Setting Up and Applying Sandblasting
Last Updated: October 17, 2023 Sandblasting is a tried-and-true technique used to prepare metal substrates and various material surfaces prior to applying treatments, coatings, or other finishes. Whether your goal is to economically remove paint, smooth out burrs, clean surfaces, create a polished finish, strip off scales, perform shot peening, or achieve decorative etching and fine finishing, there’s a sandblasting application tailored to meet your needs.

A variety of components work harmoniously within an air abrasive blasting system to deliver efficiency and effectiveness. Here are the key parts of sandblasting equipment you need to know about: - Air compressors that supply the high-pressure air crucial to the sandblasting process. - A blast pot or pressure blast tank, which serves as a certified pressure vessel for feeding abrasives into the airflow. - Nozzles that direct abrasive media at the right angles to effectively sandblast surfaces. - Moisture traps and separators that remove water from compressed air before it enters the pressure blast tank. - Deadman switches that give the operator complete control, enabling them to stop the airflow and abrasives in case of a malfunction or safety issue. - Hoses ensuring smooth passage and control of air and abrasives throughout the system. - Abrasive blast materials chosen based on their type, size, shape, and hardness suitable for the specific application. - Blast respirators, also known as hoods, which are vital for safeguarding operators by offering comprehensive protection and supplying OSHA-approved clean air free from abrasives, dust, and contaminants.Tips for Setting Up Sandblasting Gear
As there are numerous types of sandblasting systems, setup procedures may vary. Below are general steps and considerations for setting up these systems: - Inspect all parts and components thoroughly before assembling them to detect cracks, leaks, or other damage or defects. - Position the compressor upwind from your workspace and on flat ground to prevent dust and debris from entering the system and ensure the oil and moisture separators and lubrication systems operate correctly. - Lay out the bull hose and blast hose as straight as possible to prevent kinks and reduce bends that could affect material flow and performance. - Carefully connect hoses and pin fittings, checking again to ensure everything is securely in place and free of air leaks. - After all hoses are connected, follow the manufacturer's recommended startup procedure. Once warmed up, verify the air pressure gauge is reading within the desired range, making adjustments if necessary before beginning the sandblasting process. - Perform a compressed air cleanliness test and nozzle pressure test to confirm the air is free of moisture and oil and that the pressure is optimal for the type of abrasives and surface material being used. - Always wear safety gear, including a blast hood, steel-reinforced boots, a heavy canvas-style blasting suit, and protective gloves during operation—available from Finishing Systems.Frequent Sandblasting Errors to Avoid
While sandblasting is highly effective, there are pitfalls to steer clear of for the best outcomes and experiences. To prevent costly mistakes and safety hazards, use proper equipment and safety gear.Overlooking Safety Measures
Failing to follow safety protocols can lead to serious injuries for you or those nearby. Always cover exposed skin when sandblasting. A full-face mask is ideal for facial protection, but safety glasses are mandatory at a minimum. Wear thick gloves and try to keep yourself and others out of the line of fire as much as possible to avoid accidents.Not Recycling Blasting Materials
A common oversight is letting blasting materials escape without attempting to gather them. While professional sandblasters utilize cabinets, a sheet or tarp works well for DIY projects. Collecting your materials allows you to reuse them, saving costs.Selecting Inappropriate Particles
Various particles can be used for blasting, with sand being the most common choice. However, choosing the wrong material for your task is easy. Consider whether the particle's hardness suits the job. For instance, glass beads are preferable to sand for blasting tiles since they're smoother and finer, preventing damage to the tile.Seek Expert Guidance on Sandblasting Equipment and Setup
