Licensed Blastox® Blender

Blastox® is a patented granular, complex calcium silicate-based blasting abrasive additive.

Use: Typically used at a 15 percent weight ratio for stabilizing lead in lead-based paint blast removal operations, producing a non-hazardous waste suitable for disposal in a local subtitle D landfill. Use is compatible with standard dry or wet blast equipment.

Chemical Reactions: Blastox® produces lead silicates through chemical conversion pH adjustment and physical encapsulation of the lead in the paint. It is intended solely as a lead stabilizing additive, rendering the waste non-hazardous according to TCLP criteria.

Restrictions: Material must be kept dry until preparations are made for field application. Wet or otherwise contaminated Blastox® does not carry a performance guarantee. For dry blasting operations, moisture separators are required and air dryers are recommended. Blastox® is designed with cementitious properties and may solidify in equipment, on substrates and around general work areas upon extended exposure to moisture. Care should be taken to avoid these situations or additional cleaning measures may be required.

Application Techniques: For dry blasting lead painted steel, six (6) to eight (8) pounds of a 15 percent weight ratio blended abrasive must be used per square foot of paint removed for adequate stabilization. For blasting lead painted wood substrates or for blast operations using less than six (6) pounds per square foot of paint removed, contact TDJ Group's Technical Service for specific recommendations.
