High-tack BlastLite™ is a specially-formulated rubber mask that is long-lasting and easy to use. This specially formulated rubber allows the material to conform tightly around curves and uneven surfaces. Natural flexibility properties and impact resistance makes it ideal for all substrates where shallow blasting is required. BlastLite™ High-tack Stencils are coated with an acrylic adhesive for use on raw wood, unprimed HDU, brick or unglazed tile. Available unpunched or friction fed. Can also be cut by a knife for a more precise fit.
