Introduction
Cali Flooring offers a range of durable, aesthetically pleasing flooring solutions, including engineered hardwood, luxury vinyl planks (LVP), and bamboo flooring. Whether installed in residential or commercial settings, proper installation is critical to ensuring long-term performance and durability. The manufacturer provides detailed installation instructions to guide users through preparation, adhesive and fastening techniques, and finishing steps. These instructions emphasize the importance of adhering to industry standards, particularly those outlined by the National Wood Flooring Association (NWFA). This article compiles key installation guidelines from official documentation, focusing on preparation, subfloor requirements, and best practices for different installation methods. By following these instructions, users can achieve a seamless, professional finish that meets the product's warranty and performance expectations.
Preparation and Pre-Installation Requirements
Subfloor Evaluation and Testing
Before beginning the installation of Cali Flooring products, it is essential to evaluate the subfloor for structural integrity, flatness, and moisture content. All subfloors must be clean, dry, and structurally sound. The manufacturer specifies that subfloor flatness is particularly critical for floating floor installations, requiring a tolerance of 1/8" over a 10-foot radius. For glued-down or nail/staple-down installations, subfloors must be tested for moisture content and must conform to the normal moisture levels typical for the region.
Moisture testing should be conducted according to the procedures outlined in the National Wood Flooring Association (NWFA) installation guidelines. If the space beneath the subfloor is not conditioned (i.e., not climate-controlled), a Class II vapor retarder is required. This includes either a liquid-applied vapor barrier or a 6 mil polyethylene film, provided the underlayment does not already contain a sufficient barrier. The application of any vapor retarder must follow the manufacturer’s instructions, and proper drying time must be observed before proceeding with the flooring installation.
Material Inspection and Handling
Prior to installation, all materials should be carefully inspected for visible defects such as warping, discoloration, or damage. The manufacturer explicitly states that materials installed with visible flaws are not covered under the warranty. It is also crucial to ensure that the correct color and style are selected, as no claims will be accepted for color discrepancies once the flooring is installed.
To achieve a uniform appearance, it is recommended to open and use multiple cartons at once. This helps in blending the color and grain patterns across the floor. Boards should be staggered to avoid continuous joints, with a minimum 6-inch gap between end joints on adjacent rows. Proper staggering enhances the visual appeal and structural stability of the installed floor.
Workspace and Installation Layout
The installation should begin parallel to the longest unbroken wall, ideally an exterior wall. However, users must ensure that all walls are straight and plumb before starting. A working line should be snapped parallel to the starting wall to guide the layout. This line helps maintain alignment and ensures consistent spacing around vertical obstructions.
An expansion space must be left around the perimeter of the room, at least equal to the thickness of the flooring. For floating installations, a minimum 1/2-inch expansion space is required regardless of the material's thickness. This space allows for natural expansion and contraction due to environmental changes and prevents buckling or warping.
Installation Methods and Guidelines
Glue-Down Installation
Glue-down installation is a recommended method for Cali Flooring products, especially when a more permanent and stable installation is desired. The following steps and guidelines are provided:
Working Line and Adhesive Application: A working line should be snapped parallel to the starting wall. A straight edge is then secured along this line to prevent board misalignment during adhesive application. Urethane adhesive should be used, as water-based adhesives are not recommended for this product. The adhesive should be applied using a trowel as recommended by the glue manufacturer.
Expansion Space and Vertical Obstructions: A minimum expansion space of 1/2 inch should be maintained around all vertical obstructions. This includes doorways, baseboards, and other fixed objects. The working line should be adjusted to account for these spaces before spreading adhesive.
Adhesive Residue and Cleanup: After installation, all adhesive residue must be thoroughly removed from the floor. Solvents should not be applied directly to the flooring surface. Any area wiped with a solvent rag must be re-wiped with a damp cloth to remove any residual solvent.
Floating Installation
Floating installation is another viable option for Cali Flooring, particularly for engineered hardwood and luxury vinyl planks. This method does not require adhesives or fasteners, allowing the floor to "float" over the subfloor. The following guidelines are critical for a successful floating installation:
Subfloor Flatness and Underlayment: A flat subfloor is essential for a floating floor, with a tolerance of 1/8 inch over a 10-foot radius. The underlayment used must not exceed 2 mm in thickness and should be high-density. If the subfloor is concrete, a 6 mil polyethylene film may be required if the underlayment does not already contain it. However, users should avoid taping seams of polyethylene over wood subfloors.
Expansion Space and Transitions: A minimum expansion space of 1/2 inch should be left at all vertical surfaces. Transitions are recommended at doorways or openings 36 inches or less. The maximum span without a transition is 40 feet in any direction. Failure to install transitions at appropriate intervals may result in buckling or separation at doorways.
Adhesive and Glue-Assist Method: For products wider than 5 inches, the manufacturer recommends using a glue-assist method when performing nail or staple-down installation. This helps prevent gaps and ensures a more secure fit. Users should refer to the NWFA Technical Manual for detailed instructions on this method.
Nail or Staple-Down Installation
For wider products, the nail or staple-down method may be used. This method is suitable for engineered hardwood and is often recommended for more permanent installations. The following considerations apply:
Glue-Assist Method: When using a nail or staple-down method on products over 5 inches in width, a glue-assist method is recommended. This ensures a tighter fit and reduces the risk of gaps forming over time.
Vapor Retarder Considerations: If the installation is over a conditioned space that matches the climate of the living area above, a vapor retarder is not required. However, if the space below is not conditioned, a Class II vapor retarder compatible with the adhesive must be used. The application instructions for the vapor retarder must be followed carefully, and adequate drying time must be allowed before proceeding with the installation.
Subfloor Moisture Testing: Subfloor moisture testing is required, and the moisture content must fall within the normal range for the region. This helps prevent future issues such as warping or buckling.
Post-Installation Steps and Final Checks
Once the installation is complete, it is essential to perform a thorough inspection to ensure the floor is free from defects and meets the desired aesthetic and functional standards. The following steps should be taken:
Cleaning and Inspection: The installed floor should be thoroughly cleaned, swept, and vacuumed. Users should inspect the floor for scratches, gaps, or other imperfections. Any tape used to hold down floor protection should be removed carefully to avoid damaging the surface.
Use of the Floor: The manufacturer states that the new floor can be used immediately after installation for floating or nail/staple-down methods. However, if an adhesive is used, the floor can be used after 12–24 hours, depending on the adhesive’s cure time. Users must ensure that the adhesive is fully cured before subjecting the floor to heavy use or foot traffic.
Final Cleanup and Warranty Considerations: All adhesive residue must be removed from the job site before leaving. Users should avoid using solvents directly on the flooring surface. Any area wiped with a solvent rag should be re-wiped with a damp cloth to eliminate any residual solvent. Failure to properly clean the floor may void the warranty or lead to long-term performance issues.
Transition and Expansion Management: Transitions should be installed at doorways or openings 36 inches or less, and the maximum span without a transition is 40 feet in any direction. The use of T-molds or other transition strips is recommended to prevent buckling or separation at doorways.
