Single Component, Ultra High Solids, Liquid Applied Silicone Roof Coating

Sikalastic®-500 is a versatile, low VOC, ultra high solids, single-component, liquid applied silicone roof coating. It provides superior UV resistance over a variety of roof substrates.

  • VOC Compliant:  < 50 g/l VOC maximum in California
  • UV resistant: Slows degradation caused by normal weathering, aging, and ultraviolet rays
  • Reflective Top Coat: Can reduce cooling costs by reflecting UV rays. The high reflectivity also helps colors maintain their original appearance, whereas other roof coatings tend to fade and sun bleach at faster rates
  • Waterproof with better ponding water resistance*
  • Durability: Infrequent and low maintenance costs
  • High tensile strength and abrasion resistance
  • Excellent adhesion to a variety of roof surfaces
  • Ease of application - fast and simple to install
  • Can be used to reinforce penetrations and terminations ,and make spot repairs
  • Retains its integrity from -80 °F to 250 °F (-62–121 °C)
  • Accelerator available to shorten cure time
  • Open window (recoat time) maximum 7 days between the coats
*Compared to Acrylic coatings. Standard Practice and requirement for warranty is still to reslope areas where water ponds for more than 48 hours.
