When it comes to choosing the best polyurethane for cornhole boards, there are a few factors to consider. The primary purpose of applying polyurethane to cornhole boards is to protect the wood from weathering, moisture, and general wear and tear. You’ll want a polyurethane that provides a durable, long-lasting finish while enhancing the appearance of the boards.
Here are a couple of factors that are worth checking out before making a puchase
5 Factors to Consider:
Durability
When selecting a polyurethane for your cornhole boards, durability is a crucial factor to consider. The polyurethane should provide excellent protection to withstand frequent use and exposure to the elements. Look for a product that is specifically formulated to be tough and resistant to scratches, moisture, and general wear and tear. Most exterior polyurethane will be top choice.
Water-based vs oil-based polyurethane
Consider the ease of application when selecting a polyurethane for your cornhole boards. You’ll need to choose between a water-based or oil-based polyurethane, each with its own advantages and considerations.
Oil-Based Polyurethane
Oil-based polyurethanes are generally easier to work with during application. They have a longer open time, meaning they take longer to dry, allowing for more forgiving application. This gives you more time to work with the polyurethane and ensures a smoother finish. However, one drawback of oil-based polyurethane is its slow drying time. It can take several hours or even days to fully dry and cure. Additionally, oil-based polyurethane tends to have a strong odor that can linger for up to 30 days, requiring proper ventilation.
Water-Based Polyurethane
On the other hand, water-based polyurethanes may present some challenges during application. They have a shorter open time, meaning they dry relatively quickly once applied. This requires more skill and attention to detail to ensure a smooth and even application. However, the quick dry times, allows layering multiple coats within the day hence faster project completion. They also tend to have minimal odor, making them more pleasant to work with.
Consider your comfort level with the application process and your desired timeline for project completion when choosing between water-based and oil-based polyurethanes. If you prefer more forgiving application and don’t mind longer drying times and odor, oil-based polyurethane may be a suitable option. Conversely, if you prioritize quick drying, minimal odor, and superior protection, water-based polyurethane may be the better choice. Ultimately, selecting the right type of polyurethane will ensure a smooth and successful application on your cornhole boards.
Desired appearance
When considering the finish for your cornhole boards, you have a few options to choose from that will impact the overall look and aesthetic. Let’s explore these options and their implications.
- Satin Finishes: Satin finishes provide a more subtle sheen compared to glossy finishes. They strike a balance between a high-gloss shine and a more natural appearance. This finish is a popular choice for those seeking a refined and elegant look for their cornhole boards.
- Matte Finishes: Matte finishes maintain the original appearance of the wood, offering a more understated and rustic aesthetic. These finishes have a low sheen or no sheen at all, giving your cornhole boards a more muted and natural look. Matte finishes are often preferred by those who appreciate a more organic and textured appearance.
- Gloss Finishes: Gloss finishes offer a high-shine, reflective surface that brings out the natural beauty of the wood grain. This finish is often chosen by those who prefer a bold and polished look for their cornhole boards. Gloss finishes can create a visually striking appearance, especially when applied to high-quality, well-crafted boards.
- Yellowing and Aging: It’s important to note that some polyurethane finishes may have a tendency to yellow over time, especially when exposed to sunlight. This aspect is where the water-based vs. oil-based debate becomes relevant. Water-based polyurethanes typically exhibit less yellowing compared to their oil-based counterparts. This is an important consideration if you want to maintain the original color and clarity of your cornhole boards over the long term.
UV Protection:
If your cornhole boards will be exposed to sunlight, it’s essential to select a polyurethane that offers UV protection. UV rays from the sun can cause fading and discoloration of the wood over time. Look for a polyurethane that has UV inhibitors or additives designed to block or minimize the damaging effects of UV radiation. UV protection will help preserve the vibrant colors and overall appearance of your cornhole boards, ensuring they stay visually appealing for longer periods.
