REPAIR OF KÄHRS WOOD FLOORS 
REPAIRS
Partial repairs to multi-layer parquet and Kährs
Linnea:
• Treat small surface scratches and scrape-marks with Kährs
Lacquer Refresher. On deeper scratches, use Kährs Touch-up
Lacquer first.
• Fill small indentations that have cracked the surface with
Kährs Touch-up Lacquer. Dirt can collect in the “hollows” on
brushed products. Remove dirt from individual areas using a
small brush and Kährs Spray Cleaner. Apart from that, look
after floors with brushed boards just like other lacquered
products. Re-lacquer these floors with Kährs Lacquer. The
brushed parts naturally hold more lacquer, and will retain their
brushed appearance even after re-lacquering, if somewhat
less so. Kährs Lacquer Refresher can be used for
maintenance, but the gloss level will gradually increase.
• Fill deep dents, scratches and cracks with Woodfiller or Kährs
Hot-Melt Wax in a matching colour, then lacquer with Kährs
Touch-up Lacquer. Strips or boards with major damage can be
replaced.
RENOVATION
Renovating surface treatment on wood floors:
Microscratches: If small areas of the lacquer have been
scratched (by chairs, tables etc.) the floor can be treated with
Kährs Lacquer Refresher. This conceals the microscratches.
Damp cleaning gradually removes the Lacquer Refresher.
Partial repairs to Kährs multi-layer parquet and Linnea:
If a small area is damaged, worn through or needs to be
repaired for any other reason, it is best to replace the damaged
boards. This is easy with the Woodloc
®
joint. This applies
particularly to stained or special finish boards.
It is important to maintain stained products in good time. Do
not allow the stained finish to wear.
Renovation with Kährs Lacquer (re-lacquering):
The main reason for re-lacquering is that after many years’ use,
the floor needs to be ”freshened up”. The surface to be
lacquered must be cleaned thoroughly with Kährs Spray
Cleaner. If the floor surface is heavily contaminated, use a
rotary floor scrubber (red pad) and Kährs Remover to ensure
that the floor is free from grease and dirt. Remove all Kährs
Lacquer Refresher using Kährs Remover. Then rub down any
residues of Refresher using fine (150 grit) sandpaper or a
sanding disc (150 grit) before re-lacquering. During re-
lacquering, the temperature in the room and of the lacquer
must not be lower than 14°C. The entire floor area must be re-
lacquered to prevent the formation of ridges of lacquer. Apply
the lacquer using a roller or lacquer brush. When re-lacquering,
one coat is enough to cover joints and protect from water.
Remember that the surface to be re-lacquered must not have
been treated previously with wax, polish, etc. This prevents
adhesion, which would mean that the floor would have to be
sanded down to bare wood.
Before re-lacquering, apply lacquer onto a sample area to test
adhesion. If the floor has been re-lacquered previously, follow
the lacquer manufacturer’s instructions. If the floor is likely to
be subjected to heavy wear, apply several coats of lacquer.
The floor can be walked on carefully approx. 8 hours after
lacquering. Rugs can be laid on the floor one week after
lacquering. Be careful with spilt water on the newly lacquered
surface during the first week, because this can cause
permanent stains. Always follow the instruction for the specific
product.
Note that re-lacquering produces a more “plastic” surface
appearance than a factory-lacquered floor, and that scratches
are more visible because the lacquer used for re-lacquering is
less scratch-resistant. Re-lacquering is not carried out in a dust-
free environment, so there is a risk that dust particles will
adhere to the surface and form little bumps that are visible
when the lacquer dries.
Total renovation of a wood floor:
If the floor is heavily worn, or needs renovation for some other
reason, it can be machine-sanded to bare wood and have a
new surface treatment applied.
Note. Kährs Linnea cannot be sanded.
Particular attention must be given to stained products or
products with special finishes. Follow the lacquer
manufacturer’s instructions.
! Underfloor heating must be switched off during re-lacquering.
! When a factory-finished floor that has been glued down using
an MS polymer is re-lacquered, the bond between the new coat
of lacquer and the factory-finished lacquer cannot be
guaranteed.
Note. Any sanding of wood floors includes a risk of
delamination of the wood veneers.
This should always be communicated, in writing, to the
consumer, prior to starting of the renovation job.
