Abstract
A joint compound or wall repair composition and the method of making the same is disclosed that reduces the amount of airborne dust emitted during traditional sanding processes. Generally, such a reduction can be achieved by combining a first binder that has a high glass transition temperature and a second binder that has a low glass transition temperature with conventional joint compound compositions.
