Karndean Flooring Installation Guide

Karndean flooring is a fantastic choice for homeowners and businesses looking for durable, stylish, and low-maintenance floors. But how do you install Karndean flooring? Whether you're a DIY enthusiast or considering professional help, this guide will walk you through everything you need to know about installing Karndean flooring for three installation types: Glue Down, Click Lock, and Looselay. Let’s get started!

Does Karndean Flooring Need Underlay?

One of the most common questions is whether Karndean flooring requires underlay. The answer depends on the type of Karndean flooring you’re installing:

Glue Down: Underlay is not required for Glue Down installation. A smooth, clean, and level subfloor is all you need.
Click Lock: While not mandatory, underlay can provide extra cushioning, reduce noise, and improve insulation.
Looselay: Underlay is generally not needed, but some installations might benefit from a thin layer to enhance stability or reduce sound in large spaces.

Pro Tip: Always check Karndean's specific product instructions to confirm the best approach for your installation.

1. How to Install Karndean Glue Down Flooring

Glue Down is the most traditional installation method and offers a strong, permanent solution. Here's how to get it right:

What You’ll Need

Karndean Glue Down planks or tiles
Vinyl flooring adhesive (recommended by Karndean)
Trowel for adhesive application
Utility knife
Measuring tape and straightedge
Roller (50-100 lbs.)
Clean cloth and cleaning solution

Step-by-Step Guide

Prepare the Subfloor:
- Ensure the subfloor is clean, dry, smooth, and level. Remove dust, debris, and grease.
- If the subfloor has cracks or uneven areas, repair them with a leveling compound.
Plan Your Layout:
- Start by marking the center of the room and plan your layout to minimize cuts. Work outward from the center for a balanced look.
Apply the Adhesive:
- Use a trowel to evenly spread the adhesive in sections. Work in manageable areas to prevent the glue from drying before you lay the flooring.
Lay the Tiles or Planks:
- Place each plank or tile firmly into the adhesive. Press down to ensure a good bond, aligning the pieces snugly without gaps.
Roll the Floor:
- Once installed, use a roller to press the flooring into the adhesive and remove air pockets.
Clean Up:
- Wipe away excess adhesive with a clean, damp cloth before it dries. Allow the adhesive to cure for 24 hours before walking on the floor.

Pro Tip: If you are not comfortable in installing the glue down version, try hiring a professional installer!

2. How to Install Karndean Click Lock Flooring

Click Lock flooring is perfect for DIY enthusiasts. It features a simple click-and-lock system that doesn’t require adhesive, making it faster and easier to install.

What You’ll Need

Karndean Click Lock planks
Rubber mallet
Spacers for expansion gaps
Measuring tape and utility knife
Underlay (optional for cushioning or sound reduction)

Step-by-Step Guide

Prepare the Subfloor:
- As with Glue Down, ensure the subfloor is clean, dry, and level. If using underlay, lay it down first.
Acclimate the Flooring:
- Allow the planks to acclimate to the room temperature for 24-48 hours before installation.
Start in a Corner:
- Begin in one corner of the room, leaving a 1/4-inch expansion gap between the flooring and the wall using spacers.
Click and Lock the Planks:
- 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 Across the Room:
- Work row by row, staggering the planks for a natural look. Measure and cut planks as needed for the edges.
Finish and Remove Spacers:
- Once the floor is complete, remove the spacers and add baseboards or trim to cover the expansion gap.

Pro Tip: For Click Lock installations, it’s essential to leave an expansion gap to allow the floor to expand and contract with temperature changes.

3. How to Install Karndean Looselay Flooring

Looselay flooring offers one of the easiest installation methods. The planks use a special backing to grip the subfloor, requiring no adhesive in most cases.

What You’ll Need

Karndean Looselay planks
Utility knife
Measuring tape
Ruler or straightedge
Roller (optional for larger spaces)

Step-by-Step Guide

Prepare the Subfloor:
- As always, ensure the subfloor is clean, smooth, and dry. Any dirt or bumps can prevent the Looselay planks from gripping effectively.
Acclimate the Planks:
- Let the flooring adjust to room temperature for at least 24 hours before installation.
Mark Your Layout:
- Mark the center of the room and plan your layout for a balanced look. Work outward from the center.
Lay the Planks:
- Simply place each plank on the subfloor, pressing down firmly to ensure a secure fit. No adhesive is required unless you're installing in a high-traffic area or large space.
Trim Edges as Needed:
- Use a utility knife to cut planks for edges and corners, ensuring a snug fit.
Secure with Adhesive (Optional):
- For areas with heavy traffic or larger installations, apply adhesive to the perimeter or under individual planks as recommended by Karndean.

Pro Tip: Looselay flooring is ideal for temporary spaces or areas where you may need to replace planks in the future, as they can be easily removed and reinstalled.
