Natural Sealer is a water-based, quick-drying and sandable wood sealer. The Natural Sealer seals the wood and minimizes tannic acid penetration and side-bonding. It can be used for all untreated or sanded surfaces. Natural Sealer works as a powerful base layer before treatment with other water-based WOCA floor finish.
It is important that both wood and product have a temperature of min. 59°F (preferably around 68°F) and air humidity of approximately 40-60 %. Make sure that the room is well-ventilated for optimal evaporation and drying time. Untreated floors must be free of dirt, grease, wax and dust. Floors that have been finished previously must be sanded down to bare wood before the sealer is applied. Vacuum thoroughly and tack the floor afterwards if necessary, using a tightly-wrung water-soaked cloth. Shake the Natural Sealer thoroughly before use.
Untreated or sanded surfaces: Final sanding must be done with fine sandpaper (grit 120). Vacuum carefully and wipe surface with a cloth hard wrung in clean water. Apply Natural Sealer undiluted with brush or roller and allow the surface to dry. Apply a layer of topcoat with one of the WOCA floor water based finish and sand between coats using grit 150–200 sandpaper. Vacuum carefully and apply another 1-2 topcoats.
Refinishing already finished surfaces: Natural Sealer is only suitable for sealing untreated or sanded wood surfaces.
