Fungicidal Cleaners for Mould, Algae, Lichen & Moss
Fungicidal cleaners are formulated to tackle the persistent problem of biological growth on a wide range of surfaces. They are vital for eliminating mould, algae, lichen, and mildew, particularly in areas prone to dampness or minimal sunlight. These cleaners are designed to penetrate deeply into porous materials, breaking down spores and preventing their recurrence. This makes them a critical part of surface preparation for both decorative and protective coatings.
Typical applications include cleaning façades, patios, driveways, roofs, interior walls, and other surfaces exposed to moisture. In addition to removing visible contamination, fungicidal cleaners help ensure that subsequent coatings adhere properly and last longer. By preventing the regrowth of fungi and algae, these products maintain the cleanliness and safety of public and private spaces.
Fungicidal cleaners are available in a variety of formulations to suit specific needs. For sensitive environments, biodegradable and solvent-free options are ideal, offering effective cleaning without harming the ecosystem. Concentrated solutions are available for large surface areas, providing cost-effective cleaning power. They are typically applied using low-pressure sprayers, brushes, or rollers, and many products do not require rinsing, allowing for quick and efficient surface preparation.
These products are indispensable for interior painting, restoration projects, and new builds. Whether removing green staining from render or eliminating black mould from bathroom walls, fungicidal cleaners ensure that surfaces are thoroughly prepared for coating, sealing, or painting. Their use not only improves the aesthetic appeal but also promotes longevity and durability of treated surfaces.
