For almost all interior timber projects, we recommend Whittle Waxes Evolution Hardwax Oil. It is suitable for timber floors, kitchen benchtops, bathroom vanities, dining tables, river tables, furniture, wooden utensils, chopping boards, guitars, spearguns and most other interior wood surfaces.

Evolution Hardwax Oil penetrates into the timber to provide a durable, water-repellent, microporous finish that enhances the natural beauty of the wood while allowing it to breathe. It is easy to apply, simple to maintain and spot repair, and is certified food safe and toy safe once fully cured.

Choose the finish that best suits your project:
Matte – minimal sheen with a natural look.
Classic – low sheen and our most popular finish.
Satin – a soft lustre with added richness.
Gloss – a higher sheen that highlights the timber grain.

Simply prepare the timber correctly and apply the oil according to the product instructions for a beautiful, long-lasting finish.

For the best results, we recommend applying Evolution Hardwax Oil with a 10mm microfibre roller, such as the Uni-Pro range. A quality microfibre roller provides an even coat, helps achieve the correct coverage and leaves a smooth, professional finish. We stock suitable rollers in our online store.

The lifespan depends on the amount of wear and how well the surface is maintained, but on timber floors Evolution Hardwax Oil will typically last 5–7 years or longer before needing to be refreshed. One of the advantages of hardwax oil is that worn areas can usually be maintained or repaired without sanding and refinishing the entire floor.

Generally not. In most cases, you can simply clean the surface thoroughly and apply a fresh coat of Evolution Hardwax Oil. If needed, a light sand is all that's required before recoating. Unlike many film-forming finishes, hardwax oil can usually be refreshed without sanding the timber back to bare wood.

Coverage depends on the timber species, surface preparation and application method. As a guide, Evolution Hardwax Oil covers approximately 20–30 m² per litre. Dense timbers generally provide greater coverage than more porous species.

Timber naturally changes colour over time due to oxidation and exposure to UV light, regardless of the finish used. Evolution Hardwax Oil enhances the timber's natural appearance without the strong ambering often associated with some finishes. Under normal conditions, exposure to natural light helps maintain a clear, natural-looking finish while allowing the timber to age naturally.

Evolution Hardwax Oil can be applied over some existing finishes, but not all. We recommend testing a small, inconspicuous area first to check compatibility. Because the performance of any hardwax oil depends on the existing coating, Whittle Waxes cannot guarantee results when Evolution Hardwax Oil is applied over another finish.

Yes. Evolution Hardwax Oil is an excellent choice for bathroom vanities, timber benchtops and other interior timber in bathrooms. It is both water resistant and water repellent, helping to protect the timber from moisture while allowing it to breathe. As with any timber surface, wipe up standing water promptly and maintain the finish as required.

Yes. Most Whittle Waxes products, including Evolution Hardwax Oil, are designed for DIY application. With the right preparation, a quality brush or microfibre roller, and by following the application instructions, you can achieve a professional, durable finish yourself.

Allow Evolution Hardwax Oil to dry overnight between coats under normal conditions. After the final coat, the surface should be left to cure for 8–10 days before heavy use, allowing the hardwax oil to achieve maximum durability and longevity.

Slow drying is usually caused by applying too much product. Applying Evolution Hardwax Oil too heavily can significantly increase drying times. Ensure any excess Evolution Colours or Stains is wiped off before coating. To speed up drying, increase ventilation by opening doors and windows or using a fan, and keep the room warm.

Sand the timber to 120 grit (or finer if sanding marks remain, as darker colours can highlight scratches). Apply a generous coat of Evolution Colours with a clean cloth, ensuring even coverage, then wipe off any excess. For larger areas, a machine can be used, but be sure to remove excess product and avoid swirl marks. Allow the colour to dry overnight before applying two coats of Evolution Hardwax Oil in your preferred sheen.

Yes. This is completely normal after the first coat. Timber absorbs hardwax oil at different rates depending on the grain and density, so some areas may appear patchy. Once the second coat of Evolution Hardwax Oil is applied, the finish will normally become even and consistent.

Yes. Once fully cured, Evolution Hardwax Oil is safe for children's toys and cots, complying with EN 71-3 (toy safety) and DIN 53160 (saliva and perspiration resistance). It contains no added biocidal substances or preservatives, making it a safe choice for toys, cots and other interior timber items used by children.

Yes. One of the major advantages of Evolution Hardwax Oil is that it can usually be spot repaired without sanding and refinishing the entire floor. The success of the repair depends on the age of the floor, the extent of the damage and correct application, but new coats bond well with existing hardwax oil when the surface is properly prepared.

Cloths, towels or applicators used with Whittle Waxes products should always be laid flat to dry completely before disposal or storage. Oily cloths can generate heat as they dry and may self-combust if left bunched up or in a pile. Always follow the safety instructions on the product label.

A dull appearance is usually caused by using the wrong cleaning products or cleaning methods. Clean the surface with Whittle Waxes Floor Care, a concentrated cleaner that removes dirt while helping to replenish and revive the finish. Regular maintenance with the correct cleaner will help keep your timber looking its best.

Wipe up any spills as soon as possible to minimise the risk of staining or damage. Evolution Hardwax Oil is water repellent, but prolonged exposure to liquids—particularly acidic or alkaline substances such as wine, vinegar, citrus juice or urine—can mark the timber if left on the surface for too long.

Yes. For most timber benchtops and countertops, two coats of Evolution Hardwax Oil provide a durable, water-repellent, grease-resistant finish that is food safe once fully cured, easy to maintain and simple to spot repair if damaged. Unlike epoxy, hardwax oil enhances the natural feel and appearance of the timber while providing excellent everyday protection for kitchens and other interior timber surfaces.

Yes. Vacuum or sweep regularly to remove grit and dirt that can cause scratches. Clean the surface with Whittle Waxes Floor Care and periodically maintain it with Whittle Waxes Wax Polish to help protect the finish and keep your timber looking its best. See our Cleaning & Maintenance section for more information.

Yes. A skin can form on Evolution Hardwax Oil once the tin has been opened. Simply remove the skin, stir the remaining oil thoroughly and use as normal. To minimise skin formation and extend the life of opened tins, we recommend storing them in StopLossBags, available in our online shop. If you're completing a project over several months, purchasing smaller containers can also help reduce air exposure.

Clean brushes and rollers as soon as possible after use with Whittle Waxes Special Thinner. If Special Thinner is not available, white spirit can also be used. Proper cleaning will help extend the life of your application tools and prepare them for future use.

Not always. A newly installed timber floor does not need sanding if it has already been prepared to a smooth finish equivalent to 120 grit sandpaper. Evolution Hardwax Oil is not a grain filler, so the quality of the finished surface depends on the quality of the timber preparation. The smoother and more even the timber, the better the final result.

No finish can completely prevent scratches from dogs' claws. Evolution Hardwax Oil provides a durable finish, but large dogs or dogs with freshly trimmed, sharp claws may still scratch the surface. The likelihood of scratching also depends on the timber species, with softer timbers marking more easily than harder ones. Keeping your dog's claws naturally worn or well maintained will help minimise scratching.

Yes. Evolution Hardwax Oil is suitable for timber floors with underfloor heating. For the best results, switch the heating off 6–8 hours before application to prevent the hardwax oil drying too quickly, which can lead to brush or roller marks. Once fully cured, Evolution Hardwax Oil performs well on heated floors and is resistant to normal underfloor heating temperatures.

Yes. Evolution Hardwax Oil can be used on timber surfaces around fireplaces. Once fully cured, it is resistant to the temperatures normally encountered around a domestic fireplace. However, like all timber finishes, it should not be exposed to direct flames or excessive heat, and all applicable fireplace clearance and building safety requirements should be followed.

Evolution Hardwax Oil is not recommended for exterior use, including timber around outdoor swimming pools. For indoor swimming pools, however, it is suitable and offers good resistance to moisture and common pool chemicals such as chlorine. For improved slip resistance in these areas, consider adding Whittle Waxes Anti-Slip.

Yes. Evolution Hardwax Oil can be used to seal porous natural stone, such as slate. Because it is an oil-based finish, it may deepen or change the colour of the stone, so always test a small, inconspicuous area first. Once absorbed into porous stone, Evolution Hardwax Oil cannot be removed.

Yes. Before you start, plan the order in which you'll coat each room so that you always have a clear path to an exit and avoid walking on freshly finished floors. Evolution Hardwax Oil can be applied in any direction initially, but the final passes should always follow the direction of the timber boards for the best appearance. For larger projects and homes with multiple rooms, we recommend watching our Applying Evolution Hardwax Oil video, where Giles explains the best approach step by step.

To minimise roller overlap marks, avoid applying too much Evolution Hardwax Oil and always roll excess product onto an untreated area before overlapping a previously coated section. Work along the direction of the timber boards, ideally from wall to wall, and finish each section by lightly lifting the roller as it enters the previous wet area to feather the edge. This helps produce a smooth, even finish.

Yes, but don't brush too far ahead of the roller. If the brushed edge starts to dry before you roll into it, the roller can lift the partially cured finish and leave visible marks. As a guide, avoid going back over Evolution Hardwax Oil after about 10 minutes, as it will already have started to set. Brush the edges first, then follow closely with the roller, rolling as close to the skirting as possible for a seamless finish.

Yes. We recommend REDIfill Wood Filler for repairing small holes, chips, dents and other minor damage before applying Evolution Hardwax Oil. Follow the application instructions provided with the filler and allow it to dry fully before sanding smooth. Keep in mind that all wood fillers absorb colour differently from natural timber, so the repaired area may not match the surrounding wood exactly, particularly when using coloured finishes.

We don't recommend using methylated spirits or other solvents to remove shellac before applying Evolution Hardwax Oil. While the solvent will dissolve the shellac, it can also carry it into the timber, where it may interfere with the absorption of the hardwax oil. This can result in an uneven appearance and reduced durability. For the best finish, sand the floor back to bare timber before applying Evolution Hardwax Oil.
