Benefits Of Using Clear Finish On Your Outdoor Cedar Furniture
The following are the key benefits of using a clear finish on your outdoor cedar fixtures and furniture.
A clear varnish on the cedar furniture that you keep on the patio or for your cedar siding and deck will enhance the natural beauty of the wood by highlighting its warm glow. It will not hide the natural color of the wood, thereby showing it in all its glory.
Cedar furniture that you place outside will change its color if continuously exposed to the ultraviolet rays of the sun. These rays cause the natural color to become faded and thus, your cedar outdoor furniture will lose its luster if not given clear coats.
Protection Against Termites
The clear cedar finish is also used to protect your cedar furniture and fixture from mildew and termites. Once these set in, it becomes very difficult to restore the original condition of the wood as it starts to rot. Hence, clear finishes with mildewcides prevent the rotting of the wood.
The clear cedar finish on your outdoor furniture protects against water as you may accidentally spill water and there may be sudden showers. Water will get absorbed by the untreated wood and cause rot and damage.
Clear coatings also protect your cedar furniture and fixture from chemicals found in household cleaning agents and daily wear and tear.

If the clear cedar finish does not contain penetrating oils, chances are your furniture and fixtures outside your home will not get full protection. Hence, this product.
This natural wood colored finish contains an oil penetrating formula to nourish the cedar from within and keep it protected against mildew and rot. It also prevents discoloration from long exposure to the UV rays of the sun.
How the final finish of this product will look depends on the color and porosity of the wood. To ensure you have the desired tint, always test on a small part of the substrate before full application on the entire project.
Make sure the wood surface is dry and free from fibers, dirt, and mildew before application. Use a bristle brush or you can also sand the surface. The ideal moisture content should be less than 15%, otherwise, you need to expose the surface to dry weather for 3 to 5 days.
The application can be done after shaking and stirring the product thoroughly. Take care not to overapply the finish as that would lead to drying problems and a glossy result. Try to use a pure lambswool applicator for the optimum results.
If one container is not enough for your project, mix the contents of all the containers so that you have a uniform finish. Only one coat of the finish is recommended and apply it on small sections to prevent lap marks.
Depending on the temperature and humidity, the treated surface will need 24 to 48 hours to dry completely. While coverage on rough surfaces is 250 to 350 square feet per gallon, on smooth surfaces it is 400 to 600 square feet.Highlighted Features:

What To Look For Before Buying Clear Finish For Outdoor Cedar Wood?
Once you’ve decided to buy a clear cedar finish, then half the problem has been taken care of. However, there are a couple of factors to keep in mind before investing in a clear cedar varnish.
With temperature changes, the wood also expands or contracts. Besides temperature changes, sunlight and humidity also affect cedar. To keep these effects at bay, you should select a clear finish that contains special oils that enable the wood to expand or contract according to temperature changes.
The finish should also contain UV absorbers so that the fading and discoloring effects can be prevented.
Depending on how much usage the furniture and fixtures are likely to be subject to, choose a clear cedar polish. Some provide greater protection which is needed for furniture like tables and counters which usually come under heavy-duty usage as you are likely to put food and drinks on these places.
Tone Of The Finish
Some clear finishes are crystal clear while others have an amber hint that lends a warm and rich tone to the wood. With a light-colored cedar that’s either stained or unfinished, it’s better to choose a crystal clear finish.
How user-friendly the finish is will be determined by the ease of its application. Some can be applied with a cloth without the fear of leaving brush marks or making drips and they dry naturally. Others may dry very fast and need a soapy water solution or mineral spirits for cleaning up.
Tips to Take Care of Your Outdoor Cedar Furniture
By following the tips mentioned below, you can maintain your outdoor cedar furniture properly and extend their lifespan.
- Cleaning – Clean periodically with a solution made from water and mild detergent. Use a cloth for cleaning and a hose for rinsing. Using a pressure washer is not recommended as it may damage the wood.
- Mildew Removal – To remove stains or mildew, use a solution of water and bleach and apply to the affected area with a cloth. Allow to stay on for a bit but don’t let it dry there. Follow up with a rinse and allow it to dry naturally in a well-ventilated space.
- Sealing – Applying a sealant will keep the cedar protected from dirt and moisture that can cause rot. Also, it prevents the wood grain from rising and helps to keep its original warm tint.
- Staining – By using a clear or colored stain every two years, you can protect your cedar outdoor furniture from rotting. Paints are not advised as they lead to peeling by trapping moisture inside the wood grain.
- Dust Prevention - To prevent dust from settling on your cedar furniture, don’t use a finish that contains oil as that would attract dirt and grime.
- Off-Season Maintenance – Put away your patio cedar furniture in the garage during the winters and check for loose screws and bolts every season.
- Keeping Away From The Sun – It’s a good idea to put your furniture outside but choose a spot that doesn’t get the direct sunlight throughout the day. It will save your furniture from premature greying.
Frequently Asked Questions (FAQ)
1. What Happens If Cedar Outdoor Furniture is Not Given a Coating?
Answer: Untreated or uncoated cedar outdoor furniture will gradually lose its original color and assume a silver-grey tone. Though the tone looks great, the grain of the wood raises when left untreated, and hence, the furniture surface becomes uneven. Moreover, some strong stains begin to show.
2. What Type of Finishes are Not Recommended for Cedar?
Answer: Varnish, shellac, urethane, and lacquer are the types of finishes not recommended for outdoor cedar fixtures and furniture. That’s because they are transparent and will not be able to block the discoloring effects from the ultraviolet rays from the sun.
No matter the number of coatings you may apply, these finishes will eventually lead to cracking and peeling of the wood.
3. What Are the Factors That Affect the Application of Clear Cedar Finish?
Answer: The application of the clear cedar finish will have a direct impact on the result and performance of the finish. The surface should be clean and dry before application. The application can be done by using a spray, a brush, a roller, or a cloth. Hence, this will impact the result.
Moreover, the amount of the finish used and its quality along with the weather during the application will have a long-term effect.
4. What’s the Difference Between Latex and Oil-Based Finishes?
Answer: Oil-based finishes penetrate the wood and keep it nurtured and protected from within. These finishes last longer and keep the cedar protected for a long time. However, the application can be somewhat messy.
Latex finishes are of a thin consistency and hence, easy to apply. However, they do not penetrate the wood and therefore, do not provide a long-lasting effect.
5. What Are the Positives and Negatives of Clear Cedar Finishes?
Answer: Clear cedar finishes do not change the original appearance or color of the wood. Also, they come with anti-fungal ingredients to discourage the growth of mildew. Another advantage is that it requires very little surface preparation before application.
However, the downside is that they don’t give protection against the UV rays that causes the wood color to fade away. That’s why you need frequent applications of a clear cedar finish for outdoor furniture.
As you have figured out by now, purchasing cedar furniture for outdoors is not enough as you need to ensure they serve your purpose for a long time by taking care of them properly.
Putting a finish on your outdoor cedar fixtures and furniture is the main part of overall maintenance. No matter how often you dust and clean them, nothing will retain their natural beauty than putting a coat of a clear cedar finish.
A clear finish will penetrate the wood and keep it strong from within and maintain its natural goods on the outside. Moreover, the finish will discourage mildew growth and hence, keep rotting of the wood at arm’s length.
We hope this article will help you select the best clear cedar finish for outdoors so that you can enjoy the summer on your favorite furniture without getting concerned about its durability.
