Grit blasting is a core surface preparation service offered by Polaris Marine Group to support the construction and maintenance of marine infrastructure. Using hard, angular abrasives such as steel grit, this method is highly effective in removing heavy corrosion, old coatings, and stubborn marine growth.
It is particularly useful on steel and concrete surfaces that require a deep clean before repainting or structural repairs. In the harsh conditions of coastal environments, grit blasting provides the strength and accuracy needed to restore marine assets and prepare them for long-lasting protection.
Sand blasting, also known as abrasive blasting, is a powerful technique we use to remove old coatings, surface contaminants, and corrosion, allowing marine assets to be properly restored and protected.
Surface Preparation for Marine Durability
Unlike sand blasting, which typically uses softer media, grit blasting uses coarse, aggressive materials to etch a profile into the surface. This textured finish is ideal for bonding primers and industrial-grade marine coatings. At Polaris Marine Group, our team uses grit blasting to treat everything from barge hulls and steel pilings to sheet piling walls, wharf structures, and other key marine assets. The result is a clean, profiled surface that is ready for high-performance finishes that resist salt, moisture, and impact.
Applications Across Marine Structures
Polaris Marine Group integrates grit blasting into a wide range of projects. This includes preparing underwater piles for wrapping or epoxy coating, cleaning corroded vessel hulls, and removing flaking paint from ageing steel structures. The process helps reveal the true state of the asset, uncovering hidden defects or corrosion that might otherwise go unnoticed. With this visibility, our team can recommend repair strategies or coating solutions that extend the working life of critical marine infrastructure.
Our grit blasting services are also widely used on commercial vessels, pontoons, and floating equipment. Regular maintenance using this method helps reduce drag, improve fuel efficiency, and keep vessels looking and operating at their best. Whether it’s part of a dry-docking process or a targeted surface treatment, Polaris Marine Group provides precise, reliable blasting outcomes that support both performance and appearance.
Environmentally Responsible Blasting
At Polaris Marine Group, safety and environmental care are essential to every grit blasting project. The abrasive process generates dust and debris that must be managed responsibly, especially when operating near water. Our team uses containment systems, waste collection, and filtration methods to prevent contamination. We follow strict environmental regulations and ensure our projects are compliant with EPA guidelines and industry standards.
Mobile and Flexible Solutions
We understand that marine works don’t always happen in one place. That’s why Polaris Marine Group offers mobile grit blasting units that can be deployed to remote coastal locations, shipyards, or urban port facilities.
Our flexible approach allows us to support scheduled works, emergency repairs, or ongoing maintenance programs with the same high level of care and technical detail. We work efficiently and professionally to minimise downtime while ensuring a quality result.
