Maintaining the cleanliness and visual appeal of outdoor commercial spaces is crucial for creating a positive impression on clients and visitors.
However, one common challenge faced by contract cleaners and facility managers is the persistent growth of green algae and mould on concrete and stone surfaces. In this guide, we will explore the issues associated with green algae and mould on exterior surfaces, and provide a simple step-by-step approach to effectively eliminate them using Actichem mould exterminator.
Green Algae
Green algae thrive in both damp conditions and shaded areas, presenting the algae itself as a thin, green film on various surfaces. Commonly found on sidewalks, building exteriors concrete walls, and outdoor patio furniture, green algae not only pose visual concerns but also create slippery surfaces that can lead to safety hazards.
Mould
Mould, on the other hand, is a type of fungus that thrives in moist environments. It often appears as black or greenish patches on surfaces like walls, roofs, and outdoor equipment and plants. Besides compromising the visual appeal of the space, mould can pose serious health risks, especially for individuals with respiratory conditions.
Aside from compromising the visual appeal of the property, mould and green algae can lead to structural damage over time. Wet surfaces affected by green algae and mould become slimy and the surface can eventually turn black, making the property appear visually unappealing too.
The Power of Actichem Mould Exterminator
Actichem mould exterminator stands out as a specially formulated chlorine solution designed with an activator and super-wetting formula to target and eliminate green algae and mould at their roots. This powerful solution penetrates deep into affected porous surfaces, destroying mould hyphae and root systems for a long-lasting solution.
Cleaning solutions
Preparation
Before applying the Actichem mould exterminator, it is essential to ensure that the surface is dry and free of loose sand and debris. For optimal results, sweep, or blow down the surface and the entire area before application of Actichem mould exterminator.
Application
Use a pump sprayer or a brush to evenly apply Actichem mould exterminator to the affected areas. Complete coverage of small areas is crucial, with special attention given to corners and crevices where mould spores and algae tend to flourish.
Dwell Time
Allow the product to dwell on the surface for the recommended time, typically around 10-15 minutes. This dwell time is essential for the Actichem mould exterminator to penetrate the surface and break down the algae and mould effectively.
Agitation
For stubborn mould and algae growth and build-ups, gently scrub the surface with a brush after application of the Actichem mould exterminator to loosen organic growth and promote effective penetration of the chemistry.
Rinsing
Thoroughly rinse the treated area with clean water to remove the dissolved algae and mould residues. The use of a pressure washer can be a particularly effective method in achieving a deep clean and a rinse ensuring all the toxic black mould remnants are removed.
Repeat if necessary
In severe mould cases or for persistent mould growth, repeat the spray application process. Actichem mould exterminator is safe for repeated use, ensuring a thorough and lasting solution to mould growth.
Benefits of using Puregiene Mould Exterminator
Fast and effective
The powerful stain removal capabilities of Actichem mould exterminator can be observed almost instantly when applied to mould-affected surfaces. It provides outstanding cleaning power, eliminating organic grime without the need for other chemicals or extensive scrubbing.
Technology
Actichem mould exterminator incorporates unique activators, boosted with super wetting technology. This unique combination releases the full activity of Hypochlorous Acid making it dramatically more effective than chlorine bleach and traditional mould removal products. This innovative technology enables the Actichem mould exterminator solution to penetrate faster and deeper into the inner structure of mould and porous substrates to ensure a complete kill of mould spores and roots.
A long-lasting solution due to complete mould kill
The unique capabilities of Actichem mould exterminator mean that both the vegetative and spore form of mould and green algae is effectively eliminated. This significantly retards the regrowth of mould and green algae. Rapid regrowth is common with many mould removers due to them not effectively penetrating the surface pores and destroying the mould roots. The Actichem mould exterminator by contrast not only creates a clean, mould-free surface but by eliminating the mould roots and spores, its regrowth potential is dramatically inhibited.
Restore appearance
By removing mould by using Actichem mould exterminator, commercial spaces can restore the appearance of concrete floors, walls and stone surfaces, ensuring a clean and inviting environment for clients and visitors.
Health and safety
The elimination of mould and algae not only enhances the visual appeal but also contributes to a healthier and safer environment. Slips and falls associated with mould on paths and public spaces are a nightmare concern for many facility managers. Puregiene Mould Exterminator's thorough action helps mitigate health risks associated with algae growth and mould infestations.
Preventative measures for long-term results
While removing existing algae and mould is crucial, preventing their return is equally important for long-term success. Commercial cleaning businesses and contract facility managers should implement the following preventive measures to remove mould and algae further.
Regular maintenance schedule
Establishing a routine maintenance schedule is vital for preventing the reoccurrence of green algae and mould. Regular cleaning, especially in areas prone to dampness, in sunlight or shade, helps to prevent the problem before it becomes a more significant issue.
Proper drainage systems
Ensure that outdoor spaces have adequate drainage systems to prevent water ingress and dampness. Dampness provides an ideal breeding ground for algae and mould. Commercial cleaning businesses can advise facility managers on optimising drainage solutions to mitigate slow drying and mould-prone scenarios.
Adequate ventilation
Proper ventilation is key to getting rid of the moisture and preventing mould growth. Ensure that outdoor spaces have adequate airflow to minimise moisture retention. Addressing issues like poor ventilation in enclosed areas can significantly prevent moisture and reduce the likelihood of mould infestations.
Landscaping considerations
Strategic landscaping can play a role in preventing the growth of algae and mould. Trimming to get rid of overhanging trees, brush, grass and bushes allows more sunlight to reach surfaces, making them less prone to the development of mould and algae.
Educating clients on best practices
Commercial cleaning businesses and contract facility managers can provide added value by educating their clients on best practices for maintaining outdoor spaces and plants. Creating informational materials or conducting workshops to empower clients with the knowledge to contribute the best solution to the long-term cleanliness and safety of their commercial properties.
Maintaining outdoor commercial spaces free from green algae and mould is essential for creating a positive and professional impression.
