How Do I Install My Kodiak Mountain Stone Manufactured Stone Veneer?*

Posted on

We often have customers who are the do-it-yourself type or are at least considering taking on the task of installing their own Kodiak Mountain Stone manufactured stone veneer on their project.  We have an Installation Guide on our website that we keep up to date and try to always improve.  Recently we added instructional videos that have been very helpful to many people.  But after having the installation conversations a number of times with customers today I decided to include it in a blog that we could easily share.

 

Kodiak Mountain Stone Installation Instructions*

 

 How Much Stone Will You Need?

Corners (Ordered by the Linear Foot)

  • Determine how many linear feet of 90 degree outside corners you have on the project

Flats (Ordered by the Square Foot)

  • Measure the width and height of the area to be covered in stone and convert it to square feet (width x height = square footage)
  • Figure the square footage of any windows, doors or other areas that will not have stone and subtract that amount from the first figure.
  • Determine the total linear footage of corners that you previously calculated.  Divide that number by two (2) and subtract that amount from the total square footage of flats.
    • Example:
      • Corner linear footage = 20 LF
      • Flat square footage = 100 SF
      • Doors and Windows = 20 SF
      • Flats (100 SF) – Doors and Windows (20 SF) = 80 SF
      • Corners Linear Footage (20 LF) / 2 = 10 SF to be subtracted from total square footage to accommodate corners
      • Total Square Footage Needed 80 SF – 10 SF = 70 SF of flats plus 20 LF of corners
  • We strongly suggest purchasing between 5 – 10% more product than you have calculated

 

Materials You Will Need

 

Over Masonry

For installing Kodiak Mountain Stone manufactured stone veneer over existing masonry (brick, block, stucco, or concrete)

Note: concrete must be in sound condition, clean, not painted or sealed, free from oil, dust and dirt

Mortar:  Used to set stones, and to grout the mortar joint between stones.  We typically sell the premix mortar in our stores but you can use premixed masonry mortar or masonry cement and sand.

Masonry Cement: Mix 1 part masonry cement (Type N or Type S) with 2 1/4 parts masonry sand and potable water.

Premix Mortar: Check with the manufacturer to determine if their product is suitable for installation of manufactured stone.

Bonding Agent:  Latex brush-on or integral bonding agent recommended for this application.

Masonry Sealer:  Use a breathable type, non-film forming sealer, which is available from our Calgary and Lethbridge stores.  It is recommended by some experts feel that any dry stack applications (mortarless joint) should always be sealed.

 

 

Over Framing

For installation of Kodiak Mountain Stone manufactured stone veneer over framing (wood or metal) with sheathing (plywood, OSB, rigid insulations, gypsum, wall board, concrete board, fiber board)

 

Water Resistive Barrier:  Used to prevent moisture from penetrating the exterior wall.

Always check with and follow local building codes for your area.  We suggest two separate layers of tar paper (ASTM D226 no. 15 type 1).

Metal Lath:  Used to hold mortar when forming a mortar scratch coat.  Use a minimum of 2.5 lbs self-furring corrosion resistant metal lath .  For metal buildings or open studs, use a galvanized, rib expanded metal lath.  (minimum 3.4 lb/yd2).  Check your local building codes for other acceptable lath or miss.

Fasteners:  Used to attach lath to the framing members to support the stone system.   Use corrosion resistant fasteners (ASTM C 1063) capable of penetrating wood studs 1″ or metal studs 3/8″.

Mortar: Used to make a mortar scratch coat, to set stones, and to grout the mortar  joint between stones.  You may use premixed masonry mortar, masonry cement and sand, or portland cement,lime and sand.

 

NOTE:  For new construction exterior applications, ensure that all penetrations (doors, windows, etc) are properly flashed and sealed in accordance with manufacturer’s instructions.

Stone Application

Setting Stones in Mortar:

 

  • Completely cover the back of the stone with mortar, at least 1/2 inch thick, and press the stone firmly into the scratch coat to ensure a good bond.  Press hard enough to squeeze out some of the mortar around the edges of the stone.  Make sure you have complete coverage between the mortar bed and the surface of the stone.
  • Corner pieces should be installed first.  Alternate the long and short legs of the corner pieces in opposite directions.
  • After the corner pieces have been installed, apply flat pieces starting at the outside working toward the center of the wall.
  • Cutting and Trimming:  There are a number of methods used to cut, trim and shape stone.  Our suggestion is to use a circular saw with a masonry blade.  When cutting and trimming, ensure you take all safety precautions.  Broken stones should be used to fit into applicable spaces and to fill in gaps.  For the most attractive finished appearance, coat with mortar any cut or broken edges.  Also, try to place cut edges so they are not easily visible.
  • Grouting Joints:  In applications where a mortar joint is used, fill in the joints with a mortar bag, taking care to avoid getting mortar on the stones’ surface.  Joints should be 1/2″ to get the most natural look.  Any accidental smears can be removed with a whisk broom after the mortar is crumbly.  Do not try to remove smears while the mortar is still wet.  Never use a wet brush, wire brush, acid or acid-based products to clean the stone.
  • Finishing Joints:  Proper jointing gives your project an appealing and professional finish.  Before finishing, allow mortar joints to become firm (30-60 minutes, but may vary), then point them up with a jointing tool.  Weather conditions and the type of surface both influence drying time.
  • Brush Joints:  Remove excess mortar and then firmly compress and seal the edges around the stones.  Brush stones and joints with a dry whisk broom to finish and clean the project.
  • Mortarless (Dry Stack) Applications:  In dry stack applications where no mortar joints are used, it is often suggested to add a bonding agent to the mortar mix.  Install from the bottom up and keep joints as level as possible.  Avoid having vertical joints lining up together.
  • Cleaning and Sealing:  Clean Kodiak Mountain Stone manufactured stone veneer products with a soft bristle brush and water.  If stained with mineral deposits or efflorescence, stone may be cleaned with diluted household vinegar solution (7 parts water, 1 part vinegar).  Rinse thoroughly with clean water after cleaning.  Do not use wire brushes or acid to clean Kodiak Mountain Stone manufactured stone veneer.  Seal your Kodiak Mountain Stone manufactured stone veneer products with a breathable, non-filming masonry sealer.  Dry-stacked applications are encouraged to be sealed or any products in harsh environments.

Clearance Information

 

On exterior stud walls, weep screeds and other base flashings should be held a minimum of 4″ above grade or a minimum of 2″ above paved surfaces such as driveways, patios, etc.  This minimum can be reduced to 1/2″ if the paved surface is a walking surface supported by the same foundation supporting the wall.

 

On exterior stud walls where Kodiak Mountain Stone manufactured stone veneer continues down a concrete or CMU foundation wall, and where a weep screed is incorporated into the wall-to-foundation transition, at the bottom maintain minimum 2″ clearance from grade, or 1/2″ clearance from a paved surface.

 

On exterior stud walls where Kodiak Mountain Stone manufactured stone veneer continues down a concrete or CMU foundation wall, with WRB and lath installed won the weep screed at bottom, maintain minimum 4″ clearance from grade, or 2″ clearance from paved surfaces.

 

Where Kodiak Mountain Stone manufactured stone veneer is applied over an exterior concrete or CMU wall, maintain 2″ clearance from grade or 1/2″ from paved surfaces.

 

Over an exterior concrete or CMU wall that is not enclosing conditioned space (e.g. landscape walls, pillars, columns, etc.) maintain minimum 2″ clearance from grade or 1/2″ from paved surface.
