Waterproof Coating

CLEANTHANE 2100 PLUS Elastic urethane intermediate coating for waterproofing

Waterproofing material for various engineering works, rooftops of buildings and other areas

This paint is a room-temperature curing 2K polyurethane intermediate coating suitable for rooftop waterproofing due to its excellent tensile strength, tearing strength and elongation. Due to its self-smoothing ability, it can form a seamless film and is excellent in water resistance, chemical resistance and durability. It can also form a uniform coating film. Moreover, it is a high-grade exposed type elastic urethane intermediate material that is easy to repair even if the waterproof layer is broken.

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 : CLEANTHANE 2100 PLUS
▷Top coat : CLEANTHANE 3000K
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.
