Finalit No. 21S Pores Filler (water basis)

  • Pre-treatment for HIGHLY ABSORBANT materials, such as sandstone, limestone, quartzite, concrete stone, terracotta and many more, before applying Finalit impregnations. 
  • Basic protection against stains and soiling. 
  • Consolidator.
  • Use pre-treatment if a underfloor heating is installed. 
  • Use pre-treatment before laying and jointing. 
  • Jointing aid. Bonding agent. Limestone hardener (pyramids and the Sphinx in Egypt). 
  • Sandstone hardener (Petra in Jordan). 

Important! As a pre-treatment for all sides (including edges) before laying, especially suitable for avoiding efflorescence, stains and joint edge discolouration. 

Advantage of treatment on all sides: 

  • Grouting aid
  • Prevents the penetration of moisture and soiling
  • Prevents curling
  • Prevents discolouration & flaking caused by salt, metals and frost.
  • Prevents the penetration of adhesives / silicone with slabs 
  • Makes cleaning easier 
  • Protection for subsequent work, such as painter, carpenter, etc. Does not replace the need of covering against mechanical damage! The drying time is approx. 1 hour. The curing time is 24 hours. 

Can be diluted 1:3 with water. 1 litre is sufficient for up to 50 m², on all sides 20 m², depending on the absorbing properties of the sub-surface.
