The superior technology mimics the ‘lotus-leaf’, repelling dirt and water to give a super hydrophobic effect, making walls/roof tiles self-cleaning.


  • Dirt particles are unable to obtain a hold on ProPERLA treated surfaces and will simply flow off with rainfall.

  • Helps to prevent discolouration and salt efflorescence.

  • Makes it difficult for the growth of moss, algae or lichens.

  • Slows the ageing or breakdown of the surface of the building or its tiles.


The masonry and tiles remain clean and attractive, even areas that are exposed to extreme weather conditions including shade, high air humidity or sea salt penetrated air. ProPERLA Water Repellent is entirely unaffected by UV rays.



A surface is superhydrophobic if a water droplet beads up with a contact angle greater than 150 and the droplets can slide aware from the surface readily. Super-hydrophobic surfaces repel water, causing it to form beads because it is more attracted to itself than the surface. That 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.

Mineral surfaces like roof tiles which have been coated with ProPERLA Water Repellent will respond in the same way – water will form droplets and won’t penetrate the substrate.



ProPERLA Water Repellent is weather-resistant in accordance with VOB – meaning the products can withstand all climatic conditions

ProPERLA Water Repellent is manufactured in accordance with DIN 4108 – European rating for water repellency

ProPERLA Water Repellent has been tested and certified in accordance with EN1504-2: 2005, confirming the depth of penetration, water absorption, resistance to alkali, drying rate and thermal conductivity.
