Using the NTCA Reference Manual to prevent or solve radiant heat issues

Radiant heat and electric floor warming is one of the fastest growing sectors in the tile industry. More and more products are being introduced that take advantage of NEST or smart phone technology to monitor and operate automated temperature controls, or new mat-and-cable configurations that speed installation while offering a more custom layout and guarding against cracking at the same time.

Electric floor warming systems seem to get simple to install all the time – a far cry from the days of cumbersome hydronic pipe systems. These simple, easy mat-and-cable systems make installation fast and relatively easy.

That being said, there are cautions when installing radiant heat systems that are best heeded to ensure a flawless project. The 2016/2017 NTCA Reference Manual examines Radiant Heat Issue for Tile & Stone Installations in chapter 6: Specialized Installation Procedures, page 134. Presented in a Problem/Cause/Cure format and compiled from decades of field experience, the recommendations in the NTCA Reference Manual help installers prevent problems in the field and give guidelines on managing them if they do occur.

For instance, a few of the scenarios include:

Problem: Excessive tile lippage

Cause: Lack of mortar of self leveling underlayment cement used to encapsulate the radiant heat system

Cure: Securely attach the radiant heat system so it stays flat on floor and cover the system with sufficient mortar or self leveling underlayment cement. 3/4” of dry pack of 3/8” SLU over the system.

Problem: Grout or mortar system is very powdery or weak.

Cause: Provided the grout and mortar system was properly mixed and installed, the main cause would be running the radiant heat system before the cement based products are allowed to cure: a minimum of seven days.  Excessive moisture exposure from below or above may impact mortars or SLUs.

Cure: Make sure all parties involved with the radiant heat system know the system cannot be put in service until the installation products are allowed to cure.

Problem: The thermostat overheats or even melts when the radiant heat system is turned on.

Cause: Damage of this type generally is caused by overloading the circuit, trying to heat too much floor area on one thermostat or running a 120v thermostat on a 240v circuit.

Cure: Make sure the radiant heat system is matched in terms of voltage and sized correctly to the circuit capacity and thermostat. It also could indicate the wire nuts are not sufficiently tightened. Make

sure a licensed electrician makes the final connection.

Problem: The radiant heat system doesn’t warm up.

Cause: The main reason for this is a broken or severed heating element.

Cure: Take care to protect the heating system during installation. This problem will require splicing/repairing the heating element.

Problem: The radiant heat system doesn’t provide evenly spread or consistent warmth.

Cause: The main reason for this is varying or wrong spacing of cables or tubes. Follow manufacturer’s recommendations. Lack of insulation under the heat system may also cause heat-loss or heat-sink in areas of the subfloor. Proper insulation underlayment should be designed by the architect.

Cure: Re-design floor and heat system installation including insulating tile underlayment. This cure will require splicing/repairing the heating element. In case of heat loss due to lack of insulation under the heat system, the application must be redesigned.

Qualified Labor – March 2017

The Benefits of Certification

By Terryn Rutford, Social Structure Marketing

The Certified Tile Installer (CTI) program run by the Certified Tile Education Foundation (CTEF)  encourages installers to test their skills against industry standards. It offers industry members the chance to establish their place among the best and brightest installers. During Total Solutions Plus in

Dirk Sullivan

Palm Desert last October, several NTCA members were interviewed about the benefits of certification.


 “It really is a way for me to categorize my installers as well as let them know where they stand,” said Dirk Sullivan, NTCA state ambassador for Oregon and owner of Hawthorne Tile, and State Ambassador. “It helps them want to move forward in the industry and to know what they have to do to get there.”

Martin Brookes



The CTI program leads to better installations and increased wages across the industry. Martin Brookes, with Heritage Marble and Tile in Mill Valley, Calif., and NTCA 2nd Vice president said, “We’ve had great success using the program to elevate workmanship,  to elevate the confidence of our guys to do higher-end installations, and higher commitment to the standard of quality of

Brad Denny

work. It’s been really advantageous to Heritage Marble and Tile.”



As the industry rises in reputation and reliability, its members benefit. “The CTI program allows me to offer something to my customers that not everyone else can,” said Brad Denny, NTCA regional director and State Ambassador, and project manager at Nichols Tile & Terrazzo Co. Inc., Joelton, Tenn.

Erin Albrecht


In addition to being a benefit to the installer, the CTI program is a boon to the installation company. “We’ve been located by people across the country using the database through the CTEF and NTCA websites,” said Erin Albrecht, chief operations officer of J&R Tile in San Antonio, Texas. And every year the construction industry is recognizing certification as more important.

James Woelfel

Artcraft Granite, Marble & Tile Co. saw a huge financial benefit after receiving a request for certified installers. “Five years ago we had an owner call us and say, we’re looking for CTEF-certified installers and we can’t find anyone who knows what they’re doing,” said James Woelfel, Artcraft vice president and NTCA chairman of the board. “It generated at least a billion dollars worth of work over the last six years,” he said.

Overall, certification raises the industry standard and encourages quality installation. “I think what we have seen is a different culture of

Kevin Fox

professionalism in the trade,” said Kevin Fox, president and owner of Fox Ceramic Tile, Inc., in St. Marys, Kan., and chairman of the NTCA Methods and Standards Committee. “It took us a while to get a buy in on it. We have a lot of installers that have been doing [installation] for 20 to 30 years, so it took me a while to convince them to validate their skills. We need those skills validated as a company as we’re talking to general contractors, especially those who aren’t familiar with us. And we also need it validated for even repeat customers that are looking for clients that will provide a consistent product.”

Martin Howard

The tile industry is moving toward certification as a standard. Martin Howard of David Allen Company in Raleigh, N.C., and current NTCA president observed, “It really does set you apart from your competitors and it also validates your skill and it validates the knowledge that you have and the hard work you’ve put in to get where you are.” The more installers who are certified the better off the industry is as a whole.

Jan Hohn

Jan Hohn of Hohn & Hohn, Inc., in St. Paul, Minn., said, “It was a selling point I could talk to general contractors about, to architects, and designers to let them know we had passed a national test and it said we were qualified to install tile.” As more contractors, architects, and designers recognize certification as evidence of quality installers, certification will become ever more important to the industry and its members.

NTCA University Update

By Becky Serbin, NTCA training and education coordinator

This month we will be reviewing two Apprenticeship courses: the History of Tile, and an Introduction to Trims and Profiles.

History of Tile

The History of Tile course was very interesting to create, and it may not have been finished if we didn’t have the help of the Tile Heritage Foundation in putting the timeline and content together.  The course starts with an overview of world history and the creation of the tile industry as we know today by Herbert Minton in 1843.  The course then moves into reviewing tile styles and trends through different periods of time in U.S. history.  These include the Victorian Era, the Arts and Crafts Movement including American Bungalows, the Hispano Moresque Style – Byproduct of Spanish Colonial or Mediterranean-style Architecture, the Lean Era (a.k.a. Depression Years), the Utilitarian Era (a.k.a. Postwar Period) and finally, the Modern Era.  Within each time period, we take a look at how tiles were being made and have plenty of pictures to highlight the style.  The course then moves into predictions about  where the tile industry could go next.  Even though this course is part of the Finisher Apprentice program, it is beneficial for anyone who wants learn about the history of tile.










The History of Tile course is a travelogue through world history and the creation of tile. Photos courtesy of The Tile Heritage Foundation.

Trims and Profiles

The trims and profiles course is also good for anyone who is new to the industry.  The learner is taught about the different types of trims and profiles, where each is used, and why.  It also reviews the different types of official names and job site names for these products.  For example, I learned that a “cove base” is well known as a “sanitary base” and there’s a need for this product to meet health department or building code regulations.  Once all of the ceramic trims and metal or plastic profiles are introduced, the course moves into how to make your own bullnose or trim pieces.

Trims and Profiles reviews the various ways to finish a tile installation, and how to make your own bullnose or trim pieces. Photos courtesy of Schluter and Crossville.  

Coverings courses

If you are planning a trip to Coverings this year, Mark Heinlein and I will be presenting a course on using online education and apprenticeship to improve company performance on Wednesday April 5th at 3:00 pm.  If you haven’t seen NTCA University, this is your chance to see how to use it and the courses that are currently available.

Remember, you can purchase your all subscription access by visiting the NTCA store.  Make sure that you are logged in to get your introductory pricing.  If you purchase this subscription, you will have access to all of the learning content, including anything new that is created through December 31, 2017.  If you have any questions, please feel free to contact me at [email protected] or 770-366-2566.

Member Spotlight – Gudbrandsson Tile & Stone – March 2017

GUD Vibrations – Manitoba tilesetter discovers his professional passion on the cusp of fatherhood

NTCA is an international association, and as such, in this issue, we present to you a member from Manitoba, Canada – Gudbrandsson Tile & Stone (, which installs tile and stone in mostly residential renovations and new homes, with occasional commercial hand-crafted specialty projects.

Brandur Gudbrandsson joined NTCA in 2016 due to the influence of fellow Tile Geeks tilesetters he admired.

Brandur Gudbrandsson was working as a trucker until the discovery that he would soon be dad to a daughter helped bring his passion into laser-like focus. At the time, he learned his best friend for 17 years was also having a child. That became the impetus to start in the tile and flooring industry, with Gudbrandsson’s only knowledge stemming from “being in and out of the trade for 10 years.”

Gudbrandsson quit driving and began buying tiling tool until he hit a bump in the road. “Ironically, my buddy of 17 years did not want to continue after one month of work and we found out our sixth great grandfathers were half brothers,” he said. “He became a professional trucker; I became a professional tilesetter.”

Brandur Gudbrandsson (far left) and a group of NTCA members and Tile Geeks at the NTCA booth during Coverings 2016 in Chicago.

Gudbrandsson’s grandfather said, “Stand still, nothing accomplished.” Standing still wasn’t good enough for Gudbrandsson. “ When I had to take the leap of being a dad, I told myself follow my passion and I will succeed,” he said. “I thank my daughter for where I am today — and my grandfather’s hard working roots. Everything I do — on a job or in the industry — has my family name on it. It signifies quality.”

Gudbrandsson joined NTCA in 2016 due to the influence of fellow Tile Geeks tilesetters he admired. “I believe the industry is being re-pioneered today, and I came into the industry at the best time,” he said, adding that he wants to “be involved with the industry as deeply I can get.”

Gudbrandsson said, “The greatest aspect of becoming a NTCA member is the support and networking from so many GUD people. I had the pleasure of meeting many in Chicago at Coverings

Gudbrandsson drove from Manitoba to Chicago in 2016 to attend Coverings; Dave Karp gave him a warm welcome.

2016. It was a GUD drive; Dave Karp owner of Tile Fusion was the first to greet me on the journey from Manitoba.”

He continued, saying, “It is a GUD satisfaction to be a part of an ancient art. It gives me great joy to see more people involved every day. The networking is very GUD locally and abroad. Becoming a Tile Geeks member led me to create Tilesetter Canada Facebook group for more regional connections. I see now setters from Canada helping each other finding work, becoming friends and help troubleshooting problems, or connecting with a tile company representative.

“Seeing the tile community through social media using the word GUD is also flattering,” he added. “Perseverance, consistency, details –meeting anyone with the same passion is always a pleasure.”

Riding Shotgun – Business Tip – March 2017

by Connie Heinlein

Connie Heinlein is the wife of NTCA technical trainer Mark Heinlein. She accompanies him all over the country and assists him as he gives workshops, participates in trade shows and conferences (many of Mark’s great photo documentation of his workshops, and people and places he visits is due to Connie’s photography skills). Here she shares her perspective on the value of NTCA, as she, “rides shotgun” with Mark. Follow her and Mark’s adventures on Facebook. – Lesley Goddin

Connie Heinlein (center) at the Mechanicsburg, Pa., workshop earlier this year at Daltile. With Connie are: (l. to r.): Scott Carothers (CTEF/NTCA); Todd DeKorte , MAPEI; Tim Phoenix , Daltile; and Dale Kreider.

I spend a lot of time riding in the passenger seat of the NTCA van, traveling all over the country to workshops and trade shows with my husband Mark. Much of that time I watch out the window as the country passes by—rolling hills in Pennsylvania, corn fields in Iowa, mountain vistas in Montana, farms with red barns everywhere, and the ubiquitous truck stops. Sometimes I read or listen to the radio. I never sleep because I don’t want to miss anything.

Most of the time I can’t help but listen in on Mark’s phone calls –what he refers to as the “Heinlein Hotline.” He gets a lot of calls from NTCA members and non-members alike. Most of them have a tile crisis. Some just want to chat. I am not always very interested in the conversations

Connie is a jill-of-all-trades; here she assists Mark in putting education sponsor logos on the new NTCA van she and Mark will be driving all over the country this year.

although I have learned a great deal in the past year about many aspects of the tile industry. I know all about mortar coverage and substrate preparation; I understand the basic complexities of a tile installation; I know that a tile job can fail for many reasons. Before I retired last year from my job teaching high school English, I never thought about mortar and grout and did not know the difference between NTCA and ANSI and TCNA.  But like I said, I’ve learned.  Tile is pretty interesting—maybe not as fascinating to me as literature and grammar, but pretty interesting. All that tile-related chemistry, physics, math and technology makes for some brainy stuff.

So anyway, I often listen in on Mark’s calls. — sometimes I even pipe in if it is someone I met along the way like a new member who joined at one of our workshops, or Mark’s boss with a  “Hi Jim.” Some of the calls are quick; an answer that Mark can rattle off easily. “What is the allowable lippage for such and such?” or “When is Coverings?” Most of the calls involve difficult situations and complicated questions. I remember one from a few months ago about a swimming pool deck that involved multiple calls and research.

Several months ago Mark got a message from a guy in Detroit who wanted to get some experience in setting tile.  He said he loves the tile business and hopes to become certified but needs an opportunity to learn more. The guy asked Mark if he knew of anyone who might help him. I thought that was a pretty big request, that perhaps Mark would diplomatically give the guy some direction toward training materials or an on-line program. I admit now that I underestimated my husband. He spent quite a lot of time with the guy—I now know his name is Alaa Waleed—and discovered what he was looking for and got a sense of his seriousness about learning.  Mark told Alaa that he would think on it, and see if he could come up with someone who might be interested in taking him on.

Alaa Waleed on the job. A connection with Mark Heinlein helped find him work, and Alaa was eager to learn about tile.

Some time passed. We went on a couple more trips. I forgot about Alaa Waleed. Mark did not. He had contacted his friend Phil Kozey about Al. Phil is a great guy, an excellent tile contractor, an NTCA State Ambassador, and fellow Michigander. Phil lives downstate. Mark and I live in the Upper Peninsula. We refer to any part of Michigan that lies below the Mackinac Bridge as downstate and we say it with a bit of sympathy, but oh well, not everyone can be a Yooper. But I digress.

Back to Phil Kozey of southern Michigan. I do not know all of the particulars about Mark’s communications with Phil. I think that during this time Al called and messaged Mark a few times and Mark called and messaged Phil. We all know how these things can go. Life is busy. And then out of the blue one day in March, we were driving on the Ohio turnpike and Mark’s phone chimed that he had a message. He asked me to open it. After all, I was just sitting in the passenger seat, riding shotgun, and staring out the window. The message was from Phil Kozey. Here is what Phil said:

Let me tell you about this guy that we spoke about that said he wanted to learn tile.  He is one of the nicest, eager-to-learn guys I have ever met in my life. After working his butt off for five days straight my

father handed him a paycheck. An hour later he pulls me to the side and hands me back the check and says I cannot accept this. It meant a lot to me that he was actually there to do nothing but learn and did not want to make any money, but I aggressively refused… and made him take the check.

He came in knowing absolutely nothing, but he is a quick learner and takes great direction and I really think it is going to be a long friendship between me and Al. I just wanted to say thanks for linking us up because it is an honor working with him. 

Of course, after reading that message, Mark immediately called Phil and I listened in on the conversation. Phil told Mark about how he eventually contacted Al and what a terrific person he is and how he is going to make an excellent tile guy.  It turned out to be a heartwarmingly human story about motivation, talent, kindness, and of course, tile. I don’t know the conclusion to this story yet. I do know that Phil and Al are now friends and that Al has a future in the tile business. I’m proud of Mark’s role in helping make this connection between two good men, and I am proud to be a small part of this NTCA world where stories like this happen all the time.

The Dean Smith Center wows with locker room renovation

Array of LATICRETE products installed by NTCA Five Star Contractor Neuse Tile Service expedites complex project

For the University of North Carolina Tar Heels men’s basketball team, the Dean Smith Center isn’t just an arena where games are played – the venue and its locker rooms are an important motivator for players and an invaluable tool for impressing potential recruits.

Since it was 15 years since the locker rooms were last updated, the elite team decided it was time for an upgrade that matched its reputation as a breeding ground for many of the sport’s top athletes, including NBA legend Michael Jordan.

The goal of the $5-million locker room renovation was not only to modernize the space, but also to rival those found in top NCAA programs, serving as a point of pride for the athletes as one of the best off-the-court spaces in college basketball.

In addition to expected upgrades to showers and toilets, the extensive renovation also included spaces that maximized the locker room’s use, including a nutrition and beverage station, therapy areas, media room for press conferences and interviews, team meeting and video space, a players’ lounge and separate locker areas for players, coaches and staff.

“With so many wet areas and surfaces that require frequent cleaning, tile installations were a prominent part of the overall project,” said Nyle Wadford, president of Neuse Tile Service, the NTCA Five-Star Contractor chosen for the project. “It was crucial for our team to be able to rely on the performance of LATICRETE® products when dealing with so many different installations on such a multi-faceted project.”

The Challenge

High Profile – There are few college basketball programs in the country with a reputation as prestigious as UNC, which has earned a top 10 national ranking year after year and produced many NBA athletes. Neuse Tile Service knew from the outset that this facility would double as a recruiting tool and a functioning facility for the basketball team, so the space needed to “wow” visitors while withstanding heavy everyday use.

Tile Availability Due to changes in preferences and long lead times on the materials that were originally specified, the project experienced multiple tile changes. Neuse Tile was called upon to find new sources for products with narrow variance. With each change, hard samples had to be sent out of state for approval from the design team and project committee. Ultimately, Neuse Tile’s relationship with local vendors proved to be crucial in the attempt to provide options that were within design specifications, readily available in the right quantities and the right color of Carolina blue.

LATICRETE HYDRO BAN was carefully applied to make sure the shower updates are long-lasting.

Tight Timeframe – The entire renovation was limited to just seven months, with an expected completion prior to the start of the 2016 college basketball season. Neuse Tile was only given two months to complete its part in an effort to allot enough time for the other trades to complete theirs as well. Ultimately, the schedule was compressed even more due to the demanding materials selection and approval process, resulting in final completion just hours before the grand opening gala.

A LATICRETE solution

Nearly 6,000 sq. ft. (557 m2) of large-format, glass and mosaic tiles were installed by Neuse Tile during the locker room renovation, each with associated waterproofing and substrate preparation.

LATICRETE products were used in conjunction with various TCNA installation methods to resolve many issues during the construction process. Products were chosen not only for their specific performance – such as LATICRETE 4-XLT being the ideal large-and-heavy tile mortar solution due to its non-sag performance and its shear bond strength – but for how well they worked cohesively to solve the problems at hand. Due to the combination of LATICRETE products chosen, Neuse Tile Service was able to guarantee work done would prove durable and require low maintenance for years to come.

Thanks to the rapid-curing formula of the HYDRO BAN® waterproofing product, multiple phases of the work were able to proceed simultaneously with careful coordination. Completed and often concurrent installations included mud-set installations, the use of various membranes, thin-set installations on concrete, large-format glass wall tile, extensive waterproofing, the use of linear drains and preformed niches, and tile installations in the construction of therapy pools. TCNA Methods F113-16, F112-16, F125-Full-16, F115-16, W2021-16, W243-16, W245-16, B420-16 and P602-16 were used.

The array of solutions provided by LATICRETE products and technology proved to be a perfect match for this technically diverse and difficult assembly of installations. Since multiple tile types were used throughout the project, almost every area required different products for installation. Installations ranged from very simple – such as adhering the tile to drywall – to the much more difficult mud-set tile in the pools.

Unique uses of conventional products were also creatively applied to allow design concepts to come to life from sketches and ideas. Multiple uses of decorative and functional profile edgings for everything from floor transitions, bullnose substitutes, mirror trims and channels for low-voltage lighting, added to the creativity this project required, but also to its complexity.


“Our many years of experience, technical knowledge and craftsmanship as a NTCA Five Star Contractor were called upon during this process,” Wadford added. “That, and a great deal of collaboration from the entire construction team, as well as the product solutions from LATICRETE, made this tightly scheduled project a huge success,” he said.

The UNC’s men’s basketball locker room is now considered among the best locker rooms nationwide and continues to be a talking point for the school at large.

The hot and cold spa pools were installed with LATICRETE HYDRO BAN, 3701 Fortified Mortar & 254 Platinum, SPECTRALOCK Grout and LATASIL caulk. The stone on the walls over the spas was installed with LATICRETE 4-XLT. Photo credit – Jim Sink Photography
