Waterproof Coating

BLACKTHANE AP

usage
Non-exposed waterproofing for concrete structures and general buildings

BLACKTHANE AP is a one-component asphalt–urethane waterproofing coating with excellent mechanical properties such as tensile strength, elongation, and tear resistance.
This product can be applied directly without mixing a base and hardener, providing superior workability.
It offers outstanding adhesion to substrates and excellent elastic performance, and it complies with KS F 3211 (Urethane Rubber Type, Class 2) for membrane waterproofing systems.

how to use

Surface treatment
1. Cure concrete for at least 28 days at 21℃ and 50% relative humidity.
2. Completely remove oil, moisture, sand, dust, laitance, and other contaminants and ensure surface smoothness.
3. For high-strength concrete (≥ 260kg/cm²), blasting treatment is required.
Coating method
1. Reinforce cracks, joints, and intersections between walls and floors using New Elastic Seal (KS F 4910).
2. Apply BLACKTHANE AP uniformly using a notched trowel, rubber trowel, or rake to ensure proper spreading of the waterproofing membrane. Install SKIN SHEET AP‑2000DS(V) simultaneously while applying the coating.
