Go to any installer who’s been in the industry for a while and ask them the biggest issue that can lead to a flooring failure. Chances are, they’ll tell you the culprit is moisture. For this article, the first of our two-part look at moisture mitigation, we asked manufacturers to share projects that incorporated moisture mitigation in their planning and execution. Next month we’ll speak directly with contractors, discussing their personal experiences in encountering and dealing with moisture problems on the jobsite.

Bavette’s Steakhouse at Park MGM Resort, Las Vegas 

As part of the prize for winning Bostik’s The Art of Hardwood Flooring Design contest in 2017, interior designer Jennifer Sheets had her interlocking, geometric design installed at Bavette’s Steakhouse at Park MGM Resort in Las Vegas. The steakhouse also required leveling of the existing concrete slab to accept the custom hardwood flooring installation.

Bostik products used on the project included UltraSet Singlestep2 and UltraGrip adhesives, SL-175 self-leveling underlayment and Universal Primer Pro. The adhesives feature AXIOS Tri-Linking Polymer Control Spacers which according to the company offer “tenacious bond strength, superior moisture control properties, and ease of installation and clean up.”

Sheets stated that her award-winning design was inspired by the Art Noir movement. “The pattern depicts an array of interchanging shapes that harmoniously fit within a symmetrical medallion. I created my Array design to complement, as well as enhance, the herringbone featured floors throughout the main restaurant space.”

Oshkosh Designs translated the design into hardwood pieces ready to install. According to President/CEO Brenda Kubasta, “We were up to the challenge of producing world-class wood flooring that is in synch with the overall theme of the restaurant. We are so proud to be featuring our premium craftsmanship for this ultra-high visibility, hospitality space.”

MasterCraft Floors, which is well-known for delivering on complex installation projects throughout Las Vegas, was in charge of the restaurant’s floor installation. Garrett Ulfig, West Coast operations manager, stated, “In the past, we’ve worked successfully with MGM Resorts. We’re grateful they acknowledge the quality of our work, and we’re equally pleased that Bostik is so involved in this project.”

Eagle Bay Hardwood Flooring, the exclusive brand produced by Delta Hardwood Flooring of Boonville, N.Y., was selected to provide wood flooring material for the remainder of the restaurant to complement the lobby work of Oshkosh Designs. The commercial-grade product met stringent specifications provided by the venue’s design firm, MBDS (Martin Brudnizki Design Studios) of London and New York.

Jacobs Medical Center, La Jolla, Calif

Construction specifications for the 500,000 sq. ft. Jacobs Medical Center in La Jolla, Calif., included a full complement of Custom Building Products’ flooring preparation products, waterproofing membranes, mortars and grouts for all 12 floors of the hospital. The medical facility—which focuses on complex procedures including brain surgery and marrow transplants—features an array of ceramic and glass tile in the patient bathrooms, public and staff areas, kitchen and cafeteria.

Along with ceramic and glass tile, Jacobs Medical Center also features several other floor coverings depending on the service needs of the area. Before installing vinyl sheet goods, all floors were prepped using a CustomTech calcium cement underlayment system which includes TechMVC Moisture Vapor and Alkalinity Barrier, TechPrime A Acrylic Primer and TechLevel 150 Self-Leveling Underlayment. The underlayment can be applied up to 1 1/2-in. deep in a single pour and, according to the company, “offers superior crack resistance and helps eliminate installation problems such as bond failure, crumbling and staining of resilient flooring.”

The general contractor for the project was Kitchell Contractors of Del Mar, Calif. Flooring prep and tile contractors included The Rouse Company, Rancho Dominguez, Calif.; Premier Tile & Marble, Gardena, Calif.; Inland Pacific Tile, San Bernardino, Calif.; Wirtz Tile and Stone, San Diego; and Howards Rug Company, San Diego.

For the tile installation, wet areas such as patient bathrooms and showers were treated with liquid-applied RedGard Waterproofing and Crack Prevention Membrane, which provides a continuous waterproofing barrier. A single coat of RedGard was also applied on both floated and concrete floors in dry tiled areas to provide crack isolation up to 1/8-in.

Large format tile—including 12- by 24-in. porcelain tile in patient bedrooms and along the floors, and 9- by 36- and 6- by 36-in. wood-look planks in the cafeteria—was installed using VersaBond-LFT Professional Large Format Tile Mortar. Kitchen quarry tile and 2-in. tile on shower floors were set with VersaBond Flex Thin-Set Mortar.

Three color schemes were chosen for patient bathrooms and nurses stations on different floors with 3/4- by 3/4-in. glass mosaic wall tile in green, blue and peach shades. Public restrooms feature 1/2- by 1/2-in. ceramic mosaics in dramatic black and white patterns. Wall tiles were installed using ProLite Premium Large Format Tile Mortar.

For environments that required chemical and stain resistance, CEG-Lite 100% Solids Commercial Epoxy Grout was specified for all floor and wall tiles. Movement joints in the project were treated with Custom’s Commercial 100% Silicone Sealant.

Paula’s School of Baton, Mount Joy, Pa

Paula McAdoo, owner of Paula’s School of Baton in Mount Joy, Pa., recently decided to have more than 1,700 sq. ft. of luxury vinyl plank installed in her renowned dance studio. The project, which was installed using DriTac 5900 MegaBond premium green resilient flooring adhesive, took less than three days to complete.

Her husband, Tim, has been in the flooring industry for more than 40 years, including installation, manufacturing, research and development, and instruction. He is currently the installation specialist for JJ Haines, one of the top flooring distributors in the country. When it came time to upgrade the floors, he had a decision to make on what adhesive he felt would perform the best.

Tim ultimately selected DriTac 5900 MegaBond, which offers moisture resistance up to 10 lbs. per the ASTM F1869 Calcium Chloride Method Test and 99% relative humidity per the ASTM F2170 Relative Humidity Test. Specially formulated to help minimize vinyl plank shrinkage, the pressure-sensitive adhesive offers high initial tack, high shear strength, and excellent bond strength.

Regarding his decision, Tim said, “I needed a premium-grade, eco-friendly flooring adhesive that offers superior moisture-resistant capabilities.” Additionally, both Tim and Paula wanted an adhesive that featured no VOCs or solvents and third-party certification from the Carpet and Rug Institute (CRI) for excellent indoor air quality.

Tim’s crew of four handled the installation of 7- by 48-in., 20mm-thick luxury vinyl planks, which required approximately 10 hours of work and a little over two days to complete. The 5900 MegaBond adhesive was troweled on over a 4mm layer of sound-reducing underlayment, allowed to dry to the touch, and resulted in a fantastic bond without any slippage, Tim stated.
