REPAIR OF KÄHRS WOOD FLOORS 
REPLACEMENT OF BOARD, GLUED T&G
Replacing tongue and grooved boards
Where there is major damage involving several wear surface
strips, one or several boards may need to be replaced as
follows: Saw through the damaged board all round, approx. 30
mm from its edge. Lift out the sawn piece and clear the
remaining tongue and groove pieces from the surrounding
material. It is simple to check with a piece of board that no
adhesive residue. Check that the new board is the correct
length. Cut off the lower section of the groove on both the
long and short sides. After testing the fit and making any
necessary adjustments, apply glue to the board and place it in
position (see illustration). Place the old board on top of the new
one – on the tongue side – and apply pressure while the
adhesive dries. Multiple boards can be replaced using the same
method.
