Polyurethane sealant FAQs

Polyurethane Joint Sealant is a flexible, high-performance sealant designed for sealing expansion joints in concrete, metal, and masonry surfaces. It provides excellent adhesion, waterproofing, and durability, allowing structures to expand and contract without cracking.

Our high-quality Polyurethane Joint Sealant is ideal for: 

  • Expansion joints in buildings & bridges – Prevents cracks due to movement. 
  • Concrete floors & pavements – Ensures long-lasting joint sealing. 
  • Precast concrete panels & facades – Provides waterproof and flexible bonding. 
  • Roads, highways & airport runways – Withstands heavy traffic and environmental stress. 
  • Basements & water-retaining structures – Prevents leaks and moisture ingress. 

Using Polyurethane Joint Sealant offers multiple advantages: 

  • Highly flexible & accommodates movement – Ideal for expansion joints. 
  • Waterproof & weather-resistant – Protects against rain, UV, and chemicals.
  • Superior adhesion to various materials – Bonds well to concrete, metal, and stone. 
  • Resistant to cracking & peeling – Long-lasting durability in extreme conditions. 
  • Easy to apply & fast curing – Reduces downtime in construction projects. 
  1. Clean the joint surface – Remove dust, grease, and debris. 
  2. Apply primer if necessary – Ensures better adhesion on porous surfaces. 
  3. Insert a backer rod (if required) – Helps control the sealant depth. 
  4. Apply the sealant using a caulking gun – Fill the joint evenly. 
  5. Smooth and shape the sealant – Use a spatula for a neat finish. 
  6. Allow curing – Typically takes 24-48 hours for full strength.
  • Skin formation: 1-2 hours. 
  • Full cure: 24-48 hours, depending on humidity and temperature.
