381630 DuraBond® 90 Setting‑Type Joint Compound – 25 lb Bag

The DuraBond® 90 Setting‑Type Joint Compound is a high‑strength, professional drywall compound engineered for maximum durability, excellent build‑up capability, and extended working time. Designed for demanding repair and finishing applications, this compound offers an approximate 90‑minute working time, providing ample flexibility for larger jobs, detailed repairs, and multi‑step finishing processes.

Unlike lightweight or easy‑sand setting compounds, DuraBond® 90 is formulated for exceptional hardness and impact resistance once set. It sets chemically rather than air‑drying, allowing it to harden reliably regardless of humidity or temperature conditions. After setting, it creates an extremely dense, solid surface that resists cracking, denting, and shrinkage—even in high‑traffic or high‑stress environments.

While DuraBond® 90 is not designed for easy sanding, its superior strength makes it ideal for base coats, deep fills, and repairs where long‑term durability is critical. It is commonly used before finishing coats of ready‑mix or easy‑sand compounds, or in areas requiring reinforced repairs.
