Surface preparation

The wood surface must be dry, well sanded and free from sanding dust and other dirt.

Application

Untreated and clean-sanded surfaces: Fill the gaps with GAP parquet putty. Prime the surface with Teknos primer lacquer according to the instructions. Intersand, if necessary, with sandpaper or with an abrasive net n:o 150 after the first primer coat. Mix KALLE PRO hardener and KALLE PRO parquet lacquer. Pour the hardener into the lacquer container. Shake the lacquer container vigorously for at least 30 seconds. Let the lacquer deaerate for 5–10 minutes. Apply 2–3 coats of KALLE PRO parquet lacquer with a flotex applicator along the grain of the wood. Do not close the container after the hardener has been added! (The reaction between the hardener and the lacquer produces small amounts of gas (carbon dioxide.) Factory lacquered parquets or lacquered floors (maintenance lacquering): Clean the floor thoroughly. Intersand gently by using sandpaper n:o 100–150. Remove the sanding dust with a vacuum cleaner and finish with a clean damp cloth. Apply the first coat of KALLE PRO lacquer with a stainless steel trowel, and the following 1–2 coats with a felt trowel. Note! If wax has been used for floor care ensure the compatibility with the maintenance lacquer beforehand by consulting the producers. If the floor has previously been treated with oil, urethane or alkyd lacquer, the floor must be sanded to bare wood before lacquering. If the second coat is not applied within 48 hours after the first coat, intersand the floor gently. Ensure that the previous lacquer coat has fully dried before applying a new one. Always stir lacquer thoroughly before use. Note! Some rubber types in carpets and anti-slip materials may contain plasticisers that can cause permanent damage to the surface and colour of the protective coat.

Application conditions

The surface to be varnished has to be dry. The moisture content of the wood should be 7 ±2 % by weight. The temperature of the air, the surface and the lacquer shall be above +18 - 24°C and the relative humidity of the air 40 - 60% during the time of application and drying.

Maintenance

The varnished surface reaches its final hardness and washability within 2 weeks. Rough handling and washing is to be avoided during this period. Stained surfaces can be cleaned with a moist cleaning cloth or mop. Use a neutral detergent. Very dirty surfaces can later be cleaned with a slightly alkaline universal washing detergent.
