If you require more than one can, combine the contents of all containers to get a uniform finish. Apply the paint with a sprayer, brush, roller, or painting pad.

Apply thin coats instead of one thick coat for maximum absorption. If you apply many thick coats, the paint might crack, rendering all your efforts fruitless. Also, it will delay the dry time, making your project take longer than expected.

Wipe away any excess finish before it completely dries, or distribute it to the untreated wood parts. We consider it one of the best clear stains for natural cedar because just one coat is enough to give you professional results.

Nonetheless, you can do a second coat if you need a darker tone. Patience pays all the time. Wait for two hours for the first coat to dry, and give the second coat four hours to dry before recoating if you need to.

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.

Using Clear Finish On Outdoor Cedar Furniture

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

How to finish cedar wood outdoor

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.


  • 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

Removing old paint coating from cedar

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.

Can you clear coat cedar?

Yes, you can clear coat cedar, but you need to know a few basics beforehand. Clear coats work exceptionally indoors because they are not exposed to elements responsible for wood degradation, such as rain, algae, mold, insects, snow, and intense UV rays.

They’ll still offer considerable protection against these elements even when used outdoors. Still, they will break down faster than solid stains or paint finishes. Clear coats let the color and the wood grain shine through, therefore amplifying cedar’s natural beauty but wear out with time.

On the other hand, solid transparent stains cover the color of cedar but allow the grain to shine through and are more durable than clear stains. A paint will obscure the grain and the color of wood but painted surfaces last longer. You choose what to go with based on your needs and styles.

How do you seal outdoor cedarwood?

You seal Outdoor cedar as you would interior cedar. Just pay attention to the type of finish you are using and follow relevant safety instructions. Sealing outdoor cedar is straightforward. Sand the surface and wash it to remove dirt and debris. Apply the first coat and let it dry. Lightly sand between the coats with fine-grit sandpaper. Let the final coat cure before using the project.

Can cedar be clear coated?

Yes. You can coat cedar just like other dense wood with clear stains, paints, or shellac or use a solid stain. You need to know the pros and cons of each coating and make an informed decision based on your preferences and needs.

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.


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.
