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
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
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!
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.
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.
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.
