Ready to use highly efficient disinfecting mould cleaner with multiple uses and application methods. Suitable for light, medium and severely contaminated surfaces.
READY-TO-USE – FOAMABLE SOLUTION FOR MOULD CLEANING AND SURFACE DISINFECTION
New Sanosil SD7 hydrogen peroxide (H2O2) disinfectant cleaner has been developed with state-art-the-art technology. SD7 was primarily developed as a disinfecting mould-cleaner for the damage restoration industry. The main objective with SD7 was to develop userfriendly disinfectant with very efficient cleaning capabilities combined with strong disinfection power.
Sanosil SD7 consists of a 7.9% H2O2 ready to use solution with a specially formulated surfactant package boosting the cleaning power of SD7. SD7 can tackle both mild and severe mould-growth and is very pleasant to work with.
• Excellent wetting effect on all surfaces – the products ability to penetrate semi-porous to porous surfaces like wooden constructions, concrete, plaster and more to deep-clean, loosen and inactivate and remove mould including its roots, is unique to this product. The low surface tension of SD7 allows the product to efficiently, via capillary action, to pull itself into joints and cracks i.e. wooden constructions and more.
• SD7 foams profusely (like Serum 1000 and Serum SBC) on contact with the mould enzymes showing the user where the living mould is present.
• Due to a state-of-the art surfactant package the cleaning abilities of SD7 are extremely good.
• SD7 can be applied as liquid but also as a foam which makes SD7 stick to surfaces for longer contact times and improved cleaning capabilities.
• When you spray/apply SD7 as a foam, you do NOT create any aerosols, which is nice and safe for the user. Surface foam is created with a special foam sprayer. We have at NAC several foam sprayers in our product portfolio.
• SD7 can be mixed with our new liquid SFS polymer/resin agent to spray as a thick foam into inaccessible cavities/confined spaces to inactivate mould and fix (bind) the inactivated mould spores to the surface. The SD7/SFS foam is very stable and thick, but still has the ability to fill cracks and joints in cavities/confined spaces. The thick and stable foam is being produced by a special foamsprayer, see details in this brochure.
• SD7 can also be used efficiently in a ULV cold-fogger for disinfection in larger rooms.
• And there are many more nice features about this product.
Sanosil SD7 is a ready-to-use, fast-acting, surface disinfectant and mould control agent. It is based on a formulation containing enhanced hydrogen peroxide and has excellent wetting properties, even on water-repellent or slightly greasy surfaces. This allows fast and deep penetration even into dense mould structures. When combined with suitable foam sprayers, Sanosil SD7 can be foamed, which allows low-aerosol application with optimised surface coverage.
Low-odour hydrogen peroxide is used as the active ingredient. It is also stabilised and its disinfecting effect is enhanced several times over by adding surfactants. These substances have a synergistic effect and combine with the hydrogen peroxide to form a highly effective biocidal mixture. This combination significantly increases the disinfecting effect of the hydrogen peroxide.
After application, the active ingredient, hydrogen peroxide, completely decomposes into water and oxygen. No flammable or unpleasant smelling vapours are released. This makes it safe to use in living rooms and bedrooms.
EFFECTIVE AGAINST MOULD TOXINS
Moulds can affect health not only due to the allergy-inducing surface proteins on the mycelia and spores, but potentially also through the formation of strong toxins. These mycotoxins are relatively stable and can enter the body through food as well as through the air.
However, mycotoxins are highly susceptible to Sanosil SD7 and are quickly oxidised by it.
SD7 also denatures the allergenic surface proteins on mould components. This provides Sanosil SD7 with a special advan-

tage in terms of its effectiveness and makes it superior to many other products.
No matter which disinfectant is used, the disinfection effect is always stronger if the surface to be disinfected is cleaned as thoroughly as possible beforehand. The spray-and-wipe disinfection method, or applying the disinfectant with a moistened wipe is significantly more effective than simply spraying it onto the surface. Spraying alone (especially with a handheld sprayer without a foam nozzle) can result in gaps in effectiveness and therefore must be avoided.

FOR SUCCESSFUL DECONTAMINATION, YOU MUST TACKLE THE ROOT CAUSE!
Even the best mildew remover cannot guarantee lasting success without eliminating the cause of the infestation. Mould spores need moisture to grow. The cause of an increased presence of moisture must therefore be determined and remedied. The two most common causes of mould growth in buildings are A excessive humidity (usually in combination with insulation deficiencies, which then leads to the wi-despread “grey corners”) and B furniture positioned too close to the outside walls.
HUMIDITY
If there is a relative humidity over 65% – measured 1 metre above the floor in the middle of the room at a room temperature of 20°C in autumn/winter – there is a risk of mould due to condensation.
If the surface temperature in a poorly insulated corner, for example, drops below 13°C under “normal” conditions (20°C, 60–65% relative humidity), condensation can cause mould to form.
FURNITURE PLACED AGAINST EXTERNAL WALL
Large items of furniture, such as cupboards etc. that are placed against an external wall, should be placed at a distance of 10-15 cm (one fist width) from the wall.

The oxygen released by hydrogen peroxide attacks the cell walls of the microorganisms. Through oxidation (cold combustion), the cell walls are denatured and destroyed.
The effect is supported by complexing agents and surfactants, which bind calcium ions while also masking metal ions. This severely weakens the surfaces of the microorganisms and makes them highly susceptible to the hydrogen peroxide’s oxidising effect.

Sanosil SD7 is a ready-to-use cleaning and disinfecting agent with exceptional effectiveness against mould and other microorganisms. It is based on the proven Sanosil hydrogen peroxide formulation and releases no flammable or malodorous fumes. Sanosil SD7 is odour neutral.
SD7 is suitable for use with high microbiological loads and increased requirements. The fast and reliable effectiveness against moulds combined with simple and safe handling has been repeatedly tested and confirmed under laboratory conditions and in practice. Sanosil SD7 also breaks down completely into water and oxygen after use. This means that the SD7 can also be used in sensitive areas such as bedrooms and children’s rooms.

Remove wallpaper and apply SD7 to the substrate.
Remove the wallpaper/felt and apply SD7 to the substrate.
Paint and varnish are organically based and can form a breeding ground for mould. Check whether the paint/varnish is intact and that it is only a matter of light/loose surface mould. If this is the case use SD7. If the paint/varnish is heavily attacked by mould and the structure is destroyed, remove the paint/varnish and apply SD7 to the substrate.
Remove all visible mould-contaminated plaster and apply SD7 to the substrate.
Before any cleaning/disinfection with Sanosil SD7, you must assess whether the mould attack has penetrated so deeply into materials such as e.g. plaster and woodwork, that the integrity and structure of the material is destroyed. If this is the case, the material should be discarded and replaced with new.
Sanosil SD7 should only be used as the only cleaning method if it is estimated that the mould attack is superficial.
If it is considered that the mould attack is deeper, a cleaning with Sanosil SD7 can be combined, if necessary, with a Serum 1000 cleaning or mechanical cleaning, such as e.g. planing, grinding/milling or media/sandblasting, etc.
SPREADING:
1 litre: 15-20 m2 on light mould attacks.
1 litre: 7-10 m2 on moderate-severe mould attack.
1. Prior to any treatment with Sanosil SD7, the cause of the mould growth should be located and found. To control mould, you must control the moisture. The cause of mould growth is usually elevated moisture values. Locate the cause and, if possible, ensure that it is rectified.
2. When remediating mould on woodwork/wooden structures, bring the moisture percentage below approx. 15%.
3. Ensure the safety of the building’s occupants and avoid cross-contamination of mould spores from dirty work areas to clean inhabited areas by enclosing the work area with dust walls, e.g. Zipwall. If possible or if necessary, establish underpressure or overpressure using HEPA air cleaners, axial or radial fans, etc.
4. Clean the work area before starting chemical treatment with Sanosil SD7. Remove the infested construction waste, insulation, masonry and concrete remains, etc. Sweep and vacuum the area with an industrial vacuum cleaner.
5. Mould remediation should be carried out as the last step in a remediation process in mould-affected areas.
Carry out your own quality control continuously during your remediation work with PRO-Clean rapid protein test or SystemSure Plus luminometer with UltraSnap surface ATP test.
Sanosil SD7 is ready to use and does not need to be diluted.
1. The surface must be vacuumed thoroughly with a HEPA vacuum cleaner to remove loose mould.
2. Pour Sanosil SD7 into a 5 or 1.25 liter quality pressure sprayer, e.g. NAC Sanosil pressure sprayer. When treating larger areas, it is recommended to use NAC’s electric magnetic pump sprayers, Power Sprayers.
3. Spray the mould infested area generously with SD7 which immediately reacts with the mould by producing a white foam. Let the SD7 work for 1-2 minutes.
4. Loose surface mould will boil up in the foam. Underlying mould stains (bio-film) will gradually dissolve in this process.
5. Scrub/treat all surfaces thoroughly with a nylon floor scrubber or nylon hand brush until the mould infestation is visibly loosened from the surface.
6. Wait at least 20 min. and then reapply SD7 to the areas that foamed. Repeat the process until it no longer foams.
7. When all areas have stopped foaming, wait until the surfaces are dry. Set up any dehumidifier to speed up drying of the area.
8. When the area is dry, HEPA vacuum EVERY cm2 very thoroughly to remove spores/fungal biomass. Smooth non-porous surfaces can also be cleaned of spores/fungal biomass with special microfiber cloths.
9. Own quality control. If necessary, check the cleanliness of the surface with PRO-Clean rapid test (rapid protein residue test) or SystemSure Plus luminometer with UltraSnap (surface ATP test) or similar. If the test is positive, repeat cleaning.
10. Continue to keep the area contained and protect the mould-remedied area from outside sources of contamination. Continue to use HEPA air purifiers, etc.
11. External control can be carried out after approx. 24 hours.
Note: When transferring SD7 into spray bottles, a label containing information about the contents must be attached to the outside of the container. We can provide suitable labels on request.
Thoroughly clean the surface to be treated with a suitable cleaning agent. The cleaner the surface, the better the disinfection effect.
Put on gloves. Dampen a wipe with undiluted Sanosil SD7. Dosage on smooth surfaces: 30–50 ml/m2.
Alternative: Use a spray bottle with foam nozzle, apply foam to surface, spread with wipe.
Let the agent take effect and dry.
Wet the surface to be disinfected with the cloth so that an even, continuous, moist film remains. Avoid puddles. If drops or puddles remain on smooth surfaces, spread them with the wipe.
Note: When spraying directly with a device, make every possible effort to avoid aerosol formation. (Use a spray bottle with a foam nozzle.) Suitable respiratory protection must be worn for larger-scale applications (beyond typical household use) in order to avoid irritation of the respiratory tract.
Attention: When using professional spraying equipment, aerosols are always produced, which may be harmful. For this reason, you should always wear a full-face respirator when carrying out spraying work to prevent irritation of the respiratory tract and eyes. (Respiratory protection with gas filter (against hydrogen peroxide) Filter type: ABEK-P3)
Thoroughly clean the surfaces to be treated with a suitable cleaning agent. The better the cleaning, the more effective the disinfection. Pour the required amount of Sanosil SD7 into the storage tank of a sprayer (e.g. Sanosil Stream, C150, pressure sprayer with a compressed air connection, airless sprayer, etc.). Put on protective equipment (full-face respirator with ABEKP3 filter and gloves).
Select the finest possible atomisation method and spray the surfaces to be disinfected so that a slightly moist surface is created all over them. (Similar to a fogged bathroom mirror when showering.)
Reference value: 30 – 50 ml/m2. Avoid drops/puddles and runs.
Prevent any aerosols – which are inevitably formed when spraying disinfectants – from reaching any parts of the room containing unprotected persons.
Let the product soak in. For safety reasons, no one should enter the room without protective equipment for up to 2 hours after the disinfectant has been sprayed. (Maximum workplace concentration for hydrogen peroxide in the air: 1 ppm)
If the MAC value is too high, increase the waiting time or thoroughly ventilate the room. There must not be any disinfectant odour or irritation of the respiratory tract/eyes.
Note: The finer the droplets, the better the wetting. Avoid drops/puddles and runs caused by applying too much disinfectant. If necessary, wipe the affected areas with a wipe before they dry.
Ideal for mould treatment on hard-to-reach surfaces, cavities, intermediate spaces, niches, etc.

The Sanosil SFS system is an alternative for mould remediation in places where it is not possible to use the HEPA sandwich method to remove the mould material, due to lack of access or limited space.
Sanosil SFS is a powerful foaming surfactant concentrate with modified acrylic resins for delayed film formation. It forms a biocidal active foam solution when applied together with the disinfectant Sanosil SD7. Bacteria and mould are killed during the liquid phase. Once the foam has dried, a film forms which traps dead mould spores and mycelium com-ponents and fixes them on the surface. This means that no more spores or mould components can enter the room air.
The classic mould removal method, the HEPA Sandwich Method, consists of: 1. thorough HEPA vacuuming; 2. chemical or mechanical removal of mould (or both methods in combination); 3. final thorough HEPA vacuuming of remaining mould material.
For technical and economic reasons, it is sometimes not possible to optimally implement the classic method of mould control (mechanically removing the dead biomass and inactivating the mould). For example, in the case of mould infestation on/in angled surfaces or cavities.
The solution of Sanosil SFS and Sanosil SD7, foamed using a suitable foaming device, is sprayed onto the infested surfaces or pressed into cavities. The biocidal agents eliminate mould components, spores and bacteria. In addition, mould toxins and proteins that trig-ger allergies as well as MVOCs (which are responsible for musty smells) are eliminated/broken down by oxidation.

The dead biomass is encapsulated and fixed to the surfaces by the resin film that forms as the foam begins to dry. This effectively prevents it swirling up due to subsequent air currents and impact sounds from footsteps, etc.
Mould infestation with spore release.
Biocidal active foam encapsulates and inactivates moulds. Dead mould components are encapsulated and fixed in place.
The classic and always recommended method for mould removal (the HEPA Sandwich Method), where you:
1. First, thorough HEPA vacuuming of the affected surfaces for loose mould material.
2. Chemical cleaning or mechanical processing of the surface or a combination of these two methods.
3. Finally, VERY careful HEPA vacuuming of remaining inactivated mould material.
However, the HEPA Sandwich Method cannot always be used for technical and economic reasons. Eg. for hard-to-reach surfaces, cavities, etc.
The reasons can be:
1. Cavities under floors which rest on joists/beams or are otherwise raised.
2. Cavities in intermediate walls.
3. Hard-to-reach places due to mould in crawlspaces and attics etc.
In such cases, and in all other hard-to-reach places with limited space, a treatment with biocide-containing active foam can be a good alternative. This is because the mould material is treated/inactivated with the biocide product Sanosil SD7, and is encapsulated and fixed (sealed) on the surfaces by a breathable modified acrylic resin film which forms during drying. This means that mould material can no longer be released into the air. Prior to such treatment, it is of course assumed that the cause of the mould growth has been resolved.
Cross-sectional model of a cavity after water damage with severe mould.
Sanosil SFS mixed with Sanosil SD7 is foamed using a Birchmeier Indu-Matic 20M foam sprayer and fed into the cavity.
The foam collapses and forms a sealing film. The remaining moisture must then be dried out.
The combination of SD7 with Sanosil SFS is ideal for controlling mould in cavities that are difficult to access. SFS is an additive that significantly increases the foamability of SD7 and makes a firmer, more stable foam possible. This can be pressed into mould-infested cavities and crevices, allowing disinfection there too. The dead biomass is fixed to the surface as the foam dries.
Identify and eliminate the cause of mould (e.g. leaking drainpipe). Otherwise, mould may start to grow again after a while.
Mix 1 part Sanosil SFS with 3 parts Sanosil SD7 and pour the solution into a foaming device. For the best results, a professional foaming device with a compres-sed air connection or an additional compressor with 6 bar/150 l of air output/min is required. Our recommendation: Birchmeier Indu-Matic 20M. This device produces a stable, fine creamy foam.
50 ml of SFS combined with 150 ml of Sanosil SD7 forms 200 ml of foam concentrate, which can be foamed to 25 to 50 times the volume (5,000 –10,000 ml). Cavities can thus be completely filled with disinfectant foam through holes (which may need to be drilled first). If necessary, a flexible PVC hose can be attached to the lance nozzle (using a suitable clamp), which can be moved in the cavity and simplifies foam distribution.
After the foam has been applied, wait for the foam to break down and for the film to form after drying. The exposure time depends on the situation, but should be several hours, or preferably overnight. Any remaining moisture can then be removed by blowing in warm drying air.
Any openings made to the foamed cavities for inserting the foam should not be closed again until it has been ensured that all residual moisture has dried out and the cause attributed to the mould growth has been completely eliminated.
Important: Always wear protective equipment (eyes and skin protection, P3 dust mask) during mould remediation work and when handling Sanosil SD7. Avoid skin and eye contact with SD7 or mould components.
Identify and eliminate the cause of mould (e.g. uninsulated roof substructure with moist air rising from the living area). Otherwise, mould may start to grow again after a while.
Mix 1 part Sanosil SFS with 2-3 parts Sanosil SD7 and pour the solution into a foaming device. For the best results, a professional foaming device with a compressed air connection or an additional compressor with 6 bar/150 l of air output/min is required. Our recommendation: Birchmeier Indu-Matic 20M. This device produces a stable, fine creamy foam.
Mix 40–50 ml of Sanosil SFS and 100 ml of Sanosil SD07 per m2 of surface and fill it into the foaming device. Wear protective equipment (for the skin/eyes). Connect the compressed air hose, select a relatively light foam setting and foam at 3.5 – 4 bar pressure using the flat spray nozzle. Wear suitable respiratory protection (min. P3) to protect yourself from aerosol formation. Foaming a surface with an area of 1 m2 takes approximately 20 seconds.
After the foam has been applied, wait for the foam to break down and for the film to form after drying. In case of enclosed rooms with poor air circulation, install a drying device to support the drying process as necessary.
1. Use safety glasses. Eye protection must comply with EN 166.
2. Use plastic or rubber gloves.
3. Use protective suit type 5-6. When spraying above head height with a risk of splashing/drip, use chemical suit type 3-4.
4. Respiratory protection. A full face mask with a B2/P2 filter must be used for fog spraying.
