Can You Use Wood Putty Outside?

Wood putty is a type of filler used to repair small holes, dents, and scratches in wood surfaces. While wood putty is typically used indoors, there are some types that can be used outdoors. However, it is important to choose the right type of wood putty for the job and to follow the manufacturer’s instructions carefully to ensure proper adhesion and prevent damage to the surface.

  • Purchase wood putty that is designed for outdoor use and is the same color as the wood you are repairing
  • Clean the area around the damage with a wire brush to remove any loose paint or debris
  • Apply the wood putty to the damaged area with a putty knife, pressing it into all cracks and crevices
  • Allow the putty to dry completely according to the manufacturer’s instructions, typically 24 hours
  • Sand the area smooth with fine-grit sandpaper, starting with 100-grit and working up to 220-grit if necessary for a completely smooth finish

Wood Putty vs Wood Filler? What is the Best for your Woodworking Project?

Does Wood Putty Last Outdoors?

Wood putty is a popular choice for repairing small holes and cracks in outdoor wood surfaces. While it is not as durable as other patching materials, it can last for several years if properly applied and maintained. When choosing a wood putty, be sure to select one that is compatible with the type of wood you are working with.

For example, there are putties specifically designed for use on pressure-treated lumber. Applying putty to damp or wet wood will also decrease its lifespan. To apply wood putty, first, clean the area around the repair site and then sand it smoothly.

Next, apply the putty according to the manufacturer’s instructions. Once dry, sand the area again until flush with the surrounding wood surface. Finally, seal or paint over the repair as desired.

Is Wood Putty Waterproof?

Wood putty is a type of filler used to repair damage to wood surfaces. It is also used to fill in small cracks and holes in wood. Wood putty is available in different colors, so it can be matched to the color of the wood surface being repaired.

Despite its name, wood putty is not actually waterproof. However, it is water-resistant and will not swell or shrink when exposed to moisture. This makes it an ideal material for repairing damage in areas that are subject to high humidity, such as bathrooms and kitchens.

What Happens If You Use Interior Wood Filler Outside?

If you use interior wood filler outside, it will not last as long as if you used an exterior wood filler. This is because the interior wood filler is not made to withstand the elements like exterior wood filler is. Over time, the interior wood filler will break down and crumble, leaving your repair job looking worse than before.

What is the Difference between Wood Filler And Wood Putty?

When it comes to minor wood repairs, many people are unsure of which product to use: wood filler or wood putty. Although both products can be used for similar purposes, there are some key differences between the two. Wood filler is a thick, paste-like substance that is used to fill in holes and cracks in wood surfaces.

It is typically made from a combination of sawdust and resin, and dries hard once it has been applied. Wood putty, on the other hand, is a pliable compound that can be used to fill small gaps and cracks in wood surfaces. Unlike wood filler, wood putty does not dry hard; rather, it remains somewhat flexible even after it has been cured.

One of the main advantages of using wood filler over wood putty is that the former dries harder and is more durable than the latter. This makes it ideal for repairing areas that will receive a lot of wear and tear (such as floorboards). Wood putty, on the other hand, is better suited for cosmetic repairs where flexibility is desired (such as filling in small cracks in furniture).

Another difference between these two products lies in their respective uses. Wood filler is typically used prior to painting or staining, while wood putty can be used both before and after these finishes have been applied. Additionally, because it dries hard,wood filler can also be sanded down once it has fully cured; this isn’t possible with wood putty.

How to Use Wood Putty?

Wood putty is a popular choice for many woodworking projects. It is easy to use and can be easily sanded and painted to match the surrounding area. Putty comes in different colors, so it is important to select the right color for your project.

Most wood putty is water-based, so it is important to follow the manufacturer’s directions when using it. Be sure to work in a well-ventilated area and wear gloves to protect your hands. To apply wood putty, simply scoop out some of the putty with a putty knife and spread it over the area you are repairing.

Use as much or as little as you need to fill the void or crack. Once the putty is in place, use a wet rag or sponge to smooth it out. Allow the putty to dry completely before sanding or painting.

Does Wood Putty Harden?

Wood putty is a type of filler used to repair holes, dents, and scratches in wood surfaces. It is usually made from a mixture of wood dust and a binder, such as latex, that helps the putty harden. You can buy pre-mixed wood putty or make your own using sawdust and glue.

To use wood putty, simply apply it to the damaged area using a putty knife or your fingers. Work it into the hole or dent until it is level with the surrounding surface, then allow it to dry for the amount of time specified by the manufacturer. Once dry, you can sand the area smooth and paint or stain over it if desired.

Wood Filler Or Putty for Nail Holes

There are a lot of ways to deal with small nail holes in wood, but which one is best? Should you use wood filler or putty? Here’s a look at the pros and cons of each option:

Wood Filler:

Pros: Wood filler is easy to apply and dries quickly. It can be sanded smooth once dry, and it accepts stains well.

Cons: Wood filler shrinks as it dries, so you may need to apply multiple coats to fill deep holes. It can also be difficult to match the color of your wood filler to the rest of your piece.


Pros: Putty takes longer to dry than wood filler, but it doesn’t shrink. This means that you can fill deep holes in one application. Putty is also available in a range of colors, making it easier to match your project’s finish.

Cons: Putty can be difficult to apply evenly, and it doesn’t always accept stains well. Once dry, putty is also softer than wood filler, so it may not stand up as well to wear and tear over time.


Yes, you can use wood putty outside! This type of putty is perfect for filling in small cracks and holes in wood surfaces. It is also ideal for repairing damaged wood or for creating a smooth surface before painting.
