Maintenance and repair of Kährs wood floors 3 MAINTENANCE AND REPAIR OF KÄHRS WOOD FLOORS IN DOMESTIC ENVIRONMENTS To retain their original durability and beautiful appearance, Kährs wood floors should be maintained following a simple regime. We have the strongest floor lacquer on the market, which reduces the risk of microscratches – the tiny, irritating scratches that can appear in the lacquer surface when, for example, furniture with worn protective pads is dragged across the floor.
Maintenance and repair of Kährs wood floors 4 Maintenance and repair of UV-lacquered floors Preventive measures Lacquered floors can be given a supplementary surface treatment with Kährs Lacquer. The main reason for this is to prevent water penetrating the joints between boards through capillary action. Note that re-lacquering produces a more “plastic” surface than a factorylacquered floor, and that scratches are more visible because the lacquer used for re-lacquering is less scratch-resistant.
Maintenance and repair of Kährs wood floors 5 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.

Cleaning For daily cleaning, use dry methods, e.g. vacuuming.

Maintenance and repair of Kährs wood floors 9 Buffing the treated floor makes the surface more dirt-resistant and easy to clean, with higher gloss. Buff manually using a cloth or with a polishing machine (red floor pad) the day after maintenance has been carried out. Maintenance using Watco Satin Oil. Method Two.

Maintenance and repair of Kährs wood floors 10 MAINTENANCE AND REPAIR OF KÄHRS WOOD FLOORS IN PUBLIC ENVIRONMENTS Public environment refers to all environments that are not similar or equivalent to domestic environments in terms of wear. Examples of public environments, similar to a domestic environment, are day-care centres and offices subject to light wear. However, in these cases maintenance must be carried out more frequently than in a domestic environment.
Maintenance and repair of Kährs wood floors 11 Maintenance and repair of UV-lacquered floors in public environments Preventive measures Normally, the factory-lacquered surface needs to be reinforced with additional coats of lacquer (unless the area of application is comparable with a domestic environment). Use any currently available lacquer designed for re-lacquering factory-treated wood floors without the need for sanding down first. Follow the lacquer manufacturer’s instructions.
Maintenance and repair of Kährs wood floors 12 Re-lacquering Kährs UV-lacquered floors: When re-lacquering, the temperature in the room and of the lacquer must not be lower than 15°C. The entire floor area must be relacquered to prevent the formation of ridges of lacquer. The surface to be lacquered must be thoroughly cleaned using Kährs Remover. Use a rotary floor scrubber (150 rpm, red pad) with Kährs Remover diluted in water 1/5 to ensure the surface is free from dirt and grease.

If small areas have been scratched (under chairs, etc.) the floor can be treated with Kährs UV/Nature Oil Refresher. This conceals the microscratches. Partial repairs to Kährs multi-layer parquet and Linnea: If a small area is damaged or worn through, or needs to be repaired for any other reason, it is best to replace the damaged boards.

With correct and regular maintenance, no surface withstands tough demands better. Preventive measures The factory-oiled surface needs to be reinforced with either Kährs UV/Nature Oil Refresher, method 1, or Watco Satin Oil, method 2.
Maintenance and repair of Kährs wood floors 16 subsequent maintenance is at least twice a year. Remember also that areas subjected to greater wear than the rest of the floor can be given localised maintenance. The higher the frequency, the better the results. Clean the floor thoroughly. Buff the floor using a thin coat of Watco Satin Oil with a scrubbing machine and floor cloth (150 rpm). The quantity of oil is approx. 1–3 g/m2 (corresponds to approx. 100– 300 ml of oil per 100 m2).

For best results, re-use a board that was laid near the damaged one, because it will be a similar colour and have comparable wear. Install the new board where its “brand new” colour is less obvious, e.g. near a wall.
Maintenance and repair of Kährs wood floors 21 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.
Maintenance and repair of Kährs wood floors 22 Replacing strips Only 3-strip products can have strips replaced. 1. The defective strips must be removed without damaging the lacquer edges of the surrounding strips. Therefore, cut through the lacquer layer in the joints around the relevant strip. Use a straight edge and a very sharp knife. 2. Then carefully chisel out the strip using a wood chisel. 3.
