Treating Larch Wood
Larch wood is a popular wood type for all kinds of outdoor wood projects, such as larch decking, thanks to its natural durability and beautiful appearance. However, if you want to preserve the wood’s colour and extend its lifespan, it’s important to treat it correctly. One of the most effective methods for treating larch wood is oiling. In this blog, we’ll explore the benefits of oil treatment and how to do it properly.
Why Choose Oil to Treat Larch Wood?
Oil treatment is one of the best methods for protecting larch wood. The oil penetrates deeply into the wood’s pores, which helps protect it against moisture and UV rays. The oil also helps preserve the wood’s natural appearance and structure, keeps the surface flexible, and helps prevent cracking.
For treating larch wood, we recommend either our interior oil Oil Plus 2C or our exterior oil DuroGrit. Both oils enrich the wood with environmentally friendly ingredients, ensuring the wood remains strong, durable, and beautiful.
Outdoor Treatment of Larch Wood
When treating larch wood outdoors with oil, it’s important to follow a thorough cleaning process to ensure the best possible protection. Before applying oil, the wood must be clean and completely dry.
If the wood has already been exposed to changing weather conditions, it may be necessary to lightly sand the surface to remove dirt and grey patina. Use a soft brush and our Rubio Monocoat wood cleaner to remove dirt and old oil residues.
Once the wood is prepared, you are ready to apply oil for outdoor larch wood treatment. Here, we recommend our exterior oil DuroGrit, which provides effective protection against UV rays, rain, snow, and all other weather conditions.
Our DuroGrit oil is also designed with a special molecular bonding technology, meaning you only need to apply one single coat to achieve a perfect result.
Applying DuroGrit Exterior Oil
Once the wood is prepared, cleaned, and free from sanding dust, you can begin applying DuroGrit exterior oil. We recommend applying the oil using a wide brush and working in smaller sections at a time. Allow the oil to cure in the wood to ensure optimal surface protection. After a few days, you will be able to clean and maintain the wood as normal.
Aftercare and Maintenance
To ensure long-lasting protection, it is recommended to re-treat larch wood with oil once a year, depending on weather conditions and the wood’s exposure to sun and rain. It may be beneficial to regularly check the wood’s condition, especially after winter or periods of heavy rainfall. Maintaining a regular outdoor cleaning routine is also important to prevent dirt from penetrating the surface and leaving stains.
Effective Maintenance for Larch Wood
Treating larch wood with oil is an effective way to protect it, especially when used outdoors. The oil penetrates the wood fibres, protects against moisture and UV rays, and enhances the wood’s natural beauty. By following the correct steps for preparation, application, and maintenance, you can ensure your larch wood remains beautiful and durable for many years to come. Remember to re-treat the wood regularly to maintain protection and preserve the warm glow that larch wood is known for.
