Staining Exterior Wood Siding – Reasons to Do It Periodically

The allure of a wooden exterior on a home is timeless. Wood siding offers a classic, warm aesthetic that many homeowners cherish. However, to keep this beauty intact, periodic staining is important.

Staining exterior wood siding is more than a routine maintenance task; it’s a shield of protection for your home. In this article, we’ll talk about the significance of regular staining for wood siding and why it’s necessary to maintain a stunning exterior.

Why Exterior Wood Siding Needs Periodic Staining?

Why Exterior Wood Siding Needs Periodic Staining?

Wood is naturally vulnerable to various elements, such as rain, snow, and harsh sunlight, which can cause it to degrade over time. Additionally, insects and fungi find wood appealing, leading to potential infestations and rot. 

Here’s where staining proves to be a game-changer. Staining acts as a protective barrier, warding off moisture seeping into the wood. It serves as a reliable UV protectant, preventing sun damage, and deters pests and fungi from making wood their home. 

Here are some key reasons your exterior wood siding needs periodic staining: 

Exposure to Weather Elements

Wood siding is constantly exposed to the elements—sun, rain, snow, and fluctuations in temperature. Over time, this exposure leads to wear and tear. Rain can cause swelling and warping, and exposure to sunlight can fade the natural color and finish of the wood.

Insect Infestations

Wood is a prime target for insects such as termites, carpenter ants, and wood-boring beetles. These pests can cause significant damage, hollowing out the wood and compromising its structural integrity.

Staining, however, acts as a powerful defense mechanism against these threats in the following ways:


Barrier Against Moisture

Staining creates a protective barrier on the wood’s surface, preventing moisture from seeping into the grains. The culprit is moisture absorption, which can lead to warping, rot, and mold growth. 

Staining the wood repels water, ensuring the wood remains strong and intact even in humid conditions.

UV Protectant

Sunlight, especially the UV rays, can cause the wood to deteriorate, fade, and lose its luster. Stains contain UV-blocking elements that act as a shield, preserving the wood’s natural color and texture, thus prolonging its life.

Deters Pests and Fungi

Stains often contain components that deter insects and fungi. The chemicals in the stain make the wood less appealing to pests, reducing the risk of infestations.

Benefits of Regular Wood Siding Staining

Benefits of Regular Wood Siding Staining

1. Prevents Water Absorption

Wood’s tendency to absorb water can result in warping, swelling, and, eventually, rot. Staining forms a protective layer, inhibiting water absorption and preserving the wood’s structural integrity.

2. UV Ray Protection

Sun’s UV rays can cause wood to fade and deteriorate over time. Staining protects against harmful UV rays, maintaining the wood’s color and finish.

3. Guard Against Wood Rot

Wood rot is a homeowner’s nightmare. Staining creates a barrier that helps prevent the growth of mold, mildew, and wood-rotting fungi, ensuring your siding stays in prime condition.

4. Customization and Aesthetics

Stains come in various hues and tones, allowing you to customize the look of your exterior. From natural finishes to bolder shades, you can choose a stain that aligns with your home’s style and your taste.


5. Quick Application and Drying

Modern staining products are designed for easy application and quick drying. This means less downtime during the staining process, allowing you to enjoy the benefits sooner.

6. Preserves Resale Value

A well-maintained exterior significantly enhances the overall curb appeal of your home. This heightened curb appeal can positively influence potential buyers, maintaining or even increasing the resale value of your property.

7. Eco-Friendly Choice

Staining promotes sustainability by extending the life of the wood. When you regularly stain and maintain your wood siding, you reduce the demand for new wood, contributing positively to the environment.

8. Ease of Cleaning

Stained wood siding is easier to clean and maintain. Dust, dirt, and grime can be washed off effortlessly, keeping your exterior looking fresh and vibrant.


How to Properly Stain Exterior Wood Siding?

Staining exterior wood siding is an art that involves following several steps to ensure a successful and long-lasting finish, including the following:

1. Preparing the Wood Surface

Cleaning: Remove any dirt, dust, and debris from the wood siding using a power washer (use a low-pressure setting) or a mixture of water and mild soap. Ensure the surface is completely clean and free from any residue.

Sanding: Sand the wood surface to create a smooth and even base for the stain. Start with rough-grit sandpaper and gradually move to finer grits for a polished finish.

Drying: Allow the wood siding to dry thoroughly before applying the stain. Ensure the surface is entirely moisture-free to allow the stain to adhere effectively.

2. Choosing the Right Stain

Wood Type: Consider the type of wood you have and its porosity to select the appropriate stain. Hardwoods and softwoods may require different types of stains for optimal results.

Transparency: Decide on the level of transparency you desire – transparent, semi-transparent, or solid stain. Transparent stains allow the natural grain to show, while solid stains offer complete coverage.

Climate Considerations: Choose a stain that suits your local climate, providing adequate protection against weather elements. Go for UV-resistant stains to prevent fading in areas with intense sunlight.


3. Application Techniques

Brushing: Use a high-quality brush for precision and control over the application. Work in the direction of the wood grain, ensuring even coverage.

Rolling: Ideal for larger surface areas to achieve a more consistent application. Use a roller appropriate for stains and a back brush for an even finish.

Spraying: Suitable for larger projects and reaching difficult areas. Use an airless sprayer for best results.

4. Post-Staining Care and Maintenance

Drying: Allow the stain to dry before any contact or exposure to moisture. For proper drying, the area should be well-ventilated.

Inspect Regularly: Periodically check the stained surface for any signs of wear, damage, or need for re-staining. Address any issues promptly to maintain the stain’s effectiveness.

Regular Cleaning: Clean the stained wood siding periodically to remove dirt and maintain its appearance. Use a gentle, wood-safe cleanser and a soft brush to avoid damaging the stain.



Periodic staining of exterior wood siding should be a priority for homeowners who want their wood siding to remain healthy and beautiful. It is a proactive measure that sustains the visual appeal and extends the lifespan of your home’s exterior. Staining ensures that your wood siding remains robust and attractive by preventing water absorption, protecting against UV rays, and guarding against wood rot.

So, let this guide be a gentle nudge, a reminder of the significance of periodic staining. Take action, embrace this maintenance routine, and safeguard your exterior wood siding. Your home will thank you with timeless charm and lasting elegance.
