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.

 

 

The following video was recorded at our Calgary, Alberta showroom and demonstrates the steps necessary for surface preparation

 

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.

 

The following video demonstrates the installation process for Kodiak Mountain Stone manufactured stone veneer, brick, thin brick veneer and block.

 

 

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.

 

Notes:

  • Packaging quantities vary, contact our stores or call us at 877-563-4252 for information on specific products
  • Kodiak Mountain Stone manufactured stone veneer meets or substantially exceeds the minimum physical requirements specified by the ICC_ES AC51.  View this information at http://kodiakmountain.com/product-specifications/
  • Always use proper safety precautions
  • We recommend you blend stones from different boxes throughout your installation area.  Variations are inherent in all manufactured stone and concrete products.  Questions regarding suitability and/or acceptability must be resolved before installation.  Use constitutes acceptance.  We suggest looking at an actual sample prior to making your final selection.

Stone In Your Home

Posted on

Have you ever noticed that the materials that are originally from nature are the ones that make your home feel fabulous? Stone is one of those materials. Whether it is in the raw sense for a rustic fireplace or it has been polished smooth into beautiful accents around a master bath tub. Stone is one of the oldest home materials since the beginning of civilization and it remains a timeless classic for years to come. If you’d like to incorporate manufactured or natural stone into your interiors, here are suggestions.

1. Strong and natural finishes: From ceiling to floors, manufactured stone and natural stone has an unbelievable quality about it that enables the environment to feel rustic, natural, yet refined. Depending on how rock is finished and what application you use it can change the aesthetic in your home. Consider using flagstone, boulders, and river rock for exterior walls and accents walls for visual interest and wow factor!

2. Stone relaxes the soul: From upscale spas to modern urban lofts, rock and stone relaxes humans and is comforting to have in our environments. Reminiscent atmospheres of natural woods, streams, and river rock connect humans and nature organically. Bring in stone to your bathrooms in stone tile, backsplashes, and shower enclosures to wrap rock and natural stone around your space. Even bathtubs and sink vessels that sit atop a vanity counter can be accented with stone for a completely spa inspired aesthetic.

3. Stately elegance: While rock can symbolize a natural environment, it also embodies stately and royalty too. From medieval castles to modern minimalistic architecture, stone can also be used in brick format to bring an organized and massive aesthetic to your interiors. Consider having your exterior and interior bearing walls made from natural stone bricks. From fireplaces and walls, to your floors, stone bricks can take a meek room to instant grandeur. Custom kitchen accents like fume hoods and backsplashes are another area to bring in rock, the possibilities are endless.

4. Transform your interiors with exterior details: Do you love the interplay between exterior detailing and interiors details inside your home? Stone is the perfect material as it looks at home in both settings. Log cabins, ski resorts, and mountain homes are classic examples of where stone and rock is welcomed inside. Transform a fireplace with a stone hearth or mantle, or use rock for the entire fireplace. Entry foyers that use stone as accent walls and feature walls made from manufactured and natural stone are also popular. Be creative, stone is one of the most durable natural materials there is, go for it!

Natural stone can be strong and commanding, or soothing and serene. Manufactured and natural stone is so versatile that it belongs in every decor. Your entire home can be made from it, or you can keep it in an isolate area such as the bathroom or the kitchen. Either way, try using stone in your home and see how the outdoors can be brought in, without you having to freeze out in nature to appreciate it!

Overview

Alberta is expected to be among Canada’s economic growth leaders. Real GDP is projected to increase by 2.1 per cent in 2013 and 3.1 per cent in 2014. Higher oil prices and a narrowing differential between the price of West Texas Intermediate and Western Canadian Select are supportive of the energy industry. Exports are projected to rise, as is investment, driven primarily by energy. At the same time, expenditures related to flood remediation in Southern Alberta will continue to provide a boost to the economy. Consumer spending will continue to increase as well, supported by population growth and a labour market generating rising wages.

Alberta’s growing economy is expected to generate employment growth of 2.8 per cent in 2013 and 2.3 per cent in 2014.This will keep the unemployment rate relatively low in Alberta at 4.6 per cent in 2013 and 4.5 per cent in 2014.Alberta’s expanding economy and labour market opportunities will continue to be attractive to migrants.

Net migration to Alberta will remain at an elevated level.While economic growth outside of Alberta is expected to improve, it is not expected to slow the annual flow of migrants to Alberta until 2014, as this province is still expected to lead the country in terms of economic growth. Net migration reached 86,939 in 2012 and is projected at 95,600 in 2013 and 68,100 in 2014.

*The point estimate for provincial total housing starts is 34,200 for 2013 and 34,900 for 2014. Economic uncertainty is reflected by the current range of forecasts which varies from 33,400-35,000 units for 2013 and 31,200-38,600 for 2014.

Housing Market Outlook – Canada Edition – Date Released – Fourth Quarter 2013F

Alberta’s Housing Market

Single Starts: Single-detached starts are projected to reach 18,300 units in 2013 and rise to 19,100 units in 2014. In markets such as Calgary, which are experiencing tighter resale market conditions, expect more buyers to look to the new home market to satisfy their housing needs. In both 2013 and 2014, single-detached starts are expected to rise in most of Alberta’s seven largest urban centres.

Multiple Starts: Multi-family starts are projected to reach 15,900 units in 2013 and remain relatively stable at 15,800 units in 2014. In 2014, Edmonton’s multi-family production will pull back after several years of elevated production due to heightened supply levels. Meanwhile, after declining in 2013, Calgary’s multi-family starts will rise substantially in 2014.The shift in multi-family production between Edmonton and Calgary will help keep the provincial total relatively unchanged in 2014.

Resales: In the resale market, MLS® sales are projected to reach 65,000 in 2013 and then rise to 66,800 in 2014.Alberta’s elevated level of net migration will help support housing demand through 2014. In addition to new household formation, employment and wage growth will also support a higher level of resale transactions.

Prices:The average MLS® price in Alberta is projected to reach $379,200 in 2013 and rise to $387,400 in 2014.The sales-to-new listings ratio for Alberta has been trending higher in 2013, indicative of stronger demand relative to supply. As a result, some locations are exhibiting sellers’ market conditions. New listings are expected to increase in 2014 and will moderate the pace of price growth next year.

Building Careers with TeamWorks Training Institute in Lethbridge

Posted on

 

 

 

 

 

 

 

 

Kodiak Mountain Stone is proud to have the opportunity to work with one of our fellow Canadian Home Builder Association – Lethbridge Region members, Teamworks Training Institute in their Building Careers program.

Those involved in the program have learned a lot about the home building industry and have had a lot of hands on experience.  Part of the learning experience has been the building of two sheds.

One of the sheds that they are building will be featured in the 2014 Lethbridge Home & Garden Show and this is the shed that we had an opportunity to be involved with. This week, staff from Kodiak Mountain Stone worked with those involved in the Building Careers program.  We were able to instruct them on the process of stone installation and then coached them as they performed all of the stone work themselves.  They worked with our Dry Stack Ledge (Almond Buff) and did a great job.

At Kodiak Mountain Stone we appreciate the opportunity we get to team up with other members from the Home Builders Association to participate in projects such as this.  The trades in our industry are vital and it is great to see that people are getting the resources made available to them to explore the different trades.

The CHBA-Lethbridge Region is very active in promoting the trades and for more information about the resources available, you can find their contact information at Canadian Home Builders Association – Lethbridge Region

How Do I Clean Kodiak Mountain Stone Manufactured Stone Products?

Posted on

In an article, “New Rules for Cleaning Contemporary Masonry Buildings,” by Gary Henry (Prosoco), MasonryMagazine.com outlines the proper steps to be taken to clean masonry products.

In the article Gary writes about “The New Rules”

 

1. Know Your Surface

“Concrete brick and simulated stone often look like clay brick and natural stone – that’s the idea.  While these various masonry materials often are created to look similar, each has widely different tolerances for cleaner strength and pressure washer psi.”

 

2. Always Test Before Overall Cleaning

“Always test, and always clean under the same conditions in which you tested.”

 

3. Use the Mildest Cleaner and Dilution That Still Gives Effective Results

“Because concrete masonry has some of the same components as the mortar films and smears that have to be removed, cleaners for concrete masonry are gentler than those for clay.  The best concrete and manufactured stone cleaners are precisely balanced — just strong enough to dissolve films and mortar smears that aren’t fully hardened, yet safe enough to do so without harming the masonry.”

 

4. Clean Early and Quickly

This is a problem we have seen time and again.  After the job is completed the person doing the installation doesn’t get around to cleaning off the smears for too long.  Then when he goes to clean up the job it is too late and he can’t get the stone clean.

Don’t give mortar smears and films time to become as hard as the stone itself — remove it while you can still work with it.  With our manufactured stone you can clean it within three to seven days.  If you are working with small, individual areas that you need to remove small amounts of smears, you may be able to work with it sooner than that.

 

5. Use the Right Cleaner for the Right Job

Our suggestion is to use a mixture of water in vinegar to clean our manufactured stone.  Some testing may be required but our guideline as rules 3 and 4 state above is (3) Use the mildest cleaner and dilution that still gives effective results, and (4) clean early and quickly.  You can also talk to one of our experts Contact Us Here for suggestions on mixing ratios.

 

6. Never Clean with Raw Acid

We advise not to use any acids on our manufactured stone products.  Many people ask us about using muriatic acid to clean the stone after installation and our answer is, “no.”

 

Mr Henry also continues by outlining the basic rules that apply to cleaning masonry:

Don’t Spare the Water

He says, “lots of water is one of the secrets of to a great masonry clean down.”   By pre-wetting the masonry the pores of the stone are filled with water and the cleaner will only work on the surface of the stone.  Additional water should be used to rinse and dissolve the excess mortar and dirt.

Clean Bottom to Top, Keeping Lower Areas Wet

“Unlike many other types of cleaning, masonry clean down begins at the bottom and works up, making it easier to keep lower parts of the walls wet.  Keeping the walls wet stops rundown from penetrating into them.”

Follow All Safety Precautions in the Product Literature

This should be common sense and isn’t as applicable with a diluted water and vinegar solution, but it is obviously something that can’t be ignored.

He also goes on to discuss cleaning in colder weather conditions and offers great knowledge.

Why Does Stucco Crack?

Posted on

The American Plywood Association (APA) recently shared this interesting video concerning the proper spacing of plywood and OSB panels.  In the video they demonstrate how much a panel can buckle when there isn’t proper spacing between the panels.

 

“APA recommends a 1/8-inch space between panel edge and end joints. Plywood and oriented strand board (OSB), like all wood products, will expand or shrink slightly with changes in moisture content. If the wood structural panels are tightly butted, there is no room for expansion and buckling can occur. That can mean costly, time-consuming callbacks.” — from http://www.apawood.org/buildertips/pages/M300.html

 

 

In the video they mention that when a panel buckles, the siding materials, roof shingles or floor coverings buckle with it.  When we think about this with stucco applications, we can understand why stucco would crack with the slightest seasonal movement when the wood underneath is butted tightly together.  “So make sure when you are working with plywood or OSB to space all joints 1/8″.”
