improper repairs and moss growth

Some damaged areas were caused by water runoff from the roof. These areas were recognized and improved by repairing gutters or installing new and/or downspouts prior to the restoration of the stucco. The original stucco consisted of a mix of Portland cement and coarse sand dating back to the late 1900. The mortar chosen for this restoration was a NHL 3.5 with coarse sand matching the original in size. The reason for choosing a natural hydraulic lime instead of a Portland cement was made because the original Portland cement no longer corresponds in compressive strength and modulus of elasticity to the Portland cement currently produced today. When a restoration is to be performed correctly, the choice of restoration material should always be as close as possible to the original, or slightly on the "softer" side.
