Why Do Surfboards Turn Yellow?
If you're a surfer, you've probably noticed that your surfboard can turn yellow over time. This yellowing can be unsightly and may even lead you to worry about the condition of your board. But why do surfboards turn yellow in the first place? In this blog post, we'll explore the reasons behind surfboard yellowing and what you can do to prevent it. From the materials used in surfboard construction to the effects of sunlight and water, we'll break down the science behind this phenomenon and provide tips on how to keep your surfboard looking its best.
The Role of Resin in Surfboard Construction and Why It Yellows
Resin is a key component in the construction of surfboards. It is used to coat the foam core and provide a protective layer that helps the board maintain its shape and strength. However, the chemical processes involved in resin polymerization can also cause surfboards to turn yellow over time.
UV exposure is one of the main factors that can cause surfboard yellowing. When exposed to the sun's rays, the resin begins to break down and lose its clarity. This process is known as photodegradation and can cause the surfboard to turn yellow or even brown. In addition to UV exposure, oxygen can also interact with resin and cause it to yellow over time.
Despite the yellowing effect, resin is still an essential component in surfboard construction. To minimize the risk of yellowing, it's important to use high-quality resin and to limit the board's exposure to sunlight. By taking these steps, surfers can ensure that their boards maintain their structural integrity and aesthetic appeal for years to come.
UV Radiation and Its Impact
UV radiation is a primary factor in surfboard yellowing. When surfboards are exposed to UV rays, the resin polymers begin to break down, leading to yellowing and other forms of discoloration. Over time, this can cause the board to lose its clarity and become unsightly.
Geographical factors also play a role in the intensity of UV radiation exposure. In regions with high levels of sunlight, such as California or Hawaii, surfboards are more susceptible to yellowing. On the other hand, in areas with a lot of clouds or rain, such as the Pacific Northwest or England, surfboards are less likely to be yellow.
To prevent surfboard yellowing caused by UV radiation, surfers can take protective measures such as using high-quality UV-resistant resin and storing their boards in a cool, dry place when not in use. Additionally, surfers should limit their boards' exposure to sunlight by using Surfboard Bags or storing them in the shade. By taking these steps, surfers can maintain the appearance and longevity of their surfboards.
Oxygen Exposure and Oxidation
In addition to UV radiation, oxygen exposure can also contribute to surfboard yellowing. When surfboards are exposed to oxygen, the resin components begin to oxidize, leading to discoloration and yellowing. This process is known as oxidation and can cause surfboards to lose their clarity and aesthetic appeal over time.
To minimize the risk of yellowing caused by oxygen exposure, surfers should consider their storage conditions. Air-tight storage can help prevent oxygen from reaching the surfboard and causing oxidation. On the other hand, storing the board in an open and well-ventilated area can help reduce the risk of mold and mildew growth.
Lets face it, you can’t keep your board out of oxygen. But you can choose to invest in high quality resin.
Other strategies to outweigh the impact of oxygen exposure include using UV-resistant resin, limiting the board's exposure to sunlight, and storing the board in a cool, dry place. By taking these steps, surfers can protect their boards from the effects of oxidation and maintain their appearance and structural integrity over time. FARO Surfboard Bags play a big role in helping protect your boards for the sun by keeping them cool, dry, and in good condition.
Impact of Water Quality
Water quality can also impact the yellowing of surfboards. Saltwater, in particular, can accelerate the yellowing process due to its corrosive nature. When surfboards are exposed to saltwater, the salt can penetrate the resin and cause it to break down, leading to yellowing and discoloration. Additionally, contaminants in the water, such as oil, pollution, and algae, can also contribute to surfboard yellowing.
Freshwater, on the other hand, is less likely to cause yellowing. However, freshwater with high levels of contaminants can still have a negative impact on surfboard appearance and longevity. It's important to rinse surfboards with fresh water after each use to remove any salt or contaminants that may have accumulated on the board.
To minimize the impact of water quality on surfboard yellowing, surfers should rinse their boards with fresh water after each use and avoid exposing their boards to contaminated water. Additionally, surfers can use a protective cover or bag when transporting their boards to prevent exposure to saltwater and contaminants.
Ways to Prevent or Minimize Yellowing
Surfboard yellowing may be an inevitable part of a surfboard's life, but there are ways to prevent or minimize it. Here are some ways to keep your surfboard looking its best:
1. Proper Board Maintenance and Storage Practices
Proper board maintenance and storage practices can also help prevent yellowing. Rinse your board with fresh water after each use to remove any salt or contaminants, and store it in a cool, dry place away from direct sunlight.
2. Choosing Resins with UV Stabilizers
When purchasing a surfboard, look for resins that contain UV stabilizers. These resins are designed to resist the effects of UV radiation, which can help prevent yellowing.
3. Regular Cleaning and Waxing Routines
Regular cleaning and waxing routines can also help prevent yellowing. Cleaning your board regularly can remove any contaminants that may contribute to yellowing, while waxing can help protect the board from UV radiation and oxidation.
4. FARO's surfboard bags
Investing in a high-quality surfboard bag, such as those offered by FARO, can also help prevent yellowing. FARO's bags are designed with durable, eco-friendly materials and feature UV-resistant coatings that help protect your board from the sun's harmful rays.
Final Thoughts
In conclusion, while surfboard yellowing may be unavoidable, there are steps that surfers can take to minimize its impact. By practicing proper board maintenance, and investing in a high-quality surfboard bag, surfers can prolong the life of their surfboards and keep them looking their best.
