Enormous amounts of thermal energy are easily transferred through the roof , resulting in large amounts of energy being required to heat and cool the building. In addition, water seeps into the building from parts of the roofs where the insulating materials have failed, creating dampness and mold in the interior walls and ceilings. The bitumen waterproofing solution created enormous problems in the insulation of roofs: a) it collects the incident heat radiation and heats the buildings, b) the stains are obvious and the failure at the joints of the bitumen and parapets or between the bitumen rolls leads to the complete failure of said insulation system.

The same can be true of old polyurethane systems that turn yellow over time and crack due to water containing atmospheric contaminants. A system that can adhere to old polyurethane and tarps and repair cracked, yellowed surfaces that are difficult to achieve is the NanoPhos system.

• Surfa Pore® FX | for waterproofing and stabilization of loose cementitious substrates (if required)
• Surfa Mix® P or Universal Primer or Epoxy Primer WB | to prepare the application surface (depending on the existing substrate)
• Surfa Paint® Elastomeric Hellas Cool White or Elastomeric Roof Hybrid | final coating to waterproof the surface
• Surfa Shield® C | for the self-cleaning of the final surface through photocatalysis ( optional )

Application Tips:

1. New cement substrates should be cured for more than 3-4 weeks before applying the primer. Make sure the roof is dry and free of mold, dirt, dust, oily residue or materials from previous applications.
2. Apply Surfa Pore® FX by brush, roller or simple sprayer and let it dry for a day. SurfaPore FX WB should only be applied to cementitious substrates.
3. Apply one of the Surfa Mix® products as a primer , depending on the existing substrate. For more technical clarifications, you can contact the Technical Department of NanoPhos.
4. Apply Surfa Paint® Elastomeric Hellas Cool White or Elastomeric Roof Hybrid, two coats, crosswise using a sprayer or roller. Make sure the edges and corners are completely covered. The application surface should be covered crosswise (horizontally and vertically) to ensure even application. Additional coats should be applied 24 hours after the previous application.
5. Following the application of the sealant, it is recommended to optionally apply Surfa Shield® C using a simple sprayer. Maximum effectiveness is achieved 24 hours after application.
