Mouldguard is a ready-to-use, high-performance fungicidal cleaner for wood, that removes mould, mildew, algae, and bacteria while sterilising surfaces to prevent regrowth. Its thixotropic, water-based formula works on both vertical and horizontal surfaces, making it ideal for preparing timber before coating. Free from hazardous solvents and alkalis, it’s safe for use on hard and soft wood, without causing efflorescence. It also penetrates the timber to continue to protect from mould and mildew over time.
