Does Wood Putty Get Hard?


Wood putty is a popular woodworking material because it is versatile and can be used for a variety of applications. One question that many people have about wood putty is whether or not it gets hard over time. In this blog post, we will explore the answer to that question and provide some tips on how to make sure your wood putty stays in good condition.

Does Wood Putty Get Hard?

Wood putty is used to seal holes and cracks in wood. It is also known as plastic wood or wood filler. Wood putty doesn’t become fully hard but it will dry. After it dries out, but the process of drying depends on several factors such as temperature, humidity, and thickness of the layer that you are using for filling purposes. If you have applied a thick layer of wood putty, it will take more time for the product to dry. In most cases, wood putty becomes hard enough to be sanded within an hour or two. However, if you are working in a humid environment, then the drying process may take longer. You can speed up the drying process by using a hair dryer or a heat gun.

Some people use wood putty to fill the gaps between the boards in order to give a more polished look to their woodworking projects. In this case, you must be careful not to over-apply the putty because it will be difficult to sand it later on. It is also important to allow the putty to dry for a little longer before sanding it.

You can put wood stain on top of the dried putty, but you must first make sure that the surface is smooth and free from dust particles or other contaminants. You can use a soft cloth to remove any dirt or grime from the wood. You may also need to use a hand sander to remove any high spots from the surface of the wood.

If you are using wood putty for filling large holes, then it is better to allow it dry overnight before sanding and staining. If your project requires staining or painting, then you should wait at least two days after applying wood putty before applying these finishes. This will ensure that the wood putty is completely dry and has hardened to its maximum level of hardness.

If you are not sure whether wood putty will harden or not, then you can try it out on a small area first. You should apply the product to a piece of scrap wood and wait for a few hours to see if it dries out and becomes hard. If the putty does not seem to be drying, then you can use a hair dryer or a heat gun to speed up the process. You should also keep in mind that wood putty comes in different colors, so you may need to test different products before finding the one that works best for your woodworking projects.

Does Wood Putty Ever Harden?

There is a lot of debate on whether wood putty ever hardens. Some people say that it does, while others claim that it never fully dries or cures. The main issue seems to be the type of wood putty used – some products seem to cure better than others. If you are using a high-quality putty, it is likely to harden over time. However, if you are using a cheaper product, it may never completely dry.

One way to help the curing process is to apply heat. You can use a blow dryer or even a heat gun to help the putty cure faster. If you are having trouble getting the wood putty to cure, you can use a wood putty hardener.

Is There A Wood Putty That Hardens?

There are a few different types of wood putty, and some of them harden. However, there is no one-size-fits-all answer to this question, as the type of wood putty and the hardness of the surface it’s applied to both play a role in how long it takes for the putty to cure.

Some types of wood putty include:

  • Polyester Putty
  • Epoxy Resin Wood Filler
  • DAP Plastic Wood Latex Based Wood Filler (Popular Product)
  • Elmer’s Products Inc. E89046 Carpenter’s Color Change Wood Filler, 16-Ounce, Natural (Popular Product)
  • Titebond III Ultimate Wood Glue, 16-Ounce Bottle

If you’re looking for a wood putty that will harden relatively quickly, an epoxy resin filler may be the best option. This type of putty is typically used when a high level of strength and durability is required, such as when bonding two pieces of wood together.

The most popular product brands available on the market today are Minwax and Elmer’s Products Inc., which have a wide range of products to choose from. Both companies offer different types of putty that harden at various speeds depending on their intended use case scenarios (e.g. indoor vs outdoor, repair vs construction, etc.).

How Long Does Wood Putty Need To Dry Before Sanding?

Once the wood putty has dried, it is time to sand it. However, you will have to wait longer depending on the type of wood putty that you use.

Oil-based wood putties dry in about one hour, but then can take up to 24 hours before they are ready for sanding.

Water-based fillers dry in about half an hour, but unless you are working with a fast-drying product, it will take between two and four hours before they are ready for sanding.

After that, the wood putty is hard enough to be sanded like any other part of your project.

How Long Does Wood Putty Last?

Wood Putty takes between 12 hours to 72 hours to dry. The drying time depends on the type of wood putty you use, and how thickly you apply it.

With oil-based wood fillers, the thicker the application is, or if there are multiple layers of different colors applied together (e.g., light brown over dark red), then it will take longer for the wood putty to dry.

Thin applications or those with a single color will take less time to dry.

Once the wood putty has dried, it becomes hard and can be sanded down if needed. It is best to wait at least 24 hours before doing any sanding so that you don’t damage the wood putty.

I will always have a special place in my heart for woodworking. I have such fond memories working on projects with my parents on the weekends in the garage growing up. We built tables, shelves, a backyard shed, 10' base for a water slide into the pool, 2 story fort playhouse with a fire pole, and so much more. This woodworking blog allows me to write helpful articles so others can enjoy woodworking as much as we have.
