Odourtak W Floral is a ready-to-use water-based fogging solution for fire and smoke odour. It is fogged into a space after cleaning, so the micro-droplets follow the same path the smoke took - into cavities, behind skirtings, through porous linings - and neutralise the odour molecules left behind. This listing is the 1 litre bottle.
W is the water-based half of the Odourtak range, and it is the one Actichem specify for buildings people are still using - rooms, offices and halls. It carries the lighter of the two hazard signal words. For a stripped-out or unoccupied building, the solvent-based Odourtak SV is the harder-working option. Read the fogging note below before you choose a machine.
Product description
Water based enzyme odour control for fire and smoke odour. Odourtak W Floral is a water-based formulation powered by Elimotech chemistry for rapid neutralisation of odours caused by smoke and soot. Elimotech reacts with and neutralises mal-odours at a micro-molecular level, enabling quick and permanent elimination of trapped, embedded and air-borne odours.
Even a thorough disinfection and wash down of an area will not remove all odour molecules. Micro smoke odour particles exist in the air, trapped in fabrics, carpets and porous materials. In addition to a cleaning routine, you need an Odour Control Strategy.
The Floral fragrance is best suited to smoke and soot odours from plastic and synthetic material fires. It is intended for spaces that are still occupied, such as rooms, offices and halls.
W or SV - which one for this job?
This is the decision that matters most, and it is about the building, not the smell.
| Odourtak SV | Odourtak W | |
| Base | Solvent | Water, pH 7.5 |
| Equipment | Thermal (hot) fogger | See the fogging note below - Actichem's own material is inconsistent |
| Intended space | Non-inhabited - attics, sub-floors, stripped-out buildings | Inhabited - rooms, offices, halls |
| Hazard signal word | Danger | Warning |
Both are ready to use, both are applied at the same rate, and both use the same Elimotech chemistry. The difference that matters is the building: SV is for spaces nobody is living in yet, W is for spaces still in use.
Which fogger does Odourtak W go through?
Check this before you order. Actichem's own material is not consistent on the point, and we would rather show you the conflict than quietly pick a side.
- The detail on Actichem's product page describes Odourtak W as "Cold/Wet Fogging Optimised" and states it is formulated to be applied through cold and wet fogging equipment.
- The summary line on that same page, and the printed label on the bottle we ship, both describe it as a thermal fogging solution.
What is not in dispute: Odourtak W is water-based, it is the Odourtak specified for occupied spaces, and it is applied at 0.5-1.5 ml per m³. Cold and wet fogging is the documented application and is the safe assumption. If you intend to run it through a thermal fogger, ring us or Actichem first and confirm it against your specific machine. We have asked Actichem to clarify and will update this page when they do.
Citrus or Floral?
Actichem match the fragrance to the fuel that burned:
- Citrus - smoke odours from protein, paper and timber fires.
- Floral (this product) - smoke odours from plastic and synthetic fires.
On a mixed-fuel fire, most operators pick the fragrance that matches the dominant source and treat the remainder on the second pass.
Application
Applied by fogging - see the fogging note above before you choose a machine. Do not dilute and do not mix with other chemicals - it is supplied at working strength.
- Rate: 0.5-1.5 ml per m³ of air or room space.
- Worked example: a room 4 m x 5 m with a 2.4 m ceiling is 48 m³, so 24-72 ml for that room. This 1 litre pack covers roughly 660 to 2,000 m³ depending on the rate you run.
- Dwell: keep the space closed for a minimum of 30 minutes.
- Ventilation: ventilate for 1 hour before extended occupation.
- Pre-test in an inconspicuous location before treating the whole area.
- Cover or remove food and moisture-sensitive items before fogging.
Safety
Odourtak W carries the signal word Warning. Actichem specify protective clothing and respiratory protection: a Type A Class 1 or 2 gas filter to AS/NZS 1715/1716 (brown cartridge), or a CF22 A2 combined filter which also covers particles and micro-organisms.
Important: Carpet Cleaners Warehouse does not currently stock an AS/NZS 1716 approved Type A gas filter. The 3M 60921 Organic Vapour/P100 cartridge we stock is NIOSH-approved, which is the United States scheme and not the same certification. If your site or safety management system requires AS/NZS 1716 filters for fogging work, source them separately, and ring us if you want help identifying an equivalent. We would rather say this plainly than have someone fog a job in the wrong cartridge.

Frequently asked questions
Can I use this in an occupied building?
Yes - that is what W is for. It is water-based and specified for inhabited spaces such as rooms, offices and halls. Still close the space for the dwell period and ventilate before people return.
Do I dilute it?
No. It is supplied ready to use, and Actichem specifically say not to dilute it or mix it with other chemicals. The control you have is the dose per cubic metre, not the strength.
How much do I need for a job?
Work out the room volume in cubic metres and multiply by 0.5 to 1.5 ml. Light odour sits at the bottom of that range, heavy fire damage at the top. Measure the volume rather than guessing from floor area - a warehouse and a bedroom with the same footprint are very different jobs.
Will it work if I have not cleaned first?
Not properly. Fogging is the last step in an odour control strategy, not a substitute for one. Soot and residue left on surfaces keep generating odour, and no fogging product will out-run that.
Cold fogger or thermal fogger?
Actichem's own material is inconsistent on this for Odourtak W - see the fogging note above. Cold and wet fogging is the documented application and the safe assumption. If you plan to run it hot, confirm with us or with Actichem against your specific machine before you do.
Does the fragrance mask the odour?
No. The Elimotech chemistry neutralises odour molecules rather than covering them. The fragrance is there to match the odour type being treated, which is why Citrus and Floral are matched to different fire fuels.
What we see in the field
[Technician's Note - replace before publishing: two to four sentences of first-hand CCW field experience relevant to this product. A pattern you see, a mistake customers make, or something learned from servicing or selling it. Not spec repetition, not a sales pitch, not invented.]
Not sure whether this job calls for SV or W, which fogger to run it through, or how much you need for the volume you are treating? Ring Carpet Cleaners Warehouse before you order. Fogging the wrong product into an occupied building is an expensive mistake and it is entirely avoidable.
