Easi-Fil All-Purpose Drywall Compound is a pre-mixed all-purpose joint compound that's great for embedding wallboard tape, filling and finishing joints, and hiding trims and fasteners. Easy-to-use right out of the package, its off-white colour makes this compound ideal for all types of drywall projects. Each container is filled with 4.5 L of product that's easy to spread, sand, and stack in by-the-litre pails. You'll need approximately 1.25 L of drywall compound to cover a 4-ft x 8-ft sheet of drywall. Easi-Fil has a shelf life of 12 months from the production code date when stored properly.
