Advantages Of Polyurethane

Polyurethane has gained popularity among woodworkers and DIY enthusiasts for good reason. Here are some of the key benefits:


Polyurethane provides a tough protective layer that can withstand everyday wear and tear. It creates a hard surface that is resistant to scratches, stains, and moisture, ensuring that your wood surface remains in excellent condition for years to come.

Wide Range of Finishes

One of the significant advantages of polyurethane is its versatility in terms of finishes. It is available in multiple options, including gloss, semi-gloss, and satin finishes. This allows you to choose the level of sheen that best suits your aesthetic preferences and the specific needs of your project.

Easy Application

Polyurethane is relatively easy to apply using a brush, roller, or sprayer. It dries quickly, enabling you to complete your project in a timely manner. Additionally, it can be easily recoated without the need for extensive surface preparation.

Protection against UV Rays

Polyurethane provides excellent protection against the damaging effects of ultraviolet (UV) rays. This means that your wood surface will be less likely to fade or discolor when exposed to sunlight, making it an ideal choice for outdoor applications.

Disadvantages Of Polyurethane

While polyurethane offers many advantages, it also has some drawbacks that should be taken into consideration:

Strong Odor

When applying polyurethane, it emits a strong odor that can be unpleasant and may require proper ventilation during the application process. It is essential to ensure that you work in a well-ventilated area to minimize any potential health risks associated with the fumes.

Yellowing Over Time

One of the downsides of polyurethane is that it has a tendency to yellow over time, especially when exposed to sunlight. This can affect the appearance of lighter wood surfaces and may require periodic maintenance to maintain the desired color.

Difficult to Repair

If the polyurethane on your wood surface gets damaged or starts to wear off, it can be challenging to repair. Unlike other finishes, such as Rubio Monocoat, which can be spot repaired, polyurethane often requires a complete refinish of the entire surface to restore its original appearance.

Considering the benefits and drawbacks of polyurethane will help you make an informed decision when deciding whether to use it as a finish for your Rubio Monocoat project. While it offers durability, versatility, and protection, it is crucial to be aware of the strong odor, potential yellowing, and the difficulty involved in repairing polyurethane finishes.

Advantages And Disadvantages Of Rubio Monocoat

Rubio Monocoat is a popular choice for finishing wood surfaces due to its unique characteristics and benefits. However, like any product, it also has its limitations. Understanding the advantages and disadvantages of Rubio Monocoat can help you make an informed decision when choosing a finish for your wood projects.

Benefits Of Rubio Monocoat

  • Easy application: Rubio Monocoat offers a simplified application process. Unlike conventional polyurethane finishes that require multiple coats and extensive preparation, Rubio Monocoat only needs a single application for most projects. This saves you time and effort while still achieving excellent results.
  • Natural appearance: One of the biggest advantages of Rubio Monocoat is its ability to enhance the natural beauty of wood. It penetrates deep into the fibers, bringing out the rich colors and unique grain patterns. The result is a beautiful, matte finish that showcases the wood’s natural allure.
  • Durable and long-lasting: Rubio Monocoat provides exceptional protection for your wood surfaces. Once cured, it forms a strong molecular bond with the wood, creating a durable, waterproof barrier. This makes it resistant to scratches, wear, and common household spills. With proper care, Rubio Monocoat finishes can last for many years.
  • Environmentally friendly: If you are concerned about the environmental impact of finishing products, Rubio Monocoat is a great choice. It is made from natural ingredients and contains no harmful chemicals or volatile organic compounds (VOCs). This means you can achieve a stunning finish while minimizing your ecological footprint.
  • Repairability: Accidents happen, and wood surfaces can get damaged over time. The advantage of Rubio Monocoat is that it allows for spot repairs instead of having to refinish the entire surface. Whether you need to fix a scratch or refresh the finish, Rubio Monocoat enables you to address specific areas without much hassle.

Limitations Of Rubio Monocoat

  • Limited color options: While Rubio Monocoat offers a range of colors, the variety is not as extensive as what you might find with other finishing products. If you have a specific color in mind, it is essential to check if it is available in the Rubio Monocoat line.
  • Not suitable for high-traffic areas: Rubio Monocoat is durable and resistant to many types of wear, but it may not hold up as well in high-traffic areas like floors. Heavy use and frequent foot traffic can cause the finish to wear off more quickly, requiring more frequent touch-ups or reapplication.
  • Requires proper surface preparation: While the application process for Rubio Monocoat is straightforward, it is crucial to prepare the wood surface properly beforehand. This includes sanding and cleaning the wood to ensure optimal adhesion. Skipping this step may result in an uneven finish or poor durability.
  • Longer curing time: Unlike some quick-drying finishes, Rubio Monocoat requires a longer curing time. It can take up to 36 hours for the finish to fully cure, depending on environmental conditions. This means you will need to allow sufficient drying time before subjecting the wood to regular use.
  • Can darken some woods: Rubio Monocoat reacts differently to different types of wood. While it enhances the natural color of most woods, it may darken certain varieties. If you have a light-colored wood that you want to keep as light as possible, it is essential to test the Rubio Monocoat on a small, inconspicuous area first.

Process And Considerations For Applying Polyurethane Over Rubio Monocoat

When it comes to finishing wood surfaces, Rubio Monocoat has established itself as a popular choice for its unique qualities. However, there may be instances where you might want to add an additional layer of protection or change the overall appearance of the wood. In such cases, applying polyurethane over Rubio Monocoat can be a suitable option.

Preparation Of Surface

Before you begin the process of applying polyurethane over Rubio Monocoat, proper surface preparation is crucial to ensure optimal adhesion and a smooth, consistent finish. Here are a few steps to follow:

  1. Clean the surface: Begin by thoroughly cleaning the wood surface using a mild detergent or wood cleaner. This will help remove any dirt, dust, or contaminants that could interfere with the adhesion of the polyurethane.
  2. Sand the surface: Use a fine-grit sandpaper to lightly sand the Rubio Monocoat finish. This step helps create a textured surface that allows the polyurethane to adhere effectively. Be careful not to sand too aggressively, as this could damage the underlying wood.
  3. Remove dust: After sanding, wipe down the surface with a clean and lint-free cloth or tack cloth to remove any sanding dust. Ensuring a dust-free surface is essential for achieving a smooth and flawless polyurethane finish.

Selection Of Polyurethane

Choosing the right type of polyurethane is crucial to ensure compatibility with Rubio Monocoat and achieve the desired results. There are a few key factors to consider:

  • Type of polyurethane: Select a polyurethane that is compatible with Rubio Monocoat and is suitable for your desired finish. Water-based polyurethane is a popular choice due to its low odor, quick drying time, and easy cleanup. However, oil-based polyurethane offers a more durable and amber-toned finish.
  • Finishing properties: Consider the level of sheen you want to achieve with the polyurethane. Polyurethanes are available in a range of sheen options, from high gloss to matte. Choose the one that complements your aesthetic preferences and the intended use of the wood surface.

Application Techniques

Applying polyurethane over Rubio Monocoat requires attention to detail and careful application. Follow these guidelines for a successful outcome:

  1. Even application: Using a high-quality brush or applicator, apply the polyurethane evenly across the wood surface. Work in thin and consistent coats to prevent drips, bubbles, or uneven drying.
