If you have a sauna at home or are planning to buy one, it’s important to understand wood staining and protection first. Over time, saunas are exposed to the elements and can suffer from inevitable damage, such as mold, fungus, and rot. Wood staining and protection are essential options to prevent these issues. In this blog, we provide a comprehensive guide on how to stain an outdoor sauna, helping ensure that your home sauna remains a stylish and durable oasis for years to come.

Why Should You Sauna Wood Stain Protection?

When we take action, it's usually to address a specific need, and staining the wood in a sauna is no exception. Alphasauna manufacturers explain its importance as follows:

Protection Against UV Rays

For outdoor saunas, prolonged exposure to UV rays can cause wood to fade and become brittle, compromising the structure’s stability and appearance. When wood stained and protected, the UV-blocking components in the stain form a thin protective film on the surface, preventing direct UV contact. Additionally, some stains contain anti-fading and UV-absorbing ingredients, helping the wood retain its original color over time.

Wood Preservation

Wood is a natural material, which makes it susceptible to insects, fungi, and mold. Applying a wood stain to your sauna helps create a less hospitable environment for these threats, extending the sauna’s lifespan. Staining also reduces the effects of water stains, dirt, and scratches, making routine maintenance easier.

Enhanced Aesthetics

After prolonged use, a sauna’s appearance naturally changes, often losing its initial beauty and taking on signs of age. Wood staining can restore the sauna’s natural beauty and highlight its texture without altering its structure. Staining is an essential choice for those who appreciate a natural, rustic, modern look, and it is key to creating a beautiful home sauna oasis.

Tip: If your sauna is made from high-quality woods like cedar, staining may not be necessary.

Sauna Staining and Protection Guide

Now that we know why staining is important, how do we go about it? Just as there are different types of saunas, there are also three main types of stains, each with unique characteristics. Let’s explore the pros and cons of each to help you choose the best option.

3 Types of Sauna Stains

Oil-Based Stains

Known for their deep penetration and durability, oil-based stains are excellent for waterproofing and preserving wood, offering long-lasting protection and rich color. But, they can be challenging to apply and clean and may require solvents for removal.

Water-Based Stains

In contrast to oil-based stains, water-based stains don’t penetrate as deeply, but they are easier to clean and emit fewer volatile organic compounds (VOCs), making them a safer choice for both users and the environment. Water-based stains provide solid protection and color retention.

Natural Stains

The final type of stain is ideal for those who prefer a natural approach, though it may require more frequent application. Made from natural ingredients like linseed oil, beeswax, and plant extracts, these stains are non-toxic, environmentally friendly, and enhance the wood's natural beauty.

How to Wood Stain Sauna Protection

Once you've learned about staining and protecting wood, you can move on to the next step: staining the wood in your sauna. Regardless of the stain type you choose, the process follows these steps:

Clean the Sauna Surface

Before staining, thoroughly clean the sauna's surface to remove any dirt, debris, or mold, and allow the wood to dry completely. You can use a mild soap and water solution or a professional wood cleaner with a soft brush. Avoid using harsh cleaners.

Sand the Wood and Protect the Surrounding Area

Use medium-grit sandpaper to sand the wood, which helps the stain penetrate more effectively. To protect the surrounding area, lay down dust cloths or plastic sheeting. This prevents unwanted mess from sanding and staining.

Apply the Stain

Choose a dry, overcast day to avoid direct sunlight, which can damage the wood during the staining process. Apply the stain evenly along the wood grain using a brush, roller, or sprayer. Allow 24 to 48 hours for the first coat to dry. If a deeper color is desired, wait until the first coat is fully dry before applying a second coat.

Apply a Protective Sealer (Optional)

To further extend the life of the wood in your sauna, consider adding a clear protective sealer on top of the stain. This layer offers more protection from moisture, UV rays, and other elements, preventing premature fading and damage.

FAQ

Q: How often should wood staining and protection be applied?

A: Re-staining is typically recommended every 1 to 3 years, depending on the level of wear and exposure the wood has experienced.

Q: Does Stain Protect Wood From Water?

A: Basic staining can offer some moisture protection, but it does not create a thick waterproof barrier and may not provide long-term, comprehensive protection. But, when combined with a sealant, staining can create a waterproof layer on the wood surface for stronger water resistance.

Q: Are there alternatives to staining for protecting sauna wood?

A: If you’re still considering a sauna buy, you might opt for more weather-resistant wood types like cedar, hemlock, or heat-treated wood. If you already own a sauna, adding a shelter or applying a wood sealer can also help protect the wood.

Q: Will staining damage sauna wood?

A: Staining can enhance the appearance of the wood, but using the wrong type of stain can cause issues, such as uneven coverage or moisture retention. It’s important to choose a stain appropriate for sauna wood.
