About products and suppliers

A sandblaster is a powerful device used to shape, smooth, or clean surfaces using sand or other abrasive materials propelled at high speeds. The main feature of a sandblaster is its ability to forcibly eject surface contaminants (e.g., rust, old paint) to unveil a clean, fresh surface underneath. These versatile tools can be used in everything from industrial manufacturing processes to small-scale art and craft projects.

What is a sandblaster used for?

Sandblasters are often used for grit blasting, where hard, granular materials are used instead of sand to agitate surfaces. Sandblasting wood is another common application, where sandblasters are used to craft unique designs into wooden surfaces or restore old furniture by effectively removing paint or finish. Abrasive blasting or sandblasting, the blanket terms for this process, can prepare surfaces for painting, remove rust or scale, or provide texture to smooth surfaces.

Types of sandblasters and their features

Gravity-fed sandblasters operate by using gravity to feed the sand into the blasting gun. They're a great choice for smaller projects due to their simplicity, reduced cost, and ease of use. Pressure-fed sandblasters store abrasive material in a pressurized reservoir rather than relying on gravity. They are often used in professional or industrial environments, as they operate continuously and more powerfully. Siphon-feed sandblasters suck the abrasive material through a siphon tube and out the blast gun, and they are typically used for small household projects due to their affordability and ease of operation.

Features of sandblasters can vary significantly depending on the type. For instance, a portable sandblaster features a carryable, often wheeled design for increased mobility and ease of use. Pressure washer sandblasters combine the power-cleaning performance of a pressure washer with the surface preparation capabilities of a sandblaster. A small sandblaster is lightweight and easy to manage, perfect for home use or smaller projects. An industrial sandblaster is designed with larger, more complex tasks in mind and often features higher power output and a larger media capacity. A hand-held sandblaster offers maximum portability for spot cleaning and small tasks.

Why is sandblasting so effective?

Sandblasting is highly effective because it uses high-speed projectiles to aggressively scour surfaces. This efficient process can clean and prepare surfaces more quickly and thoroughly than manual scraping or sanding could achieve. Besides, it can effectively reach tiny nooks and crevices that might otherwise be hard to clean.
