Sikalastic® PU Liquid Applied Membrane Systems

At Sika, we are dedicated to innovation and strive to not only develop new cutting-edge technologies but also enhance existing ones. The Sikalastic® PU range of coatings is a one-part, cold-applied, moisture-triggered liquid waterproofing membrane that cures to form a seamless, long-lasting and weather-resistant solution for roof areas that are exposed. These products possess the inherent advantages of liquid membranes and are also a cost-effective alternative compared to other solutions on the market.

Our Sikalastic®-625 N is Sika's most versatile liquid-applied polyurethane membrane suitable for various applications, such as flat, commercial, and industrial roofs, as well as balcony walkways. Our patented i-cure technology enabled us to improve the Sikalastic®-625 N range, which offers a number of benefits such as:

  • Improved temperature stability
  • Longer shelf life
  • Enhanced workability
