The gel coat surface of a mold should be protected from what while it is in storage?

The gel coat surface of a mold is crucial for ensuring the quality and finish of the composite materials that will be applied to it. To maintain the integrity of the gel coat while the mold is in storage, it is important to protect it from several environmental factors.

Moisture can lead to issues such as mold and mildew growth, which can damage the surface and affect the application of composite materials. Direct sunlight can degrade the gel coat, causing fading and compromising its structural integrity over time. Dust accumulation can create imperfections in the surface, leading to defects in the final composite product. Paint spills or chemical exposure could also adversely affect the gel coat, potentially requiring repairs before the mold can be used again.

Variations in temperature, whether extreme heat or cold, can cause expansion and contraction in the gel coat material, which might lead to cracking or other forms of damage. Therefore, it is essential to protect the gel coat from moisture, direct sunlight, dust, paint spills, and extreme temperatures, making the comprehensive choice the most suitable protection strategy for preserving the mold during storage.
