EASY Skim Coat Application

What happens here

Pour the Boero water-resistant gypsum powder into a clean 5-gallon bucket. Gradually add water while continuously mixing with a powerful drill fitted with a paddle mixer. Mix until the compound reaches a smooth, lump-free, and consistent paste-like form, similar to a thick milkshake or heavy pancake batter. Once mixed, let the compound rest for approximately 5 minutes to allow the water to fully penetrate the powder. After resting, mix it once more to ensure uniform consistency before application. This product is beneficial because it's water-resistant, dries quickly (1.5-2 hours with a fan), and sands easily without shrinking.

Goal: Prepare the skim coat compound by mixing water-resistant gypsum powder with water using a drill and paddle mixer until a smooth, consistent, paste-like texture is achieved. Allow it to rest, then mix again.
