Long-term mould control – thanks to a natural organic formulation
Formulated from natural organic products, including grapefruit extracts, and free from biocide chemicals, the additive acts as an anti-fungal control when dispersed through water-based paint. Regular application to condensation-prone surfaces reduces the likelihood of black grime returning.
Effective prevention reduces repeat redecorating and cleaning, giving a lasting improvement on affected walls and ceilings. Trusted by both amateurs and professionals for sustained results.
Easy mixing with invisible finish – with a concentrated, colour-stable formula
A measured dose of 100ml per 5 litres of standard emulsion must be mixed thoroughly until the colour is even, as instructed by paint manufacturers. User feedback confirms the additive does not alter paint colour or finish when blended correctly.
Keeps the original paint appearance while delivering anti-mould protection, so redecorating looks professional without additional touch-ups. Small bottles treat multiple litres, reducing trips to the shop.
Versatile application – with compatibility across common water-based materials
Safe to add to water-based emulsion paint, wallpaper paste, PVA, tile adhesive and tile grout, but explicitly unsuitable for oil-based paints. Adequate ventilation and appropriate personal protective equipment are advised during use.
Useful for a range of interior repair and renovation tasks, from repainting a bathroom to regrouting tiles, making it a handy product to keep for damp-prone rooms.
