Reliable and Long-lasting Sealant for PVC fabric.

[For Polypropylene (PP) and Polyethylene (PE) fabric use Global Tarp Seal]

GLO-MASTIC is a solvent free acrylic all-purpose elastomeric membrane system designed to provide a continuous watertight or gas-tight seal in situations where considerable structural movement of the substrate may be anticipated.

The excellent waterproofing and durability characteristics of this product make it an ideal choice for sealing tarp seams and silos for long life performance through a wide range of climatic and environmental conditions.

Grain tarps and silos must be sealed for effective fumigation. View our silo sealing brochure here. Silo Sealing Brochure.
