What is Sand Blasting?

Sand Blasting, also known as sandblasting or abrasive blasting, is a process of applying high pressure to push solid particles across the object surface at high speed to alter the surface roughness. The machine to complete the sandblasting operation is the sandblaster, which shoots a stream of abrasive material by a centrifugal wheel or pressurized fluid like compressed air and propelling it through the area need to be treated. The materials can be sandblasted, including aluminum, brass, silver, wood, stone, glass, and other metals.

How Does Sand Blasting Work?

A sandblasting system is basically composed of the air source, sandblasting cabinet, the dust collector, and the blasting media. The abrasive material used in sandblasting is referred to as blast media, typically including silica sand, garnet, crushed nut shells or fruit kernels, corn starch, wheat starch, sodium bicarbonate, dry ice, steel shot, steel grit, stainless steel shot, cut wire, copper shot, zinc shot, process byproducts, etc. The air source is usually a bottle of gas or an air compressor, the sandblasting cabinet is used to hold the product being blasted, and the dust collector clears off dust from the cabinet.

The process of sandblasting can be simplified as: open door -> put object to be blasted -> close door -> turn on the power -> wear gloves -> grab the blast gun and step on the foot pedal -> sandblasting the surface -> blow-off item with nozzle -> check if the product is blasted as required -> repeat blasting process if any zone needs -> open door -> take off the object.

Advantages of Sandblast Service

Efficient cleaning: Sandblasting quickly removes dirt, rust, paint, oxidation, and other stubborn deposits from hard surfaces, making it much faster than manual cleaning methods.
Versatility in materials: The process works on a wide range of surfaces, from metals to glass and plastics, making it highly adaptable across industries.
Surface texturing: It can produce specific surface finishes and textures, improving aesthetics or enhancing functionality based on the application.

Preparation for further processes:Sandblasting is ideal for preparing parts for adhesion, bonding, insert molding, coating, or painting, ensuring better adhesion and durability.
Deburring and edge profiling: It helps eliminate burrs, smooth sharp edges, and refine die-cast components, improving both safety and product quality.

Common Sandblasting Methods for Metal Restoration

1. Traditional Sandblasting (Mechanical)

High-speed silica or quartz particles are blasted onto metal to remove rust and paint. It’s versatile but largely phased out due to the health risks of silica dust.

2. Wet Blasting

Water is mixed with abrasive media and sprayed to reduce dust and heat. It’s ideal for delicate surfaces needing clean finishes with minimal airborne particles.

3. Vacuum Blasting (Dustless Blasting)

A vacuum system recovers both abrasive and debris during blasting, making it cleaner and reusable, great for confined or environmentally sensitive areas.

4. Centrifugal Blasting (Wheel Blasting)

Uses a motor-driven wheel to throw abrasives without compressed air, delivering a uniform finish for high-volume industrial cleaning jobs.

5. Soda Blasting

Uses baking soda with compressed air to gently clean softer surfaces like plastic or chrome, providing a smooth finish without damaging the base material.

FAQ

1. Types of metals and materials suitable for sandblasting

Glass
Stone
Metal (such as steel, copper, brass, aluminum, silver, etc.)
Wood
Plastic and Composite Materials (like PVC or plastic steel)
Brass
Aluminum
Silver

2. Will rust come back after sandblasting?

Yes, rust can return after sandblasting if the metal is left unprotected. Sandblasting removes existing rust and prepares the surface, but if not immediately coated with a primer, paint, or protective sealant, the exposed metal will begin to oxidize and rust again—sometimes within hours in humid conditions.

3. What is the average cost of sandblasting?

On average, sandblasting costs $2 to $5 per square foot, depending on the material, surface condition, and location. For a 1,500 sq ft area, most homeowners spend between $3,000 and $7,500. Hourly labor rates typically range from $45 to $75 per hour. Dustless blasting can be slightly more expensive due to equipment and material costs but offers cleaner results.

4. What is a cheap alternative to sandblasting?

Cheaper alternatives to sandblasting include:
Wire brushing (manual or with a drill attachment)
Chemical rust removers or paint strippers
Power washing or pressure washing with abrasive additives
Soda blasting kits (less abrasive and DIY-friendly)
These methods are more accessible for small projects and cost-effective for home use, though less powerful than professional sandblasting.

5. What are the rules for sandblasting?

Sandblasting must follow strict safety regulations and best practices, including:
Personal Protective Equipment (PPE): Use blast helmets, gloves, coveralls, and respiratory protection.
Ventilation & Dust Control: Operate in well-ventilated areas; use dust collectors or containment systems.
Safety Management System: Have written safety procedures, equipment checks, and operator training.
Abrasive Handling & Disposal: Store abrasives properly and dispose of used materials according to local regulations.
Emergency Preparedness: Ensure first aid kits, eyewash stations, and emergency plans are in place.
Ongoing Training: Keep workers informed and updated on safe handling procedures.

6. Can I do my own sandblasting?

Yes, DIY sandblasting is possible, but it requires caution and the right equipment. Some DIYers build simple systems using air compressors, bottles, or tanks—like in homemade setups using a coke bottle and air gun with a wood enclosure to contain dust. However, professional-grade results require proper safety gear, adequate air pressure, and knowledge of abrasive types. DIY sandblasting is best for small or non-critical projects; for larger jobs, professional services are recommended for safety and effectiveness.
