Upon delivery, all cast stone should be checked for chips, cracks, stains or broken pieces.
Storage of cast stone should be above the ground on non-staining planks or pallets. The storage site should be away from heavy construction traffic. Cast stone stored for an extended period of time should be kept on pallets or non-staining planking and covered with non-staining tarpaulins; be sure to allow for air circulation.
Cast stone should be handled in a way to minimize chipping. Care must be taken to not bump the stone into anything. Handle stones with the wide portion of the cross section in the vertical position to minimize breakage. After setting, columns, pilasters, entry jambs, window sills and all stone with projecting profiles should be protected during the remaining construction.
Prior to setting, insure climatic conditions are within thermal limitations of the mortar. Cold weather setting practices are basically the same as the International Masonry Industry All Weather Council (IMIAC) recommends for unit masonry. Mortar retarders and accelerators should be used according to the manufacturer's directions, but not with patching material. Set stone in full mortar joints and fill all dowel holes and anchor slots completely with mortar. Be sure uniform joint widths are within specifications tolerances.
