Ronseal MKT500 3-in-1 Mould Killer Trigger Spray 500ml

Ronseal 3-in-1 Mould Killer Trigger Spray is a fast-acting mould solution designed to kill mould on contact, clean surfaces, and provide ongoing protection against regrowth. It’s suitable for bare or previously painted walls and ceilings, helping to remove mould stains and prevent future outbreaks. The product is low in VOC and available as a ready-to-use 500ml spray, with options for use on interior surfaces such as walls, ceilings, tiles and grout. It is designed for high‑moisture rooms like bathrooms and kitchens, where condensation or damp is common. The formula targets mould while cleaning and sanitising the area, leaving surfaces looking cleaner and brighter.

This mould killer is prepared for straightforward application without mixing. Shake the bottle well, perform a patch test on a small area to check compatibility, and break the tamper seal by squeezing the trigger. It is formulated to be used on mould-affected surfaces, including vertical areas, and is compatible with bare or previously painted surfaces.

The product combines cleaning, disinfection and anti-regrowth protection in one, making it suitable for treating stubborn mould patches and helping to maintain cleaner surfaces over time.
