Methods for Cleaning Metal Surfaces

In industrial construction, cleaning metal surfaces is extremely important, directly affecting the adhesion, quality, and durability of coatings. Choosing the right cleaning method not only improves work efficiency but also saves a lot of time and costs. Here are the most commonly used methods today:

1. Cleaning with a Wire Brush or Mechanical Grinding

This is a manual method, using a wire brush or a grinder to remove surface rust. It’s simple and easy to do but not highly effective. It doesn’t completely remove contaminants and doesn’t create the proper surface roughness, making it hard for paint to stick and easy for coatings to peel off over time.

2. Cleaning with Chemical Solvents

This method uses special chemicals to clean dust and grease from metal surfaces. It’s suitable for delicate surfaces that can’t be treated mechanically. However, it can’t remove heavy rust or old paint layers, and it requires strict chemical safety procedures.

3. High-Pressure Water Blasting

This method uses water at pressures between 1,700–2,000 bar. It’s environmentally friendly and doesn’t create dust. However, for heavily rusted surfaces or surfaces that need roughness for better paint adhesion, high-pressure water blasting is not effective enough to do a thorough job.

4. Wet Sandblasting

This is a combination of abrasives and water, helping to reduce dust during the cleaning process while still removing surface dirt. The biggest drawback is that after cleaning, the surface must be dried immediately; otherwise, it can quickly rust again due to high moisture, especially in humid climates or near the ocean.

5. Dry Sandblasting with Garnet Abrasives – The Best Solution Today

Dry sandblasting using Garnet abrasives is the most advanced and effective method for cleaning metal surfaces. Under high pressure, Garnet abrasives can:

+ Quickly remove rust, grease, and old paint

+ Create the perfect surface roughness for excellent paint adhesion and longer-lasting coatings

+ Shorten construction time and keep projects on schedule

+ Reduce maintenance costs thanks to Garnet’s ability to be reused multiple times

+ Be environmentally friendly, low-dust, non-toxic, and safe for workers

With its high hardness and sharp edges, Garnet provides superior cleaning performance, making it ideal for high-standard surfaces like steel structures, storage tanks, pipelines, ships, and especially in the oil, gas, and chemical industries.

Each cleaning method has its own advantages but also certain limitations. Among them, dry sandblasting with Garnet abrasives not only stands out for its excellent cleaning ability but also offers the best balance of cost, time, and safety.

Nếu If you are working in industries with strict standards like oil and gas, shipbuilding, or steel structures, Garnet abrasives are the most reliable choice today. Make sure your surfaces are properly prepared from the very first step by choosing high-quality abrasives from a trusted supplier.
