AL420-30-KIT-B | Complete Wet Sandblast Kit Rust & Paint Removal

The AR North America AL420-30-KIT-B Sandblast Kit is a complete, professional-grade wet sandblasting
system that transforms a standard pressure washer into a high-performance surface restoration tool. By combining
pressurized water with abrasive media in a controlled stream, it delivers deep cleaning power for removing rust,
paint, scale, corrosion, and tough coatings from metal, concrete, stone, and machinery—while dramatically reducing
airborne dust compared to dry blasting.

How the Wet Sandblast Process Works

Venturi-Style Mixing Head

A venturi-style sandblast head mounts to the pressure washer wand and uses the high-velocity water stream to draw
abrasive media through the suction hose. Water and media blend in the nozzle, producing a powerful, even blast that
strips contaminants quickly without gouging or overheating the base material.

Water-Assisted Blasting Advantages

• Reduced dust: water captures airborne particles for a safer, cleaner work area.
• Cooler surface temps: minimizes heat buildup that can warp or pit sensitive substrates.
• Uniform coverage: consistent media flow promotes even cleaning and predictable surface profile.

Key Features & Specifications

• Professional wet sandblasting kit: converts most pressure washers into abrasive blasters.
• Operating range: typically 3,000–5,000 PSI with 3–5 GPM water flow.
• Venturi nozzle assembly: draws abrasive via suction for smooth, controlled media delivery.
• 30-foot suction hose: flexible reach to media containers without constant repositioning.
• High-pressure coupling: secure, leak-resistant connection to compatible wands and lances.
• Corrosion-resistant construction: components built to endure water, abrasives, and pressure.

Setup & Operation

Basic Connection Steps

• Attach the sandblast head securely to the pressure washer wand or lance.
• Place the 30-foot suction hose into a container filled with suitable abrasive media
  (silica-free sand, garnet, baking soda, or other compatible blast media).
• Connect the high-pressure hose from the pressure washer to the blast head using the supplied coupling.
• Start the pressure washer and verify that abrasive is being drawn consistently into the water stream.

Operating Tips

• Adjust working distance and wand angle to fine-tune aggressiveness for different materials.
• Use lower stand-off and slower travel for heavy rust and coatings; increase distance for more delicate surfaces.
• Test on a small, inconspicuous area to confirm finish before treating large sections.

Typical Applications

• Removing rust, paint, and scale from vehicle frames, trailers, and heavy equipment.
• Stripping old coatings from concrete pads, steel structures, railings, and tanks.
• Cleaning marine hulls and metal hardware while minimizing dust and rebound.
• Restoring weathered tools, castings, and architectural metalwork.
• Surface preparation before painting, coating, or welding where a clean profile is critical.

The wet blasting action efficiently removes contaminants while preserving the integrity of the underlying material,
making it a preferred method for maintenance professionals, contractors, and restoration specialists.

Maintenance & Care

Post-Use Cleaning

• After each job, flush the nozzle and suction hose thoroughly with clean water to clear residual abrasive.
• Inspect the nozzle tip, fittings, and hose for wear, especially when using coarse media.
• Replace worn or damaged components promptly to maintain consistent performance and safety.

Storage

• Allow components to dry completely before storage.
• Store the kit in a clean, dry location away from direct sunlight and chemicals to prevent hose deterioration and corrosion.

Compatibility & Value

Fully compatible with AR North America pressure washer systems and most professional-grade washers in
the appropriate PSI/GPM range, the AL420-30-KIT-B offers a ready-to-use wet abrasive blasting solution.
Its durable construction, predictable venturi feed, and reduced-dust operation make it a dependable choice for surface
preparation, equipment restoration, and industrial maintenance where clean, consistent results matter.
