A surface is considered super hydrophobic if a water droplet beads up (with a contact angle greater than 140⁰ and the droplets can slide aware from the surface readily (it has a small contact angle hysteresis). Super hydrophobic surfaces repel water, causing it to form beads because it is more attracted to itself than the surface. This means water will run off the surface making it extremely difficult to wet.
This is known as the ‘lotus effect’ due to its similarity to the lotus leaf but is also seen on duck feathers and butterfly wings.
Roofs coated with RENOTEC will respond in the same way – water will form droplets and won’t penetrate the tiles. Independent testing has shown that it reduces water absorption by 96.3% and meets the British standard for water vapour resistance BS EN ISO 7783:2011.
RENOTEC does not restrict the ability of the building to breathe. Water vapour permeability testing was conducted in accordance with BS EN ISO 7783:2011 and it demonstrated that the coating had little effect on the water vapour diffusion of the tiles.
Application of RENOTEC roof coatings protects a roofs tiless by keeping them dry whilst allowing air and moisture to escape. It maintains the important capability of a building to breathe.
