Designed for professional drywall contractors, FibaFuse makes paper tape obsolete. The mold-resistant product is made with an open-web material that allows joint compound to bond with its reinforced glass fibers and the drywall. It results in a more durable joint that resists cracking and requires less mud during application. Cost: $3.70 to $5.00 per roll. Saint-Gobain Technical Fabrics. 800-762-6694.
