Extend The Life of The Furniture With The Best Wood Sealer

Wood sealer is a water- or oil-based liquid used to protect wood from all kinds of damage: water, UV radiation, mold, and the list goes on. You simply brush or spray it on, wait anywhere from a few hours to a few days, and voila! The wood will take on a slightly shinier appearance and be protected from just about anything life throws at it.

Are you ready to start shopping around for wood sealer? We’ll help you figure out which products are worth your time and money, and give you a few pointers on what to look for. Let’s go.

What to Look for in a Wood Sealer

Not all wood sealers are created equal.

At the bare minimum, a good wood sealer should protect the wood from water and moisture without tarnishing its appearance. But you should also consider factors such as the sealer’s base ingredient, how safe or eco-friendly it is to use, and if it has any additional protective capabilities.

To give you a head start in your shopping adventure, here’s a quick breakdown of what to look for in a wood sealer.

Water-Based vs. Oil-Based

You can find wood sealers in water-based and oil-based formats. Both types of sealers have their advantages and disadvantages.



  • Maintains a clear appearance on the wood
  • Dries faster to allow for multiple recoats per day
  • Has no noticeable smell


  • More expensive
  • Can lend the wood a dull appearance



  • Less expensive
  • Thicker composition for fewer recoats
  • Can lend more vibrant color to the wood


  • Has a strong smell
  • Can cause yellowing of wood over time
  • Takes longer to dry

The type of sealer you opt for should depend on your budget, your preferences, and the project you’re working on.


The point of wood sealer is to protect the wood. But there are many types of wood sealers available on the market today, each one with its own protective capabilities and intended use. There are a few things you should look for in a wood sealer, though, especially if the wood you apply it to will be kept outdoors.

  • Most sealers offer waterproofing, arguably the most important of wood protections. Waterproofing keeps the wood from rotting when exposed to moisture by causing the water to bead rather than seep into the wood.
  • UV Protection. This is especially important if you live in an area known for high temperatures and plenty of sunshine. UV protection will keep the wood protected from the sun’s UV radiation, which could otherwise cause issues such as fading and splitting.
  • Dark Stain Prevention. Over time, substances such as fungi or mildew can cause ugly dark spots to appear on the wood. Products that feature dark stain prevention will keep the wood safe from these substances to ensure a great appearance in the long run.

If you’re working on an outdoor project, we highly recommend you opt for wood sealers that feature UV protection and dark stain prevention. These may cost a little more, but they’ll keep the wood looking nice for a lot longer!


If the environment—or your health—is your number-one concern, then opt for a wood sealer that’s eco-friendly.

Water-based products tend to go easiest on the environment, while oil- or polyurethan-based sealers take more of a toll. Also, avoid sealers that contain VOCs (volatile organic compounds) when possible, as VOCs are known to be toxic to the environment.


Depending on your woodworking project, one type of application method may be more convenient for you than another. Two popular application methods are:

  • This is the most commonly used application method. Wood sealers meant to be applied by brush usually come in a large can (similar to a paint can).
  • Aerosol can be a better method for certain projects. Wood sealers meant to be applied by aerosol will usually come in a special aerosol can. You may find that aerosol application is a tad easier than brush application, and the aerosol cans tend to be easier to transport.
  • Power spraying. This method is generally ideal for larger-scale projects that require a solid wood sealer coating.

Once you’ve spent the time and money applying wood sealer to your project, you’ll want it to last! Most wood sealers can last anywhere from 1 to 3 years before reapplication is needed.

Color & Aesthetics

Finally, you can purchase wood sealers that double as a stain. If this appeals to you, then explore your options and look for the stain or finish color that will best suit your project and preferences. Satin and semi-glossy stains are fairly popular as they offer a subtle, attractive finish.

On the same note, remember that oil-based sealers tend to make the wood appear a bit darker while water-based sealers have less of an impact on the appearance.
