PU Aqua Shield (Shield 402) is a high-performance lamination exterior waterproof paint formulated with advanced PU technology and pure acrylic latex, enhanced by core-shell modified silicone. Designed to withstand severe climatic conditions, it provides long-lasting waterproofing, structural protection, and an attractive glossy finish.

This premium waterproof coating offers high elongation (80–100%), excellent crack-bridging capability up to 1.5 mm, and superior resistance to water seepage. Its anti-carbonation and CO₂ diffusion resistance properties help prevent corrosion of reinforcing steel within concrete, ensuring long-term durability of structures.

PU Aqua Shield remains fresh and vibrant year after year due to its Shine Stay Technology, superior anti-fading performance, and strong resistance to algae and fungal growth. The coating is low VOC, environmentally friendly, and low-odor, making it ideal for both residential and commercial applications.

When applied with Concrete Gum Shield (Shield 302) or Shield Base Coat (Shield 303), PU Aqua Shield offers up to 10 years waterproofing and performance warranty.
