Care During Installation

During installation care must be given to mask and protect the stone already set All mortar droppings adhering to the stone should be removed immediately. All tape should be removed as soon as work is completed in the area to prevent any
marking from tape adhesive.

Sponge the stone free of mortar along the joints as work progresses. After completing the mortar and tuck-pointing process, stone should be cleaned of all
stains and foreign matter by using a stiff fiber brush, water, mild soap, and final flushing with clear water.
Note: the brush can dull the surface of honed or polished stone depending upon the pressure applied.

General Cleaning Methods

  1. Thoroughly wet area with clean potable water, then sponge clean.
  2. Wet the area with clear water. Using a mild detergent, potable water, and a sponge, gently clean the stone. Thoroughly rinse with clean water before the detergent dries.
  3. Using a standard garden hose with a typical nozzle and normal tap pressure, wash the area.

Never use cleaners that contain acids on limestone, it can dull, discolor, etch and leave streaks on the finish of the stone. Be cautious of common household cleaners, common foods and drinks (such as alcohol or citrus juices) which can contain acids.
