The CertainTeed Marco Spark-Perf drywall joint tape is manufactured from a special fibered-paper with added tensile strength to help prevent tearing, wrinkling or stretching. It's designed for use with all quality joint and taping compounds to reinforce gypsum board joints and corners before painting, texturing or wallpapering. The Spark-Perf perforations allow for smooth installation without the risk of air bubbles or blisters settling in. It is already centre-creased for increased installation accuracy, and roughed on both sides for durable holding and bonding power. This product comes in a 75-foot roll and 2 1/16-inch width.
