Step 3: Apply The Filler To The Wood Surface 

Start by applying wood filler to the area where repair is needed. As the filler dries, it will slowly shrink, so you should add a little bit of the filler as needed. 

Step 4: Use A Putty Knife To Smooth The Filler

After using the appropriate filler, use a clean section of a putty knife to smooth over the filled area.

If you have any residue left on your hands, clean it off using a mineral spirit if you're using a petroleum-based filler. If you are using a water-based wood filler, use water.

Step 5: Let The Wood Filler Dry

If you have already filled out the damaged areas, wait until the wood filler dries. Allow the filler to solidify for at least 30 minutes; an entire hour is preferable. It may be challenging to hand sand true wood fillers after they have dried to a hard state. 

For deep, large areas, allow the filler to dry for more than an hour, depending on how much filler you put into the wood. 

Step 6: Sand The Filled Area

When the wood filler is dried enough, finish by hand-sanding the filled area using sandpaper while moving the paper down the grain of the wood. In addition to helping the filler absorb the stain, it will create tiny scratches in the filler that resemble the pattern of the adjacent wood.

Step 7: Apply Some Finish To Retouch

Start retouching the woodwork with some finish applicable to your wood project. After thoroughly cleaning the area, the patch or filled crack can now be stained and given a protective finish.

Expect the filler to be somewhat noticeable, but don't expect it to be completely undetectable. Staining the product will assist in balancing the color variances between the filler and the adjacent wood.

Wood Maintenance

If you plan to use wood filler, you should keep your wood in good condition. Maintaining your wood will help you use less filler.

  • Use a primer with oil in it. As a result, the wood will continue to be moisture-resistant and won't fracture where the filler is being placed.
  • Use various cleaning products, not just one, to clean your home's baseboards, windowsills, and doors. You should clean all of them with products that won't cause their finish or color to fade and or leave any residue.
  • Use wax on doors, window frames, and other woodwork as necessary during the cold season because these areas more likely to get moist due to the freezing conditions. 
  • Use a clean cloth or any fabric material to wipe off dirt and dust on the wood. 
  • Only use low-pressure cleaning products to prevent the wood fiber from opening up and causing minor damage.

The two types of wood fillers are water-based wood fillers and petroleum-based wood fillers. Both function independently depending on which works for your wood. 

Water-Based Wood Filler

Water-based putties or fillers are easy to recognize since water is recommended as a tool cleaner in the instructions.

Petroleum-Based Wood Filler

You can easily recognize petroleum-based products because they require acetone, mineral spirits, or some other chemical solvent in the instructions. 

These kinds of wood fillers not only conceal and close up holes in the wood but also bind the pieces of the wood together, reducing the chance that cracks would form throughout the time in the holes and open joints.

Difference Between Wood Filler And Wood Putty

If you're still unfamiliar with the usage and purpose of wood putty and wood filler, they have the same goal: to fill gaps in wood. However, they are different when it comes to their usage and their components.

Generally, most wood fillers are water-based and composed of the wood fiber. Most wood putties contain plastic that functions like epoxy.

Wood Filler

Wood filler is a material that can be sanded. It is coated in a mixture of hardening resin that can penetrate and link with wood fibers. It consists of a mixture of wood dust with lacquer, varnish, or glue. 

Wood Putty

Wood putty is a combination of oil-based solutions and plastic material. Wood putty is more flexible and denser than wood filler. It also requires the use of a putty knife. 

Most woodworkers also use wood putty for quick fixes and to hide little flaws such as minor joint misalignments, little marks, and nail holes.

Can You Put Bondo Fillers On Painted Surfaces?

Bondo ultimate fillers can be layered directly over painted surfaces that have been primed and allowed to cure. Applying fillers to factory paint that has been cleaned and sanded will work. Days after application, the filler can still be easy to sand. 

What Kind Of Primer Should I Use On Wood?

Latex or oil-based primer is appropriate for raw wood, depending on the paint you plan to use. The oil-based primer is required for wood like cedar or redwood since it penetrates deeper into the wood and helps to avoid yellowish or brownish stains.

Before painting, unfinished wood should be primed. The wood grain can be filled in and smoothed out with the help of primer with high-solid content.

Unfinished wood tends to soak in paint as raw drywall, but primer helps seal the surface to stop this from happening.

Summing Up

Wood filler provides a quick, temporary remedy for minor imperfections like cracks and dents to the wood. If you want to apply it on corners, you should mix the wood filler, sand down any rough areas, and apply the mixture to the portions that need repair.

You'll need to use a putty knife to smooth out the filler before letting it dry and sanding it. After that, all you need to do is apply some finish to retouch it.
