Lithurin® Hard

Lithurin® Hard

Lithurin® Hard is a deeply penetrating fluid hardener that reacts and strengthens the structure of concrete surfaces. Lithurin® HARD is an impregnator, does not form a surface film and hardens the concrete surface. Lithurin® Hard is water-based and does not change the concrete’s colour. The concrete becomes more resistant to abrasion. A one-off application provides long-term protection. Lithurin® HARD is emissions tested: result (Indoor Air Comfort Gold.) 


Area of application

  • Hardening of concrete surfaces indoors and outdoors
  • Used in combination with Lithurin® DENS, SEAL, PROTEC.
  • Hardens the concrete surface prior to diamond grinding.
