The Mohawk PureTech flooring system is a durable, eco-friendly vinyl plank designed for residential use. With its rigid core construction, zero PVC content, and advanced WetProtect® technology, PureTech is marketed as a user-friendly and resilient flooring solution. However, proper installation is essential to ensure optimal performance, longevity, and warranty compliance. This guide provides a detailed, step-by-step overview of the installation process for Mohawk PureTech, drawing exclusively from the official specifications and instructions provided in the manufacturer’s documentation.
Overview of Mohawk PureTech Vinyl Plank
Mohawk PureTech vinyl planks are designed to mimic the appearance of natural hardwood with embossed textures and GenuEdge bevels. The product is composed of 70% total recycled content and is PVC-free, making it a sustainable and environmentally conscious option for homeowners. It is installed using the Uniclic® system, which eliminates the need for adhesives and allows for a floating floor installation.
The planks are available in a range of wood-inspired finishes and feature a 20-mil wear layer for enhanced durability. They are marketed as scratch-resistant and stain-protected, with a Pet Scratch Warranty and WetProtect® surface and subfloor warranty. PureTech is suitable for use in climate-controlled indoor environments and can be installed above, at, or below grade. However, specific site and subfloor preparation requirements must be met to ensure a successful installation.
Pre-Installation Requirements
Before beginning the installation of Mohawk PureTech, several site and subfloor conditions must be verified to ensure compatibility and compliance with the manufacturer’s recommendations. These requirements are outlined in the official installation guide and must be followed to maintain warranty coverage.
Subfloor Conditions
The subfloor must be clean, dry, and structurally secure. It must meet local building code requirements and be free of any damage caused by moisture or structural issues. Specific moisture content limits are outlined for different types of subfloors:
- Concrete subfloors: Must pass a calcium chloride moisture test (ASTM F1869) with values ≤ 5 lbs/1000ft²/24 hrs or an in-situ relative humidity (RH) test (ASTM F2170) with values < 80% RH.
- Wood subfloors: Must have a moisture content ≤ 12%.
If the subfloor does not meet these specifications, it should be addressed before proceeding with installation. A moisture test is strongly recommended for all subfloors, particularly concrete, to determine the presence of high moisture levels.
Environmental Conditions
PureTech is designed for use in climate-controlled indoor environments with a relative humidity range of 35% to 65% and temperature range of 60°F to 85°F. It must not be installed over any floor with a sump pump or in a room with a floor drain. The flooring is not suitable for outdoor or high-moisture areas such as bathrooms or basements with standing water.
Floor Movement and Expansion
PureTech is installed as a floating floor, which means it is not glued, nailed, or otherwise fixed to the subfloor. To accommodate natural floor movement, the manufacturer recommends the use of T-moldings in the following situations:
- Doorways less than 32 inches (0.81m)
- Doorways where the installation changes direction
- Rooms that are 50 feet (15.24m) or larger in length or width
T-moldings help to prevent buckling and allow for proper expansion. It is important to ensure that the floor is not constrained by glue, nails, screws, or other fixed obstructions, as this can lead to warping or damage.
Installation Process
The installation of Mohawk PureTech uses the Uniclic® system, which allows planks to be clicked together without the use of adhesives. The process involves several steps, including site preparation, acclimation, layout planning, and final installation.
Step 1: Site and Material Preparation
Before installing PureTech, the following tasks must be completed:
- Remove all existing flooring, including carpet, padding, and wood flooring installed over concrete. Do not remove products unless they are asbestos-free.
- Ensure that the subfloor is clean, dry, and structurally sound.
- Remove all furniture, appliances, and interior mats from the room.
- Acclimatize the PureTech planks to the installation environment for a minimum of 48 hours to prevent warping or buckling.
Proper acclimation is crucial to ensure that the planks adjust to the temperature and humidity of the room before installation. Failure to do so may result in premature damage or warranty voidance.
Step 2: Layout Planning
To ensure a seamless and professional installation, it is recommended to plan the layout before beginning. The following considerations should be made:
- Start the installation with a full plank in the longest wall of the room.
- Use a chalk line or laser level to mark the starting point and ensure straight lines.
- Leave a 1/4-inch expansion gap along all walls and around obstructions to allow for natural floor movement.
- Use T-moldings in doorways and large rooms as needed.
By following these guidelines, the installation will be more efficient and visually appealing.
Step 3: Installing the First Row
The installation process begins by placing the first row of planks along the starting line, ensuring that the 1/4-inch expansion gap is maintained. The planks are clicked together using the Uniclic® system, which allows for a secure and stable fit without the need for adhesives. It is important to apply even pressure and avoid forcing the planks together to prevent damage.
Once the first row is installed, the planks should be checked for alignment and fit. Any visible defects or irregularities should be addressed before proceeding.
Step 4: Continuing the Installation
After the first row is in place, the installation continues by working across the room. Each row is locked into place using the Uniclic® system, and care should be taken to maintain the expansion gap along the walls and around obstructions. It is recommended to stagger the joints between rows by at least one-third of the plank length to ensure a uniform and visually appealing appearance.
The manufacturer recommends working in small sections to maintain control and prevent the planks from shifting during installation. Once a section is complete, it can be moved and repositioned as needed.
Step 5: Finishing Touches
Once the entire floor is installed, the final step is to trim and fit the planks around doorways, corners, and other obstructions. This can be done using a straight edge and a utility knife or a miter saw. It is important to maintain the 1/4-inch expansion gap during this process to allow for proper movement.
T-moldings and expansion molding should be installed in doorways and along the perimeter of the room to cover the expansion gap and provide a finished appearance. These components help to protect the floor from buckling and ensure a clean, professional look.
Post-Installation Care and Maintenance
After installation, proper care and maintenance are essential to preserve the appearance and performance of Mohawk PureTech. The manufacturer provides specific guidelines for cleaning, spill removal, and steam mopping to ensure that the floor remains in optimal condition.
Cleaning and Spill Removal
- Remove spills promptly using a clean, dry or damp cloth.
- For stubborn stains, use a microfiber cloth with a Mohawk-recommended cleaner and work from the outside of the stain toward the center.
- Do not allow liquids to remain on the surface of the flooring for extended periods, as this can lead to spotting or damage.
- Avoid using oil soaps, wax, detergents, abrasive cleaners, polishes, surfactants, or other household products that can damage the floor.
Steam Mopping
- A residential steam mop may be used, but only with a microfiber pad and not directly on the floor.
- Set the steam mop to the appropriate setting for PureTech floors or to the lowest setting.
- Steam mop in the length direction of the planks only.
Tools and Products to Avoid
- Vacuums with beater bars or power rotary brushes should never be used on PureTech flooring.
- Power scrubbers are not recommended for cleaning the floor.
By following these care and maintenance guidelines, homeowners can ensure that their PureTech flooring remains in excellent condition for years to come.
