What issue can lead to alligatoring in gel coat?

• A. Applying gel coat too thickly
• B. Applying gel coat at the right temperature
• C. Applying gel coat too thinly
• D. Applying laminate too late

Answer: (C)

Alligatoring in gel coat refers to the development of a pattern of cracks or crazing that resembles the skin of an alligator. This issue can arise primarily from applying gel coat too thinly. When the gel coat is insufficiently applied, it does not have the necessary thickness to provide adequate protection and flexibility. Consequently, this can lead to stresses that the gel coat cannot accommodate, resulting in the formation of cracks. This phenomenon is exacerbated by factors such as environmental conditions, temperature variations, and the possible interactions with underlying substrates. A thin layer may also cure too quickly or unevenly, further contributing to the cracking. Understanding the importance of the correct application thickness is crucial for preventing issues like alligatoring, as a properly applied gel coat should provide both the aesthetic finish desirable in marine applications and functional protection against moisture and UV degradation. Thus, ensuring that the gel coat is applied at the appropriate thickness is key to maintaining its integrity and longevity.
