Contrasting Mortar Art Wall
On a non-structural brick garden wall, selectively remove 1-inch-deep mortar in a geometric pattern (chevrons, diamonds, or waves) using the 4-inch segmented blade. Refill those joints with a contrasting, pigment-tinted mortar to create a durable, weatherproof mural that reads from the street. Mask off adjacent bricks, work in sections, then seal for color pop.
Salvaged Brick Planter Build
Use the blade to clean old mortar off reclaimed bricks, preserving the patina while making them stack-ready. Dry-fit a stepped planter or raised herb bed, then lay with a lime-based mortar that matches the vintage look. Cap with cleaned soldier-course bricks for a crisp top edge.
Patio Pattern Refresh
On a tired brick patio, remove weathered joints along selected courses to create stripes or borders. Repoint those joints with colored mortar or polymeric joint compound to introduce subtle patterns (charcoal border, terracotta field) without lifting the field bricks. Finish with a breathable sealer.
Inset House Numbers in Mortar
Cut shallow channels in vertical and horizontal mortar joints to create a rectangular recess for metal address numbers or a plaque. The 1-inch cutting depth lets you inset the hardware flush to the wall without cutting bricks. Rebed the plaque in fresh mortar, achieving a clean, integrated look.
Brick Coffee Table Top
Harvest thin faces from damaged bricks by freeing them from old mortar joints, then arrange the faces in a wood frame to form a table top. Grout with a contrasting mortar; the segmented blade helps clear and square edges for tight seams. Finish with a matte seal to resist rings and spills.
