ABSTRACT:
In a bucket, partially filled with an aqueous slurry of drywall joint compound, the joint compound is hermetically sealed from the air above by a formed-in-place flexible solid seal disposed over the entire top of the joint compound and preferably extending a short distance up the inner wall of the bucket. For partial use of the joint compound, the seal is first separated from the bucket inner wall and then lifted off the joint compound, cleaned, and kept in a condition suitable for reuse.
