Sheetrock Ultra Lightweight Joint Compound . I noticed it was aerated, which seemed odd given air bubbles are not a good thing. It hardens quickly (you guessed it, in 45 minutes), shrinks very little and dries hard as a rock. ProForm Ultra Lite 4.5Gallon Premixed Lightweight Drywall Joint from www.lowes.com Conventional compounds need three (sometimes four) coats to cover metal corner beads and fasteners. It also sands with the ease of a topping compound and bonds like a. Up to 25% less weight, less shrinkage and exceptional ease of sanding.
