Our methods for matching original texture, color and finish are well thought out. In most cases with aged stone, we’re confronted with varying color and texture of both unit and joint. When and where the stone is quarried, exposure and climate are just a few of the factors that play a significant role in appearance. To achieve the best results with so many variables in texture and density, we prefer field mixing to match all mortars from scratch.
Brick joints also vary in color and texture. Different types of bricks will have different mineral and manufacturing origins. Terms like IRA (initial rate of absorption) and waterstruck are terms that refer to how they’re manufactured and how they’ll respond to the weather/time based upon their makeup. These factors along with exposure, climate, age and original mortar composition determine what type of finish or texture the mortar will have with age. We achieve very positive results in durability and aesthetics by cutting the joint deep for a better bond, packing the mortar fully into clean and damp joints, properly striking the joint at the right time and finishing much later with a sponge and water. The sponge technique not only keeps the mortar damp during the curing process but in combination with acid washing it will reveal the sand grains in the brick joint mimicking the old style.
