  • What is a polyurethane sealant?
    What is a polyurethane sealant?A polyurethane sealant is a flexible material that seals and bonds joints. It sticks to concrete, metal, wood, and masonry. It handles movement and weather.
  • Where can I use it?
    Where can I use it?Use on windows, facades, roofs, gutters, concrete slabs, driveways, bathrooms, and kitchens. It suits indoor and outdoor jobs.
  • What is a waterproof polyurethane sealant?
    What is a waterproof polyurethane sealant?A waterproof polyurethane sealant resists rain, splash, and standing water. Use on roofs, balconies, wet areas, and around drains. Check immersion limits.
  • What is a construction polyurethane sealant?
    What is a construction polyurethane sealant?A construction polyurethane sealant is built for expansion joints. It handles movement, traffic, and weather. Pick the right movement class for the joint.
  • What is a polyurethane adhesive sealant?
    What is a polyurethane adhesive sealant?A polyurethane adhesive sealant seals and bonds in one step. Use on flashings, trims, metal roofing, and facade panels. It saves time and hardware.
  • Do I need a primer?
    Do I need a primer?Often yes. Prime porous or glossy surfaces for better bond. Follow the brand data sheet. Do a small adhesion test first.
  • How long does it take to cure?
    How long does it take to cure?Skin time is about 30–90 minutes. Full cure is about 24–48 hours. Depth, humidity, and temperature change these times.
  • Can I paint over polyurethane sealant?
    Can I paint over polyurethane sealant?Yes, once cured. Use compatible paints. Do a test patch. Light sanding can help paint grip.
  • Which modulus should I choose?
    Which modulus should I choose?Low modulus for moving joints. High modulus for stiffer joints and facade details. Match modulus to joint size and movement.
  • Is it UV resistant?
    Is it UV resistant?Some grades are UV stable. Choose a waterproof polyurethane sealant with UV rating for exterior work. Non-UV grades can yellow outdoors.
  • How much do I need?
    How much do I need?Estimate by joint math: length × width × depth. Use a joint calculator. 300 ml cartridges vary by joint size. Add backer rod to control depth.
  • How do I repair a failed joint?
    How do I repair a failed joint?Cut out the old sealant. Clean and dry the joint. Fit backer rod or bond breaker. Prime if required. Refill with fresh polyurethane sealant.
