Before you begin

1
Humidity

Maintaining the proper 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 to minimize expansion or contraction the wood.

2
Dry & Flat Subfloor

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

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

Quick tips

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

  • Plan ahead: Calculate the number of boards needed for the room's width. If the final row is less than 2 inches, adjust the first row accordingly.

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

  • Positioning matters: Install the floor along the longest wall or hallway or in the direction of light for most pleasing visual appeal.

  • Allow for expansion: Make sure there’s enough space between the floor and walls for natural movement.

  • Correct orientation: The grooved side of each board should face 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 16-20" offset between the end joints in adjacent rows for stability

  • Trim smartly: Use the cut-off piece from the last board to start the next row and minimize waste.

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