Karndean Flooring Problems – What You Need to Know!

1. Installing Over Unlevel Floors

Poor leveling and subfloor preparation are common problems. This affects all kinds of flooring, including Karndean. Poor preparation can lead to many problems. Including buckling, mildew growth, and gaps between planks.

In particular, Karndean flooring offers a wide array of options. But only a few can be considered loose-lay or click-locking floating flooring options.

Many options are available under the Glue-Down format. Which requires tiles/planks to be glued down to the subfloor. It can be a problem for inexperienced DIYers.

Solution: Level and prepare your subfloor for vinyl floor installation. I recommend calling the Karndean flooring company’s professors to do the installation. Instead of doing it yourself this way, you will not void the warranty.

Minor scuffs and scratches are less visible on Karndean flooring.

Still, the protective film of Karndean cannot withstand blemishes and superficial scratches. It can develop scratches when you drag or drop sharp objects or heavy objects like furniture.

Moreover, it would help if you were careful about your pets and kids. Because they can scratch and damage your expensive Karndean flooring.

Or, you may opt for high-quality Karndean flooring with coated and weathered floorboards. But remember, it comes at a higher price.

Solution: It would be wise to be very careful when dragging heavy objects or living objects with sharp edges or ends across the floor. It can cause severe damage, resulting in a costly replacement.

Don’t be surprised if you spot Karndean vinyl floors fading. Especially near the window or areas that receive direct sunlight.

Besides coming already pre-waxed, and PU coated. It cannot withstand excessive and direct sunlight. Since the sun’s UV rays are powerful enough to cause oxidation, the flooring discolors.

Solution: We recommend installing curtains or drapes on the windows. By doing so you might filter the light to reduce the intensity of UV rays on the floor.

4. Peeling At the Edges

Peeling Karndean Flooring problems

One of the common problems of Karndean flooring that most users face is this.

If the Karndean is poorly installed along its edges, it may start peeling off with time. This problem is common and evident on glue-down Karndean vinyl flooring. Especially when the adhesive is worn out.

So, it can lead to further structural damage accelerated by dust and dirt that builds up underneath the peeling. Moreover, it also encourages bacterial growth and peeling.

Solution: Always address the peeling immediately. By removing the curling or peeling, and reapplying the glue. And then gluing down the peeled edges.

5. Bouncing or Separation of Floorboards

Poor subfloor installation can cause the Karndean flooring to start bouncing or separate. Because of that, the floor will start to buckle. And produce a cracking sound as you walk across the floor instead of staying put.

Yet, high humidity can also cause separation or bouncing of the Karndean flooring. If you live in high-humidity areas. Installing a dehumidifier to regulate the humidity to acceptable levels would be helpful.

Solution: You can avoid this issue by ensuring the flooring is installed on an even subfloor. As a result, it will create a uniform contact point all around the floor. If you spot any issue about the subfloor contact professionals immediately.

6. Water-Resistant But Not Waterproof

Water Damage Karndean Flooring problems

Karndean vinyl tiles are often installed in areas with little foot traffic. And minimal wear and tear, which rarely causes problems. But one problem many people face is moisture.

The vinyl tiles can be installed in kitchens without any problems. But they can’t be exposed to water for an extended period because they deteriorate.

Mold can start to develop on Karndean tiles if moisture is left standing for hours. Despite its water resistance, Karndean vinyl flooring is not completely waterproof.

Solution: You can only avoid this issue by installing a moisture barrier under vinyl flooring or turning on a dehumidifier. Also, you must always keep the floor free from standing water.
