Water-based Interior Wax for wooden walls, ceilings and furniture – 7393 and 7394

A fresh white finish for interior wood

Osmo Interior Wax gives wooden panelling, furniture and doors a white finish with a soft, wax-like character. The water-based formula dries to a satin sheen.

Use it for new projects or to refresh wood previously treated with the same product. It is a practical choice for brightening a timber ceiling or refinishing a wooden cabinet.

Which white finish should you choose?

• 7393 – Transparent White: a light white tint that allows the original wood colour and grain to contribute clearly to the result.

• 7394 – Opaque White: a more solid white appearance, while the texture of the wood can remain recognisable.

Wood species, preparation and application amount all affect the appearance. Always test the finish on the wood you intend to treat.

Suitable interior applications

• Wooden wall and ceiling panelling.

• Tongue-and-groove boards.

• Mouldings and exposed timber beams.

• Furniture and interior doors.

• Wooden children's toys.

According to the manufacturer, the dried finish is suitable for children's toys under EN 71-3 and resistant to saliva and perspiration under DIN 53160.

Protection with a wax-like feel

The finish is water-repellent, resistant to dirt and abrasion, and pleasant to touch. It retains a microporous character.

Interior Wax is a complete finishing system in its own right. Do not dilute it or mix it with other finishes.

Preparing the wood

The surface must be clean, dry and frost-free. Maximum wood moisture content is 18%, and the application temperature must be at least 10°C.

Completely remove old paint and varnish coatings. A suitable existing Interior Wax finish usually only needs thorough cleaning before recoating. Always check adhesion and appearance with a trial application.

How to apply Interior Wax

1. Stir thoroughly before use.

2. Apply a thin, even coat with a suitable flat brush or microfibre roller.

3. Work along the grain and spread the finish carefully.

4. Allow it to dry with good ventilation.

5. Apply a second thin coat to bare wood.

Sanding between coats is not normally required. If raised fibres need smoothing, lightly sand the dried first coat with P240–360 and remove the dust before recoating.

For renovation of a suitable existing finish, one coat is usually sufficient.

Drying time and coverage

• Drying time per coat: approximately 3–4 hours at 20–23°C and 50–65% relative humidity.

• Coverage: approximately 16 m² per litre per coat on smooth, planed or sanded wood.

• Bare wood: two coats.

• Sizes offered on this product page: 0.75 and 2.5 litres.

Lower temperatures and higher humidity extend drying times. Rough or highly absorbent wood may require more product.

Practical advice and safe use

When renovating tongue-and-groove ceiling boards, avoid allowing the finish to bond the joints together. This can cause stress and cracking.

Clean brushes and rollers immediately after use with soap and water. Protect the product from frost and temperatures above 30°C.

Contains preservatives that may cause an allergic reaction. Keep out of reach of children and wear suitable respiratory protection when sanding.
