Installation Guide
FLAT STONES:
• Calculate the total area for each wall by
multiplying the width by the height.
• Subtract the area for windows, doors and/or
other openings from each wall’s area.
CORNER STONES:
• Measure the height of each outside corner to
get your total linear feet.
• Inside corners do not require corner
stones, as at stones meet to create a
natural corner.
ADJUST NUMBERS
• Multiply the corner stone linear feet (height)
by 50% Coverage will vary by texture.
• Subtract this amount from the total at
stone area.

ESTIMATING YOUR PRODUCT TO SURFACE COVERAGE NEEDS
M-Rock Stone is available in at stones to be applied to the wall surface and corner stones to t around 90 degree outside corners.
INSTALLATION OF M-ROCK’S
TRADITIONAL STONE VENEER
STEP 1: STARTING OFF RIGHT
Prepare your mortar. Mix premixed Type S mortar to a rm, moist consistency. Mortar that is too dry and crumbly will not provide
proper bond. Mortar that is too wet will be weak and messy. Spread mortar 1/2” to 3/4” thick onto a workable area of prepared
surface using a masonry or plasterer’s trowel.The mortar should be applied with sufcient pressure and thickness to fully embed
the lath in mortar. Once the mortar is thumbprint hard, scratch the surface horizontally to create the scratch coat. Do not spread
more than a workable area (5 to 10 sq. ft.) so that mortar will not “set up” before stone is applied.
STEP 2: LAYING OUT YOUR STONE
Opening several boxes and lay out approximately 25 sq. ft. of stone a varying the sizes,
shapes, and colors, allowing for variety and contrast in the design to achieve the desirable
nished project. This is recommended to help you avoid patterns and voids. Break up
long horizontal and vertical lines with stones of varying height and length.
STEP 3: CORNERS FIRST
Apply corner pieces rst if corners are required. Alternate long and short legs in opposite
directions. Once the corner pieces are in place, apply at pieces, working toward wall
center.
TIP:
Working from the top down may help avoid splashing previously applied stone with
dripping mortar. Ledgestone and drystack types should be installed from the bottom
up.
