Product description
Pre-treatment
The surface should be washed with Gjøco House Wash (Hustvätt) to remove grease, debris, and floor wax. Previously painted surfaces and factory-lacquered parquet should be sanded matte with 150-180 grit sandpaper. Using a sanding machine ensures even and thorough sanding. Vacuum and wipe the surface with a lint-free, damp cloth. On previously lacquered/oiled surfaces, an adhesion test should be performed before application.
Method of application
Stir the lacquer thoroughly before and during use. Apply the lacquer quickly and evenly along the length of the boards. On new wood, apply at least 3 coats. On previously lacquered surfaces, at least 2 coats are recommended. Raised wood grain should be sanded down with fine sandpaper. Sanding dust must be thoroughly removed. A light sanding between coats is recommended to ensure adhesion.
Other information
The product must be stored frost-free in accordance with national regulations. Containers must be kept tightly closed and stored in a dry place at an even temperature. Avoid exposing the lacquered surfaces to heavy stress (spills, pressure, etc.) during the first week after painting. Wait at least 3-4 days before placing heavy furniture etc. on the painted surface and 1 week before placing rugs. Spilled water should be wiped up immediately. Water-borne lacquers produce an off-white tint and are therefore best suited for light wood species. A test application is recommended.

Pre-treatment
The floor must be clean, dry, and freshly sanded. Sand the floor with a sanding machine in at least three stages with increasingly fine sandpaper (coarse sanding, medium sanding, and fine sanding with 100-120 grit). Vacuum thoroughly between each sanding. After the final sanding, the floor must be vacuumed very thoroughly and wiped with a damp cloth. Let the floor dry completely before treatment. The wood moisture content should be max 10-12%. The room must be well-ventilated and have the right temperature (+15-25°C).
Application
Stir the lacquer thoroughly before use. Apply Gjøco Clear Lacquer 90 Water-borne with a brush or roller in thin, even coats along the grain. Work systematically across the surface and avoid stopping. Apply 2-3 thin coats at 3-4 hour intervals (water-borne lacquers dry faster than oil-borne ones). Sand lightly between coats with fine sandpaper (150-180 grit) for the best results. Ventilate well during application and drying. The floor can be walked on carefully after 12-24 hours, but full curing takes 7 days. Avoid heavy loads and wet cleaning during the curing period. Maintain the floor regularly according to the manufacturer's recommendations.
