If you try to sand too soon after applying filler, it will likely crumble under pressure from your sander’s drum head.

To test whether a particular brand of filler has sufficiently cured for sanding purposes without damaging yourself (or others), simply run one finger along its surface; if its texture feels gritty like pepper or salt rather than smooth like fine sawdust then it’s probably ready!

How do you hide wood filler?

As a professional, you’ll want to make sure that you’re using the right tool for the job. Your best option is a putty knife. Not only are they versatile and easy to use, but they can also be used to apply and smooth out your wood filler.

Let it dry so you can sand it down before painting or staining over it! If you don’t like how dark your wood filler looks in contrast with your walls, simply paint over top of it!

How do you fill large gaps in exterior wood trim?

You will need to use a wood filler that is designed for exterior use. Make sure that it can be sanded and stained.

Professional contractors will often use epoxy fillers, which are the best choice when working on large gaps in exterior trim.

This is because they are very durable, so they won’t crack or chip like plastic fillers do after they dry out over time. Also, they can be stained and will not require paint to work their best!


In conclusion, wood filler is an important tool for professionals to use. It helps them repair woodwork and makes it look new again. The best wood filler can be found at hardware stores or online retailers such as Amazon.
