What are the effects of sandblasting on polyethylene bench surfaces?

Sandblasting is a popular surface treatment method used to clean, smooth, or roughen materials, including polyethylene benches. When applied to polyethylene surfaces, sandblasting can significantly alter their texture and appearance. The high-pressure abrasion removes surface contaminants and creates a matte finish, which can enhance grip and reduce slipperiness. However, excessive sandblasting may lead to micro-cracks or thinning of the material, potentially compromising durability over time.

Polyethylene is known for its resistance to moisture and chemicals, but sandblasting can expose fresh layers of the material, making it more susceptible to UV degradation if not properly treated afterward. For outdoor benches, this could shorten lifespan unless protective coatings are applied post-treatment.

On the plus side, sandblasting can restore weathered polyethylene benches by removing oxidation and stains, giving them a renewed look. It’s also an efficient way to prepare surfaces for painting or adhesion treatments.

In summary, sandblasting offers both benefits and drawbacks for polyethylene bench surfaces. Proper technique and post-treatment care are essential to maximize longevity and performance.
