PRATECH® DRZ350
CG2WA-Flex Joint Sealant

Cement-based, high-performance, single-component, easy-to-apply flexible joint filler used in 1–6 mm joints, creating a smooth surface with reduced water absorption and abrasion resistance.

  • Resistant to color fading, dusting, and cracking.
  • Unaffected by sudden temperature changes; suitable for underfloor heating systems.
  • Water-repellent with high abrasion resistance.
  • Possesses strong adhesion properties.
