A water-based, fast-drying wood sealer. For wood professionals only.
- Quick-drying, sandable after 120 minutes

WOCA’s Natural Sealer is a single-component solution designed to maintain the wood’s natural appearance while preparing it for finishing with WOCA Optima or WOCA Advanced XP 2K. It reduces side bonding by sealing floor joints and prevents black stains caused by tannin migration. This sealer forms a strong, lasting bond with both the wood fibers and the WOCA topcoat. Enjoy smooth, uniform application and exceptional results with WOCA’s advanced formula—allowing for easy sanding without overlap marks or uneven flow, delivering reliable and seamless protection.
Also available in White for a lighter look to the wood.
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.
How To
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. Untreated floors need to be devoid of dirt, grease, wax, and dust. Previously finished floors require sanding down to bare wood before applying the sealer. Vacuum thoroughly and tack the floor. Shake the Natural Sealer thoroughly before use.
Always remember to test on a less visible spot to check the compatibility of the surface with the product.
- Apply Natural Sealer undiluted with roller, lengthwise, and allow the surface to dry.
- Sand the surface with 120-180 grit and vacuum clean the surface thoroughly.
- Apply a 1 coat of WOCA Water Based Finish. Leave the surface to dry until next day.
- The next day, apply another 1-2 coats of WOCA Water Based Finish (refer to specific WOCA Water Based Finish product for recommended number of coats).
