Kahrs Fitting Guide

Laying Kahrs engineered wood flooring is easy due to the ingenious Woodloc® and Woodloc® 5S joints. The boards lock together mechanically. The perfect fit enhances the durability of the floor.

Before installation keeps the boards in their packaging. Read the instructions carefully before fitting. The subfloor must be dry, level and solid. Remove carpets before starting.

Kahrs flooring is installed as a floating floor. The planks are installed loosely on the subfloor and linked together with Kahrs Woodloc joint system. Leave an allowance for 5% waste when installing. Use a flooring underlay when installing Kahrs flooring, and a Damp Proof Membrane for concrete subfloors.

Installation instructions for Kahrs wooden floors with woodloc® joints for installation on the level and fixed surfaces.

Complete installation instructions are provided in every other bundle. Use Kahrs' installation tools.


Start with calculating how many floorboards are required. If the last row is narrower than 30 mm, saw the first row of boards as well. When installing Kahrs flooring with Woodloc® joints, it is easier for you to start the installation on the long side that has the most doors. If there are doors along the short side of the room begin each row of boards at these. The boards can be installed both from left and right.

  1. Begin in one corner installing from left to right with the bottom lip out towards the room. The long side distance to the wall can be adjusted later when three rows have been installed. It's often simpler to start the row of boards at the door.
  2. Press the next floorboard at an angle to the first and lay it down.
  3. Continue to work the same way with the rest of the first row.
  4. Cut the final board in the first row to the required length and start the next row with the leftover piece. The boards' end joints are staggered by at least 500 mm.
  5. Put the floorboard at an angle to the previous board in front. Knock lightly with a block while gently pressing the board down.
  6. Push in a Kährs installation key under the board you have already laid down at the short end.
  7. Continue by pressing in the next board's short end at an angle and lay down the long side.
  8. Take away the installation key and knock lightly with the hand block on the long side. At the same time gently press the board down and it will move into place.
  9. The floor's distance to the walls can be adjusted after laying three rows. Place the keys between the floor and wall and remove them once the installation of the floor is finished.
  10. The first-floor row needs adjustment sometimes to an uneven wall. Mark the wall's contour on the floorboards. Then loosen the boards in the first row, grip them by the long side, pull upwards, meanwhile, knock gently against the joint. Saw where needed.
  11. Replace the sawn floorboards from left to right. First angle in the short side and then the long side. Place keys between the wall and floor.
  12. Drill holes in the board for heater pipes at least 20 mm wider than the pipe's diameter. Saw. When the floor has been laid down, glue the sawn-out piece and cover the holes with pipe collars.
  13. If the door liner needs cutting use a floorboard as an underlay to get the exact measurement. If you need to saw lengthwise protect the board's joint.
  14. Lay the last board on top of the previous board with an approximately 5 mm allowance from the wall. Spot the saw cut with the help of a piece of the board without locking moulding. Install the sawn board.
  15. Repeat the procedure with the next one. Fit the skirting boards without pressing them down so that the floor is locked. Use level mouldings when making the transition to another room.
  16. The boards can be installed from all directions when necessary. This helps installation around doors, for instance. If you cannot gain access to angle the board under a door liner or low-fitting radiator, start by cutting away about 2/3 of the locking moulding. Then glue and push the board into position. Woodloc® cannot be installed with end joints against a long side.
