The i4F system provides multiple flooring installation technologies, including drop-lock, click, glue-down, and loose-lay options. Installation procedures vary depending on the specific technology and product. Proper subfloor preparation, temperature control, and tool usage are critical for successful installation. This article details installation instructions and considerations based on available documentation.
i4F Drop-Lock Technology Overview
i4F Drop-Lock Technologies combine two technologies to create a strong and high-performing floor. Installation instructions are available for various applications, including 4-sided tiles and herringbone patterns. The system utilizes alignment planks to facilitate a faster installation process. The core principle involves angling and dropping planks together, ensuring a secure connection.
Installation Process with Alignment Planks
The installation process commonly utilizes two planks as an alignment guide, designated as plank 0 and planks 1 and 2. Plank 0 should be centered across planks 1 and 2. A brick-laying pattern, where planks are staggered, is recommended. The minimum length of a plank should be at least 30cm (11.8 inches).
The following tools are typically required: spacers, a pencil, a tape measure, a level, a cutter knife, and a hard PVC mallet. Plinths are optional. An underlayment should be placed before installation if it is not pre-attached to the flooring panels.
The initial step involves aligning the first two rows. A full plank (plank 0) serves as an alignment guide and is placed against the wall without using spacers initially. A second full-length plank is then angled into the middle of the long side of plank 0 and dropped into place, ensuring no gaps are present. A third full-length plank is angled into plank 0, and then slid until its short side contacts the short side of plank 1.
Plank Connection Techniques
To connect subsequent planks, the short end of a plank is placed at an angle against the previously installed plank and folded down completely. This process is repeated for each plank. Distances should be maintained between the product and the wall, typically between 1/8” to 1/4”, depending on the installation area size. These spaces can be covered with base molding. At doorways, a supporter should be placed after installation, or pressure-sensitive adhesives can be used up to 19.5” from the edges.
The maximum area that can be installed without an expansion joint is 32.5 ft x 32.5 ft. Areas where heavy objects, such as furniture and refrigerators, are expected to move after installation require installation with pressure-sensitive adhesive. Planks should be cut vertically to prevent curling after installation.
Disassembly and Repair
Panels can be disassembled by angling the short sides up vertically. To release a row, carefully lift it up and then fold up the entire long side. The process can be reversed to reassemble the panels. The documentation provides guidance on repairing a single plank within the i4F Drop-Lock system, though specific repair procedures are not detailed.
Subfloor Preparation
Proper subfloor preparation is essential for a successful installation. The subfloor must be clean, dry, smooth, structurally sound, and free of paint, varnish, existing adhesives, oil, grease, solvents, and other extraneous material. The moisture content of the subfloor must be less than 4.5%, and any cracks should be properly treated. Lightweight concrete should be avoided unless reinforced. Wood subfloors should be constructed with a double-layer system, with a finished thickness of at least 1 inch and 18 inches of well-ventilated air space underneath. Crawl spaces should be insulated and protected with a vapor barrier. Caution should be exercised when installing over nail holes or uneven places.
Temperature and Humidity Considerations
When installing LLP (likely Loose Lay Product), the product should be maintained within a temperature range of 64°F to 77°F. If the temperature is below 64°F, an appropriate thickness spacer should be used. Conversely, if the temperature is above 77°F, the tiles should be installed tightly together.
For glue-down Corelogic Patriot Plank LVT, the floor must be properly cured and dried to less than 4.5% moisture content, which may take 30 days in a new building at 68°F and 65% humidity. Tiles and adhesives should be conditioned at the site for at least 24 hours at 64-72°F before installation, and heating should be stopped at least 3 hours prior to installation.
Adhesive Application and Precautions
When installing glue-down LVT, it is important to secure the required number of tiles from the same lot to prevent color differences. Installation should be completed after all other construction work is finished, or installed products should be protected with a cover. A can of adhesive should be turned upside down for 20 minutes and shaken well before application. An adequate amount of adhesive should be applied evenly to a portion of the area.
Specific Installation Scenarios
The documentation details specific installation considerations for various scenarios:
- Around Pipes: Drill holes two times larger than the pipe diameter. Remove a piece of the panel with a utility knife, placing it on one side of the pipes and the removed piece on the other.
- Vertical Locking Part Removal: Remove the vertical locking part of the strip with a chisel, apply glue, and push the panels horizontally together.
- Wall Spacing: Place spacers between the last board and the wall.
Additional i4F Technologies and Resources
i4F offers resources including installation instructions for i4F HerringB/ONE, laminate installation using alignment planks (i-Click4U), 4-sided tiles, and herringbone patterns. Brochures are available for ClikDek, CeraGrout, AquaProtect, and Be-Lite®. Instructional videos cover topics such as i4F ClikDek, Click4UPro-Angle Out, i4F CeraGrout, successful i4F drop-lock installation, i4F AquaProtect, repairing a single plank, installing and disassembling vinyl floors, and demonstrations for Multi Layer PVC Board and 3L TripleLock systems. Animations illustrate the installation of Walls and Ceilings, as well as Liquid Laminate Technology “Light”.
Conclusion
The i4F system offers a range of flooring installation technologies, each with specific requirements and procedures. Successful installation relies on careful subfloor preparation, adherence to temperature and humidity guidelines, proper tool usage, and following the detailed instructions provided for each product and application. The availability of resources such as installation guides, brochures, and instructional videos supports a successful outcome.
