FAQs

Is this product suitable for interior wood?

No, the Osmo One Coat HS Plus is specifically formulated for outdoor wood applications and is not recommended for interior use.

How much area does one liter cover?

The coverage for one coat is approximately 26 m²/1 litre, but this can vary depending on the type and absorbency of the wood.

Can I apply this over a previously painted surface?

This product is best applied to bare wood or over existing microporous finishes. If the previous coating is a non-microporous paint, it may need to be removed or sanded thoroughly for proper adhesion.

How long does the finish typically last outdoors?

The longevity of the finish depends on environmental exposure. It is designed to offer durable protection, but reapplication may be needed every few years for optimal appearance and protection.

What tools should I use for application?

It is recommended to apply the product thinly and evenly using an Osmo Flat Brush or a Microfibre Roller.

Can I use this on hardwood decking?

While suitable for many outdoor woods, it's always best to test on an inconspicuous area of hardwood decking first to ensure compatibility and desired results, as hardwoods can vary in their porosity and oil content.

How should I store the product if I have leftovers?

Store in a cool, dry place, away from direct sunlight and frost, with the lid tightly sealed. Ensure the lid is clean before sealing to prevent air ingress.

Troubleshooting

Uneven color or finish after application.

This can occur from over-application or inconsistent spreading. Ensure the product is applied thinly and evenly, following the grain. If the issue persists, light sanding and reapplication may be necessary.

Wood is not drying properly.

Check environmental conditions; low temperatures, high humidity, or poor ventilation can significantly slow drying. Ensure the product was applied thinly and that the wood was completely dry before application. Move the item to a warmer, drier, well-ventilated area if possible.

Product appears too thick or sticky during application.

Ensure the product has been thoroughly stirred. If it is unusually thick due to cold storage, allow it to reach room temperature before application. Apply thinly; do not try to force a thick coat.

Existing finish is peeling or flaking.

The product is designed to work best on clean, bare wood or over sound, microporous finishes. If the existing finish is not sound, it must be removed (sanded) back to bare wood before applying the Osmo One Coat HS Plus.

Setup, Compatibility & Care

Setup: Ensure the wood surface is clean, dry, and free from dust or debris before application. For old finishes, ensure they are sound or properly prepared. Stir the product thoroughly before use.

Application: Apply thinly and evenly along the grain of the wood using an Osmo Flat Brush or a Microfibre Roller. Avoid over-application, as this can lead to issues with drying and finish.

Drying Time: Allow approximately 12 hours of drying time in good ventilation. Actual drying time will vary based on temperature, humidity, and air circulation.

Compatibility: Recommended for outdoor wood applications such as carports, timber cladding, balconies, fences, pergolas, garden furniture, and garden sheds. It is also suitable for renewing old microporous finishes. Test on an inconspicuous area if unsure about compatibility with specific wood types or existing finishes.

Care: Clean tools immediately after use with a solvent suitable for oil-based products. For maintaining the finish on the wood, periodically clean surfaces with a mild detergent and water. Reapplication may be necessary after several years, depending on exposure.
