ALLTEK delivers a superior surface finish

ALLTEK’s garnet grains clean deep into cavities and pitted areas down to bare metal, removing all rust, soluble salts and other contaminants for a surface that is virtually free of embedments, rogue peaks, and troughs. ALLTEK garnet blasting abrasives improve coating adhesion and coating life by producing a clean substrate with a uniform surface profile

ALLTEK can be used on a variety of substrates

ALLTEK is ideal for use on steel, aluminum and other sensitive substrates.

ALLTEK low dusting offers better visibility and safety

BARTON garnet is a 100% natural, nonferrous inert mineral with <0.1% respirable crystalline silica and no heavy metals. It produces less dust than many other blasting abrasives, resulting in improved visibility, less disruption to adjoining work areas, and safer working conditions. ALLTEK alluvial garnet poses little or no health or environmental risks.

ALLTEK is available in a variety of grades

You can select from two (2) Grades of ALLTEK alluvial garnet blasting abrasives. Both are manufactured under tight QC/QA controls and guaranteed to meet BARTON’s high standards.

BARTON garnet blasting abrasives also meet all the current industry standard, including U.S. Navy MIL-A-22262B(SH), SSPC-AB 1(Type 1, Class A), QPL Listed and CARB certified.

30/60 PLUS — Intermediate

A workhorse grade used for new steel and maintenance work on coatings up to 20 mils. Typically produces a 2.5-3.5 mil profile on steel.*

80 HPA — Medium

Ideal for steel, aluminum and other sensitive substrates. The preferred abrasive for most vapor-blasting applications. Typically produces a 2.0-2.8 mil profile on steel.*

Standard Packaging: 55-lb. paper bags, 2,200-lb. and 4,400-lb. bulk bags.

ALLTEK alluvial garnet is part of BARTON’s comprehensive, best-in-class line of waterjet cutting and blasting abrasives.

*Profile ranges cited are typical for dry-blasting applications at usual pressures (90-100 PSI). The substrate, air pressure and other factors will impact the actual profile achieved. The proper grade of BARTON garnet abrasive for a project is best selected based on test results conducted under actual field conditions.
