1. Safe Wood Finish – Tried & True Varnish Oil
The Tried & True Varnish Oil is a versatile and food-safe non-film forming varnish that is made using a traditional Shaker recipe from the 1800s. The varnish is formulated with only two ingredients, natural pine resin and linseed oil, both of which are 100% renewable, natural, and safe for food and skin contact.
Unlike other varnishes, there is no need for personal protective equipment or ventilation while using it, as it is completely petrochemical-free and heavy metal-free. The pine resin in this varnish hardens over time, making it the most scratch-resistant Tried & True product. Once the linseed oil has cured, it can be buffed to a higher sheen.
This varnish can be applied over penetrating oil-based stains, other natural oil finishes, and milk paint, making it perfect for use on a variety of projects such as cabinetry, flooring, tool handles, wooden doors and trim, chairs, benches, gun stocks, jewelry boxes, banisters, railings, or any other project where safety and scratch resistance are paramount.
What sets Tried & True products apart is their infinite repairability and longevity, lasting longer than a lifetime when properly maintained. Unlike other varnishes, the Tried & True Varnish Oil does not produce yellow plastic flakes as it ages. It is made of 100% solids, with no fillers or solvents, which means that a little goes a long way.

Best Varnish For Outdoor Wood FAQs
Are there any eco-friendly varnish options for outdoor wood?
Yes, there are eco-friendly varnish options available for outdoor wood. Traditional varnishes contain harmful chemicals such as volatile organic compounds (VOCs) that can harm the environment and human health. However, there are now varnishes that are made from natural and non-toxic ingredients that are safer for the environment and for people.
One such eco-friendly varnish option is a water-based varnish. Water-based varnishes contain lower levels of VOCs and are easy to clean up with water. They also dry quickly and provide a clear finish that protects the wood from the elements.
Another eco-friendly option is a plant-based varnish. These varnishes are made from natural ingredients such as linseed oil, beeswax, and plant resins. They are non-toxic, biodegradable, and provide a durable finish that protects the wood from moisture and UV rays.
When looking for an eco-friendly varnish option for outdoor wood, be sure to look for products that are certified by reputable organizations such as Green Seal or the Forest Stewardship Council (FSC). This will ensure that the product meets rigorous environmental standards and is truly eco-friendly.
Can I use the same varnish on both horizontal and vertical outdoor wood surfaces?
Yes, you can use the same varnish on both horizontal and vertical outdoor wood surfaces. However, it is important to choose a varnish that is appropriate for the specific type of wood and the intended use. For example, if the wood is exposed to harsh weather conditions, it is recommended to choose a varnish that is specifically designed for outdoor use and is UV-resistant. Additionally, it is important to consider the level of foot traffic and wear and tear that the wood will be exposed to, as this may impact the type of varnish that is most suitable. It is always best to consult with a professional or do thorough research before selecting a varnish to ensure that it will provide the necessary protection and durability for your specific outdoor wood surface.
Can varnish enhance the natural color and beauty of outdoor wood?
Yes, varnish can enhance the natural color and beauty of outdoor wood. Varnish is a type of protective coating that is frequently used to protect wooden surfaces from moisture, UV rays, and other environmental factors that can cause damage or wear over time. When applied to outdoor wood, varnish can help to bring out the natural colors and grains of the wood, making it look richer and more vibrant.
In addition to enhancing the natural beauty of the wood, varnish can also help to protect it from damage caused by exposure to the elements. This can help to extend the lifespan of outdoor wood furniture, decks, and other structures, making them more durable and long-lasting.
However, it is important to choose the right type of varnish for your outdoor wood surfaces, as some types may be better suited to certain types of wood or environmental conditions than others. Consulting with a professional or doing some research on the best type of varnish for your particular project can help ensure the best possible results.
How do I properly prep outdoor wood surfaces before applying varnish?
Proper preparation of outdoor wood surfaces is crucial before applying varnish to ensure a smooth and long-lasting finish. Start by cleaning the wood thoroughly to remove dirt, debris, and any previous coatings. Use a wood cleaner or a mixture of water and mild detergent to scrub the surface with a stiff-bristled brush. Rinse it thoroughly with water and let it dry completely.
Next, sand the wood surface using a medium-grit sandpaper to remove any roughness or unevenness. Sanding also helps the varnish to adhere better. Make sure to sand in the direction of the wood grain to avoid creating scratches or marks. After sanding, wipe off any dust with a clean, damp cloth and let it dry.
If the wood has any knots or imperfections, apply a wood filler or putty to fill them in. Smooth it out with a putty knife and let it dry completely before sanding it down.
Finally, apply a wood conditioner to the surface to help the varnish to penetrate evenly and reduce blotchiness. Allow the conditioner to dry according to the manufacturer's instructions before applying the varnish.
By properly prepping the outdoor wood surface before applying varnish, you can ensure a beautiful and durable finish that will protect the wood for years to come.
How often do I need to reapply varnish to outdoor wood surfaces?
The frequency of reapplying varnish to an outdoor wood surface mainly depends on various factors such as the quality of the varnish, weather conditions, and the amount of exposure to sunlight, moisture, and other environmental factors. In general, it is recommended to reapply varnish every 2-3 years for optimum protection and durability. However, if you notice any signs of wear and tear, such as peeling, cracking, or fading, it is best to recoat the surface immediately to prevent further damage. Additionally, it is essential to clean the surface thoroughly before applying varnish to ensure that the new coat adheres properly. Regular maintenance, including cleaning and oiling, can help prolong the life of the varnish and reduce the need for frequent recoating. Overall, the frequency of reapplication may vary depending on the specific conditions and usage of the outdoor wood surface.
Should I choose an oil-based or water-based varnish for outdoor wood?
Choosing between an oil-based or water-based varnish for outdoor wood depends on several factors. Both types of varnishes have their advantages and disadvantages, and you need to consider your project's specific needs before making a decision.
Oil-based varnishes are durable and provide excellent protection against moisture, UV rays, and other weather conditions. They are also easy to apply and provide a glossy finish. However, oil-based varnishes can yellow over time and take longer to dry, which can be inconvenient if you need to apply multiple coats.
On the other hand, water-based varnishes dry faster and don't yellow over time. They are also more environmentally friendly and have a lower VOC (volatile organic compound) content. However, they are not as durable as oil-based varnishes and may require more frequent reapplication.
Ultimately, the choice between oil-based or water-based varnish for outdoor wood depends on your preference, the level of protection you need, and the specific conditions your project will be exposed to. If you want a more durable and long-lasting finish, then an oil-based varnish may be the better choice. However, if you prioritize a faster-drying, more environmentally friendly option, then a water-based varnish may be more suitable.

4. Ease of application: Some varnishes require multiple coats and can be difficult to apply evenly. Look for a product that is easy to apply and dries quickly.

Which varnishes provide the longest-lasting protection for outdoor wood?
When it comes to protecting outdoor wood, choosing the right varnish is crucial. The longevity of the protection depends on the type of varnish used. Generally, the varnishes that provide the longest-lasting protection for outdoor wood are those that contain polyurethane or epoxy.
Polyurethane varnish is a popular choice for outdoor wood due to its excellent durability and resistance to UV rays, water, and harsh weather conditions. It is available in both oil-based and water-based formulas. Oil-based polyurethane varnish provides longer-lasting protection but can yellow over time, while water-based polyurethane varnish dries clear and is more environmentally friendly.
Epoxy varnish is another option for outdoor wood protection. It is extremely durable and resistant to water, UV rays, and extreme temperatures. However, it can be difficult to apply and requires specific preparation and application techniques.
In conclusion, for the longest-lasting protection for outdoor wood, polyurethane varnish (oil-based or water-based) and epoxy varnish are excellent choices. It is important to ensure proper application techniques and maintenance to ensure the longevity of the protection.
