Waterproof Coating for Complex Surfaces

Seamless waterproofing solutions designed for joints, penetrations, and irregular structures where traditional membranes cannot perform effectively.

Waterproofing Problems Always Start at the Details

In most waterproofing projects, failures rarely occur on large flat surfaces. The weak points are usually joints, corners, penetrations, and transitions between materials.

These areas are difficult to seal using sheet membranes because they require cutting, overlapping, and manual sealing, which increases the risk of leakage.

Waterproof coatings are designed to solve this problem by forming a seamless, continuous layer that fully adapts to complex shapes.

Why Complex Surfaces Need Coating Solutions

  • Pipe penetrations and roof details
  • Joints, corners, and transitions
  • Equipment bases and supports
  • Curved or irregular structures

In these areas, coatings provide full coverage without seams, significantly reducing leakage risk.

Key Advantages of Waterproof Coatings

Seamless waterproof layer (no joints)
High flexibility for movement and expansion
Strong adhesion to concrete, metal, and other surfaces
Easy application (brush / roller / spray)
Ideal for repair and detail sealing

Typical Applications

Roof penetrations and flashing details
Balconies and terraces
Bathrooms and wet areas
Industrial equipment bases
Repair and maintenance projects

Main Types of Waterproof Coatings

Polyurethane (PU) Coating

Best overall solution for complex waterproofing.

  • High elasticity and flexibility
  • Strong adhesion
  • Excellent durability

Acrylic Coating

Cost-effective and UV-resistant solution.

  • Good UV resistance
  • Easy application
  • Suitable for light-duty waterproofing

Silicone Coating

Best for high-moisture environments.

  • Excellent water resistance
  • High weather resistance

Cementitious Coating

Best for concrete-based structures.

  • Good compatibility with concrete
  • Easy application

Coating vs Membrane: Which Is Better?

Complex surfaces: Coatings are the preferred solution due to seamless coverage.

Large flat areas: Membrane systems are more efficient and cost-effective.

Flexibility: Coatings provide higher adaptability to movement.

Installation: Coatings are easier to apply on irregular structures.

How to Choose the Right Waterproof Coating

Surface type: Concrete → cementitious or PU; metal → PU or silicone.

UV exposure: Acrylic or silicone coatings are recommended.

Movement: Use highly elastic coatings such as PU.

Project type: Repair → PU or silicone; new construction → depends on system design.

Budget: Acrylic for cost control, PU or silicone for higher performance.

Application Process

  • Surface preparation (cleaning and repair)
  • Primer application
  • Coating application (multiple layers)
  • Curing and inspection

Proper surface preparation is critical to ensure adhesion and long-term performance.

Common Problems and Solutions

  • Poor adhesion: caused by dirty or wet surface → ensure proper preparation
  • Cracking: caused by low flexibility → use elastic coatings (PU)
  • Leakage: caused by insufficient thickness → apply multiple layers
