Installation

• Estimating stone requirements

  • Measure area to be covered, width and length for total square footage
  • Measure the length needed for outside corners
  • Deduct lineal footage from total square footage of A - (1 lineal foot equals approximately 3/4 sq. ft) to get square footage of flats required
  • Extra stone may be needed for trimming and cutting

• Tool requirements

  • Hammer/Staple Gun (applying weather resistant barrier and/or metal lath
  • Metal Joining Tool/Wood Stick (finishing mortar joints)
  • Plasterer’s and/or Mason’s Trowel (applying mortar)
  • Grout Bag (grouting joints)
  • Wheel Barrow and Hoe (mixing mortar)
  • Level (setting hearth slabs)
  • Circular Saw with Carborundum Blade (cutting hearth pieces)
  • Wide mouth Nippers/Hatchet (trimming stone)
  • Whisk Brush (cleaning finished work)

• Accessory materials

  • Mortar Components

    1. Premixed

       Type S mortar

    2. Or component mix

       Premixed Type S mortar mixture

       • 1 bag Type S mortar
       • 3 bags masonry sand (same size bag as Type S mortar
       • 1 and half litres keracrete per bag of Type S mortar
       
       This amount of material will cover approximately 60 square feet
       
       
       • The above quantity of material includes the scratch coat over the wire including keracrete mixed in mortar
       • Includes mortar to apply the stone to the scratch coat with keracrete mixed in the mortar
       • Included mortar for grouting the stone the stone. DO NOT MIX KERACRETE in the grout mixture
       • Before applying mortar to stone, paint keracrete on the back of the stone with paint brush
       
       

       Portland Cement Mortar Mixture

       • 1 bag Portland cement
       • Half bag of hydrated lime
       • 3 bags masonry sand (same size as Portland cement)
       • 1 and half litres of Keracrete per bag of Portland cement

    3. Mortar color

       iron oxide colour (if desired). (Be advised that mortar colour cannot be washed off face of stone, apply carefully)

  • Weather Resistant Barrier

    Barrier shall be equal to U.B.C. Standard No. 32-1 for asphalt saturated rag felt, or U.B.C. Standard No. 17-1 Kraft waterproof building paper.

  • Metal Lath

    1. Minimum 2.5 lb. Expanded metal lath (diamond mesh) galvanized
    2. Or 18 gauge galvanized woven wire mesh
    3. For metal buildings - minimum 3.4 lb. 3/8" rib expanded metal lath galvanized
    4. Continuously wrap weather resistant barrier and metal lath a minimum of 16" around all inside and outside corners

  • Fasteners

    1. Galvanized nails, and/or staples, and/or concrete nails
    2. 1/4" type S-12 Pancake Head Super Tite screws

• Mortar

  • Mixing Mortar

    Mortar should be mixed to a firm, moist consistency. Mortar that is too dry and crumbly will not provide proper bond. Mortar this is too wet will be weak and messy. Do not use antifreeze compounds to lower the freezing point of mortar.

  • Applying Mortar To Surface Arear

    Using a plasterer’s or mason’s trowel, apply mortar 1/2" to 3/4" thick to prepared surface area. Do not spread more than a workable area (5 to 10 sq. ft.) so that mortar will not "set up" before stone is applied.

• Surface Preparation

  Use the following chart to determine the correct surface preparation for your installation:
  
  

  WALL SURFACE	INTERIOR & EXTERIOR PREPARATION REQUIRED
  Rigid Backwall Wallboard Plywood Paneling Wall Sheathing Concrete Board Polystyrene Insulation Board	Cover sheathing with a breather type weather resistant barrier, lap joints 4" shingle fashion. Then in accordance with local building code, lap and install lath or mesh using galvanized nails or staples 6" on center vertically, penetrating studs a minimum of 1". Continuously wrap weather-resistant barrier and metal lath a minimum of 16" around all outside and inside corners.
  Clean & Untreated Concrete Masonry Stucco	No preparation needed. Examine newly poured concrete closely to ensure that its finished surface contains release agents. If is does contain form oil, etch surface with muriatic acid, rinse thoroughly and/or score with a wire brush.
  Dirty, Painted or Sealed Concrete Masonry Stucco	Sand or waterblast to original surface (remove dust by washing) or securely attach lath.
  Metal Buildings	Lap and install paperbacked 3/8" rib expanded metal lath to metal cladding supports of 20 ga. to 12 ga. using United States Gypsum Company's 1-1/4" type S-12 Pancake Head Super Tite Screws. Screws must penetrate 3/8" beyond the inside face of metal surface. Screws are to be installed on centers equal to 1 screw/sq.ft. and shall not exceed 6" on center in one direction. Apply 1/2" to 3/4" scratch coat and allow to dry 48 hours.
  Open Studs Polystyrene Insulation board installed over open studs	Lap and install paperbacked metal lath to studs using nails which penetrate a minimum of 1" at 4" on center. Apply 1/2" to 3/4" scratch coat and allow to dry 48 hours

  
  Please Note: All installations should be in accordance with local building codes, and approved by the job engineer.
