Patch It Right: How to Fill a 2-Inch Hole in Wood with Precision

Holes in wood can occur for many reasons – from knots falling out when wood dries, to damage from screws or nails. While small holes may not affect wood structurally, larger holes need to be filled to restore the wood’s appearance and integrity. Filling a 2 inch hole in wood can be done in several ways using various materials. This article will overview the most common methods for filling holes in wood.


Filling holes in wood is an essential skill for carpenters, woodworkers, and DIYers. The goal is to completely fill the hole with a material that blends into the surrounding wood. Holes should be filled to create a smooth, uniform surface for finishing the wood.

The best method for filling a hole depends on the size and depth of the hole, type of wood, final use of the wood, and tools/materials available. In general, shallow holes under 1 inch can be filled with wood putty. For holes 1 inch or larger, methods like using dowels, wood plugs, or epoxy are better options.

This article will focus on several methods for filling a 2 inch diameter hole in a wood surface. The pros and cons of each method will be discussed to help you choose the right option for your project. With the right preparation and technique, you can fill holes in wood seamlessly.

Method 1: Sawdust and Wood Glue

One easy option for filling small to medium sized holes is using sawdust from the project wood combined with wood glue. Here is how to fill a 2 inch hole using this method:

What You Need

  • Sawdust from sanding the project wood
  • Wood glue
  • Plastic spreader or putty knife
  • Sandpaper


  1. Sand the edges of the hole to create a clean, rough surface for the filler to adhere to.
  2. Mix sawdust with enough wood glue to form a thick paste that packs firmly into the hole. The ratio is approximately 2 parts sawdust to 1 part wood glue.
  3. Force the sawdust mixture into the hole using a putty knife or plastic spreader, overfilling slightly.
  4. Allow the filler to dry completely, then sand flush with the surrounding wood. Start with 80 grit sandpaper, then finish with 120 and 220 grit.


  • Makes use of sawdust so no waste
  • Natural color match to wood
  • Durable bond and stainable


  • Can shrink slightly when dry
  • Not ideal for large/deep holes
  • Long clamping time for glue to cure

When using sawdust and wood glue, make sure the filler is packed tightly into the hole to prevent shrinking. Clamping a block over the filler while drying helps keep it flush with the surface. This method works well for small holes in softer woods like pine but may lack the strength needed for harder woods.

Method 2: Wood Filler

Wood filler, also called plastic wood, is a commercial product designed to fill holes and imperfections in wood. It is available premixed or as a two-part filler that must be mixed. Here’s how to use wood filler on a 2 inch hole:

What You Need

  • Wood filler, preferably 2-part epoxy filler
  • Putty knife
  • Sandpaper


  1. Sand and clean out the hole to remove any dust or debris.
  2. Force the filler deeply into the hole, overfilling slightly. Strike off excess filler flush with surface using the putty knife.
  3. Allow filler to fully cure per manufacturer directions, usually 24-48 hours.
  4. Sand smooth with 120 or 220 grit sandpaper once cured.


  • Formulated to fill wood holes with good color match
  • Cures quickly and sands easily
  • Minimal shrinkage


  • Premixed filler has limited shelf life
  • Can show visible seam if not properly packed into hole
  • Not as strong as wood-based fillers

Two-part epoxy wood fillers provide the best filling for large holes. Make sure to push the filler into the hole rather than just covering the surface. Sanding sealer can help blend wood grain differences after filling. I like to use wood filler for small nail holes and imperfections in trim work where you need a quick filler that blends well with painted surfaces.

Method 3: Wood Dowel

For round holes 2 inches or larger, a wood dowel is an excellent filler option. The steps are:

What You Need

  • Wood dowel with diameter slightly larger than the hole
  • Wood glue
  • Saw
  • Sandpaper


  1. Sand the edges of the hole. Cut a dowel to a length slightly longer than the depth of the hole.
  2. Apply wood glue around the inside of the hole. Insert the dowel into the hole, tapping lightly with a hammer if needed to fully seat it.
  3. Allow the glue to dry fully then use a saw to trim the dowel flush with the surface.
  4. Sand until the dowel is flush and smooth with the surrounding wood.


  • Very strong repair
  • Natural look when stained/finished
  • Does not shrink


  • Visible seam if wood colors don’t match exactly
  • Requires close fit of dowel to hole

When using a wood dowel, choose a hardwood species that closely matches the color of the project wood. Apply glue to both the dowel and hole to create a permanent bond. Cutting dowels allows you to fill a hole at any angle, unlike a pre-cut plug. Wood dowels are my go-to way to repair round damaged areas or replace broken spindles on furniture.

Method 4: Wood Plug

For smaller round holes, a precisely fitted wood plug makes for a professional looking repair.

What You Need

  • Wood plug slightly larger than the hole
  • Wood glue
  • Hand chisel
  • Sandpaper


  1. Drill a hole into scrap wood that’s slightly oversized for the existing hole. Slice out a plug from this hole.
  2. Apply glue into the hole. Place the wood plug into the hole and tap it down flush with a hammer if needed.
  3. Allow the glue to fully cure then use a sharp chisel to pare the plug perfectly flush.
  4. Finish by sanding until smooth.


  • Excellent strength and end grain match
  • Plug can be precisely flush if chiseled
  • Stains/finishes well to blend with surrounding wood


  • Requires extra steps to create plug
  • Visible seam if wood colors vary

With practice, you can create a nearly invisible repair using a wood plug. Choose your plug wood carefully to match the existing wood color and grain patterns. I like using plugs to repair small defects and knots in table tops or other visible surfaces. The grain match helps maintain a seamless look.

Method 5: Epoxy

For deep holes or where very strong repairs are needed, epoxy makes an excellent hole filler.

What You Need

  • 2-part epoxy resin and hardener
  • Mixing sticks/cup
  • Sandpaper


  1. Make sure the hole has clean, rough sides to give the epoxy something to grip.
  2. Mix a small batch of epoxy according to package directions. Pour the epoxy slowly into the hole, filling past the surface.
  3. Allow the epoxy to fully harden, which can take 24 hours. Sand flush with the surrounding wood.


  • Extremely strong and durable repair
  • Does not shrink
  • Allows depth repairs not possible with wood filler


  • Difficult to tint epoxy to match wood exactly
  • Takes experience working with epoxy
  • Can be more expensive than wood filler

When working with epoxy, make sure to follow all safety precautions. The resin and hardener can irritate skin and eyes. Filling large holes may require multiple thin epoxy pours. I’ve used epoxy to rebuild corners of furniture damaged by water rot and it provides an incredibly tough, long-lasting repair in those situations.

Method 6: Corkscrew or Screwdriver

A simple way to fill very small holes under 1/2 inch is by twisting a corkscrew or screwdriver into the hole to pull up wood fibers. The steps are:

What You Need

  • Corkscrew or screwdriver
  • Sandpaper


  1. Twist the tip of the corkscrew or screwdriver into the hole. Move in a circular motion to bring up wood fibers.
  2. Keep twisting until the hole is filled with lifted wood fibers. Remove the tool.
  3. Once dry, sand the filler and surrounding area to blend flush.


  • Quick and easy method
  • No filler products needed


  • Only works for tiny holes
  • Results depend on wood species

This corkscrew method works best on soft woods like pine, where the fibers lift easily. It is only suitable for small nail or knot holes no more than 1/2 inch in size. I keep a small corkscrew in my workshop just for quickly filling the tiny defects that occur when working with natural wood products.

Method 7: Patching Compound or Spackle

For small holes in soft woods, lightweight patching compounds can be used to fill the hole flush.

What You Need

  • Patching compound or spackle
  • Putty knife
  • Sandpaper


  1. Make sure the hole is free of dust and debris. Apply a small amount of patching compound with a putty knife.
  2. Strike off any excess and allow compound to dry per package directions.
  3. Once dry, sand flush with wood surface.


  • Very easy to apply and sand
  • Fast drying time


  • Only suitable for small, shallow holes
  • Not as durable as wood fillers
  • May shrink if applied too thick

Patching compounds dry very fast but lack strength compared to wood filler. Only apply to small holes where minimal filling is needed. I keep spackle on hand for quickly patching holes left from removing nails or hardware in wood trim and molding. It sands smooth and blends well with painted surfaces.

Method 8: Creative Solutions

For small holes, there are also some creative solutions that use items like:

  • Coins or medallions
  • Buttons
  • Marbles or beads
  • Small shells
  • Dried beans or pasta
  • Wine corks


  1. Make sure the object fits fully into the hole depth. Glue into place if needed.
  2. Allow any glue to dry then sand object flush with the surrounding wood.


  • Adds interesting details to wood projects
  • Makes use of items found around the house


  • Only suitable for shallow, small holes
  • Items may eventually fall out if not glued

When using unique objects to fill holes, choose items that coordinate with the design and function of the wood project. Make sure surface is smooth and objects sit firmly in holes before finishing the wood. My wife likes to fill small knot holes in serving trays with tiny seashells from our vacations. It adds personality and a neat conversation piece when guests notice the shells.

Advanced Hole Filling Techniques

For more advanced hole repairs, there are several additional methods a skilled woodworker can use:

Dutchman Repair

A dutchman repair uses a precisely fitted wood patch, known as a dutchman, to fill a damaged area of wood. This is done by:

  1. Cutting out the damaged section into a rectangular hole.
  2. Cutting a patch from matching scrap wood so it fits snugly into the hole.
  3. Gluing the patch into the hole so wood grain is aligned.
  4. Sanding and refinishing the repair smoothly.

When done properly, a dutchman repair is nearly invisible. The tight fit and wood grain pattern disguise the hole. This is an advanced method but useful for repairing splits, gouges, and damaged sections in high-end furniture and woodwork.

Wood Veneer Filler

Thin sheets of wood veneer can be used to fill holes and cracks in veneered surfaces. This involves:

  1. Cutting a piece of veneer slightly larger than the hole.
  2. Using veneer glue to affix the patch into the hole, aligning wood grain direction.
  3. Using a veneer hammer to tap the patch flush with surface.
  4. Sanding and refinishing to blend repair.

Matching the existing veneer wood, grain, and thickness is key for invisible repairs. This technique is great for repairing damaged veneer on plywood cabinets or furniture.

Drilling and Plugging

For larger holes and defects, the area can be drilled out and replaced with a plug:

  1. Use a drill to enlarge the hole into a clean, uniform round shape.
  2. Cut a wood plug to fit snugly into the drilled hole.
  3. Glue and insert wooden plug using methods described earlier.
  4. Sand and refinish plug.

This allows you to get a tight fitting plug while removing damaged or uneven wood around the hole. Useful for repairing knot holes, burns, and other larger defects.

Filling Holes in Wood Trim and Molding

Trim pieces like baseboard, crown molding, and door/window casings often get damaged over time. Fill small nail holes and defects in trim with these tips:

  • For narrow holes under 1/4″, use wood putty without sanding by pressing it into holes with fingertip. Wipe excess with damp cloth.
  • For larger holes, use plastic wood filler and allow to fully harden before sanding smooth.
  • Look for putty that matches your trim color – white for painted trim, natural wood tone for stain grade trim.
  • Carpenters wax filler sticks can quickly fill imperfections in stained wood trim.
  • Spackle works well for quick hole filling in painted trim but not for stain grade wood.
  • Take trim boards off work to fill holes, dents, and defects before reinstalling for a flawless look.
  • Fill holes flush to surface – avoid overfilling which requires more sanding and risks damaging wood profiles.

With careful hole filling, you can give wood trim and moldings a seamless, quality appearance. Take time to choose right filler and color for the job.

Filling Large Holes in Wood Doors

Wood doors often get damaged from impacts, pet chewing, or drilling out old hardware. For noticeable holes up to 3 inches in size, use these filling techniques:

  • Clean out hole then pack tightly with wood glue and sawdust to provide structure. Let fully dry.
  • Fill over sawdust base with wood filler, applying in thin layers. Allow to harden between coats.
  • For extra strength, cut a backer piece of wood like luan plywood to fit hole. Glue in place before filling.
  • Sand door fill smooth when fully cured then repaint or refinish door to match existing look.
  • Consider replacing door rather than patching if hole is over 4 inches or severely damages door structure.

Proper surface prep and building up fills in layers will create the best long term hole repair in wood doors. Take time for fillers to fully cure before sanding or refinishing.

Tips for Drilling Holes in Wood

When drilling holes in wood for hardware, shelving supports, or other uses:

  • Use sharp drill bits suitable for the hole size and wood hardness. Carbide tipped bits cut cleanly.
  • Clamp wood piece securely and drill perpendicular to surface. Apply firm pressure.
  • Drill slowly, especially when hole exit point could chip out wood fibers.
  • Lubricate large twist bits with wax stick for smoother cutting.
  • For angled holes, use a drill press with tilt table or angled jig.
  • Place scrap wood beneath workpiece to prevent tear out when drill exits.
  • Clean holes with round file or sandpaper wrap to remove fraying or splinters.

With care and these tips, you can drill clean, splinter-free holes in wood for your projects. Take time to prep workpiece and use quality bits.

Filling Screw and Nail Holes

When screwing and nailing wood, the fastener holes need filling for a smooth finish:

  • For small nail holes under 1/8″, use colored wax wood fillers for quick hole filling without sanding. Just fill and wipe clean. Match filler color to wood.
  • Larger nail holes can be filled with plastic wood filler, wiping off excess when still wet for a flush finish.
  • Dimpling or countersinking screw holes allows filler to be quickly applied without sanding.
  • Damaged screw holes may need glue and toothpicks or golf tees to fill deeply before using filler.
  • Use wood putty for filling fastener holes in painted wood trim. It sands easily and takes primer and paint well.
  • Let fastener hole fills fully cure before sanding, staining, or painting over repairs.

Taking steps to properly fill in screw and nail holes will lead to an attractive finished wood project free of defects and blemishes.

Preventing Holes When Working with Wood

The best way to handle holes is to avoid creating them in the first place when woodworking:

  • Use a punch or awl when starting screws and nails to prevent wood splits.
  • Drill pilot holes for all screws and nails to minimize splitting force.
  • Place scrap wood beneath work when drilling through pieces to prevent tear out.
  • Work slowly and carefully when sanding to prevent dipping into wood surface.
  • Ensure wood is fully supported when sawing, routing, or chiseling to prevent gouges.
  • Apply painter’s tape around drill locations on finished wood to prevent splintering.
  • Use a backer board when drilling holes on the edge of a workpiece.


In conclusion, filling holes in wood is a fundamental skill for carpenters, woodworkers, and DIYers. These holes, caused by various factors, necessitate restoration for both aesthetics and structural integrity. We’ve explored multiple methods for addressing 2-inch holes, each with its own advantages and drawbacks. From sawdust and wood glue for a natural finish to commercial wood fillers for quick solutions, wood dowels and plugs for strength, epoxy for durability, and even simple methods like corkscrews or screwdrivers for tiny holes. The choice depends on factors like hole size, wood type, and project goals. With the right technique and materials, you can seamlessly fill wood holes, but it’s vital to consider the specific requirements of your project, as each method offers a unique set of benefits and limitations. Practice and experience will refine your results, ensuring a professional and polished final outcome.
