2. Evolve Stone requires a fully installed water and airtight WRB system prior to the install of
the drainage mat and pin nailed stone. This WRB system includes flashings, self-adhered
joint tapes, flashing tapes, sealants and door and window watertight installations. The
Evolve drainage mat requirements ensure a clear drainage and drying path.
3. The bottom of the 1/8" drainage mat must be left open to allow for water drainage and air
circulation. If an insect barrier is requested, we suggest two methods.
• Simply wrap the excess fabric under the bottom of the mat and attach to the back of
the mat by securing in place with cap nails
• Supply and install a fabric wrapped corrugated drainage starter strip as manufactured
by MTIdry or Equal. Ensure the corrugated strips match the 1/8" mat thickness.
See Detail #2. (MTIDry.com Model #CLSS2316)
4. Evolve Stone must be installed into a minimum of a 7/16" OSB or plywood that is
structurally attached to the studs placed at 16" O.C.
5. The sheathing must be placed and fastened as per code, APA instructions and the
manufacturer’s instructions. This substrate must not be water compromising or degraded
by the environment or other condition. Evolve Stone must be nailed to a sound structural
sheathing intended to receive and hold finish nails.
6. When abutting Evolve Stone against different materials (trim, windows, doors, etc), make
sure to check other MFG’s for any hold-off or spacing requirements.
7. Additional nails may be used to mitigate wobble. Installer needs to periodically check for
loose stones or dry-fires.
1.2 Setup
Using a chalk-line, make level guidelines spaced at regular intervals up the wall to assist in the
installation. The stone veneer product does not need to terminate at these guidelines and the
stones may overlap them. These guidelines are used only to ensure that the courses are being
applied to the wall in a level fashion to reduce the possibility of skew.
Pro-Tip: using a laser level may help you to layout your chalk lines to mark out better course
guidelines and eliminate potential sagging in the center of your layout.
2.0 Stone Application
2.1 Nail Pattern Guidelines
To fasten Evolve Stone products to the wall, adjust the countersink depth on the finish
nailer to ensure that the nail heads will recess slightly below the surface of the stone.
Apply 16-gauge stainless steel finish nails in the arrangements depicted below based on the
stone’s size. 304 grade stainless steel to be used for standard exterior applications. 316 grade
stainless steel is required in extreme or coastal environments.
2.1.1 Small Stones:
For stones that are less than 10" long
and less than 5" tall, apply two or more
16-gauge stainless steel finish nails at
slight angles into the stone on the left and
right sides along the horizontal centerline
