Is Tarred Bankline Resistant to Molds and Mildew?

Characteristics of Tar

Tar is a sticky, viscous liquid obtained from wood tar, petroleum, or plant-based sources. It is often used to treat cordage, such as bankline, to protect it from moisture, UV light, and microbial growth. The phenolic compounds present in tar have been shown to inhibit the growth of various fungi and bacteria.

Resistance to Molds and Mildew

The tar content in bankline can provide a level of resistance to molds and mildew, especially in a marine environment where moisture levels are high. However, the degree of resistance depends on several factors, including the type and quality of tar used, the thickness of the tar coating, and the storage and handling conditions of the bankline. As a general rule, a tar coating of 10-20% by weight can provide adequate protection against molds and mildew.

Factors Affecting Resistance

While tarred bankline can resist molds and mildew to some extent, it is not completely immune to microbial growth. Factors such as temperature, humidity, and exposure to sunlight can all affect the tar’s ability to resist microbial growth. In addition, if the tar coating is damaged or worn off, the underlying bankline may become susceptible to molds and mildew. As a result, it is essential to regularly inspect and maintain tarred bankline to ensure its continued integrity and resistance to microbial growth.
