Wood Filler vs. Wood Putty: What’s the Difference?
When working on woodworking projects, you often encounter terms like “wood filler” and “wood putty.” These materials are essential for fixing imperfections, but they serve different purposes. Understanding the differences can help you choose the right product for your project, whether you’re repairing furniture, fixing up window sills, or patching up floorboards. Let’s dive into the details of wood filler and wood putty, exploring their characteristics, uses, and how they can make your woodworking projects a success.
Understanding Wood Filler
Wood filler is a versatile material used to repair holes, dents, and scratches in wood. It’s usually made from a combination of wood fibers, cellulose, or gypsum, mixed with a binder that hardens after application. Here’s a closer look at its features:
Composition and Types
Wood filler comes in different types, each suited for specific tasks:
- Water-Based Wood Filler: This type is easy to clean with water, dries quickly, and is environmentally friendly. It’s ideal for indoor projects.

- Epoxy Wood Filler: Offers exceptional strength and is suitable for large gaps and structural repairs. It requires mixing before use.
Properties and Benefits
Wood filler is designed to blend seamlessly with wooden surfaces, making it a popular choice for:
- Hardening: Once applied, it hardens, providing a sturdy base for sanding, painting, or staining.
- Paint and Stain Compatibility: You can paint or stain wood filler to match the surrounding wood, which makes repairs almost invisible.
- Versatility: It’s suitable for various wood types and can fill both small and large imperfections.
Exploring Wood Putty
Wood putty, often confused with wood filler, is another product used for wood repair. However, it has distinct characteristics that set it apart:
Composition and Types
Wood putty is typically made from a mixture of oil-based compounds or plastic. Here are some common types:
- Oil-Based Wood Putty: Contains linseed oil or similar materials, making it pliable and long-lasting.
- Latex-Based Wood Putty: Easier to clean with water and suitable for indoor projects.
Properties and Benefits
Wood putty is known for its flexibility and is best used in scenarios where the wood may expand or contract. Its benefits include:
- Pliability: It remains flexible over time, making it ideal for outdoor use where temperature changes can cause wood to shift.
- Color Matching: Available in various wood tones, it blends well with stained or finished wood surfaces.
- Ease of Use: No mixing is required, which makes it convenient for quick touch-ups.
Key Differences Between Wood Filler and Wood Putty
While both products aim to repair wood, they serve slightly different purposes. Here are the main differences:
Application Areas
Understanding where to use each product can help ensure the longevity and appearance of your repairs:
- Wood Filler: Best for unfinished wood and areas that will be stained or painted. Ideal for filling large holes and deep scratches.
- Wood Putty: Suitable for finished wood and minor touch-ups. It works well on surfaces that have already been painted or stained.
Drying and Hardening
The drying and curing process varies between the two materials:
- Wood Filler: Hardens completely, providing a solid surface that can be sanded and shaped.
- Wood Putty: Does not harden completely, which allows it to remain flexible and adapt to changes in the wood.
Environmental Suitability
Consider the environment where the repair will take place:
- Wood Filler: Suitable for indoor repairs and areas that need to be painted or stained.
- Wood Putty: More appropriate for outdoor use due to its flexibility and resistance to weather changes.
How to Choose Between Wood Filler and Wood Putty
Choosing the right product depends on several factors, including the type of wood, the nature of the damage, and the desired finish. Here’s how to make an informed decision:
Assessing the Damage
Start by evaluating the damage to determine the best product:
– For small dents and scratches on finished wood, opt for wood putty.
– For larger holes or structural damage, choose wood filler for its strength.
Considering the Finish
Think about the final look you want to achieve:
– If you plan to paint or stain the area, wood filler is a better choice due to its compatibility with finishes.
– If the wood is already finished, use wood putty for a seamless repair that matches the existing color.
Environmental Conditions
The location of the wood can also influence your choice:
– Use wood filler indoors where stability is crucial.
– Choose wood putty for outdoor projects where flexibility is important.
Application Tips for Wood Filler and Wood Putty
Applying these products correctly ensures a smooth and lasting repair. Here are some tips to help you get the best results:
Applying Wood Filler
1. Clean the area to remove dust and debris.
2. Use a putty knife to apply the filler evenly.
3. Overfill slightly to account for shrinkage as it dries.
4. Allow it to dry completely before sanding.
5. Finish by painting or staining to match the surrounding wood.
Applying Wood Putty
1. Clean the surface to remove any dirt or residue.
2. Use your fingers or a putty knife to press the putty into the defect.
3. Smooth it out to ensure an even surface.
4. Allow it to set, and then gently wipe away any excess.
Common Mistakes to Avoid
When using wood filler or wood putty, avoid these common pitfalls to ensure professional results:
Using the Wrong Product
Choose the correct product based on the type of wood and the nature of the repair. Using wood filler on finished surfaces or wood putty for structural repairs can lead to unsatisfactory results.
Over-Sanding
Be cautious when sanding wood filler. Over-sanding can create uneven surfaces or remove too much material, compromising the repair.
Skipping the Drying Time
Both materials need adequate time to dry and cure. Rushing the process can weaken the repair and affect the final finish.
In the world of woodworking, understanding the differences between wood filler and wood putty can make all the difference. By selecting the right product for your specific needs, you ensure your projects are not only visually appealing but also durable and long-lasting. Whether you’re dealing with indoor furniture or outdoor structures, knowing when to use wood filler or wood putty is a vital skill for any woodworking enthusiast.
Frequently Asked Questions
When should you use wood filler instead of wood putty?
Use wood filler when you need to fill holes, cracks, or imperfections in unfinished wood. Wood filler is ideal for situations where you plan to sand, stain, or paint the wood surface afterward. It hardens and can be sanded smooth, making it a great choice for repairing wooden furniture, floors, or any wood surface that needs a seamless finish.
Is wood putty suitable for outdoor use?
Wood putty is not typically recommended for outdoor use because it does not harden completely and can be affected by weather conditions. It remains flexible, which can be beneficial for indoor applications on finished wood surfaces that may expand and contract slightly. For outdoor projects, consider using an epoxy-based wood filler that can withstand the elements.
Can you stain or paint over wood putty?
Staining or painting over wood putty can be challenging because it does not absorb stains like wood filler does. Wood putty is designed for use on finished wood and usually comes in colors that match common wood finishes. If you need to stain or paint the area, wood filler is the better choice as it can be sanded and colored to blend seamlessly with the surrounding wood.
How do you apply wood filler and wood putty?
To apply wood filler, clean the area to remove dust and debris, then use a putty knife to press the filler into the hole or crack. Allow it to dry completely before sanding it smooth, and then finish by staining or painting. For wood putty, simply press it into the defect on a finished wood surface with your fingers or a putty knife, smoothing it out as needed. Wood putty does not require sanding and is ready for use without additional finishing.
Do wood filler and wood putty work on all types of wood?
Wood filler and wood putty are versatile but have different applications. Wood filler works well on unfinished wood and can be sanded and stained to match various wood types. Wood putty is best for small repairs on finished wood surfaces. Choose the product that suits the state of your wood and the intended finish.
