Stop water infiltration through exterior cracks up to 1/8" in mortar joints on chimneys, brick, or stone walls with fireplace sealant. Brush on with special included brush. One-half gallon of Chimney Saver crack and joint sealant treats an average of 550 standard-sized bricks.
(Note: Leaves a slight gloss on most dense surfaces. Build up of this exterior chimney sealant can leave a cloudy appearance).
