PRATECH® GR108
C2TES2 Ultra Flex Granite Adhesive

It is a cement-based, single-component ultra-flexible adhesive mortar with reduced slip and extended open time, offering a minimum elongation strength of 5 mm or more. It is used for bonding cladding materials such as granite, natural granite, large-format ceramics, porcelain tiles, cotto, and clinker on horizontal and vertical surfaces. Available in two color options: white and grey.

  • Resistant to surface stresses caused by temperature variations.
  • Demonstrates low slip tendency, helping the cladding materials remain in place.
  • As an S2-class flexible product, it offers high adhesive strength.
