Usage

Sikagard®-905 W is used to prevent damp in plastered or rendered surfaces, brick or stone. Due to its low viscosity, it penetrates deeply into the substrate and forms an invisible water damp-proof barrier.
  • Saltpetre treatment
  • Prevention of mould growth by reducing the water absorption.
  • Damp-proofing and surface hardening
  Sikagard®-905 W is also used as a surface hardener for weak and dusty substrates, both indoors and outdoors.
Sikagard®-905 W can be used as a pre-treatment improving surfaces for painting works on weak or dusty surfaces.
