Why choose Graphenstone anti-mould paint?

Graphenstone anti-mould paints are naturally resistant to mould and mildew, primarily attributed to their high pH level of 12 and natural vapour openness. This high pH level creates a hostile environment for mould and mildew growth, as they thrive in acidic environments.

These features contribute to an inhospitable environment for mould and mildew growth in the following ways:

High pH (Alkalinity)

The elevated pH level of 12 in Graphenstone lime paints creates an alkaline environment on painted surfaces. Mould and mildew thrive in acidic conditions, and by maintaining a high pH, the paint inhibits the growth of these microorganisms. The alkaline nature of the paint creates an environment that is unfavourable for the development and sustenance of mould and mildew, acting as a preventive measure against their colonisation.

Natural Vapour Openness

Graphenstone anti-mould paints are created with natural vapour permeability, enabling the surface painted to have ventilation. This permits water vapour to move through the paint coating, lowering the chances of condensation forming on the underlying material. Condensation can lead to a wet atmosphere that is ideal for the growth of mould and mildew. By supporting breathability, Graphenstone paints aid in stopping the build-up of moisture in walls, reducing the favourable conditions for mould and mildew.

Moisture Regulation

The combination of high pH and vapour openness also aids in moisture regulation. By allowing the controlled passage of water vapour, our anti-mould paint helps regulate humidity levels on the painted surface. This controlled moisture environment further deters the formation and proliferation of mould and mildew. 

Anti-Mould Paint - Summary

Graphenstone paints use their elevated pH level and innate vapour permeability to establish a space that is both alkaline and breathable. This two-fold effect serves as a shield against mould and mildew, enhancing the durability of the painted surfaces against their development.  In addition, Graphenstone paints are also eco-friendly and free from harmful chemicals, making them safe for both the environment and the people using them. This makes them an ideal choice for those looking for sustainable and non-toxic painting options.
