THE BEST OF BOTH WORLDS
The protection and breathability your home need
You no longer have to choose between breathability and weather protection – with nano-technology you and your home can enjoy the best of both worlds.
The problem with standard paints
When choosing a paint for the outside of your home you want one that will prevent water entering your home, but also allow moisture that is present within the wall to naturally escape, keeping your home dry.
The reality is however, the majority of standard masonry paints in the UK do not provide both.
- Standard masonry paint (acrylic-based) – not highly water resistant and not highly breathable
- Oil-based masonry paint – high water resistance but very low breathability
- Limewash – low water resistance but highly breathable

Introducing nano-technology
Water vapour molecules are incredibly small at around 0.0000001 mm (one ten-millionth of a millimetre). Raindrops, by contrast typically range from 0.5 to 4 mm in diameter and can be as large as 6 mm during heavy rainfall (Royal Meteorological Society).
This means raindrops are between 1.8 million and 21 million times larger than water vapour molecules.
This difference in size is how nano-technology can ensure rainwater cannot pass through the surface, while water vapour crucially can.
How nano-technology works
1. Repels Water
At a microscopic level, our formulation is comprised of millions of pyramids that are invisible to the naked eye. When a bead of water hits these pyramids it cannot attach to the surface, causing it to simply roll away. Imagine trying to balance a ball on the tip of a pyramid – the ball rolls off instantly. That’s exactly what happens when a bead of rainwater hits our nano-technology.
2. Does not block pores
Within this web of pyramids is an open-pore structure. When these pores align with the natural pores that are present on the exterior walls of your home, the essential pathways for water vapour to naturally pass through the substrate are preserved.
