PU Coating Waterproofing Solution
PU coating is a liquid-applied waterproofing system that creates a seamless and flexible protective layer over the treated surface.
Once cured, the coating bonds strongly to concrete, metal, tiles and roofing surfaces. This creates a durable waterproofing barrier that helps protect exposed areas against Malaysia’s heavy rainfall, intense heat and humid weather conditions.
Its flexible properties also allow the coating to accommodate minor surface movement, making PU coating suitable for balconies, roofs, slab roofs, planter boxes and other exposed areas.
What is PU Coating
PU coating, also known as polyurethane coating, is a liquid waterproofing system that forms a continuous protective membrane once cured.
Our team applies the coating directly onto a properly prepared surface. Because the material starts in liquid form, it can cover corners, joints, uneven surfaces and other difficult areas without creating seams between sheets.
Once cured, the coating forms a flexible waterproof barrier that helps protect the underlying surface from water ingress and weather exposure.
PU coating can also accommodate minor structural movement and bridge small surface cracks. Therefore, it is particularly suitable for exposed areas that experience changes in temperature, sunlight and rainfall.
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
First, our team cleans and dries the surface to remove dust, dirt, grease and loose materials. We then inspect the area for cracks, holes or damaged sections that may affect the waterproofing system. Where necessary, we repair these defects before applying the coating. -
Second Layer: Apply the Coating
Next, we apply the PU coating evenly across the prepared surface using the appropriate application method. Our team pays particular attention to edges, corners, joints and penetrations to ensure consistent coverage across critical areas.
The liquid coating then begins forming a seamless waterproofing layer as it cures. -
Third Layer: Repeat for Full Coverage
Once the first coat has dried sufficiently, we inspect the surface before applying the next layer. We then apply another coat across the treated area to build up the waterproofing system and achieve more consistent coverage. Where required, we apply the next coat in a different direction to help achieve an even and continuous protective layer.
Finally, our team checks the completed surface to ensure proper coverage before handover.
