Why Rubio Monocoat Oil Plus 2C Is One of My Favorite Wood Finishes

After hours of building, the last thing you want is a finish that fights you. That's one of the biggest reasons Rubio Monocoat Oil Plus 2C has become one of my favorite finishes. It's easy to use, a little goes a long way, and it leaves a beautiful finish that holds up well.

I've used it on many projects, including my own workbench, which doubles as an assembly table. It's taken a beating for two and a half years now, and the finish has held up impressively well. More recently, I built a table and had it in use within days: my kid was playing with his toys on it after just two days, and there wasn't a mark on it. For me, that kind of real-world experience says a lot about a product.

One of the things I appreciate most about Oil Plus 2C is how forgiving it is. It's pretty foolproof when you follow the prep and application directions. Finishing can be intimidating, especially when you're worried about ruining a project you've put so much work into. Having a finish that's straightforward to apply makes that last step a lot more enjoyable.

Part of that ease comes down to how the product is designed. As the name suggests, it's a one-coat finish, applied once rather than built up in multiple coats like many traditional oils or varnishes. Rubio calls this "molecular bonding technology," which in practical terms means the oil bonds directly to the exposed wood fibers, coloring and protecting the wood in that single application. It preserves the natural texture of the wood without building a thick coating over it.

That also means you don't need much. Applying more product doesn't create more protection, so a small amount covers a surprising amount of wood. The basic process is to prepare the surface, mix the two components as directed, work the oil into the wood, and thoroughly wipe away the excess before letting the piece dry. All excess needs to be removed within 30 minutes of application. I typically remove the excess around 15 minutes after application. Rubio's furniture application instructions walk through the steps in detail.

With Part B mixed in, Rubio allows light handling or use after approximately 24-36 hours under favorable conditions, while full cure takes approximately five days. That's part of why I was pleasantly surprised at how well that table held up after just two days of toy play. Even so, I'd give the finish its full cure time before putting it through heavy use. Proper preparation, removing the excess, and allowing time to cure are all parts of getting a good result.

Personally, I prefer a matte finish on most things. I like being able to see the grain and feel the wood, and Oil Plus 2C gives me the look I'm after. If you prefer a little more sheen, Rubio's SheenPlus is an option for adding a satin appearance.

With 40 colors available, there's plenty of room to find a look that suits your project. My personal favorite is Pure. It brings out the grain and richness of the wood without adding a colored pigment, fitting the natural matte look I'm usually after. It can still deepen the wood's color and give it a wet-wood appearance, especially on lighter species. I always think testing a finish on a scrap from your build is time well spent, since the wood itself plays a big role in the final color.

Another benefit is the ability to make localized repairs. A piece that gets used will eventually show some wear, and being able to address an area without refinishing the entire project is a practical advantage. Durable doesn't mean maintenance-free, but a finish that's easy to care for makes a real difference over time.

For me, Oil Plus 2C brings together the things I want in a finish: simple application, a natural matte appearance, and protection I've been happy with on my own projects. It's a product I enjoy using, and that's why I'm glad to offer it at Crossroads Fine Woodworking.
