CertainTeed’s MARCO® SPARK-PERF® Paper Tape is made from a special high-fiber paper with added tensile strength to prevent tearing, wrinkling, and stretching. This high-performance product ensures superior adhesion, ease of use, and long-lasting crack resistance. Designed to provide excellent adhesion with joint compounds, its unique spark perforations prevent air bubbles from forming underneath the tape while maintaining high-quality strength. The center crease is precision-made, making it easier to construct straight, crisp lines for inner corners, and its precisely roughened surface creates excellent adhesion. Optimized at 2-1/16 inches wide, MARCO SPARK-PERF Paper Tape offers an excellent solution for achieving a professional and durable finish on drywall projects. With MARCO SPARK-PERF Paper Tape, you can be confident that your drywall project will look its best and provide the fire protection and durability needed for years to come.
