Before you begin

1
Humidity

Creating the perfect environment is key to enjoying your Kährs wood floor for years to come. Keep the relative humidity between 30-60%, before, during, and after installation, to minimize expansion or contraction.

2
Dry & Flat subfloor

A solid start makes all the difference when installing your Kährs wood floor. Start with a dry, level, and clean subfloor to create a foundation that lasts. Remove any old carpeting, debris, or dust for a pristine surface that sets the stage for a flawless installation.

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 seasoned DIY pros can benefit from a few smart tips to ensure your Kährs hardwood floor installs seamlessly:

  • Plan ahead: Measure carefully and calculate the number of boards you’ll need for the room’s width. If your last row would be less than 30 mm, adjust the first row for a perfect fit.

  • Mix for a natural look: Open several packs and blend boards to create a beautifully balanced color variation. Be sure to check for defects before you start laying the floor.

  • Lay it right: Position boards lengthways in the room for a more spacious and stylish visual.

  • Room to breathe: Always leave enough space between the floor and the walls to allow for natural expansion and movement.

  • Correct orientation: The groove side of each board should face into the room for the perfect fit.

  • Perfect angle: Install boards at a 20-30° angle to lock them securely in place.

  • Tight joints: Use a Kährs hand block to lock the short joints snugly.

  • End joint offset: Keep a 500 mm stagger in end joints between rows for extra stability.

  • Smart cuts: Start each new row with the leftover piece from the previous row to minimize waste and create a seamless flow.

With these steps, you’ll enjoy a flawless, long-lasting wood floor that’s as beautiful as it is functional.
