Compare three different professional ways to colour a wooden floor: a fast-drying penetrating stain, a pigmented hardwax oil or a two-component coloured oil.
```Morrells Light Fast Wood Stain is a professional fast-drying alcohol-based stain designed to colour interior timber while retaining strong grain definition.
It is particularly effective on wooden flooring because the colour penetrates the timber rather than forming the final protective surface. Once the stain has dried, it is sealed beneath a compatible lacquer, hardwax oil or other approved finishing system.
The advantage of this approach is flexibility: the stain determines the colour, while the finishing system above it can be selected according to the required durability and sheen.
The challenge is speed. Morrells Light Fast Stain dries quickly, so poor wet-edge control, inconsistent sanding, heavy deposits or overlapping onto partially dry stain can create visible colour variation.
What Is Morrells Light Fast Wood Stain?
Morrells Light Fast Wood Stain is a professional solvent-based, alcohol-based interior wood stain designed to produce strong colour and excellent grain definition.
It is suitable for wooden floors, furniture, cabinetry, interior doors, trims and other internal timber.
Unlike a coloured hardwax oil, the stain itself is not the protective flooring finish. It colours the timber first and must then be sealed beneath a compatible finishing system.
What Does āLight Fastā Mean?
Morrells uses lightfast pigments to improve resistance to colour fading caused by light exposure.
It does not mean that the colour or timber is permanently immune to UV or natural ageing.
Real timber can still change over time, and areas beneath rugs or furniture may age differently from exposed areas.
Always Complete a Test Area First
This is essential with any wood stain.
The same Morrells colour can look significantly different depending on:
- Wood species.
- Natural timber colour.
- Timber density.
- Age of the floor.
- Porosity.
- Final sanding grit.
- Application method.
- Number of stain applications.
- The sealer and topcoat applied afterwards.
WWFS stocks Morrells Light Fast Stain in 100ml samples specifically so the complete finishing system can be tested before committing to a larger quantity.
Keep the Final-Sanded Timber Clean
Once final sanding is complete, avoid contaminating the bare timber.
Do not walk across it in bare feet or socks and avoid touching absorbent timber unnecessarily with bare hands.
Sweat, skin oils, water droplets and other contamination can change the way a stain penetrates the surface and may become more visible after colour is applied.
How Should the Floor Be Sanded?
The entire floor needs a consistent sanding sequence before staining.
Coarse scratches can hold extra stain and appear darker, while areas finished considerably finer may absorb less colour.
The exact final sanding specification depends on the timber and finishing system, but the most important rule is consistency.
Main floor areas, edges, corners and repaired sections should all be blended to the same final surface.
Fill Before the Final Sanding Stage
Suitable fine gaps and minor defects should be filled before the final sanding sequence.
Once the filler has dried, sand the complete floor consistently so that filler residue is removed from the timber surface before staining.
Do not spread filler after the floor has already received its final stain-ready sanding unless the system specifically requires it.
Vacuum Thoroughly
Remove sanding dust from:
- The main floor.
- Board joints.
- Edges and corners.
- Skirting lines.
- Doorways.
- Adjacent surfaces where dust could fall back onto the floor.
The timber should be clean, dry and free from oil, wax, silicone, polish and other contamination before staining.
Stir or Shake the Stain Thoroughly
Colour components can settle during storage.
Mix the stain thoroughly before application and continue to mix periodically during a larger flooring project so the colour remains consistent.
Our Preferred Floor Application Method
Morrells approves brush, cloth and mohair-pad application for Light Fast Stain.
For larger flooring areas, our preferred WWFS method is:

This gives good control over the amount of stain applied while the cloth removes heavy deposits and evens the colour.
Why Remove the Excess Stain?
Morrells specifically advises removing as much excess stain as possible.
Light Fast Stain is designed to colour the timber ā it should not be allowed to create a heavy surface film.
Heavy residue can:
- Dry unevenly.
- Create darker patches.
- Produce lap marks.
- Reduce adhesion of the subsequent sealer or lacquer.
Maintain a Wet Edge
Morrells Light Fast Stain dries extremely quickly.
This is an advantage for productivity, but it means large floors need to be planned carefully.
Work in areas that can be fully stained and laid off before the visible edge begins to dry.
Avoid returning with fresh stain over an area that has already started drying because the overlap can absorb more colour and create a darker band.
How Large an Area Should I Stain at Once?
There is no fixed square-metre rule because room temperature, timber porosity and the number of people working all affect the practical working area.
The important point is that the stain should remain workable long enough to apply, lay off and blend the section properly.
On a large floor, two experienced people can work effectively together: one applying and one laying off/removing excess.
Applying Stain to Straight Planks
Straight plank flooring is generally the easiest format to control.
Work predominantly with the board direction and natural grain.
Use the Floor Brush to ensure bevels and joints receive colour without allowing the stain to pool within them.
Follow immediately with clean cloths, working along the grain to remove excess and blend the appearance.
Applying Stain to Herringbone & Parquet
Herringbone and parquet require additional care because the timber grain changes direction throughout the pattern.
Avoid attempting to brush a large patterned area in one fixed direction.
Work in smaller manageable sections and pay close attention to the direction of individual blocks when laying off excess.
Clean lint-free cloth or a suitable professional stain pad can provide useful control on patterned flooring where brush overlaps would be difficult to manage.
How Many Coats Can Be Applied?
Morrells Light Fast Stain can be applied in one or two coats depending on the required colour intensity.
In many flooring applications, one controlled coat provides the required colour.
If a second coat is being considered, complete the full two-coat test system first.
Allow the first application to dry and continue to remove excess rather than building a heavy film.
How Quickly Does Morrells Light Fast Stain Dry?
| Property | Typical figure |
|---|---|
| Touch dry | Approximately 15ā30 minutes at 18Ā°C |
| General recoat | Approximately 15ā30 minutes at 18Ā°C |
| Wood flooring sealer / topcoat | Minimum approximately 2 hours at 18Ā°C |
| Coverage | Approximately 8ā12mĀ²/L per coat |
| Application methods | Brush, cloth, mohair pad, spray or dip |
| Use | Interior timber only |
Drying times are approximate.
Cooler temperatures, poor ventilation, a less absorbent timber or heavy application can increase drying time.
How Much Stain Do I Need?
Coverage is approximately 8ā12mĀ² per litre, per coat.
Actual consumption depends on the timber, sanding quality and amount removed during the laying-off process.
| Pack size | Approximate coverage per coat | Best suited to |
|---|---|---|
| 100ml Sample | Small test area | Testing colour and the complete finishing system |
| 1L | Approx. 8ā12mĀ² | Smaller floors, stairs, furniture and joinery |
| 5L | Approx. 40ā60mĀ² | Larger floors and professional projects |
Does Morrells Light Fast Stain Raise the Grain?
Morrells describes Light Fast Stain as non-grain raising.
This is one of the practical advantages of its alcohol-based formulation compared with some water-based colouring systems.
The floor still needs correct initial preparation, but the stain itself is designed to colour the timber without introducing the same degree of fibre raise associated with water.
Which Protective Finish Should Go over the Stain?
Light Fast Stain must be protected by a compatible finishing system.
For the most directly supported Morrells flooring specification, we recommend staying within the Morrells Induro system.
Domestic & General Flooring
XL1 is a ready-to-use single-pack waterborne polyurethane lacquer with no catalyst or pot-life restrictions.
Busy Domestic & Commercial Flooring
XL2 is designed for higher traffic and provides increased chemical and mechanical resistance.
Why Use a Sealer after Staining?
Morrells Induro GP Sealer forms the link between the stained timber and the Induro lacquer system.
It helps seal the stained surface, promotes a consistent lacquer build and enhances clarity and timber character.
Can Other Lacquers Be Used?
Morrells Light Fast Stain is used beneath a variety of professional finishing systems, but cross-brand combinations require more testing.
If using a different professional waterborne lacquer or hardwax-oil topcoat:
- Remove all excess stain.
- Allow the stain to dry fully.
- Check compatibility with the finishing manufacturer.
- Complete the exact full-system test on the actual timber.
Clear finishes can alter the appearance of the stained timber, so never approve a cross-brand system from the dry stain alone.
Light Fast Stain vs Osmo Polyx-Oil Tints
These are fundamentally different colouring methods.
Morrells Light Fast
A dedicated fast-drying stain that colours the timber first.
The protective sealer, lacquer or compatible finishing system is applied afterwards as a separate stage.
Osmo Polyx-Oil Tints
A pigmented hardwax-oil treatment where colour is incorporated into the oil/wax finishing system.
Application is slower and relies heavily on controlled thin-coat application and the correct Osmo topcoat.
For full application guidance, see our Osmo Polyx-Oil Tints guide.
Light Fast Stain vs Bona Craft Oil 2K
Bona Craft Oil 2K is also very different from a traditional stain.
Craft Oil 2K is a two-component penetrating oil treatment, available in colour options, whereas Morrells Light Fast colours the timber before a separate protective finish is applied.
See our Bona Craft Oil 2K guide for the complete application process.
Common Problems & How to Avoid Them
Patchy colour
Usually associated with inconsistent sanding, uneven absorption, letting one area dry before adjoining stain is blended, or failing to remove excess consistently.
Dark overlap marks
Caused by bringing fresh stain back over a partially dried section.
Reduce the size of each working area and maintain a wet edge.
Very dark joints or bevels
Excess stain may have collected within the joints.
Apply less product and remove surplus immediately.
Edges look different from the centre
Check that the edge-sanding sequence and final grit match the main floor and that the cut-in stain was blended while still wet.
Lacquer adhesion problems
Heavy stain residue can behave like a surface film.
Remove excess thoroughly and allow the floor to dry fully before sealing.
Colour changes after the topcoat
This is normal to a degree.
Clear sealers and lacquers can increase depth and warmth. This is why the final decision should be based on a complete test system.
Safety & Ventilation
Morrells Light Fast is a professional solvent-based stain.
Use it in well-ventilated interior spaces and follow the current Safety Data Sheet, label instructions and appropriate PPE requirements.
Keep the product and solvent-contaminated materials away from ignition sources and dispose of used materials safely.

Frequently Asked Questions
Is Morrells Light Fast Stain suitable for wooden floors?
Yes. Morrells specifically formulates the range for interior wooden substrates including floors. The stained timber must then receive a compatible protective finishing system.
How fast does Morrells Light Fast Stain dry?
It is typically touch dry in approximately 15ā30 minutes at 18Ā°C. For flooring, allow a minimum of approximately two hours before applying a sealer or topcoat.
How much does one litre cover?
Approximately 8ā12mĀ² per litre, per coat, depending on the timber, sanding and application method.
How many coats can I apply?
Morrells specifies one to two coats. Test the complete system first and avoid creating a heavy film on the timber.
Do I have to wipe the stain off?
Morrells advises removing excess stain. This helps even the colour and avoids creating a surface film that could reduce adhesion of the subsequent lacquer.
Can I apply it with a brush?
Yes. Morrells approves brush application. For floors, WWFS commonly uses an Osmo Floor Brush followed immediately by clean absorbent cloths to remove excess and lay off the stain.
Why does the stain look patchy?
Common causes include inconsistent sanding, working too large an area, losing the wet edge, unequal stain removal or timber with naturally different absorption.
Does Morrells Light Fast raise the grain?
Morrells describes Light Fast Stain as non-grain raising.
Does āLight Fastā mean the colour will never fade?
No. Lightfast pigments improve resistance to fading, but timber and finishes can still change through natural ageing and prolonged light exposure.
Can I use it on engineered flooring?
Yes, where the engineered floor has a genuine sandable timber wear layer suitable for site staining and finishing.
Can I stain herringbone?
Yes, but work in smaller controlled sections because the grain direction changes throughout the pattern and the stain dries rapidly.
What should go over Morrells stain?
For the fully matched Morrells flooring system, use Induro GP Sealer followed by Induro XL1 or XL2 according to the traffic and durability required.
Can I apply hardwax oil over Morrells Light Fast Stain?
Compatible cross-brand systems can be possible, but the stain must be fully dry and all excess removed. Always complete a representative full-system test and confirm compatibility with the finishing-product manufacturer.
Will the lacquer change the stain colour?
It can. Clear sealers and lacquers may increase depth and warmth, so always judge the final colour after the complete finishing system has been applied to the test area.
Our Final Recommendation
Colour, coverage and drying vary according to timber species, natural colour, sanding sequence, porosity, temperature, ventilation and application method. Always test the complete stain, sealer and finishing system on the actual timber before treating the full floor, and refer to the latest Morrells Technical and Safety Data Sheets before professional application.
