Best mediums for sandblasting

Ready to kickstart your sandblasting project but unsure which materials to use? Let’s walk through some great options, including but not limited to our top quality silica sand:

Sandblasting Sand

Sand is a medium of choice for sandblasting. It’s an affordable, effective and eco-friendly, making it one of the most popular options for sandblasting. We at GuyTec Industries offer three types of low-dust sandblasting sand that will make your sandblasting job a breeze:

Silica Sand #2 (80/100 mesh)

Silica Sand #2 (80/100 mesh) – the finer touch in the world of sandblasting! This specific mesh size is super handy for delicate tasks where you need precision without too much surface disruption. It’s perfect for giving surfaces a gentle yet thorough clean, especially when you’re prepping for a final finish or paint.

Silica Sand #4 (50/80 mesh)

Silica Sand #4 (50/80 mesh) really steps up when you need a balance between fineness and aggressiveness in your sandblasting tasks. It’s coarser than the 80/100 mesh but still fine enough to handle more delicate jobs that require a bit more oomph. This makes it ideal for intermediate cleaning tasks, where you need to remove impurities without going too deep into the surface.

Silica Sand #7 (30/50 mesh)

Silica Sand #7 (30/50 mesh) is a coarser option, perfect for more robust sandblasting tasks that require stronger abrasive action. Ideal for stripping tougher paints or smoothing out rough surfaces, this sand can really tackle those harder-to-clean areas without being too harsh.

Glass Beads

Glass beads are ideal for delicate, non-aggressive cleaning and polishing, ensuring a smooth finish without removing too much surface. They’re less eco-friendly due to their production process but are recyclable, which can mitigate environmental impact somewhat. They may not handle tough grime well and tend to be pricier than more abrasive options.

Aluminum Oxide

Aluminum oxide is tough and ideal for heavy-duty tasks like etching or removing tough coatings. It’s not the most eco-friendly due to its synthetic nature but offers durability that can lead to less frequent replacements. It is however not suited for delicate surfaces and is more expensive than simpler abrasives.

Steel Grit

Steel grit is highly effective for stripping heavy coatings and preparing surfaces for repainting. However, its aggressiveness might damage softer materials. It’s also less eco-friendly as it can contribute to high metal waste and is not biodegradable.

Walnut Shells

Walnut shells are an environmentally friendly abrasive, perfect for light cleaning and polishing. They are biodegradable and gentle on surfaces but lack the power for more demanding rust or paint removal tasks.

Plastic Abrasives

Plastic abrasives are useful for sensitive surface work but are not eco-friendly due to their non-biodegradable nature. They can be recycled, which helps reduce their environmental footprint. Ideal for tasks requiring surface preservation, though they come at a higher cost.

Mitigating health risks

Sandblasting, while effective for surface preparation, introduces significant health hazards primarily due to the inhalation of dust particles, which can cause severe respiratory problems and other health issues. Here are some detailed measures that we strongly recommend to mitigate these risks. Adhering to these guidelines can significantly reduce health risks associated with sandblasting, ensuring a safer working environment.

  • Wear Protective Gear: Essential personal protective equipment includes respirators approved for fine particulates, safety goggles, gloves, and durable coveralls.
  • Ensure Proper Ventilation: Implementing exhaust systems and using containment methods such as blast cabinets can help control the spread of dust.
  • Regular Health Monitoring: Workers should undergo regular health checks to detect any early signs of respiratory distress or other health issues related to dust exposure.
  • Training and Safety Protocols: Conduct thorough training sessions for all operators to understand the risks and the correct use of equipment and safety measures.
  • Equipment Maintenance: Regularly check and maintain sandblasting equipment to ensure it is sealing and functioning properly to minimize leaks and dust escape.
