What is the best and safest material to use on refacing an interior brick chimney behind my free standing woodstove? Plaster, cement, stucco...what? The chimney comes out 13" from the back brick wall, which extends 8" on each side. The face of the chimney is 16" across. The chimney extends 8' up from the base of the tile floor to the ceiling. We want to cover the ugly brick and make it contrast with the new tile floor. Thanks.
