Floor Coating

ECO-TANSUNGTAN VERY HARD

usage
Athletics track, parking lots concrete surfaces requiring elasticity

ECO-TANSUNGTAN VERY HARD is heavy-metal free and meets KS F 3888-2 standards. It is a solvent-free elastic urethane intermediate coat which has excellent adhesion, wear resistance and shock resistance. High build films can be obtained in a single coat. It has good leveling and elasticity thus it is suitable for athletics track, parking lots.

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 oil, moisture, sand, dust, laitance and foreign substances 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.
2. Apply smoothly on the undercoated surface using sawtooth scraper, rubber scraper, pitchfork, roller, etc.

Appropriate construction specifications
▷Primer : CLEANTHANE 1000
▷Intermediate coating : ECO-TANSUNGTAN VERY HARD
▷Top coat : TANSUNGTAN TOP COAT (HARD, VERY HARD) DHDC-3000(H)
Coating conditions
1. Atmosphere Temperature: 5~35℃, Surface Temperature: 40℃ or below, Relative Humidity: 80% or less moisture content in the concrete: 6% or less
2. 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. `
3. Scrape (or front-putty) the concrete surface to a thickness of about 0.5 to 1.0mm to minimize the occurrence of pinholes and bubbles due to pores there. For intermediate coat, apply the scrapping in the first place and then the main coating in two separate runs.
4. It is not suitable for places that receive large loads such as forklifts and medium/large trucks.
