Why Stain Your Exterior Cedar Siding? + Pros and Cons

There are several advantages to using an exterior stain for cedar.  For starters, it will maintain the wood in pristine condition for a long time.

The siding will deteriorate much faster without any kind of protection.

If you use a good stain, your cedar siding will appear better. You may dye it any color you like, which will hold up well against the sun’s rays. These stains don’t persist forever but can be easily touched up.

Staining is relatively easy to apply. Most stains require neither priming nor even extensive sanding before application. They can be applied quickly using a sprayer or brush. Staining your cedar siding is a no-brainer, in conclusion.



Exterior Stains for Cedar Siding Buyer’s Guide

Water-Based or Oil-Based?

It’s essential to consider whether you need an oil- or water-based stain product before purchasing.

The color of water-based stains is richer than oil- or latex-based stains. It’s nonflammable and doesn’t give out any unpleasant odors. You can use merely water and soap to clean most water-based goods.

mixing Defy Extreme Wood Stain

An oil-based stain is more weather-resistant because of the oils inside them.

They dry slow and hold their sheen, so you won’t have to worry about maintenance for long. Likewise, oil-based stains last much longer than their water-based counterparts.


Solid Color Stain

To achieve a different shade, apply a solid stain designed for cedar siding. Due to the stain, the wood is unrecognizable. It’s a more robust defense against staining than anything else out there.

But even the best exterior solid stain can be hard to work with due to’s thickness and inherent difficulty.

Regarding how much it soaks into the wood, an exterior solid stain is between paint and a semi-transparent or solid stain. Solid stains give the wood a uniform coating of color without fully covering up the natural wood grain.


A semi-transparent stain is a wiser option if you’d like to paint your home’s exterior differently while still revealing the wood below.

When protecting against the elements, this stain is far superior to the transparent and solid varieties.


It is essential to verify what comes with a transparent stain, as some brands provide tinted stain hues in addition to the clear variety.

Nonetheless, the original color and elegance of its wood grain are highlighted in both, making them suitable for individuals who desire subtle adjustments to the overall tone.

Area Coverage

It would be a shame to get the sidings about 90% stained before realizing you’re out of stain. Staining might only sometimes dry uniformly if you wait too long, leading to less-than-ideal results.

While specifics vary per stain, you should expect one gallon to treat between 200 and 300 square feet. Before staining the siding, getting a ballpark estimate of the space, it will cover is a good idea.

Consider how many layers will be required as well. Using simply one coat of stain for many projects may be more cost-effective. If you want to make a big difference in the hue, you may require an additional coat of stain.

VOC Content

Low-VOC content stains are preferable since they provide the same degree of performance without damaging or staining your surface.

When using a stain for cedar siding with low volatile organic compound (VOC) content, you won’t need to wear protective gear like gloves and a face mask, which saves you money and protects you from unnecessary chemical exposure.


Environmental factors, including temperature and humidity, significantly affect the rate at which a stain dries. Even the best exterior stain can take three times as long to dry if it’s damp or chilly outside.

The stain or paint will still be wet until the relative humidity or temperature rises.

But if the temperature rises too much, the stain may dry too rapidly, possibly leaving lap lines or uneven penetration behind.


Stain is used primarily to prevent damage to the underlying wood. Depending on several factors, your level of security will vary. Most may also be used as a sealer, which is a handy dual function.

Considering the local weather conditions is also essential. Use a darker stain in a harsh climate, as it will fade less quickly. It can save you the trouble of regularly repairing your siding.

The rule of thumb is that darker stains provide more defense than lighter ones. This is because increased pigmentation offers more excellent resistance to UV rays. 

Some people prefer lighter colors because they feel they give just as much protection but are more aesthetically pleasing.


A stain for cedar siding can alter the wood’s natural color, so it’s essential to consider which shade will work best for your project. 

You may get cedar to appear like redwood, for example, by using a stain whose hue is designed to mimic the appearance of that wood.

Thompson water seal benefits

Cedar is available in a variety of light to mid-tone to dark hues. Many prefer leaving it in its original, unaltered coloration because of how striking it can be. There are many alternatives for those who prefer a different hue.

Although cedar is already a light wood, you may want to go even lighter by selecting a light oak or golden pine for the exterior sidings.

Nevertheless, selecting a darker color can give the sidings a warmer look. Stains like mahogany, burnt hickory, and dark walnut will completely transform the look of your cedar.

There is generally the option to alter the color to something utterly strange when working with semi-transparent and solid color stains.

What you decide to do is entirely up to you. You can choose from several solutions appropriate for the siding. Most brands offer stains with a broad color spectrum.

It’s important to remember that achieving a dramatic color shift may require several coats and more time and effort. Especially when transitioning from a dark to a light environment, this might be a significant consideration.

Cleaning Up & Application

Our woodworking experts say a water-based formula is easier to use and maintain.

If it’s your first time using a stain, it is helpful if the stain you choose is easy to apply and clean regardless of how much stain layers you put. 

Read cedar siding reviews and the manufacturer’s instructions to make sure you have everything you need and know what to do.

Cedar Pattern

You should highlight the unique grain pattern of your cedar if it has one. Choices between solid, transparent, and translucent stains are common.

Use a semitransparent stain if the wood’s grain is beautiful, but the color is worn. A translucent stain can be the ideal coating if the texture and color are both fashionable. 

On the other hand, if your wooden structure has a poor appearance, a good finish can cover it up.

Drying Time

A product’s ability to dry quickly is always a significant consideration. Moreover, drying periods vary depending on the material. So, it is essential to have an idea of what to expect.

But, you risk further damaging the surface if you attempt to work on it before thoroughly drying it. So, being aware of the product’s drying time is preferable.

The shorter the drying time, the sooner you can return to working on the area. That way, you won’t have to wait any longer than necessary.

Should You Paint or Stain Cedar Siding?


While painting sidings protects them from the elements, it also wholly masks the wood’s aesthetic value. If you cannot restore the cedar siding’s color, you should consider painting instead. Paint lasts longer and needs less upkeep.

But paint can make the siding look fake, and it’s also expensive.

Stains, unlike paint, rarely chip or flake. The protective and aesthetic benefits of staining are enhanced. Staining cedar is a better option than painting them because it is less expensive.


The best exterior stain for cedar siding can do a better job of bringing out the siding’s natural beauty. The wood’s natural appearance is preserved and protected from moisture and UV rays.

Use a semi-transparent or transparent stain if you want the grain to still show. Additionally,  stains are also considerably less expensive than paints.

Staining Exterior Cedar Siding in 4 Steps

Step #1: Prepare and Clean the Wood

Have the wood ready first. If it has been stained in the past, you should strip it. Use a wood cleaner on bare wood instead of coatings or stains.

Use slight pressure to start cleaning the wood. When you use strippers and cleaners, the cleaners will handle most of the work, so you won’t have to scrub as hard.

Step #2: Neutralize the Wood

Use a wood brightener that also acts as a neutralizer. To ensure the stains penetrate the wood, the wood must be neutralized to a pH of 7. [1]

Let it dry first. Depending on the conditions, this may take many days.

Step #3: Make Sure to Dry the Wood

Use a high-tech moisture meter to check the wood’s surface moisture content.

Step #4: Start Staining the Cedar Sidings Using an Airless Sprayer

Stain the siding regularly and liberally so it may be painted with a thick, even layer.

Oil-based stains can protect the wood from moisture, such as it won’t chip or peel when exposed to snow and rain.

The wood can only be shielded from the sun using a protective stain. To make the wood last for decades and look great the whole time is to maintain it clean and protected from stains.

How Long To Wait for the Stain to Dry After Application?

Several variables affect how long it takes for a stain to dry after being applied, such as the type of stain used, the surface it is being applied to, and the weather.

Oil-based stains often dry more slowly than water-based ones, and damp or chilly weather might further prolong drying times.

Generally speaking, you should give a stain at least 24 hours to dry, though this time frame may be extended for more stubborn stains.

Before applying a finish or using the surface, it is crucial to wait the recommended amount of time suggested by the manufacturer to ensure the stain has been appropriately set. Until the stain is dry, you should also avoid touching the affected area.

How Often Should You Stain Cedar Siding? Should You Seal It After?

Cedar sidings should be stained or treated with a protective coating every 3-5 years, although this can vary depending on various factors.

The frequency of staining or treating cedar sidings depends on factors such as the type of stain or coating used, the climate and weather conditions in your area, the level of sun exposure, and the amount of moisture in the air.

If the color of the cedar siding is fading or the wood is becoming rough or cracked, it may be time to re-stain or reapply a protective coating. 

Inspecting your cedar siding regularly for signs of damage or wear and tear and addressing any issues promptly to prevent further damage is essential.

Proper maintenance and regular cleaning of cedar sidings can help extend the lifespan of your stain or coating and reduce the need for frequent reapplication.

How Long Does Cedar Siding and Exterior Stain Last?

The lifespan of an exterior stain can vary depending on several factors, including the stain type and quality, the condition and type of wood or surface being stained, the level of exposure to elements, and the climate and weather conditions in your area.

Generally, a high-quality exterior stain can last 5-10 years, with some stains lasting even longer under ideal conditions. However, exposure to harsh sunlight, extreme temperatures, moisture, and other weather conditions can cause the stain to break down or fade over time, shortening its lifespan.

It’s important to note that proper preparation and application of the stain can also impact its lifespan.

If the surface is not adequately cleaned and prepared before applying the stain or is not used according to the manufacturer’s instructions, it may not last as long as expected.

Regular maintenance and cleaning can also help extend the lifespan of your exterior stain. It’s essential to regularly inspect your stained surfaces and reapply the stain as needed to maintain its protective qualities and prevent damage to the underlying wood or material.

Tips for Cedar Siding Maintenance

Maintaining your siding should be simple after an excellent stain has been applied. Plants and branches are best kept at least a few inches away from the siding surface since they can provide moisture and may scrape it.

Cleaning the siding regularly and adding a new layer once a couple of years will keep it free of dust and debris. If you don’t have access to a pressure washer, soap and water will do the trick.

There should also be routine checks. This will reveal any damaged areas of wood or regions wearing off too quickly. You can also check for problems with pests like termites and woodpeckers.


Should You Remove the Old Stains on Cedar? And How Do You Prepare Old Cedar?

For optimal results, we recommend that the previous stain be removed first. This is crucial if the stain is flaking and worn. Using tape can help you determine if an old stain must be stripped. Apply it to any section, pull it off, and if you see an existing stain on the tape, then replace it.

Can you paint over the cedar siding that’s stained?

You can, and many people do, so that the wood looks even nicer once it has been stained. But before you put on a new coat of paint, you need to make sure the existing stain is completely dried.

Why cedar sidings are losing color?

Weathering is the primary culprit behind the gradual graying of cedar wood. Untreated wood suffers severe damage from weathering. When cedar is left out in the elements, it quickly loses its reddish hue and turns a drab gray.

Can you apply stain on newly painted cedar siding?

Staining a freshly painted wall is not a good idea. Waiting several months and letting the siding weather is the most effective strategy. After that, stain it according to the instructions. If your stain is unsuitable for the existing one, remove the old stain entirely before application.
