MasterProtect H 303 — hydrophobic impregnation for long lasting invisible concrete protection

 


Formerly: Masterseal 303



What is MasterProtect H 303?

MasterProtect H 303 is a single component, ready to use, low viscosity, clear liquid based on alkyl alkoxysilane emulsion which can be easily spray applied with simple equipment. It penetrates into concrete and significantly reduces water ingress and chloride ion penetration into the concrete. It is a breathable vapour permeable treatment.

MasterProtect H 303 is the first choice to protect concrete where water absorption has to be reduced. To reduce water absorption of concrete is helpful for concrete structures like

  • Commercial, residential and industrial buildings with exposed concrete
  • Sports stadia
  • Cooling towers and water towers
  • Bridges and highways

What makes MasterProtect H 303 a unique solution?

MasterProtect H 303 significantly reduces water ingress and chloride ion penetration into the concrete. Therefore it protects against freeze/thaw damages and de-icing salt attacks and concrete deterioration is delayed. While it penetrates deep into the concrete it does not form a layer on the concrete surface. The original appearance of the concrete surface remains unchanged.

​Long term aesthetic protection, longer maintenance cycles will delay the concrete deterioration considerably.
