Before you begin
1
Humidity

Maintaining the right indoor climate is essential for the longevity and performance of your Kährs wood floor. Keep the relative humidity between 30-60% before, during, and after installation to prevent expansion or contraction of the wood.

Ensure both the room and flooring materials are acclimatized by keeping the temperature between 15-23°C. Wood packs should be stored in this stable environment for at least 24 hours prior to installation for optimal results.

2
Dry subfloor

A properly prepared subfloor is key to a successful wood floor installation. Ensure the surface is dry, level, clean, and structurally sound before laying your Kährs floor. Remove any existing carpeting and debris to create a stable foundation.

Depending on the subfloor type, a moisture barrier may be required to protect against excess humidity and ensure long-term performance. Always check moisture levels and follow our installation guidelines for the best results.

Quick tips

Even experienced installers can benefit from a few key tips to ensure a seamless Kährs hardwood floor installation:

  • Plan ahead: Calculate the number of boards needed for the room’s width. If the final row is less than 30 mm, adjust the first row accordingly.

  • Mix boards for a natural look: Open multiple packs and mix boards to achieve a balanced color variation. Inspect for any defects before installation.

  • Positioning matters: Lay boards lengthways in the room for the best visual effect.

  • Allow for expansion: Ensure there’s adequate space between the floor and walls for natural movement.

  • Correct orientation: The grooved side of each board should face toward the room.

  • Angle for a secure fit: Install boards at a 20-30° angle for proper locking.

  • Lock the short joints: Use a Kährs hand block to ensure a tight fit.

  • Stagger end joints: Maintain a 500 mm displacement of end joints between rows for stability.

  • Trim smartly: Use the cut-off piece from the final board to start the next row, minimizing waste.

By following these steps, you’ll achieve a flawless, long-lasting wood floor with Kährs.
