The LATICRETE Quarterly

Quarter 3


President's Message

Ed Metcalf President North America DivisionThe tile business today looks a lot different than it did three years ago. It seems to be harder than ever to “make numbers” while also managing to make a profit. We’re all concerned about that these days.

At LATICRETE, our response to the realities that confront us is to focus on any and all areas of potential growth – including areas that are completely new to us. We believe that there are opportunities for our Distributors and MVP partners, too – and you’ll be hearing more about these from all of us here in the near future.

An area of great interest right now is Manufactured Stone Veneers. These products have evolved from niche markets on the west coast to a nationwide phenomenon. While masons typically do the installation of this increasingly popular finish material, traditional installation methods are not reliable – especially not in cold climate and wet areas.

Our solution to improve such installations is the LATICRETE® Masonry Veneer Installation System (MVIS). MVIS gives the tile contractor the ability to go after a new category of business while offering a superior finished installation – all backed by a LATICRETE Warranty.

MVIS is just one area of innovation that we feel can benefit all of our customers. Read through this issue for the facts about other products and systems that you and your salespeople can focus on to reach out into new areas of opportunity – and contribute to getting your sales back where you want them.


Manufactured Stone Veneers – New Business for Tile Contractors Nationwide


Adhered Manufactured Stone Masonry Veneer (AMSMV) is gaining momentum as a finish material for exterior and interior building cladding. AMSMV is a lightweight manufactured product; cast from cementitious materials that is designed to look like natural quarried stone. AMSMV units are adhered to a structural wall with an adhesive and come in a wide range of finish sizes, facial dimensions, colors and thicknesses. Just look around your community, you will see AMSMV finishes in many applications including building facades, fireplaces, chimneys, columns and free-standing landscaping walls. The acceptance and rapidly growing usage of AMSMV by the design community and building owners alike is a great new way for traditional ceramic tile and dimensional stone installation companies to expand their business opportunities.

Compared to traditional AMSMV installation practices, the products and installation methodology utilized and understood by ceramic tile and dimensional stone installation companies are better suited to the installation nuances and requirements of AMSMV. The following discussion will help us to see why this is the case.

Building Code Considerations

AMSMV falls under the auspices of Chapter 14 Exterior Walls in the 2009 International Building Code (IBC). In addition, further prescriptive requirements of exterior adhered veneer fall under the auspices of Chapter 6 of the Building Code Requirements for Masonry Structures TMS 402-08 / ACI 530-08 / ASCE 5 -08; namely section 6.3 – Adhered Veneer.

The Prescriptive Requirements for Exterior Applications Under the Code are as Follows:

1. Units shall have a minimum thickness of 1/4" (6 mm)+ and shall not exceed 2-5/8" (66 mm) thickness 2. Units shall not exceed 36" (914 mm) in any face dimension. 3. Units shall not exceed more than 5ft2 (0.46 m2) in total facial area. 4. Units shall not weigh more than 15lbs per ft2 (718 Pa) [interior units can weigh up to 20lbs per ft2 (0.958 kg/m2)]. 5. Units that weigh less than 3lbs per ft2 (143 Pa) shall not be limited in facial dimensions. 6. Adhesion developed between the substrate and the adhered veneer shall be a minimum of 50 psi (345 kPa).
+Table 1405.2 – Minimum Thickness of Weather Coverings – Chapter 14 – Exterior Walls – 2009 IBC

The 2009 IBC also dictates that backing structures shall be designed to meet the deflection standard of l/600 under total anticipated load for adhered masonry veneers. It is important to note that the code established deflection standard is utilized in absence of project specific engineered building constructs. Design professionals are empowered to design / engineer the building to lower deflection criteria if deemed appropriate.

Therefore, in many cases, project specifiers have found that the deflection standard of 1/360 under total anticipated load is more practical for finishes such as thin brick, ceramic tile, glass tile and porcelain tile and the deflection standard of 1/480 under total anticipated load is more practical for stone and AMSMV finishes. Consult with the AMSMV manufacturer for more information on deflection requirements.

As with traditional adhered masonry veneer, backup wall constructs consist of concrete, concrete masonry units, wood or steel framed assemblies with fastened lath and plaster systems or cement backer board substrates. Cement backer board applications installed over steel framing in accord with Tile Council of North America Method W-244 (E) is a commonly specified installation system for adhered veneers

Specifiers can use the CSI Master Format section 04 73 00 Simulated Stone (or 04 70 00 Manufactured Masonry) section to reference and specify AMSMV units and installation methodology. Ceramic tile and dimensional stone installation contractors can seek out this additional work in their bids by referring to this section in building specifications when estimating projects. An additional bid can be submitted under this specification section.

Inform the general contractors, construction managers and architects that you work with that your firm can perform AMSMV work in addition to typical ceramic tile and dimensional stone work. Under certain circumstances, AMSMV work may be bundled with other masonry work specified under section 4. Negotiations with owners / general contractors may be required to carve out this specific section from other masonry work to submit a specific bid for the AMSMV work only. This would be no different than when owners / general contractors bundle all of the flooring finishes together on a project (e.g. carpeting, resilient, laminate, wood, ceramic tile, stone). In many cases, owners / general contractors will allow subcontractors to submit bids on the individual finish types and award work accordingly. Submission and timing of AMSMV bids are also a factor. Typically, division 4 work bids earlier than division 9 work. Therefore, ceramic tile and dimensional stone contractors may need to view, estimate and submit bids for AMSMV work earlier in the construction process.

In addition, ASTM standards are under development for AMSMV units under the oversight of ASTM International Committee C15 on Manufactured Masonry Units; namely subcommittee C15.11–ASTM WK12802 – New Specification for AMSMV Units.

Traditional Installation Methodology

Until now, AMSMV units have been treated like traditional brick or natural quarried stone and installed with the same type of mortars; Type S or Type N masonry mortars.

Depending on the substrate type, two layers of a weather resistive barrier (e.g. 15 lb builders felt) and galvanized wire lath is fastened to the structure / substrate prior to the installation of the AMSMV units. In many cases, the wire lath is floated with a portland cement based plaster. The plaster is typically applied in a two coat process; scratch coat (~1/2 {12 mm} thickness) and a brown coat (~5/8 {15 mm} thickness).

This traditional method requires that a slurry of neat portland cement mixed with water is brush applied to the back of the units and then bedded into the Type S or Type N mortar (~3/8 {9 mm} mortar thickness after beat in). As the units are tapped into place, the mortar squeezes into the mortar joints and grips the edges of the units. Then additional mortar is placed into the joints and pointed to the desired finish.

Consult with the specific AMSMV manufacturer for complete installation information including flashing, weep screeds, expansion joints and other critical detailing elements.

The Problem

Unfortunately, traditional site mixed masonry mortars fall short in their ability to withstand the demanding conditions that AMSMV typically face – they simply don’t have the adhesion strength or durability to withstand the rigors of such an installation. Therefore, many of these installations experience bond failure as the veneer separates from the substrate and eventually falls off the building (see figure 4). In many cases, Type S and Type N masonry mortars do not even achieve the code prescribed shear bond strength requirement of 50 psi (345 kPa). This is due to the fact that Type S and Type N mortars are not designed to achieve high shear bond strength; they are typically used to bed brick, block and stacked stone and therefore, shear bond strength is not one of this mortar’s better qualities – it’s just not designed for it.

A major problem is that traditional AMSMV applications typically only use damp-proofing / weather proofing membranes (e.g. 15 lb builders felt) in lieu of true waterproofing membrane products. Therefore, water infiltration is a common problem associated with many AMSMV applications as the damp-proofing / weather proofing membranes are not sufficient to prevent water infiltration. This problem is magnified as the water infiltration also causes freeze / thaw damage in colder climates and thermal expansion problems in warmer climates along with corrosion of the wire lath and its fasteners (see figure 5). The Type S and Type N mortars described above are also susceptible to this damage.

The brief history of AMSMV has demonstrated that more robust installation products and methodology are required. This is where familiarity with installation materials and methodology commonly used by ceramic tile and dimensional stone installation companies comes into play along with proven technology and innovation from LATICRETE.

The Solution

The LATICRETE Masonry Veneer Installation System (MVIS) is a solution to all of the problems associated with typical AMSMV installations. Utilizing a combination of our proven materials and methods with innovative new products, LATICRETE provides a complete installation system that offers long-term dependable installations backed by either a LATICRETE 25 Year System Warranty* or a 10 Year System Warranty for Steel or Wood Framed Exterior Facades**).

Flood Testing Shower Pans

The practice of flood testing tile and stone installations which will be subjected to continuous submersion (e.g. swimming pools, fountains, etc…) or a significant amount of water flow (e.g. showers) is a critical step to ensuring that no damage is done to a structure due to water leakage. All too often this vital step is not performed due to time constraints, or is performed improperly, or any results obtained from a flood test are not recognized for what they are. The purpose of this article is to provide a guide to properly conduct a flood test for installations to receive tile or stone as a finish material. Conducting a flood test properly can provide a measure of confidence that the waterproofing system performs as expected and provides a watertight installation for the service life of the system. Please note that ASTM D5957 “Flood Testing Horizontal Waterproofing Installations” is the ASTM method from which this article draws much of its information. For a more complete reference please visit www.astm.org to purchase a copy of the complete standard. Please note that design professionals, engineers and others who are contractually obligated to a specific project may devise or require other means and methods to conduct a flood test.

Shower Pans and Horizontal Applications

The purpose of this section is to provide a procedure for flood testing a horizontal waterproofing installation having a slope which is not greater than 1/4” per foot (20 mm per m), or 2% slope. These applications would include shower pans, patios/decks, parking garages, or most slopes to drains in commercial or industrial applications. Flood testing should be performed prior to installation of any materials on top of the waterproofing membrane or material. Prior to beginning the flood testing, inspect the waterproofing membrane (e.g. LATICRETE Hydro Ban™ or LATICRETE 9235 Waterproofing Membrane) or other approved material type for any voids, pinholes or other imperfections. Repair any observed problems as stated by membrane manufacturer’s installation instructions. Plug all drains within the area to be tested with suitable plugs. Fill the area around the plug and drain to check for leaks around the plug before proceeding with the full test.Flood the area being tested with potable water to a minimum depth of 1” (25 mm) to a maximum depth of 4” (100 mm) at the low point of the test area. The mean (average) water depth should not exceed 2 1/2” (65 mm). Water added to the area to be tested must be at a pressure that will not damage the membrane and will not flow onto any lapped edges. In case of any leaks it may be best to have a contingency plan in effect to deal with the water. If the flood test is being performed in an exterior environment, the testing should not be performed if rain is anticipated to occur during the test period.For accurate measurement of water loss due to environmental conditions (evaporation, wind, etc…) it would be a good idea to place a watertight, flat-bottom, vertical-sided shallow pan to the approximate depth of water in an adjacent area which will be subjected to all of the same environmental conditions as the test area. At pre-determined points, in both the area being tested and the shallow pan, measure the water at the beginning and end of the test. Calculate any changes in water depth in the area being tested and the shallow pan. If the difference in depth in the area being tested is substantially greater than the shallow pan, then membrane leakage is probable. Flood tests should be conducted within a time range of 24 – 72 hours, with the time for testing to begin when the water has reached its maximum test depth. It is important that flood testing be constantly monitored, so plan accordingly. If unexpected rain or water addition takes place during the test period, the test should be discontinued prior to the water flowing above the containment edges. The addition of any water after testing has commenced will also render the flood test as inaccurate and should be stopped. Monitor any spaces below the area being tested for signs of water infiltration at 1 – 2 hour intervals until completion of flood test. If any leakage occurs during the flood test, the water should be immediately drained, the leak source found and repairs made as recommended by membrane manufacturer.
If repairs are made to the waterproofing system, it will be necessary to conduct another flood test to ensure that complete waterproof integrity is achieved. A flood test is considered to be complete if no leaks are determined to exist during the test period, and, the membrane and any flashing are considered to be intact.Allow the waterproofing membrane to cure for a sufficient amount of time based on the membrane manufacturer’s instructions based on temperature and humidity. LATICRETE products ideal for these installations include; LATICRETE Hydro Ban, a single component, self-curing, load bearing liquid rubber polymer waterproofing/crack isolation membrane that does not require the use of a reinforcing fabric. LATICRETE Hydro Ban can be flood tested in as little as 2 hours at 70°F (21°C) or higher †. Refer to LATICRETE DS663.5, available at www.laticrete.com for more information.LATICRETE 9235 Waterproofing Membrane, a self-curing, load bearing, liquid rubber polymer and reinforcing fabric which forms a flexible, seamless waterproofing/crack isolation membrane. LATICRETE 9235 Waterproofing Membrane requires 7 days cure time at 70°F (21°C) or higher. Cooler temperatures require a longer cure time. LATICRETE 24hr HydroProofing™ is a 3 component, epoxy-based, trowel applied waterproofing membrane which is specifically designed for use under ceramic tile and stone and can be flood tested in 24 hours at 70°F (21°C) or higher. Please refer to LATICRETE TDS169 “Flood Testing Procedures” for information on flood testing continuous submersion areas.

LATICRETE Plant Manager Driving Toward a Championship

August 31, 2009: LATICRETE sponsors its Hamlet, North Carolina, plant manager and Team LATICRETE race car driver Ron Munnerlyn in the Sports Car Club of America sanctioned Improved Touring classification. Munnerlyn drives a modified Mazda Miata at racetracks all around the Southeast in search of the season championship, and currently ranks in the top three with four first-place finishes in only five races.

It hasn’t been an easy road for Munnerlyn and Team LATICRETE this season, fighting engine trouble that began at the Memorial Day events at Carolinas Motorsports Park in Kershaw, South Carolina, and carrying over to the Heart of Dixie SARRC at Nashville Superspeedway.

In perhaps his finest moment of the season, Munnerlyn turned a bad situation into another win under the most unlikely circumstances. At the Memorial Day race in Kershaw, South Carolina, Team LATICRETE could not get its Mazda Miata running properly and missing the morning qualifying session that determines the starting position for the main event. Thinking quickly, Munnerlyn rented a car from a fellow competitor and somehow managed to drive Team LATICRETE to another checkered flag. Starting in last place, and driving a borrowed car, Munnerlyn captured his fourth win of the season to bolster his hopes of advancing to the championship.

LATICRETE & Rio Grande Sponsor CTEF Certification Test

On May 14-15, 2009, LATICRETE and Rio Grande Company co-sponsored the CTEF ceramic tile installation certification test, the first of its kind in Colorado. Held at Rio Grande Company’s facility in Denver, twenty LATICRETE MVPs took the certification test over a two day period. With the help of LATICRETE materials, along with tile and backerboard donated by Design Materials Inc., CTEF was well equipped to conduct the hands-on portion of this testing event.

Stephanie Samulski of the CTEF said, “Rio Grande and LATICRETE really stepped up to the plate to make taking the certification test doable for the Denver-area contractors that participated. That was especially appreciated by the contractors, who still had to pull their installers out of the field for two days to test. This helped us get a large group tested, one of the largest to date, and this is critical to making the CTEF certification meaningful. The sooner we identify the best installers out there, the sooner manufacturers and distributors, like LATICRETE and Rio Grande, can start telling customers to use CTEF Certified Tile Installers.”

LATICRETE Donates to Extreme Makeover: Home Edition - Indianapolis

LATICRETE donated all the tile installation products for the overwhelmingly popular prime time ABC television program Extreme Makeover: Home Edition – Indianapolis. Hosted by Ty Pennington, the two-hour season finale aired on May 17, 2009, documenting and celebrating a brand new home for Bernard McFarland and his three sons in the Martindale-Brightwood neighborhood on the city’s blue-collar, near northeast side.

LATICRETE contractor sales representative John Holliday directly supplied the new McFarland home with innovative products from the LATICRETE manufacturing facility in Indianapolis. The new home, built by Estridge Homes, features porcelain tile donated by Daltile in the kitchen, backroom, laundry room and mud room, as well as all bathrooms. In addition, Daltile supplied 24” x 24” large-format porcelain tiles which were spot-bonded as a full-wall fireplace surround with LATAPOXY 310 Rapid Stone Adhesive, quickly applied with the LATAPOXY 310 Cordless Mixer. With only one-week to complete the home, LATAPOXY 310 Rapid Stone Adhesive, with its remarkable bond strength and five to seven minute cure time, sped-up the installation of the fireplace surround and allowed much quicker access for the other trades involved in the Indianapolis episode of Extreme Makeover: Home Edition.

LATICRETE MVP (Most Valued Partner), Tremain Tile, Marble & Granite, family-owned since 1921, provided the crew that installed all of the tiles throughout the house with the donated LATICRETE products. The porcelain tiled floors and bathroom walls were set with LATICRETE 254R Platinum Rapid, a one-step, polymer fortified multipurpose thin-set adhesive, selected for its fast cure formula, performance and versatility.

To grout all of the tiles, including the fireplace surround, Tremain Tile, Marble & Granite used LATICRETE PermaColor™ Grout at Bernard McFarland’s new home for his three sons. LATICRETE PermaColor Grout is quickly becoming one of the premier cement-based grouts in the tile and stone industry with its long list of benefits for both the contractor and customer. GREENGUARD® certified and Kevlar® reinforced, LATICRETE PermaColor Grout offers the maximum performance available in a cement-based grout with long-lasting, consistent color. LATICRETE PermaColor Grout is ideal for both floors and walls, which means only one product to carry and mix at the jobsite.

The Emmy award winning reality program “Extreme Makeover: Home Edition,” now in its 7th season, is produced by Endemol USA, a division of Endemol Holding. It’s executive-produced by Anthony Dominici. David Goldberg is Chairman, Endemol North America. The show airs Sundays from 8:00-9:00 p.m., ET on ABC.


LATICRETE Donates Products for Ty Pennington’s Hit Reality Show on ABC

LATICRETE donated the tile installation products for the Suffield, Connecticut episode of the ABC hit reality show Extreme Makeover: Home Edition, starring Ty Pennington. The Hill family episode was filmed on location in consistent rain the last week of June, and is set to air this fall as the first episode of the show’s seventh season. LATICRETE supplied Mason Tile with top of the line, GREENGUARD certified products including LATICRETE 254R Platinum Rapid, LATICRETE 255 MultiMax™, and LATICRETE PermaColor Grout, for a combined total of 1,700 square feet of floor and wall tiles. LATICRETE PermaColor Grout is a high-quality, cement-based grout ideal for both interior and exterior floors and walls.

“The LATICRETE products were great,” said Mike Mason, owner of Mason Tile in nearby Longmeadow, Mass. “The rapid-setting adhesive was huge. It would have been impossible to finish the work without it. We only had a few hours between setting and grouting with so many people trying to accomplish different tasks in such a short timeframe. We set tile over backer board in some areas and concrete in others, and had no difficulties whatsoever.”

Led by Pecoy Signature Homes, Pennington and nearly 4,000 volunteers, the Extreme Makeover Home Edition team demolished a rundown 2,200 square foot ranch and replaced it with a 5,500 square foot, Federal-style home in just 106 hours for the family of William and Catherine Hill. Since leaving the Hartford projects in 1991, the Hill’s had been raising four of their own children and seven nieces and nephews in their modest ranch on Mather Street in Suffield, a rural Connecticut River Valley town between Hartford and Springfield, Mass. William Hill, a retired veteran of the U.S. Army and two tours overseas in Iraq and Pakistan, returned with his entire family from an all-expense paid trip to Disneyland on Sunday, June 28 for an emotional unveiling of a new two-story, six-bedroom home in front of thousands of overjoyed volunteers and neighbors.
