Getting a wood splinter stuck in your finger or toe is no laughing matter.
The pain they cause is such that it is desirable to ensure that all wood objects are free of splinters.
However, without proper maintenance, you may find that wooden shelves, handles, and even doorknobs are at risk of splintering.
To fix this problem, you can turn to a product that is most associated with providing lubrication to metal objects.
Yes, I am talking about WD-40 which is one such product that can be used not only to fix the splintered wood but also to seal the wood so that it no longer splinters.
WD-40 will also expertly clean up your painted wood surfaces (like deck, floors, and furniture) as long as you quickly spray the product and wipe away the residue without allowing it to sit.
However, to make WD-40 work on wood, you will need to follow the right steps.
In this article we will cover:
How to Fix Wood Splinters with WD-40?
In addition to a can of WD-40, you will need to have some medium grit sandpaper and a clean, dry rag.
Once you have all three, you can start the process of making wood splinter-free.
Step 1: Sand
Use sandpaper to smooth out the wood.
The goal is to work from the top of the object to the bottom.
Pay particular attention to the areas that are most frequently touched.
You should sand away any rough patches or wood that is protruding.
Step 2: Spray Wd-40
Spray a generous amount of WD-40 onto the clean rage and rub it all over the wood.
This will not only clean up the wood but will provide protection over the long haul.
Keep in mind that sanding alone will smooth out the wood, but the splinters will quickly reform unless you add the WD-40.
The oil will protect the wood and keep it together, so it does not dry out and start to splinter again.
Plus, any metal objects inside the wood such as nails will be protected from rusting.
Step 3: Wipe the Surface
Wipe away the residue, and the wood is now prepared.
Every few months you should repeat the process to avoid the wood from splintering again.
And since WD-40 serves various different other purposes as well in your home and garage, it’s good to have a can or two of this sprayer solution in your store ready all the time.
How to Repair Splintered Wood without WD-40?
WD-40 is a multi-use lubricant that can be used to fix creaky and splintering wood.
But what if you do not have any WD-40 or perhaps the wood you are using does not work well with that product?
If so, there are ways you can repair the splintered wood without having to use WD-40.
For only a few splinters on the wood, you can easily break them off or cut them using a small saw or sharp knife.
If the wood has large splinters, you can follow these steps…
Step 1: Sand
Use 80-grit sandpaper on a palm sander to smooth out the wood.
This will reduce the weathered look of the wood, but it will get rid of the splinters.
Change to 120-grit sandpaper and smooth out the wood yet again.
If the wood is to become part of a floor or perhaps a table, then you will need the additional sanding to reduce the splinter count.
Step 2: Use wood filler
All nail holes and cracks should be filled with a wood filler.
Use a putty knife to add the filler compound and sand away the excess. Be sure the filler you use matches the color of the wood.
If that is not possible, then stain the wood after completion to even out the color scheme.
Step 3: Use polyurethane
Use a polyurethane finish for your barn boards or other types of wood.
If you do not have any polyurethane finish, then boiled linseed or tung oil can be used. In addition, shellac and lacquer are also good choices.
Be sure to follow the instructions from the manufacturer on how to use the finish.
Keep in mind that a heavy finish may not be necessary unless the boards are going to undergo a lot of use.
The finish will help keep the boards from splintering for a considerable time.
Will Painting or Staining Make a Splinter-Free Wood?
The answer is yes, it will make the wood splinter-free if you sand it first.
If you are thinking of re-coating your deck with a stain or paint, then you should follow the steps to make it splinter-free first and then add the outer coating.
To bring out the natural beauty of the wood, it is recommended that you use a semi-transparent stain.
Follow the instructions and apply the coat of stain quickly once the deck has been sanded.
However, if you are looking to better protect the wood from the UV rays of the sun along with the elements, then painting it is the answer.
You will want to use an acrylic-based finish as it is much thicker than standard paints.
Again, start by sanding the deck first to get rid of any splinters that might be present.
Next, use wood putty of a matching color to fill in any holes, divots, or cracks in the wood.
Then apply the finish or paint to the deck. Use a roller for the first coat and then a brush for the second.
This will provide for a smooth finish to the woodgrain. Be sure to allow up to three days for the paint to properly dry.
That will allow it to blend with the wood so you have a stunning deck to show off to your friends and family.
What causes wood to splinter?
Moisture is the real culprit that causes swelling and splintering in the wood.
The moisture can be due to spills, water leaks, or excess humidity in your house which is left uncontrolled for a long.
You can notice these splinters as rough edges on barn boards or roof boards that may have been weathered, cracked, have nails in them, and the like.
Splintered wood is not only unattractive but can be dangerous due to its sharpness.
And the worst part is if you leave it unrepaired – you are leaving the wood vulnerable to further splintering that can be hard to fix later.
Does wd40 damage wood finish?
WD-40 can safely be used to clean up and protect the wood from moisture and other corrosive elements.
Whether it’s bare or painted wood, you can spray some wd40 and wipe off the residue from the surface right away.
If you do it well without leaving the spray on the surface, wd40 will not affect the wood finish – but will clean the wood and keep it smooth and splinter-free for a long.
That’s the reason many woodworkers use wd40 for cleaning and fixing the splinters on hand tools that come with wooden handles.
How do you get WD-40 off wood surface?
Since WD 40 is a lubricant, it repels water which means you cannot clean it off by just using water.
To remove WD-40 from the wood surfaces, first wipe off the lubricant with a cloth or paper towel, as much as you can.
Then pour some dishwashing detergent liquid or shampoo on the wood surface.
Finally, wipe the surface using dampened sponge or foam in water to remove all the residue and stains.
Originally designed by the Rocket Chemical Company in 1953 as a degreaser and solvent for the aerospace industry, the use of WD-40 has quickly become widespread.
Not only to remove stains, grime, and grease from surfaces like metal and glass, this special blend of lubricants is also safe to use on wood, siding, and hardwood floors.
In fact, WD-40 is safe, effective, and inexpensive which makes it perfect to protect your wooden furniture around the home.
Just in case you find any splinters in your old furniture or want to fix the splintered wood boards use some WD-40.
It will most likely smoothen and fix the wood splintering problem very fast.
