Installation Instructions

Sakala Stone Products are able to be installed by most “Do-it-yourselfers.” If you need any additional installation assistance, please contact Sakala Stone Products.

Step 1 - Prepare the Surface
Apply stone directly to clean unsealed, unpainted or untreated brick, concrete block, or other masonry surface. Install a galvanized metal lath to all other surfaces.

On painted block, pre-drill holes in block joints to depth of 1 inches (hammer drill and good masonry bit recommended) every 12 inches. Nail up galvanized metal lath using 1-1/4 inch masonry nails with washers.

On metal surfaces, attach the lath with self-tapping screws every 12 inches to 16 inches.

On exterior wood framing surfaces, use 30# building felt paper or unperforated house wrap over any exposed wood to form a vapor barrier. Attach the lath by using 1-1/4" roofing nails every 6 inches, securing to studs whenever possible.

On interior framing over drywall, secure lath through the drywall to studs using drywall screws of appropriate length. Where lath is loose, drive in drywall screws downward through lath into drywall at a 45 degree angle.

On interior framing over plywood/OSB, secure metal lath with 1-1/4 inch roofing nails every 6 inches.

Always attach lath right side up with small cups pointing upward. Building paper should be applied on exterior
Step 2 - Apply Mortar to the Surface

Use type "N" or "S" mortar. Mix 2 parts of fine masonry sand to 1 part mortar.

Example: 1/2 bucket of Mortar mixed with 1 bucket of sand.

Mix mortar with just enough water for workable consistency – like peanut butter. Apply a coat of thin mortar, 1/2 inch to 1/4 inch thick.

IMPORTANT: DO NOT USE PRE-PACKAGED MORTAR MIX!
Step 3 - Apply the Stone

Lay out stones at random. Install corner stones first. Remaining stones should be applied by working from the top down to prevent oozing mortar from splattering the stonework below. Joints between the stones should be of a consistent width.  Dry Stack style should be installed as tightly as possible, working from the bottom up.

Mortar can be a bit softer for this step – like pudding. Apply 1/2 inch of mortar to back of stone. Press stone firmly into place with a gentle wiggling motion to promote bonding. The mortar on the back of the stone should squeeze out and surround the stone.
Step 4 - Remove/Dress Excess Mortar

Fill in joints using a grout bag, working up through the joints. Once the mortar firms up, use a wooden or metal striking tool and remove excess mortar. (An old flat-head screwdriver is perfect). At the same time, firmly press mortar into the joints so edges are thoroughly sealed.

Tip: Timing is critical. If mortar is too wet, it will smear; too dry and it will crumble. Watch closely as it sets before striking the joints.
Step 5 - Clean Stone
Clean off any remaining mortar from the stone with a stiff bristle brush.

Brush off any loose mortar on the face of stones. Never let mortar set overnight before brushing joints.

TIP: Keep hands and tool handles clean while working to eliminate smudges on the stone.  DO NOT TRY TO WIPE MORTAR OFF OF THE STONES.  It will only smear.
