Installation
Preparing the Surface
Apply a moisture barrier directly to the wood surface starting from
the bottom and working your way up. Cover moisture barrier with
a galvanized metal lath according to local building codes. Overlap
metal lath min. 4” on vertical seams and 6” on horizontal seams.
Wrap lath around corners min. 16”.
Applying Scratch Coat
Apply masonry scratch coat over metal lath evenly approx 3/8 – 1/2”
thick. Press mix into the holes of the metal lath keeping surface
fairly flat and even. Use a soft brush to lightly rough up the surface.
Mortar Mix
Use 1 part Masonry cement Type N to 2 – 2.5 parts masonry sand.
Mix with water to an even moist consistency. Use materials that are
clean and free from salts and chemicals.
Applying the Stone
Install corners first and work from the top down. Apply a half-inch
layer of mortar to the back of the stone. Press the stone against the
wall using even pressure across entire stone while gently rocking the
stone into place. When using a stackable pattern, take care to keep
stones level. Mortar consistency may need adjusting depending on
weather conditions. Cut stones to length as needed using a masonry
blade or stone nippers.
Grouting & Striking Joints
Use 1 part masonry cement to 2 parts sand for the grout mix.
Grouting can be done using a grout bag. Fill grout joint completely
being careful not to miss any voids. After grout mortar becomes
firm to touch, you can strike the joints with a striking tool or hardwood
stick. Lightly brush excess dust from stone.
Cleanup
Remove mortar residue from face of stone with water and soft brush
the same day of installation.
Precautions
YoderStone should not be installed closer than 4” to the final grade.
This will keep freeze soil from applying pressure to stone and help
keep stone clean as well as provide better drainage. A good water
based acrylic sealer is a good idea in high moisture areas.
