Key features
- No need for special handling or mixing on-site
- Free from harmful acids, salts, bleach, or abrasives
Tools for masonry cleaning:
- Use with powder, latex and silicone-free gloves
- Use a small nail brush or a smaller niche brush
- Use a polypropylene scraper for removing larger growths.
Application
Use on a variety of surfaces such as render, concrete, brick, cast stone, aluminium, vinyl, canvas, and wood. Always assess your building’s material and environmental conditions before cleaning. When applying D/2 with a 2-litre pressure sprayer, maintain a safe distance and spray lightly, avoiding excessive pressure to prevent damage.
Follow the Immediate Result Method:
- Spray D/2 directly onto the surface.
- Let it sit undisturbed for 10-15 minutes.
- Reapply as needed to keep the area wet.
- Use a large brush for extensive areas and a smaller brush for detailed spots.
- Lightly mist with water and scrub the surface.
- Rinse thoroughly with clean water.
- Reapply if rain occurs within 12 hours post-application.
A contact period of 10-15 minutes, combined with scrubbing, will help lift most biological stains. Observe that results may improve over 2-3 days as the solution interacts with the environment.
Always conduct a spot test before full application. For detailed product specifications, download the technical guide and datasheets.

- Allow the undiluted D/2 to sit on the surface for 10-15 minutes to ensure proper contact.
- Reapply D/2 as needed to maintain wetness on the surface during the process.
- Use a polypropylene scraper gently for larger biological debris to facilitate removal.
- For extensive areas, scrub with a nail brush, and use a smaller polypropylene niche brush for detailed cleaning.
