Abstract
Abstract A sprayable composition for use as a sealant or coating for various surfaces, especially concrete block walls, is disclosed which includes water soluble silicate, water, cellulose fibers, clay and limestone. The cellulose fibers enable the sealant to have a sprayable consistency and good thixotropy when the sealant composition is sprayed on a vertical surface or a ceiling. A method of using the sealant composition also is disclosed.
