PU Coating Waterproofing Solution
PU coating is a liquid waterproof layer that dries into a strong, flexible “protective skin” over your surface. It sticks well to concrete, metal, tiles, and roofs, and has no joints where water can sneak in.
It can handle Malaysia’s hot sun, heavy rain, and small cracks without breaking. When applied properly, it helps stop leaks, protects the surface, and lasts for many years with minimal maintenance.
What is PU Coating
PU Coating (also known as Polyurethane Coating) is a high-performance, liquid-applied waterproofing system designed to create a seamless and fully bonded protective membrane over exposed surfaces. Applied as a liquid, the coating cures into an elastic, durable film that adheres strongly to concrete, screed, metal, tiles, and various roofing substrates, forming a continuous waterproof layer with no joints or weak points.
Our PU coatings are made from premium-grade polyurethane with excellent flexibility, tensile strength, and UV resistance. This advanced formulation allows the coating to accommodate structural movement, bridge hairline cracks, and withstand long-term exposure to heat, sunlight, and ponding water. Its ability to expand and contract without breaking makes it especially suitable for Malaysia’s hot and humid climate.
PU coating provides a robust barrier against water ingress, weathering, and surface deterioration. When paired with expert surface preparation and precise application, PU coating delivers a long-lasting waterproofing solution that enhances the lifespan of exterior surfaces while reducing maintenance needs.
Key Benefits of PU Coating
Our PU coating system provides excellent flexibility, UV resistance, and strong adhesion, forming a seamless waterproof layer that stands up to heat, weathering, and surface movement. It is ideal for both commercial and residential projects that require reliable, low-maintenance protection for exposed areas.
Efficiency
PU coating offers a fast and efficient installation process, reducing downtime and allowing waterproofing works to be completed with minimal disruption, ideal for both commercial and residential properties.
Resistant
Highly flexible and UV-stable, the coating withstands thermal movement, direct sunlight, and ponding water, maintaining consistent waterproofing performance over time.
Versatility
Adapts well to complex details, uneven surfaces, & roof penetrations. Its liquid-applied system, it provides seamless coverage even around difficult areas.
PU Coating Application Method
Let’s take a step-by-step deep dive into how a PU Injection waterproofing system is applied, breaking down each stage from surface preparation to the final injection process, with clear steps, technical details, and practical considerations.
-
First Layer: Prepare the surface
Clean, dry, and lightly sand the area to remove dust, dirt, grease, and loose material. Repair any major cracks or holes first -
Second Layer: Apply the Coating
Choose a brush, roller, or spray, and spread thin, even coats, making sure edges and corners are fully covered. -
Third Layer: Repeat for Full Coverage
Allow the first coat to dry, lightly sand if needed, then apply a second coat perpendicular to the first for complete protection.
