Built on deep technical insights into urea coating, spray foam, injection, and adhesive systems, we present the differentiated value of APTECH products and the reasons they are trusted and chosen across a wide range of industrial applications.
Why Spray Polyurea is Becoming the Standard in Waterproofing Systems
Technical Superiority, Low Defect Rate, and Life Cycle Cost Advantages of Spray Polyurea Over Conventional Waterproofing Materials
Why Spray Polyurea is Becoming the Standard
Spray Polyurea is currently established as a Standard Waterproofing System in various waterproofing applications such as bridges, parking structures, plants, and building structures.
This is because it has secured technical superiority over conventional liquid-applied waterproofing materials (Epoxy, 2K PU) in mechanical properties, application convenience, durability, defect rate, and long-term economic efficiency.
In addition, Spray Polyurea satisfies the requirements of extreme construction environments, and its applicability in functional performance fields continues to expand.
AP Tech Spray Polyurea System
AP Tech provides more than 20 years of experience in Spray Polyurea solutions ranging from Pure Polyurea to Hybrid systems, enabling optimized system application according to required field performance.
• UA-1001 — KS / KC Certification. Suitable for environments requiring both chemical resistance and physical strength.
• PK-410 — Mechanical properties similar to Pure Polyurea. Suitable for vehicle load resistance and anti-corrosion performance (e.g., parking structures).
• EPL-550 — Specialized for waterproofing applications. Field-proven top-selling product with excellent economic efficiency and extremely low defect rate.
AP Tech is designed to enable consistent Quality Control from substrate condition to finishing through an integrated system configuration: Primer → Intermediate Polyurethane → Spray Polyurea → Topcoat (UV protection).
Technical Superiority — Ultra-Fast Curing
• Gelation within 3–20 seconds → minimizes influence of moisture and rainfall
• Waterproofing and walkability immediately after application
• No damage during curing
Outstanding Mechanical Properties
• Elongation: 400–800%
• Tensile strength: 5–7 times higher than 2K PU
These properties enable long-term absorption of bridge vibration, repeated parking load, and micro-cracks.
Performance Under Moisture and Adverse Weather Conditions
• Applicable even on concrete where complete drying is difficult
• Stable reactivity in low and high temperature environments
A waterproofing system adaptable to various field conditions.
Defect Reduction Advantage
• Epoxy: insufficient elongation → failure to respond to cracking
• 2K PU: slow curing → bubbles, delamination, and process delay during curing
• Spray Polyurea: immediate performance after application → no curing-related defects
Defect rate reduction is a key driver toward standardization.
Long-Term Economic Efficiency (Life Cycle Cost)
Although initial material and equipment cost is higher than 2K PU, long-term economic efficiency can be secured:
• Reduced construction time
• Early reopening to service
• Extended maintenance cycle
Competitive advantage based on Life Cycle Cost (LCC).
Adaptation to Changes in Construction Environment
• Increase in short-term construction projects
• Increase in night construction
• Difficulty in long-term closure of bridges and large parking structures
These challenges are solved by ultra-fast curing Spray Polyurea.
Environmentally Friendly Waterproofing Material
• VOC Free (No Volatile Organic Compounds)
• Solvent-free System
• Eco-friendly material (HB Mark, Healthy Building Material)
FAQ
Frequently Asked Questions
It has secured technical superiority over conventional Epoxy and 2K PU in ultra-fast curing, high elongation, high tensile strength, low defect rate, long-term economic efficiency, and applicability in extreme construction environments.
With multiple performance-level products such as UA-1001 (Pure), PK-410 (Hybrid), and EPL-550 (Hybrid), and an integrated system including Primer–Polyurethane–Topcoat (TP-200), optimized system design according to field conditions and consistent quality control are possible.
Performance is secured immediately after application, and since there is no curing process, defects such as bubbles, delamination, and moisture influence do not occur during curing. AP Tech products are field-proven, site-friendly products validated over more than 20 years.
Although the initial cost is high, it is economical in terms of Life Cycle Cost due to reduced construction time, early reopening, and reduced maintenance.
