Surface preparation
The wooden surface must be dry, carefully sanded and cleaned from dust and other impurities.
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 an abrasive net n:o 150 after the first primer coat. Mix OPAL hardener and OPAL parquet lacquer together. 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. Finish with 2–3 coats of OPAL parquet lacquer using a lacquer roller or a paint brush 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 one coat of OPAL parquet lacquer with a stainless steel trowel, and 1–2 coats with a lacquer roller or a brush. 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.
Some rubber types in carpets and anti-slip materials may contain plasticisers that can cause permanent surface and colour damage to the lacquer and oil coat.
Application conditions
The surface to be treated must be dry. The moisture content of the wood should be 7 ±2 % by weight. The temperature of the air, the surface and the product 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.
Storage
Storage time: in unopened containers, above +1°C, for 1 year. Must not freeze.
