The porfil.® principle

Concrete/screed and pores

Mineral building materials consist of cement, water, additives and additional substances – in a varying quality and quantity.
The solidification of the building material starts in the course of the chemical reaction (hydration), and depending on the formulation, densification and other edge conditions (such as ambient temperature and humidity for example) concrete, screed and mortar of different quality and varying pore-sizes are produced. Even high density concretes have pores.

  • The more water, the more pores due to the elusion of exceeding water

porfil.® Characteristics

Conventional techniques for the sealing and durable protection of parts made of concrete, mortar or screed suffer from generally known and already described disadvantages. Inadequate protection, adhesion or cohesion failure are detected time and again.
The pore-filling sealant porfil.® penetrates the building material, protects it from rear surface moisture and seals it resistant to pressurised water. In addition, the mechanical parameters such as abrasion resistance and adhesive pull strength are improved, the deformation behaviour is reduced and the acid resistance (pH>4) of the surface is enhanced.

Conventional method:

Covering of the pore-walls

  • open pores due to the evaporation of solvent or water
  • non-permanent

» insufficient protection

Conventional method:

Layer forming

  • direct mechanical exposure
  • adhesion problems
  • high application rate

» insufficient protection


  • high mechanical resistance
  • curing of fresh (green) concrete
  • no adhesion problems
  • low material consumption

» outstanding protection
