Key Features & Benefits

• 25 pre-measured sachets: Makes up to 8 litres of black mould solution, with an accurate dose every time and no measuring on site.

• Scales with your service: Use with the Starter Pack spray bottle for spot treatments, or with a mister or fogger for larger areas.

• Simple, repeatable method: Spray, leave for 15 to 30 minutes, wipe and re-spray. Clear steps make the treatment easy to train, deliver and document.

• No pre-cleaning required: Apply directly to the mould without dry-brushing or pre-cleaning, which removes a step from every treatment.

• Built-in follow-up visits: The preventative protocol calls for a light spray every two weeks until the moisture problem is fixed, creating scope for scheduled return visits.

• Compact sachet format: Sachets are easy to carry on vehicles and keep for 4 years when sealed.

• Odourless powder: The powder has no odour.

How to Use

1. Dissolve three 6g sachets (18g) in 1 litre of water in a spray bottle or mister. Do not use the powder neat.
2. Do not dry-brush or pre-clean the mould.
3. Lightly mist the affected area until wet.
4. Leave for 15 to 30 minutes.
5. Wipe the treated area, then apply a light second spray.
6. For heavy contamination, carry out a second full treatment.
7. As a preventative treatment, apply a light spray every two weeks until the moisture problem is fixed.

Ventilate the room during and after treatment. When fogging or misting a whole room, keep other people and pets out until the mist has settled. Do not use on people, animals or food, and do not mix with other chemicals, disinfectants or cleaning products.

Personal protective equipment: Wear chemical-resistant gloves at all times and safety glasses or goggles when spraying. Wear an FFP3 mask or P3 respirator when misting or fogging, or when treating heavy mould in confined spaces. See Section 8 of the safety data sheet.

Why Pest Controllers Choose This Product

The Refill Pack keeps a mould treatment service running. Pre-measured sachets keep dosing consistent across technicians, and the choice of spray, mister or fogger lets one product cover jobs of different sizes.

Pest control businesses already work in homes and commercial premises where damp and mould can occur. In England, social landlords also have duties to address damp and mould under Awaab's Law, which came into force in October 2025. SANI-99™ Black Mould lets pest control businesses respond to that demand with a simple, documented treatment method.
