Fiberglass Tape. FibaFuse paperless drywall tape by Saint-Gobain Technical Fabrics is composed of a porous fiberglass that makes it highly mold resistant and stronger than paper tape, says the manufacturer. Although designed as a complement to paperless and mold-resistant drywall for moisture-prone installations, it’s suitable for joints on all types of drywall. It can be used in mechanical and automatic taping tools and allegedly requires less mud and resists blistering and bubbling better than paper tape. A 250-foot roll costs about $4.
