New Masonry Cleaning
This photo shows how poor CMU block can appear with extensive lime run including rust streaks on colored, burnished block. Bielski can remove the lime run, rust stains while leaving the color, texture and grout intact.
Lime streaks occur primarily during new construction when CMU grout cells are exposed to inclement weather cycles. This weather pattern dissolves the free lime in the mortar, as days pass the CMU wall dries at the surface, the free lime then migrates to the surface of the CMU block and forms crystalline lime run.
