EASY Skim Coat Application

What happens here

Prepare the skim coat material by mixing water-resistant gypsum powder (Boero brand) with water. Pour the dry powder into clean buckets and add water gradually while mixing with a drill mixer until a smooth, lump-free, and consistent paste is formed. This product is beneficial because it's fast-drying (1.5-2 hours with a fan), easy to sand, non-shrinking, and can be used both indoors and outdoors. After the initial mix, let the material rest for 5 minutes, then mix it again to achieve optimal consistency for application.
