In this article, I would like to discuss the factors of surfboards and their discoloration so that you can solve the issue. Let’s get into the detailed information. 

Why Does A Surfboard Turn Yellow? 

Turning a surfboard yellow is a common thing when you see any old surfboard. The top layer of the surfboards turns yellow when it is open in direct sunlight. The top layer of the boards is made of resin. Because of the UV rays, surfboards turn yellow. 

The work of the resin is to protect the foam from any UV damage. Although resin has a UV filter additive, the foam underneath can still be damaged and turn yellow. And the sun can maximize the damage. Exposure to direct sunlight can degrade both the boards with and without UV inhibitors and stabilizers. 

Besides, if there is no layering and the foam is unprotected, this can also be a reason to turn the boards yellow. So, if you don’t protect your foam core, it turns yellow for sure. All these things encourage the yellowing process. 

To be practical, it’s impossible to keep your surfboards inside and away from sunlight. So, turning yellow is common for almost all surfboards. And at one point, you will need to repair this damage. 

Causes for Surfboard to Turn Yellow 

Several causes are there that can turn your surfboard yellow. The main cause of it is exposure to direct sunlight. Besides, it can happen if the foam is unprotected. Check out the reasons why surfboards turn yellow over time. 

  • Unprotected Foam 

If your surfboard is not protected and covered properly, you will be highly likely to damage it. Prolonged exposure is also a reason for the damage. Generally, the foam core of the board is covered with epoxy resins and fiberglass. The foam underneath should be protected with some additives and a resin top layer. It helps to protect it from any breaks. 

But if it doesn’t have the proper protection, the intense and high amounts of radiation can enter into the unprotected foam and discolor them. Thus, it turns yellow. In this case, you will use salt water to minimize the effects. 

  • UV Radiation 

One of the main reasons for turning the surfboards yellow is UV radiation. When you are out with your surfboard on a beach in the sun, it will surely get yellow because of the prolonged exposure and light. The power of UV radiation can damage the board surface just like it does on the skin and sunburn. 

In this way, discoloration occurs when the foam is covered with epoxy resin or polyester resin, it won’t affect, even if there is intense UV radiation. The reason is it contains a UV filter additive that becomes helpful to minimize the effect. 

Resins help to protect the surfboard for a long time. That doesn’t mean it will protect in the same way if you keep your board under high exposure for too long. If it is white surfboards or fiberglass boards, the effects of discoloration will be more visible. The main reason is the UV light.
