Osmo Door Oil 1L

Specialist Protection for Interior Wooden Doors

Doors are exposed to regular handling, fingerprints, cleaning, movement and changes in indoor humidity. Osmo Door-Oil protects the timber without enclosing it beneath a brittle surface film.

The cured finish remains elastic and microporous, allowing the wood to breathe naturally while reducing the risk of the surface becoming dry, brittle or difficult to maintain.

Before Oiling a Veneered Door

Veneered doors require more care than solid timber because the visible wood layer may be extremely thin.

• Check the door manufacturer’s finishing instructions.
• Confirm that oil finishing is permitted.
• Confirm whether sanding or renovation is allowed.
• Avoid aggressive sanding that may cut through the veneer.
• Do not assume both faces use the same veneer construction.
• Complete a trial application in an inconspicuous area where possible.
• Do not coat over glue, silicone, polish or factory contamination.
• Apply the finish exceptionally thinly and evenly.

Available Sizes

Coverage is based on approximately 24m² per litre for one thin coat. Actual coverage will vary according to timber species, porosity, sanding, surface texture and the amount applied.

Technical Information

Coverage and drying times are approximate. Temperature, humidity, ventilation, timber species, veneer construction and application thickness will affect the result.

Surface Preparation

• Ensure the timber is clean, dry, frost-free and free from grease, polish, wax, silicone and contamination.
• Timber moisture content must not exceed approximately 18%.
• Shake and mix Door-Oil thoroughly before use, especially 3033 Raw.
• Do not thin the product.
• Completely remove old paints, varnishes and lacquers where the door construction permits.
• Clean compatible old microporous oil finishes thoroughly before recoating.
• Confirm that veneered doors can be sanded and refinished.
• For solid timber doors, sand consistently and normally complete the final sanding around P120–P150.
• Avoid sanding too finely when using 3033 Raw, as reduced absorption may leave white pigment sitting visibly on the surface.
• Vacuum thoroughly, including panels, mouldings, edges, joints and corners.
• Fill suitable cracks, joints and holes before the final sanding stage.
• Apply the first coat to all faces and edges before installation where practical.
• Complete a representative test area before treating the complete door.

New Door Application

1. Bring the product to normal room temperature and shake or stir it thoroughly. Do not thin.
2. Ensure the door is clean, dry and completely free from sanding dust.
3. Support the door securely in a clean, well-ventilated area.
4. Where practical, apply the first coat to both faces, edges and concealed areas before installation.
5. Apply the first coat thinly using an Osmo Flat Brush or suitable microfibre roller.
6. Work with the timber grain and spread the product evenly.
7. Check panels, mouldings, corners, edges and joints for heavy deposits or runs.
8. For 3033 Raw, remove or redistribute visible white pigment before drying.
9. Allow the first coat to dry for approximately 12–24 hours with good ventilation.
10. Once completely dry, apply the second coat equally thinly.
11. Continue ventilating throughout drying.
12. Avoid closing the door tightly against seals or frames until the finish is dry.

Applying 3033 Raw Matt

1. Shake and stir the product thoroughly to distribute the white pigment.
2. Apply an exceptionally thin coat with the timber grain.
3. Work methodically and avoid heavy overlaps.
4. Inspect the door from several angles while the coating remains wet.
5. Brush out or remove any visible white pigment, cloudy areas or heavy marks.
6. Pay particular attention to mouldings, open grain and coarse sanding marks where pigment may collect.
7. Allow the first coat to dry fully before applying the second.
8. Apply the second coat just as thinly and consistently.

Applying to Frames, Linings and Architraves

1. Prepare and sand the timber consistently.
2. Remove all dust and contamination.
3. Use a suitably sized brush for mouldings, rebates and detailed sections.
4. Apply Door-Oil very thinly with the grain.
5. Check corners and rebates for runs or heavy build-up.
6. Avoid coating rubber seals, ironmongery and adjacent finished surfaces.
7. Allow the first coat to dry fully before applying the second.
8. Keep doors open or suitably supported until the finish has dried.

Drying and Use

Cleaning and Maintenance

Use a soft cloth and avoid saturating the door with water. Remove fingerprints, dirt and spillages promptly, particularly around handles, lower rails and frequently touched edges.

Renovating a Previously Oiled Door

1. Remove dust and loose dirt.
2. Clean the door using a suitable Osmo cleaning product.
3. Allow the surface to dry completely.
4. Inspect for polish, silicone, grease, deep scratches or failed areas.
5. Confirm that any veneered surface can be safely prepared.
6. Lightly prepare damaged areas where appropriate.
7. Remove all dust.
8. Apply one exceptionally thin coat of the matching Door-Oil finish.
9. Feather local repairs carefully into the surrounding area.
10. Ventilate well and allow the coating to dry before closing or handling heavily.

Important Application Notes

• Use on suitable interior wooden doors and joinery only.
• Apply two exceptionally thin coats to new bare timber.
• Shake and stir thoroughly before use.
• Do not thin the product.
• Apply with an Osmo Flat Brush or suitable microfibre roller.
• Maintain good ventilation during drying.
• Allow approximately 12–24 hours between coats.
• Check door-manufacturer guidance before treating veneered doors.
• Avoid aggressive sanding of thin veneers.
• Clear Satin enriches and darkens the natural timber colour.
• Raw Matt contains white pigment and is intended mainly for pale timber.
• Remove visible white pigment before allowing Raw to dry.
• Heavy application can cause slow drying and uneven sheen.
• Ingredient-rich solid hardwoods may require Clear Extra Thin.
• Apply only one exceptionally thin cloth coat inside cupboards.
• Avoid multipurpose cleaners, washing-up liquid, bleach and abrasives.
• Always complete a trial application on the actual timber.

Tool Cleaning

Clean suitable brushes, rollers and application tools immediately after use with Osmo Brush Cleaner & Thinner .

Do not reuse applicators containing uncured Clear Satin when applying Raw Matt, as contamination may alter the final appearance.
