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 prevent the wood from expanding or contracting. Let your floor settle in naturally by keeping the room temperature steady at 15-23°C and storing your wood packs in this same cozy environment for at least 24 hours before installation. It’s a simple step that makes a big difference, ensuring your floor performs beautifully from day one.
2
Dry 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 your subfloor type, a moisture barrier might be essential to protect your new floor from humidity and ensure its beauty endures. Always check the moisture levels and follow our step-by-step installation guide to guarantee your floor stays as stunning as the day it was installed.

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.
