For U.S. homeowners and professionals seeking to install high-quality flooring, CALI offers a range of durable and aesthetically pleasing options, including bamboo and luxury vinyl planks (LVP). The installation process for these materials requires careful preparation, adherence to specific techniques, and an understanding of environmental and structural considerations. This article provides a detailed overview of the installation procedures for both CALI Bamboo and CALI Vinyl Longboards, based on the manufacturer’s official installation guides and technical specifications.
Overview of CALI Flooring Products
CALI Bamboo flooring is crafted from dense bamboo canes that undergo a rigorous boiling and drying process to achieve a moisture content of 6-8%. This treatment enhances the material's hardness and resilience, making it one of the most durable natural flooring options available. CALI Bamboo can be installed using three primary methods: floating, gluing, or nailing. Each method has specific requirements, particularly concerning subfloor preparation, acclimation, and environmental conditions.
CALI Vinyl Longboards, on the other hand, are part of the luxury vinyl plank (LVP) category and are designed for floating installations. These planks are manufactured with a waterproof core, making them suitable for a wide range of environments, including kitchens and bathrooms. However, despite their water-resistant properties, CALI Vinyl Longboards require the use of a moisture barrier when installed over concrete subfloors.
Both products are engineered to be installed using click-lock mechanisms, which simplify the process and reduce the need for specialized tools. However, the installation of each material must be approached with specific considerations, particularly when dealing with radiant heating systems or expansive installation areas.
Installation Preparation and Subfloor Requirements
Before beginning any installation, it is essential to assess and prepare the subfloor. According to CALI’s official installation guides, the subfloor must be structurally sound, level, clean, and dry. The recommended subfloor types include CD Exposure 1 plywood, OSB Exposure 1 panels, underlayment-grade particleboard, concrete slabs, and existing wood or tile surfaces. For wood subfloors, secure fastening—nailing or screwing every 6 inches along joists—is advised to prevent squeaking and ensure stability.
Concrete subfloors require additional attention. While CALI Vinyl Longboards are waterproof, they are not considered a moisture barrier. As a result, the use of a 6-mil plastic moisture barrier is mandatory for concrete installations. This barrier prevents moisture migration, which could otherwise compromise the integrity of the flooring over time.
For both CALI Bamboo and CALI Vinyl Longboards, the subfloor must be level within 3/16 inch per 10-foot radius. If the surface is uneven, high spots can be sanded down, and low spots should be filled using a Portland-based leveling compound. The subfloor must also be free of debris, and any existing carpeting or soft surfaces must be removed before proceeding with installation.
Environmental conditions are another critical factor. The installation area should maintain a temperature between 65°F and 85°F and a relative humidity level between 20% and 80%. These conditions ensure that the flooring acclimates properly and minimizes the risk of expansion or contraction after installation.
Tools and Materials Required
To successfully install CALI Bamboo or CALI Vinyl Longboards, several tools and materials are necessary. The recommended tools include:
- Tape measure for accurate room dimensions
- Chalk line to establish straight installation lines
- Utility knife for scoring and snapping end cuts
- Rubber mallet for gentle tapping
- Miter saw or table saw for rip cuts
- Pencil for marking
- 1/4” spacers to maintain expansion gaps
- Double-sided prybar for adjusting planks
- Tapping block for securing planks without damage
In addition to these tools, specific materials are required:
- Moisture barrier (6-mil plastic) for concrete subfloors
- Expansion molding (reducers, T-moldings, baseboards, quarter rounds, thresholds)
- Stair parts (stair nosing, treads, risers)
- Additional planks (an extra 5% to account for cutting waste and grading)
It is also important to note that CALI recommends using the score-and-snap method for end cuts with a utility knife. However, for rip cuts—cuts along the length of the plank—it is advisable to use a table saw or miter saw for precision.
Installation Steps for CALI Bamboo Flooring
The installation of CALI Bamboo flooring can be performed using either a floating, gluing, or nailing method. However, the gluing method requires the use of a high-quality adhesive that is compatible with bamboo flooring. The adhesive must be applied in accordance with the manufacturer’s instructions, and a moisture barrier should be installed over concrete substrates.
Acclimation: Before installation, the bamboo planks must be acclimated to the environment. This involves allowing the material to sit in the installation area for at least 48 hours to adjust to the temperature and humidity levels.
Subfloor Preparation: Ensure the subfloor is clean, level, and dry. Install a moisture barrier if the subfloor is concrete.
Laying the First Row:
- Begin with a plank cut to at least 8 inches in length.
- Position the plank with the exposed lip facing the installer.
- Stagger the first two rows in a brick-laid pattern to ensure proper engagement.
- Use a tapping block to gently secure the planks in place.
Continuing the Installation:
- Work in a consistent direction, ensuring each plank is properly engaged with the previous one.
- Use a tapping block and rubber mallet to press the planks together.
- Maintain a 1/4-inch expansion gap around the perimeter and all fixed objects.
Finishing Touches:
- Install expansion moldings to cover the gaps.
- If the installation area exceeds 80 feet in either direction, use transition pieces to separate sections.
Post-Installation Care:
- Avoid exposing the flooring to extreme temperatures or humidity.
- Regularly sweep or vacuum to maintain cleanliness.
- Use felt pads under furniture to prevent scratches.
Installation Steps for CALI Vinyl Longboards
CALI Vinyl Longboards are designed for floating installations and are not compatible with gluing or nailing methods. The installation process is relatively straightforward and can be completed without power tools, making it ideal for DIY enthusiasts.
Acclimation: The flooring must be acclimated to the environment for at least 48 hours. If the room is equipped with a radiant heating system, the system must be turned on and in operation for at least 3 days before installation. The temperature should be reduced to 65°F and maintained for 24 hours prior to installation.
Subfloor Preparation:
- Ensure the subfloor is level, clean, and dry.
- Install a 6-mil plastic moisture barrier over concrete subfloors.
- Remove any existing carpeting or soft surfaces.
- Secure wood subfloors by nailing or screwing every 6 inches along joists.

Radiant Heating Considerations
When installing CALI Vinyl Longboards over a radiant heating system, several additional precautions must be taken. The floating installation method is the only method recommended for use with radiant heat systems. Before installation, the system must be turned on and in operation for at least 3 days. The flooring must then be acclimated over the radiant heat system with the system turned on throughout the acclimation period. After installation, the system should be gradually brought back to normal operating temperature over a period of 4-5 days.
It is important to note that the floor should never be heated above 85°F. Consult with the radiant heating system manufacturer to ensure the maximum temperature is properly limited. Additionally, rugs placed over radiant heated flooring can increase the surface temperature by 3°-5°F, so this should be considered when planning room layout.
When turning off the radiant heating system, it must be done gradually at a rate of 1.5°F per day. Sudden shutdowns can cause temperature fluctuations that may affect the flooring's performance. The relative humidity must also be maintained between 20% and 80% to prevent expansion or contraction issues.
Warranty and Liability Considerations
According to CALI’s official documentation, the installer or homeowner assumes full responsibility for ensuring that the installation site, subfloor, and environmental conditions are suitable for the flooring. CALI does not warrant against failures resulting from subfloor issues, job site damage, or environmental deficiencies after installation. Additionally, the company does not guarantee the quality of the installer’s work or the success of a particular installation performed by an individual.
It is the responsibility of the installer or homeowner to inspect all flooring before installation. Planks with visible defects that are noticeable from a standing position should be cut off or not used, as their use constitutes acceptance of the material. If more than 5% of the material is unusable due to manufacturing defects, installation should be halted immediately, and the distributor or retailer should be contacted for a replacement or refund.
