Introducing our MR Mould Mould Killer - a powerful 50ml solution designed to tackle mould growth head-on. Say goodbye to unsightly mould and hello to a cleaner, healthier environment.

Our Mould Killer is not your average anti-mould treatment; it's a professional-grade additive specifically formulated to stop mould growth in its tracks. With its fast-acting formula, it provides rapid relief against growing mould, ensuring a preventative treatment that safeguards your surfaces from the effects of condensation-related issues.

Formulated with a potent fungicidal composition, Mould Killer offers a unique solution by seamlessly integrating into any colour paint, tile adhesives, grout, or wallpaper paste. This versatility means you can protect a wide range of surfaces throughout your home or workspace with ease.

Before application, it's essential to prepare the surface properly. A thorough wash with a 50:50 bleach and water solution removes existing mould, allowing Mould Killer to work effectively. Once dry, simply mix 10ml of Mould Killer per 1L of your chosen medium, ensuring thorough incorporation.

As with any potent solution, it's crucial to handle Mould Killer with care. Precautionary measures include avoiding contact with eyes and ensuring proper ventilation during application. In case of accidental contact with eyes, rinse immediately and seek medical advice. Keep the product away from treated surfaces until dry, and wash hands and exposed skin after use. Additionally, ensure the product is stored safely out of reach of children and seek medical advice if ingested.

With its powerful formulation and easy application, our Mould Killer offers a reliable solution to combat mould growth effectively. Say hello to a mould-free environment and enjoy cleaner, healthier surroundings today.

    How to prepare your surface? 🏡


    Mould Killer and Paint Additive: 🏡

    Reading the following  information  below will help you understand  how to prepare all surfaces to be painted like a pro.

    Whether you’re painting your Interior, Exterior or furniture. The surface preparation remains the same.

    To get the best adhesion & results from HQC mould additive in your Paint, you need to get your surface ready in 3 Short Steps.

    It's critical to achieve perfect results.

    Preparing your surface correctly before using MR MOULD - Mould Killer and Paint Additive is essential for effective mould treatment and prevention. This guide is tailored for areas prone to mould, such as bathrooms, kitchens, and damp walls.

    Step 1):

    Identify and assess the mould-affected areas. Ensure they are dry and clean. For extensive mould growth, especially on exterior surfaces, a jet wash might be necessary to remove stubborn mould and debris. For interior areas, clean the surface thoroughly with a suitable cleaner to remove all mould traces. If you're working on previously painted surfaces, remove any peeling or flaking paint and sand down rough patches.

    Step 2):

    Ensure that the cleaned surfaces are completely dry. Address any moisture sources that may have contributed to the mould problem, such as leaks or poor ventilation. Repair any cracks or damages in the surface, as these can harbour moisture and lead to mould recurrence.

    (If your painting on fresh plaster please apply a base-coat or a primer before painting, thinning this paint with 50% water will allow a thin layer to be used as a base/mist coat) (use primer on wood & metal surfaces.)

    Step 3):

    Check the surface for any remaining dust, debris, or moisture. The area must be completely dry and free from any contaminants before applying any treatment or paint. This ensures that when you apply MR MOULD - Mould Killer and Paint Additive , it adheres properly and functions effectively. A clean, dry surface is crucial for the effective application of products mixed with MR MOULD - Mould Killer and Paint Additive. This step is vital for the additive to function properly, whether it's mixed into paint, grout, or any other applicable medium.

    (NOTE: Solving underlying moisture issues and ensuring good ventilation are critical to preventing mould regrowth. MR MOULD - Mould Killer and Paint Additive will treat and protect the surface, but addressing environmental factors is key for long-term effectiveness.)
