Finishing a window frame indoors

Treat a wooden frame indoors with Osmo Houtbeschermer as a base coat and finish it with Osmo Decorwas Transparant. An oil soaks into the wood and lets it breathe, so the finish will not flake. You can touch up damage locally, without sanding or painting the whole frame.

Window frame or door frame

For the inside of a window frame, first use Houtbeschermer as a base coat and then Decorwas Transparant. The surface becomes water-repellent, which is useful with condensation on the sill. For a door frame next to an interior door, use the same system.

Sunlight and colour

Wood slowly changes colour under the influence of daylight. A clear oil lets this happen evenly, while a coloured product helps to limit discolouration. The pigment absorbs part of the light. If you want to keep light wood species light, choose Decorwas Transparant in a light shade, such as 3111 Wit. Always test on an inconspicuous spot first.

Preparation and application

Lightly sand the frame and make it dust-free. Mask off the glass and wall with tape. Apply the oil thinly with a small brush, in the direction of the grain, and buff off the excess after a few minutes. This gives an even result without drips in the corners. Only remove the tape once the oil is dry.

Maintenance

Remove dust and fingerprints with the Spray-Cleaner. Refresh dull spots with Vloeibare Onderhoudswas. Wipe away condensation on the sill regularly, so the finish there stays looking good for longest.
