Korlok: Karndean Explained

Welcome to the world of Karndean, a renowned brand in the flooring industry. In this comprehensive glossary entry, we will delve into one of their most popular product lines, Korlok. Korlok is a type of luxury vinyl flooring that has gained immense popularity for its innovative design, durability, and aesthetic appeal.

Understanding Korlok is essential for anyone considering a new flooring solution, whether you’re a homeowner, interior designer, or a flooring retailer. This glossary entry aims to provide an in-depth understanding of Korlok, from its manufacturing process to its installation, maintenance, and much more.

What is Korlok?

Korlok is a range of luxury vinyl flooring produced by Karndean. It is known for its realistic wood and stone effects, which are achieved through advanced printing and texturing techniques. Korlok flooring is designed to be easy to install, durable, and low maintenance, making it a popular choice for both residential and commercial settings.

The name ‘Korlok’ is derived from the unique locking system used in these flooring planks. This system, known as the 5G vertical click locking mechanism, allows for quick and easy installation. The Korlok range is also known for its acoustic qualities, thanks to the pre-attached acoustic foam backing.

Composition of Korlok

Korlok flooring is composed of multiple layers, each serving a specific purpose. The top layer, known as the wear layer, is made of a clear, durable material that protects the design layer beneath it. This layer is resistant to scratches, scuffs, and stains, ensuring the longevity of the flooring.

The design layer, which sits beneath the wear layer, is where the realistic wood or stone effect is printed. This layer is followed by the stability layer, which provides dimensional stability to the plank. The final layer is the pre-attached acoustic foam backing, which enhances the sound insulation properties of the flooring.

Styles and Designs

Korlok offers a wide range of styles and designs to choose from. Whether you prefer the warm tones of traditional oak, the cool hues of limestone, or the rustic charm of reclaimed wood, there’s a Korlok design to suit your taste. Each design is meticulously created to mimic the natural material as closely as possible, resulting in a realistic and visually appealing finish.

Each Korlok plank is also textured to match its design. For instance, a design that mimics the look of hand-scraped wood will also have a texture that replicates the feel of hand-scraped wood. This attention to detail sets Korlok apart from many other types of luxury vinyl flooring.

Manufacturing Process

The manufacturing process of Korlok flooring involves several steps, each crucial in ensuring the final product’s quality and performance. The process begins with the creation of the design layer, where high-definition images of natural materials are printed onto the vinyl. This is followed by the application of the wear layer, which is carefully calibrated to provide the right level of protection without compromising the design.

Next, the stability layer is applied, which gives the flooring its rigidity and dimensional stability. The final step in the manufacturing process is the application of the pre-attached acoustic foam backing. This backing not only enhances the acoustic properties of the flooring but also provides added comfort underfoot.

Quality Control

Quality control is a vital part of the manufacturing process at Karndean. Each batch of Korlok flooring undergoes rigorous testing to ensure it meets the company’s high standards. These tests include checks for dimensional accuracy, visual defects, wear resistance, and more. This meticulous attention to quality ensures that every Korlok floor delivers on its promise of durability and aesthetic appeal.

Furthermore, Karndean is committed to sustainable manufacturing practices. The company strives to minimise waste during the manufacturing process and uses recycled materials wherever possible. This commitment to sustainability is yet another reason why Korlok is a popular choice among environmentally conscious consumers.

Installation of Korlok

One of the key selling points of Korlok flooring is its ease of installation. Thanks to the 5G vertical click locking mechanism, Korlok planks can be installed quickly and easily, with minimal preparation required. This makes Korlok a popular choice for DIY enthusiasts, as well as professional installers.

However, like any flooring solution, proper installation is crucial to ensure the longevity and performance of Korlok flooring. This includes ensuring the subfloor is clean, dry, and level before installation, and following the manufacturer’s instructions for acclimatisation, layout, and fitting.

Tools and Materials

Installing Korlok flooring requires a few basic tools and materials. These include a tape measure, pencil, straight edge, utility knife, and a tapping block. It’s also recommended to have spacers on hand to maintain the correct expansion gap around the perimeter of the room.

In terms of materials, aside from the Korlok flooring planks themselves, you’ll also need a suitable underlay if one is not already attached to the planks. Some installers may also choose to use a flooring adhesive for added stability, although this is not typically necessary thanks to the locking mechanism of Korlok flooring.

Installation Process

The installation process for Korlok flooring begins with acclimatisation. This involves leaving the flooring planks in the room where they will be installed for at least 48 hours prior to installation. This allows the flooring to adjust to the room’s temperature and humidity levels, reducing the risk of expansion or contraction after installation.

Once the flooring has been acclimatised, the installation can begin. This involves laying the planks one by one, starting from one corner of the room and working towards the opposite side. The 5G vertical click locking mechanism allows the planks to be easily clicked into place, with no need for glue or nails.

Maintenance of Korlok

Korlok flooring is designed to be low maintenance, making it an ideal choice for busy households and high-traffic commercial settings. Regular cleaning involves simply sweeping or vacuuming to remove dust and dirt, followed by mopping with a damp (not wet) mop and a pH-neutral cleaner.

While Korlok flooring is resistant to stains and spills, it’s still important to clean up any spills as soon as possible to prevent them from seeping into the joints between the planks. For stubborn stains, a soft-bristle brush can be used to gently scrub the affected area.

Preventive Measures

While Korlok flooring is highly durable, there are still some preventive measures that can be taken to prolong its lifespan. These include using felt pads under furniture legs to prevent scratching, avoiding dragging heavy items across the floor, and using doormats at entrances to reduce the amount of dirt and grit brought onto the floor.

It’s also recommended to avoid exposing Korlok flooring to prolonged periods of direct sunlight, as this can cause the colour to fade over time. Using blinds or curtains to limit sun exposure, especially during the hottest parts of the day, can help to prevent this.

Repair and Replacement

One of the advantages of Korlok flooring is that it’s relatively easy to repair or replace individual planks if they become damaged. This involves carefully removing the damaged plank, cleaning the area underneath, and then clicking a new plank into place.

While this process can be done by a DIY enthusiast, it’s recommended to seek professional help for more extensive repairs or replacements. This ensures the job is done correctly and maintains the integrity of the floor.


In conclusion, Korlok by Karndean is a versatile, durable, and aesthetically pleasing flooring solution that’s suitable for a wide range of settings. Its ease of installation, low maintenance requirements, and wide range of styles and designs make it a popular choice among homeowners and professionals alike.

Whether you’re considering Korlok for your home, your business, or your next design project, we hope this comprehensive glossary entry has provided you with a deeper understanding of this innovative flooring solution. Remember, the key to a successful flooring project lies not only in choosing the right product but also in proper installation and maintenance.
