Woodworking Putty


Woodworking putty is a type of epoxy or putty adhesive that comes in a range of colors and is used to help fill gaps, cracks and other imperfections in wood. Woodworkers use woodworking putty to smooth out uneven spots on the wood surface, creating a uniformed look which can enhance the appearance of any finished product. It also aids with holding joints together securely and increasing the longevity of them.

By filling these imperfections and cracks, more materials are also able to be recycled during the production process while also making it easier to paint over, stain or varnish the same surface. In addition, it can help reduce problems such as bulging or splintering when placed between two surfaces that will come into contact with each other frequently. It’s important to note that this type of filler can sometimes shrink once dried so application should be done carefully according to manufacturer instructions.

Lastly, some types of woodworking putty are readily available at most hardware stores in order for both professional and novice craftsmen alike to conveniently access these materials and start improving their project’s finish quality.

Benefits of Using Woodworking Putty and When to Use It

Woodworking putty is a versatile product used to repair small damages and fill imperfections in wood surfaces. The benefits of using woodworking putty include filling small holes, covering nail heads, sealing chips and cracks, smoothing rough edges and repairing wood rot. It can be applied easily with a putty knife, comes in several colors to match finishes and can be sanded for a perfect finish.

When to use woodworking putty depends on the situation you’re faced with. Use it to fill gaps between trim pieces, such as baseboards and crown moldings, or holes left by screws on furniture. Another common use case is when fixing hard-to-replace surfaces; like window frames, cabinet doors or wall paneling. Woodworking putty can also be used to cover water stains on wooden floors or replace rotten or missing door stops or hardware around your home. For outdoor uses, use it to fill in cracks in decks and even repair rotted porch posts. Plus, if you’re conducting any DIY projects involving wood shaping or carpentry work woodworking putty can easily help create seamless joints where the pieces fit together perfectly without gaps.

Different Types of Putty and Which One Suits Your Project Best

Woodworking putty is a type of adhesive filler used in carpentry and joinery. It seals gaps between pieces of wood, allowing the piece to better withstand compression and tension stresses, while avoiding cracking and splitting. Putty can be divided into three categories: premixed, custom mixing, and epoxy putty.

Premixed putty comes in multiple colors to match the surrounding wood material. It is ideal for use with hardwoods like mahogany or oak because it does not require special upgrades for color matching. Premixed woodworking putty also dries quickly, making it well-suited for quick repairs on softwood projects. However, because premixed putties tend to lack strength when used on harder woods like balsa or plywood, they are best suited for use with softer woods such as pine or other common wood varieties.

Custom mixing putties are prepared by combining two components—the base element (a high viscosity liquid) and the hardener (a low viscosity liquid). Once combined, this type of putty strengthens over time while removing any air bubbles in the material between the pieces being joined together. Its strength makes it an appropriate choice for structural joints on material like plywood and particleboard; however, these putties have a limited color selection when compared to pre-mixed options. Also, additional tools may be required to help blend colors more closely together when working with this type of putty.

Epoxy putties are known as one of the strongest types of adhesives available for woodworking applications due to its flexibility which increases upon drying. These types of fillers are effective at filling large spaces and can sometimes be formed into desired shapes once dry. Epoxy putties come in both white and bronze colors that require no additional colors or extra shaping to match surrounding surfaces. Though stronger than premixed or custom mix options, this type does take the longest time to fully cure which must be taken into consideration when planning your project timeline accordingly..

Preparing the Surface Prior to Using Putty

When completing any woodworking project, the perfect finished product starts with meticulous planning and preparation. Before applying woodworking putty, it’s essential to properly prepare the surface area. This helps ensure that the putty adheres securely for a lasting solution. Start by assessing the surface for bumps, scratches and splinters which must be removed before applying putty. Sandpaper is an effective tool which can smooth out any imperfections or roughness in the wood. Sanding should take place perpendicular to any grain or texture in a slow back-and-forth motion, continuing until the entire surface area is even and smooth. Old paint may need to be scraped off in order to help the bonding process between the woodwork and putty. Be aware that if there’s any traces of dirt, grease or oil residue on this surface area, they will prevent a secure bond from forming and must be evaporated with rubbing alcohol or other suitable degreaser prior to applying woodworking putty.

Applying Woodworking Putty

1. Prepare the surface: Before applying the woodworking putty, it is important to make sure that you have prepared the surface properly by cleaning it thoroughly with a mild detergent or wood cleaner and then allowing it to dry completely.

2. Squeeze out the desired amount of putty: Next, take the desired amount of woodworking putty from the container and squeeze it onto your finger or onto a piece of scrap wood to give yourself something to work with.

3. Apply in thin layers: Once you have collected a suitable number of small dollops, begin gently pressing them into any cracks, holes or imperfections on your workpiece with your finger, being careful not to press too hard as this will push too much putty into any given area which can be difficult to correct. Aim for light and even coverage over several thin layers rather than trying to apply one thick layer since this will both reduce the chance of excessive shrinkage once dry and create a smoother finish overall.

4. Work over each area until filled: After you have applied several thin layers in many areas use either a plastic adjustable spatula or specifically designed flexible tool from your set (or something similar) to slowly work across each affected area until it appears consistent on all sides, then blend down further until there are no visible raised edges or dips which may occur during drying.

5. Sand down after completely dry: Allow to dry according to instructions (which depends on product), sometimes overnight, before sanding lightly with increasingly finer grades of sandpaper until a smooth finish is achieved then clean off with a damp cloth before painting if required – job done!

Tips and Techniques for Getting the Best Results

Woodworking putty is a useful item for repairing minor damage, filling voids and gaps, and resurfacing worn surfaces. To get the best results from using woodworking putty, it’s important to have the correct techniques and avoid common mistakes.

Selecting the Right Putty: Selecting the right type of woodworking putty for a particular job is very important. Most putties come in oil-based and water-based varieties. If a stainable finish is desired, an oil-based putty should be used. If there are areas that may need to be painted later on, a water-based putty should be used instead.

Preparing the Area: All dirt, dust, old paint, or any other debris must be removed from the area before applying woodworking putty. The surface should also be dry before application of the product as moisture can lead to swelling or sinking of the putty after drying. Sanding down a surface will help in providing an even texture for the application of new material.

Applying Evenly: A thin layer should be applied over the area on which you are working with a hard or soft rubbing pad or brush. Using temperamental amounts of pressure can cause unevenly distributed material and lumpy results when dried. Take care not to overwork it as this could also lead to undesirable finished product when dry.

Finishing Up: After allowing at least 12 hours for good drying time, lightly sand its surface for smooth finishing touches then prime and paint if necessary according to manufacturer’s instructions before using your newly repaired item! It’s always best to practice on scrap wood first until you are confident in your technique with working with woodworking putty before tackling larger projects!

Finishing the Putty

Finishing woodworking putty requires a few steps in order to achieve a professional looking finish. Firstly, the putty should be allowed to dry and cure according to the manufacturer’s instructions before sanding and refinishing. Upon drying, an abrasive paper of 220 grit or higher should be used with light strokes until all surface imperfections are evened-out. A fine grit buffing pad may also be used for smoothing out fine scratches and for adding a glossy finish to the putty. Finally, a clear coat of sealer is added over the entire surface and allowed to set, providing your furniture with a beautiful, durable finish.

Caring for the Putty in the Long Term

Woodworking putty is an excellent material for repairing structural damage, filling cracks and holes, and adding beautiful decorations to existing wood. But like any other material, its durability and longevity depend on proper care and maintenance. Here are a few tips for ensuring your woodworking putty stays in good condition over the long-term:

1. Clean the surface before applying the putty: Before applying woodworking putty, make sure you clean the surface you’re working on with a cloth dampened with warm water and detergent. This will help remove any dirt or debris that can affect the bond of the putty as well as creating an even surface for it to adhere properly.

2. Sand every level of cure thoroughly: Woodworking putty needs to be sanded throughly between each level of cure, starting with medium-grit sandpaper and then proceeding to finer grits until desired levels of smoothness are obtained. Doing this ensures your end product is solid and smooth rather than lumpy or brittle.

3. Apply additional layers judiciously: When repairing a large area or multiple cracks with woodworking putty, apply thin layers of it where needed instead of one thick layer. Multiple thin layers set better than one thick layer so that means it will also last longer once applied correctly.

4. Finish with protective polyurethane coatings: Once you’re done applying your woodworking putty, finish off by applying a protective coat of polyurethane or another sealant that’s suitable for wood surfaces. These coatings will help protect against UV damage from sunlight as well as against moisture that can weaken bonds in the putty itself over time


Using woodworking putty is a great way to revive and finish a woodworking project. Putty can be used to fill gaps, add texture, or create accents in your workpiece. It is important to understand when and how to use putty in order to maximize the outcomes of your woodworking projects.

When using putty, it is important to select the appropriate type for your needs since there are several specialised variations for different types of jobs. Some varieties harden quickly, while others require extended drying time before they can be sanded or drilled into. Understanding and following instructions for each type of product is essential.

The application process should also be carefully considered as putty should either be applied with a putty knife or even by hand in some cases. Applying too much pressure could affect the overall aesthetic look of the piece while not enough pressure may leave lumps that will be difficult to remove after drying. It’s also important to clean any excess residue off the surface right away using a damp cloth and then follow up with some fine-grit sandpaper if necessary.

Using putty can help restore an old piece of furniture, disguise imperfections, or simply highlight certain areas you wish to emphasize in a project. Understanding when and how much putty is needed as well as its type and application process is key in achieving maximum project outcomes when working with wood projects. As long as you take the proper precautions and heed instructions accompanying these products, success will certainly follow!
