CoolTop is a white, reflective, two-component coating designed for application to building roofs. Rooftops typically feature dark-coloured materials that absorb a lot of heat, which increases the temperature of the entire building structure. 

CoolTop white reflects the solar radiation it receives and creates a thermal barrier, so the building accumulates very little heat

Application of a Green Roof

• Check the substrate is clean and in good condition.
• Application temperature must be between 5 – 35ºC.
• All trims must be fixed prior to Ultraflex application.
• Use Ultraflex sealant to seal any cracks or gaps.
• Open the drum and stir before applying Ultraflex.
• If product is left to stand on site, stir again before application.
• Apply Ultraflex liquid as described below, first to details and perimeters and then to the flat area.
• Apply Ultraflex liquid wet-on-wet by applying a generous coat of liquid first, then dry rolling the matting into the liquid and finally applying more liquid on top to achieve the required thickness. Ensure the matting is fully encapsulated without pinholes or tenting.
• At this stage the roof is watertight and will resist rain.
• Typical coverage is 8-10 sqm per drum although this may vary depending on substrate.
• After applying the waterproofing layer, check for pinholes or any dry areas that may require more liquid.
• Once the Ultraflex membrane is dry, apply a layer of Ultratop topcoat within 48 hours.
• Check the full application sheet for specific substrates and systems.
