Advantages of Using Clear Finish On Outdoor Cedar Furniture
A clear finish is an ideal choice for exterior cedar furniture. Why is it so? Let’s see why the clear finish is the best stain for exterior wood.
Enhances the beauty of natural cedar
Cedar wood is beautiful even without being stained. It has natural oils that allow it to survive the harshness of being exposed to elements such as snow, rain, UV rays, mold, mildew, etc.
However, it can only fight for so long unaided. With time the elements wear out, and cedarwood starts to fade and rot.
When you use clear stains, you bring out the natural beauty of cedar and fortify its defense against the elements simultaneously.
So, if you value your expensive wood, it is only fair that you give it a fresh lick of transparent stain and keep applying a maintenance coat as needed.
Prolongs the life of wood
Outdoor cedar remains outside regardless of weather conditions. It is prone to insects, mold, and mildew attacks which causes the wood to decay.
Clear stains contain mildewcide and penetrating oils that protect the wood from insects, UV rays, and water damage, therefore, prolonging the lifespan of cedar.
Staining a cedar wood surface also makes the areas much easy to clean. Every coin has two sides, and everything on this planet is.
The only disadvantage of clear stains is that they do not hold up as long as a solid.
How to Finish Cedar Wood for Outdoors
You finish exterior cedar wood the same way you would finish interior wood. The only difference is to know the type of finish you are using is a water-based stain or oil-based stain.
You do not need to be too cautious with water-based stains because most are low VOCs and won’t emit pungent odors, and are safe for pets, kids, and the environment.
However, you need to be careful with an oil-based stain. If you use an oil-based stain, always wear protective equipment and work in well-ventilated spaces.
The most important question to ask when treating cedar is, “How much of the actual wood grain do you need to conceal ?” Do you prefer the natural, weathered appearance of cedar? Or do you like a uniform but unnatural appearance?
A semi-transparent stain lets the wood grain shine through and gives the wood the much-needed protection. Solid color stains cover the color of cedar but let some grain shine through.
Here’s a step-by-step process for finishing cedar wood for exterior use.
Requirements
- Your preferred Wood Finish
- Cleaners/Stain Removers
- Sandpaper
- Brush/Roller/Pad
- Procedure
Step 1: Sand the wood
Sand the surface and clean the wood to remove sanding dust, debris, and dirt. Avoid using a pressure washer as it may damage the wood. Wipe the wood with a clean cloth or sponge.
Step 2: Remove the previous coating
If the wood was previously stained or it has some scratches grab fine-grit sandpaper and sand it down. Use a stain remover to remove paint finishes and stains.
step 3: Apply the finish
Apply your favorite stain with a sponge, clean rag, pad, or roller, depending on the surface you are working on. Hold it at 45 degrees and run the soft bristles across the surface uniformly and gently if you are using a brush.
Step 4: Allow the finish to dry
Let the finish dry according to the time the manufacturer stipulates and wipe away the excess finish. Sand the wood with fine-grit sandpaper before applying a second coat. Reapply the coats as needed and let the wood cure.

FAQs
Can you clear coat cedar?
Yes, cedar can be clear-coated, showcasing its natural beauty while providing protection. Clear coats work best indoors but can be used outdoors; however, they’ll break down faster than stains or paints due to exposure to elements like UV rays, rain, and mold.
How do you seal outdoor cedarwood?
Start by cleaning and sanding the surface. Apply a high-quality wood sealer or penetrating stain specifically designed for outdoor use, such as a UV-resistant, water-repellent finish. Brush or spray on evenly, allowing it to dry fully. Reapply as recommended to maintain cedar’s natural beauty and weather resistance.
Should cedar be sealed for outdoor use?
Cedar is a dependable option for exterior and interior building projects because it is durable. It has natural properties such as natural oils that enable it to resist insects and rot, and decay. So, staining it is optional. It is advisable to seal it to fortify its defense against the elements. However, leave it unsealed if you need to enjoy the sweet aroma of cedar variants such as Incense-cedar and Western Red Cedar.
What is the best clear stain for cedar?
Linseed oil is the recommended finish for exterior clear cedar. It is the primary component of certain oil finishes that dry clear. Other clear water-based finishes exist, but they will not last as long as a Linseed oil-based stain.
Conclusion
We highly recommend finishing exterior cedar with clear stains because they allow the natural beauty of wood and color to show through.
A clear cedar finish also strengthens cedar’s natural defense against mold, mildew, moisture, and UV rays. The Optimal Clear Cedar Coatings for Outdoor Use should last for a while before necessitating maintenance coat application.
