Compare three professional ways to colour wooden flooring: pigmented hardwax oil, fast-drying wood stain and two-component penetrating oil.
```Osmo Polyx-Oil Tints can create some of the most attractive coloured finishes available for wooden flooring, combining transparent pigment with the natural oils and waxes found within the Polyx-Oil system.
They are straightforward products when used correctly, but coloured hardwax oil is far less forgiving of poor preparation than a standard clear finish.
The final colour does not come from the tin alone. Timber species, natural colour, density, age, porosity, sanding preparation and application technique can all change how the pigment is absorbed.
This means the same Tint can look noticeably different on two floors ā and even individual boards within the same floor can naturally accept the colour differently.
This guide explains how to use Osmo Polyx-Oil Tints, including preparation, sanding, test areas, contamination, white-pad and floor-brush application, plank versus herringbone, drying, topcoats, 3040 White and optional professional techniques for increasing pigment uptake.
Which Osmo Polyx-Oil Tint Colours Are Available?
The standard WWFS Polyx-Oil Tints range includes:
- 3040 White
- 3067 Light Grey
- 3071 Honey
- 3072 Amber
- 3073 Terra
- 3074 Graphite
- 3075 Black
These are transparent colours rather than opaque paints. The natural grain, figuring and variation within the timber remain visible through the finish.
Always Complete a Test Area First
This is one of the most important rules when working with pigmented oil.
Never rely solely on a colour chart, website photograph or sample made from a different piece of timber.
Osmo recommends a trial application because the condition and characteristics of the wood influence the finished appearance.
Pigment uptake can change according to:
- Wood species.
- Timber density.
- Age of the floor.
- Natural timber colour.
- Moisture content.
- Porosity and dryness.
- Previous treatments or contamination.
- Sanding preparation.
- Application method.
- The topcoat applied afterwards.
If the main floor will be machine-buffed, machine-buff the test area.
If you intend to water-pop the main floor, water-pop the sample.
If you intend to apply along straight planks with a Floor Brush, use the same brush technique on the sample.
Keep the Freshly Sanded Floor Completely Clean
Once final sanding is complete, treat the bare timber as though the finishing process has already started.
Do not walk across the prepared floor in socks or bare feet, and avoid touching the timber unnecessarily with bare hands.
Natural skin oils, moisture and perspiration can contaminate absorbent timber and alter how pigment penetrates.
This can potentially leave:
- Footprints.
- Sock marks.
- Handprints.
- Knee marks.
- Sweat droplets.
- Uneven pigment absorption.
Floor finishing is physical work, and drops of perspiration can easily reach bare timber without being noticed.
Wear clean footwear with clean shoe covers when moving across the final-sanded floor.
Take additional care when kneeling, mixing products or working in warm conditions.
How Should the Floor Be Sanded?
Osmo's standard Polyx-Oil Tints guidance specifies final sanding of wooden flooring to approximately P120āP150.
The complete floor should be sanded progressively and, most importantly, consistently.
Main areas, edges, corners and repaired sections need to finish with a comparable scratch pattern.
Once sanding is complete, vacuum the floor thoroughly using effective dust extraction and protect the surface from contamination.
Do Not Over-Sand the Timber
There is a natural temptation to sand a floor finer and finer because the bare timber feels smoother.
With a penetrating coloured finish, excessively polishing the wood can reduce absorption and change how strongly the pigment develops.
Stay within the preparation recommended for the finishing system and establish the desired colour through the complete test area rather than changing sanding halfway through the project.
Stir Pigmented Oil Thoroughly
Pigments naturally settle within the container during storage.
Stir Polyx-Oil Tints thoroughly before application and continue to stir periodically during use.
This is particularly important on a larger floor where the container may remain open for a considerable period.
What Is the Best Way to Apply Osmo Tints?
Osmo supports application using its Flat Brush, Floor Brush, Microfibre Roller and Oil Finish Applicator Fleece.
For a lighter stained appearance, Osmo also allows the wet Tint to be wiped back with a cloth or white pad within approximately 20 minutes.
In professional flooring work, our preferred approach depends heavily on the flooring pattern.
White Pad / Floor Machine
Our preferred method where maximum control is required, particularly across herringbone, parquet and patterned floors.
The pad allows the pigment to be worked extremely thinly into the surface and makes it easier to control excess product across changing grain directions.
Osmo Floor Brush
Excellent on straight plank flooring because the Tint can be applied and laid off along the length of the boards.
This gives excellent control over the amount of finish and makes it easier to follow the timber grain.
For smaller areas, edges and detailed work, an Osmo Hand Pad Holder with a white pad provides excellent manual control.
Why We Often Prefer a Brush or White Pad
Pigmented finishes expose inconsistencies more readily than clear oils.
A floor brush allows the installer to control how much Tint is placed onto individual planks and to lay the finish off carefully with the grain.
White-pad application works the product into the timber while redistributing excess material across a wider area.
A microfibre roller is also an approved Osmo application tool, but for coloured flooring our preference is generally to use the method that gives the greatest control over pigment distribution for the particular floor being treated.
Applying Osmo Tint with a White Pad
White-pad application can be carried out manually on small areas or mechanically using a suitable rotary floor machine on larger floors.
Our normal professional process is to introduce a small, controlled quantity of Tint and use the pad to work it exceptionally thinly and evenly into the timber.
Avoid flooding the floor.
The pad should be redistributing and working the finish into the surface rather than simply pushing a large pool of product around the room.
Applying Osmo Tint with a Floor Brush
The Osmo Floor Brush is particularly effective on straight plank flooring.
Apply an exceptionally thin coat along the direction of the boards, carefully spreading and laying off the finish with the timber grain.
Work methodically and keep the amount of product consistent from board to board.
Do not leave pools of pigment within bevels, joints or textured areas.
Straight Plank Flooring vs Herringbone
Straight Planks
A Floor Brush is particularly controllable because the product can be applied and laid off consistently along the board direction.
Herringbone & Parquet
White-pad or machine application is generally our preferred method because the blocks continually change direction.
Trying to brush a large patterned area in one direction can create obvious overlaps and directional marks.
How Thin Should Osmo Tint Be Applied?
Exceptionally thinly.
Osmo specifies approximate coverage of up to 30m² per litre for one coat on a smooth, correctly prepared surface.
That high coverage is a useful indication of just how little material the timber actually requires.
How Much Osmo Polyx-Oil Tint Do I Need?
| Pack size | Approximate coverage for one thin coat | Typical use |
|---|---|---|
| 5ml Sample | Small representative test area | Checking colour on the actual timber before committing |
| 0.75L | Up to approximately 22.5m² | Small and medium floors, furniture and joinery |
| 2.5L | Up to approximately 75m² | Larger flooring projects |
Actual coverage varies according to timber porosity, sanding, surface texture and application technique.
How Long Does Osmo Polyx-Oil Tint Take to Dry?
Allow approximately 24 hours under normal conditions with good ventilation.
Osmo bases this figure on approximately 23°C and 50% relative humidity.
Lower temperatures, higher humidity, poor airflow or excessive product can extend drying considerably.
If there is any doubt, give the coloured coat more time.
Airflow Is Critical
Osmo oils cure by oxidation and need access to air.
Provide good ventilation throughout drying without introducing dirt, dust or other contamination onto the freshly treated surface.
Avoid covering the floor while it is drying and curing.
Full cure takes approximately 2ā3 weeks.
How Many Coloured Coats Should Be Applied to a Floor?
For normal wooden flooring, Osmo specifies a maximum of one coloured Polyx-Oil Tint coat followed by the appropriate protective topcoat.
Standard Coloured Flooring System
```Furniture and other appropriate interior timber can have different coating options, including a second coloured coat where Osmo permits it, but flooring should follow the specific floor system.
Important Exception: Polyx-Oil Tints 3040 White
White requires special consideration.
A normal clear oil enriches timber and produces a permanent wet-look effect. On pale wood this often means the natural yellow, gold or warm brown colour becomes more noticeable.
If a clear Polyx-Oil is placed over 3040 White, that warming effect can partially counteract the pale white appearance you were trying to create.
Osmo therefore recommends its white-on-white rule for Polyx-Oil Tints 3040 White.
3040 White Flooring System
```What About Osmo Polyx-Oil Raw 3044?
Osmo Polyx-Oil Raw 3044 is a different product.
Raw contains a much smaller amount of white pigment intended primarily to neutralise the normal wet-look darkening caused by clear oil.
Its purpose is to keep pale timber looking closer to freshly sanded wood rather than create an obvious white-tinted floor.
3040 White
Produces a visible but transparent white tint.
3044 Raw
Uses a smaller amount of white pigment to counteract oil darkening and keep pale wood closer to its untreated appearance.
Raw 3044 is therefore not simply the standard topcoat for 3040 White. Choose the complete system according to the appearance required and test it before treating the main floor.
What If I Want a Much Stronger Colour?
Polyx-Oil Tints are designed to remain transparent and retain the timber grain.
If a much more intensive colour is required, applying increasingly heavy coats of Tint is not the correct solution.
Osmo recommends its more highly pigmented Wood Wax Finish or Oil Stain systems for stronger colour effects.
Optional Professional Technique: Water-Popping
Water-popping can be used professionally to increase pigment uptake and produce a stronger colour effect.
This is not part of the standard Osmo Polyx-Oil Tints Technical Data Sheet, so we treat it as an optional professional technique rather than a manufacturer-required application step.
It should only be used after a complete representative test confirms the result.
WWFS Water-Popping Method
Complete the Final Sanding
Finish the complete floor consistently and vacuum all sanding dust.
Mist Clean Water Evenly
Apply a controlled, even mist using a clean pump sprayer. Avoid puddles and heavy wet areas.
Distribute with a Damp Microfibre Pad
One person can spray while a second immediately follows with a clean damp microfibre applicator to distribute the moisture evenly.
Allow the Timber to Dry Completely
Do not apply Polyx-Oil Tint while residual moisture remains within the timber.
Apply the Tested Tint System
Reproduce exactly the same application method and product quantity used on the approved water-popped sample.
Water causes the timber fibres to raise slightly and can increase pigment absorption.
This can create a richer dark Tint or a stronger pale/white effect depending on the selected colour.
What If Water-Popping Leaves the Timber Feeling Rough?
A slight grain raise is part of what makes the technique increase pigment absorption.
Avoid automatically sanding the floor smooth again before applying the Tint, because doing so can reverse the effect you created.
Equally, avoid aggressive sanding of a dried coloured coat because this can remove pigment and create pale patches.
Can I Water-Pop Only to Make White Look Whiter?
Water-popping can increase the absorption of white pigment, so it can make the white effect more pronounced.
But it also changes the character and texture of the surface.
Always compare water-popped and normally prepared samples side by side before deciding which appearance is preferable.
Common Osmo Tint Problems
Patchy Colour
Common causes include inconsistent sanding, uneven pigment distribution, surface contamination, varying timber absorption or allowing sections to dry before they are blended.
Dark or Heavy Areas
Usually caused by excess product being left on the timber or repeated overlap onto an area already beginning to dry.
Pale Areas after the Next Coat
The coloured coat may not have been fully dry and the subsequent application may have disturbed or pulled pigment from the surface.
Edges Look Different from the Centre
Check for differences in sanding, application quantity and the amount of Tint worked or wiped from the floor.
White Finish Looks Warmer after Topcoating
A clear oil can enrich the natural timber colour. For 3040 White, use Osmo's white-on-white system where maintaining the pale white appearance is required.
Visible Brush Lines on Herringbone
Patterned floors continually change grain direction. A white-pad or rotary-machine application method is usually easier to control than attempting to brush the entire pattern in one direction.
Oil Is Still Sticky after 24 Hours
Common causes include excessive application, poor ventilation, low temperature or high humidity.
Improve airflow and allow additional drying time rather than applying another coat prematurely.

A single-component pigmented hardwax-oil system with approximately 24-hour drying for the coloured coat.
Bona Craft Oil 2K
A two-component penetrating oil mixed with hardener. It can form a standalone oiled finish or be used beneath approved Bona Traffic lacquer systems.
See our Bona Craft Oil 2K guide for mixing, water-popping, buffing and topcoat guidance.
Cleaning & Maintaining an Osmo-Tinted Floor
Once the complete Polyx-Oil system has dried and cured, maintain the floor as an Osmo hardwax-oiled surface.
Vacuum or dry-clean regularly to remove abrasive grit.
Damp cleaning should be carried out with an appropriate Osmo floor-care product and a well-wrung mop rather than saturating the timber.
For a complete general maintenance system, the Osmo Floor Maintenance Kit provides compatible cleaning and refreshing products for Polyx-Oil-treated flooring.
Where a floor becomes dull or lightly worn, an appropriate Osmo Maintenance Oil can be used following correct cleaning, preparation and colour/sheen matching.
Oil-Soaked Cloth Safety
Cloths, pads and other absorbent materials contaminated with drying oils can generate heat while curing.
Follow the safety instructions supplied with the product.

Frequently Asked Questions
How many coats of Osmo Polyx-Oil Tint should I apply to a floor?
For most flooring colours, apply one thin coloured Tint coat followed by the appropriate Polyx-Oil topcoat. Polyx-Oil Tints 3040 White is an exception and can use 3040 White again as the second coat under Osmo's white-on-white system.
How long does Osmo Polyx-Oil Tint take to dry?
Approximately 24 hours under normal conditions with good ventilation. Cooler temperatures, higher humidity, poor airflow or heavy application can extend drying.
How much does one litre cover?
Up to approximately 30m² per litre for one thin coat on a smooth, correctly prepared surface.
What sanding grit should I use before Osmo Tints?
Osmo's standard Polyx-Oil Tints guidance specifies approximately P120āP150 final sanding for wooden flooring. Maintain the same preparation across the complete floor.
Can I apply Osmo Tints with a white pad?
Yes. Osmo permits a cloth or white pad for wiping the Tint back to create a lighter stained effect. WWFS also commonly uses controlled white-pad application on professional flooring projects, particularly herringbone and parquet.
Can I apply Osmo Tints with a floor machine?
White-pad machine application is a useful professional method for distributing pigmented oil exceptionally thinly and consistently. Always test the exact machine, pad and application process before treating the complete floor.
Can I use an Osmo Floor Brush?
Yes. A Floor Brush is particularly effective on straight plank flooring because the finish can be applied and laid off consistently in the direction of the timber grain.
Should I use a roller?
Osmo approves its Microfibre Roller for Polyx-Oil Tints. On coloured flooring, WWFS generally chooses the application method that provides the best control for the floor pattern, often a Floor Brush on straight planks or white-pad application on patterned floors.
Can I apply two coloured Tint coats?
For normal flooring colours, Osmo specifies a maximum of one coloured Tint coat followed by the appropriate topcoat. 3040 White has a specific exception allowing the white-on-white system.
Why has my Osmo Tint gone patchy?
Common causes include inconsistent sanding, contamination, heavy application, poor mixing, different timber absorption or allowing areas to begin drying before they are properly blended.
Why is pigment coming off when I apply the next coat?
The coloured coat may not be fully dry. Allow additional drying time rather than continuing to work over a surface where the pigment is still moving.
Can sweat or footprints affect a tinted floor?
Yes. Moisture and skin contamination on bare absorbent timber can affect pigment penetration. Keep final-sanded timber clean and use clean footwear with suitable shoe covers.
Can I water-pop before applying Osmo Tints?
It can be used as a professional technique to increase pigment uptake, but it is not a standard step within the Osmo Polyx-Oil Tints Technical Data Sheet. Complete a full representative trial first and apply the water evenly across the complete area if the technique is selected.
Should I put clear Polyx-Oil over 3040 White?
Not automatically. Clear oil can warm the timber beneath the white Tint. Osmo recommends the white-on-white system using 3040 White as the second coat where maintaining the pale white appearance is important.
Is 3044 Raw the same as 3040 White?
No. 3040 White creates a visible transparent white tint. Raw 3044 contains a much smaller amount of white pigment designed primarily to reduce the normal darkening effect of clear oil and retain a nearly untreated appearance on pale timber.
What if I want a much darker or stronger colour?
Do not simply apply Polyx-Oil Tints more heavily. Osmo recommends its more intensively pigmented Wood Wax Finish or Oil Stain systems where a stronger colour is required.
Can Osmo Tints be used on herringbone?
Yes. Pay particular attention to sanding consistency and pigment distribution. WWFS generally prefers white-pad application on herringbone because the timber grain continually changes direction throughout the pattern.
How long does the complete finish take to cure?
Osmo advises approximately 2ā3 weeks for the surface to become fully cured. Avoid covering the floor and treat it carefully throughout the early curing period.
WWFS Final Recommendation
Colour, coverage, drying and absorption vary according to timber species, natural colour, sanding preparation, porosity, temperature, humidity and application technique. Always complete a representative test using the exact proposed finishing system and refer to the latest Osmo Product Information and Safety Data Sheets before application.
