Much like the ability to create a perfect masonry wall, achieving the perfect mortar color match is an artform. Matching different types of mortar is necessary any time you do a repair or addition to brick and masonry. By properly matching the mortar ensures that the new construction blends in with the older construction, thus providing a uniform appearance. Matching the type of mortar can require a bit of trial and error to determine the type of sand that was used. Matching the color of the mortar is a little more difficult as mortar changes colors when exposed to sunlight and other outdoor elements. We at Gergs pride ourselves in our expert color matching mortar applications.
