A surface is considered super hydrophobic if a water droplet beads up (with a contact angle greater than 150°). 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.

Mineral surfaces like roof tiles that are coated with ProPERLA Water Repellent respond in the same way, resulting in water forming droplets and running off the substrate without penetrating the surface.

Product Guarantee


ProPERLA Water Repellent comes with a 10 year manufacturer’s guarantee.

This means there is no need to re-apply every few years, which can be the case with roof sealing paint.

Breathable

There is no restriction on the ability of the building or roof of the property to allow air and moisture to escape and breathe out. ProPERLA Water Repellent benefits from an SD (breathability rating) of 0.03. A coating is considered to be breathable if it has an SD value of 0.50.

A breathing roof will improve its insulation properties. Just a 5% content of damp in building materials can lower the thermal resistance by up to 50%.

Keep The Property Clean & Attractive

The superior technology of the clear roof treatment mimics the lotus leaf, repelling dirt and water to give a super hydrophobic effect, making roof tiles self-cleaning.

The tiles remain clean and attractive, even where they are exposed to extreme weather conditions including shade, high air humidity or sea salt penetrated air.

Furthermore, ProPERLA Water Repellent is completely unaffected by UV rays.
