Sanosil SD7
User guide for mould remediation. Cleaning in indoor environments of mould, bacteria etc.
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 odourless.
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 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.
IDEAL FOR EFFECTIVE CLEANING AND DISINFECTION OF ALL TYPES OF MOULD ATTACKS

WHERE CAN I USE SANOSIL SD7?
Material / Surface
Wallpapered surfaces with loose/slight mould growth on the upper side.
Wallpapered surfaces with mould growth on the back of the wallpaper and/or on the substrate.
Glass fabric/glass felt with a painted surface mould growth on the surface.
Glass fabric/glass felt with a painted surface with mould growth on the back of the fabric/felt and/or on the substrate.
Other painted / varnished surfaces with mould growth on the surface.
Plaster layer with mould growth on the surface.
Plaster layer with mould growth in depth.
Concrete walls without wallpaper, glass fabric and the like.
Concrete floors without flooring and glue.
Aerated concrete – interior.
Masonry – interior.
Roof tiles – the underside of underlined roof tiles.
Boards – roof structures.
Plywood – roof structures.
Solid wood – structural beams/rafters.
Solid wood – constructions in glulam/CLT.
Solid wood – floorboards.
OSB, MDF, plywood where the materials are not used in roof constructions.
Plasterboards
NOTE!
The wallpaper must have a good structure and sit firmly on the wall. If not, remove the wallpaper and apply SD7 on the substrate.
Remove wallpaper and apply SD7 to the substrate.
Remove the 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.
RESERVATIONS
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 deemed that the mould attack is deeper, a cleaning with Sanosil SD7 can be combined as necessary with a Serum 1000 cleaning or mechanical cleaning such as e.g. planing, grinding/milling or media/sandblasting, etc.
USER INSTRUCTIONS
PREPARATION OF THE WORKPLACE
COVERAGE:
1 liter 15-20 m2 on light mould attacks.
1 liter 4-8 m2 on moderate-severe mould attacks.
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.
PROCEDURE FOR TREATMENT WITH SANOSIL SD7
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 syringes. 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. Check the cleanliness of the surface with the 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.

PERSONAL PROTECTION:
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 when fog spraying.
NAC

The NAC Power Sprayer series consists of a number of professional electric sprayers, which deliver extremely good operational reliability and constant pressure with perfect and uniform spray patterns – the electric sprayers are made for the disaster restoration service industry.
NAC Power Sprayers will never let you down, regardless of whether you use them to apply disinfectants, mould remediation, odour remediation or cleaning agents, etc. At NAC Europe, we know that it is motivating to work with tools that make the work process simple, fast and efficient, thereby creating the best and most profitable results. Because as they say:
GOOD TOOLS ARE HALF THE JOB!
If a final disinfection of the entire mould-remedied area is desired, we recommend 3D room disinfection with Sanosil S010 or S015 in the disinfection machines Q-Jet 10 or Q-Jet 20.
