Installation Instructions

(1)  Caution: Product contains Crystalline Silica. Dust from 
cutting or sawing may create possible cancer hazard. Dust may 
cause irritation of the nose, throat and respiratory tract. Avoid 
prolonged or repeated inhalation of dust. A properly fitted, 
particulate-filtering disposable 
NIOSH approved N-95 series 
face piece respirator (“dust mask”) should be used when 
mechanically altering this product (e.g., sawing, cutting, 
drilling or similar dust generating processes). Wear a long-
sleeved shirt, long pants, gloves and safety glasses with side 
shields when handling and installing material. Wash hands and 
face with soap and warm water immediately after handling.
MORTAR (CONTINUED)
Mortar Admixtures: Comply with ASTM C1384 Bonding 
Agents: Comply with ASTM C1059 or C932 Coloring 
Pigment: Comply with ASTM C979
All mortar, additives, bonding agents and pigments must be stored, mixed and used in strict accordance with the 
manufacturer’s instructions and appropriate standards referenced above. 
Notes: Refer to MVMA Installation Guide Table 2 (www.masonryveneer.org) for additional guidance with mortar selection by 
application. Under mixing, over mixing, tempering and open times of mortar can impact bond. Follow mortar manufacturer’s 
instructions.
STEP FOUR:
ESTIMATING THE 
STONE REQUIRED
Determine the amount of Modulo Stone products needed by measuring the area to be covered. Measure the length times the 
height to arrive at the gross square footage of flat stone needed. Subtract square footage for window, door and other 
openings. Measure the linear feet of outside corners to determine the amount of corner pieces needed. One linear foot of 
corner pieces covers approximately ⁄ of a square foot of flat area. Subtract the flat area covered by the linear feet of corner 
pieces from the square footage of flat stone required. You may wish to obtain some extra stone to allow for cutting and 
trimming, or tighter joints. In addition, be sure to verify whether the texture chosen is sold based on coverage with a ⁄" 
mortar joint or tight-fitted. Most texture coverages are listed for a ⁄" joint, the exceptions being dry-stack.
