Karndean flooring offers a range of luxury vinyl tile (LVT) and plank options suitable for residential and commercial applications. Installation methods vary depending on the product line, with options including glue-down, click-lock, and looselay. Proper installation is crucial to ensure the flooring’s performance, longevity, and waterproof properties. This article details the installation procedures for each method, based on official Karndean documentation.
Understanding Karndean Flooring Types and Subfloor Preparation
Karndean flooring is designed as a floating floor with acoustic and thermal properties, and is resistant to water damage when properly installed. However, it is not suitable for outdoor use or continually wet environments. It can be used in bathrooms, kitchens, and laundry rooms. Prior to installation, it is essential to verify the product’s suitability for the intended application.
Regardless of the installation method, subfloor preparation is paramount. The subfloor must be clean, dry, and level. Imperfections may require a leveling compound. For glue-down installations, a smooth subfloor is particularly important. The documentation specifies that a separate underlay is not normally recommended, but users should consult their floor covering supplier for specific details.
Glue-Down Installation Procedure
The glue-down method provides a strong, permanent flooring solution. This method requires specific materials and tools.
Required Materials and Tools:
- Karndean glue-down planks or tiles
- Vinyl flooring adhesive (specifically recommended by Karndean)
- Trowel for adhesive application
- Utility knife
- Measuring tape and straightedge
- Roller (with a weight between 50 and 100 pounds)
Installation Steps:
- Apply the recommended vinyl flooring adhesive to the subfloor using the appropriate trowel.
- Carefully position the Karndean planks or tiles onto the adhesive.
- Use a roller to firmly press the flooring into the adhesive, ensuring full contact.
- Wipe away any excess adhesive with a clean, damp cloth before it dries.
- Allow the adhesive to cure for 24 hours before walking on the floor.
Professional installation is recommended for optimal results with the glue-down method.
Click Lock Installation Procedure
Karndean click-lock flooring is designed for easier installation, utilizing a click-and-lock system that eliminates the need for adhesive. This method is well-suited for DIY enthusiasts.
Required Materials and Tools:
- Karndean click-lock planks
- Rubber mallet
- Spacers for expansion gaps
- Measuring tape and utility knife
- Underlay (optional, for cushioning or sound reduction)
Installation Steps:
- Prepare the subfloor, ensuring it is clean, dry, and level. If using underlay, install it first.
- Acclimate the planks to the room temperature for 24-48 hours before installation.
- Begin installation in a corner of the room, leaving a ¼-inch expansion gap between the flooring and the wall using spacers.
- Align the tongue of one plank with the groove of another at a slight angle, then press down to lock them together. Use a rubber mallet to ensure a tight fit.
- Continue installing row by row, staggering the planks for a natural appearance. Measure and cut planks as needed for edges.
- Once the floor is complete, remove the spacers and install baseboards or trim to cover the expansion gap.
Leaving an expansion gap is essential to accommodate the flooring’s natural expansion and contraction with temperature changes.
Looselay Installation Procedure
Karndean looselay flooring offers the simplest installation method. The planks utilize a specialized backing to grip the subfloor, often eliminating the need for adhesive.
Required Materials and Tools:
- Karndean looselay planks
- Utility knife
- Measuring tape
- Ruler or straightedge
- Roller (optional, for larger spaces)
Installation Steps:
- Prepare the subfloor, ensuring it is clean, smooth, and dry.
- Acclimate the planks to the room temperature for at least 24 hours before installation.
- Mark the center of the room and plan the layout for a balanced look, working outward from the center.
- Place each plank on the subfloor, pressing down firmly to ensure a secure fit.
- Trim planks as needed for edges and corners, ensuring a snug fit.
- In high-traffic areas or for larger installations, adhesive may be applied to the perimeter or under individual planks as recommended by Karndean.
Looselay flooring is particularly suitable for temporary spaces or areas where planks may need to be removed and reinstalled.
