Waterproof Coating

ENERGY SAVER Urethane(R) intermediate coating

Waterproof intermediate coating exclusive for rooftops and exposed areas (energy-saving type)

This paint is an energy-saving urethane intermediate coating for rooftop waterproofing, to which new functions that were not available in the past have been imparted. It has a high reflectance and a low thermal conductivity, so it can reduce the cooling/heating energy of a building. It is made of an urethane material and is excellent in physical performance in terms of elongation, adhesion and elasticity. It can form a seamless film, so a uniform film layer can be formed.

how to use

Surface treatment
1. Cure concrete for at least 28 days at a temperature of 21℃ and a relative humidity of 50%.
2. Completely remove the oil, moisture, sand, dust, laitance and other foreign matter from the surface and maintain surface smoothness.
3. For high-strength concrete (260㎏/㎠ or higher), blasting treatment should be carried out.
Coating method
1. Reinforce cracks, crevices, and joints between walls and floors with the NEW-THANSUNG SEAL(N).
2. Apply smoothly on the undercoated surface using sawtooth scraper, rubber scraper, pitchfork, roller, etc.
Appropriate construction specifications
▷Primer : CLEANTHANE 1000
▷Intermediate coating : ENERGY SAVER Urethane(R) intermediate coating
▷Top coat : ENERGY SAVER Urethane(R) top coat
Coating conditions
1. Atmosphere Temperature: 5~35℃, Surface Temperature: 40℃ or below, Relative Humidity: 80% or less.
2. Moisture content in the concrete: 6% or less.
During scorching heat in the summer (atmospheric temperature: 28℃ or higher; surface temperature: 40℃ or higher), please apply after 4 pm when the surface temperature drops.
