NanoSet Densifier NS™ is an advanced blend of reactive nano silica that penetrates polished concrete deeply and efficiently to increase surface density and hardness, as well as provide additional protection and longevity of the polished concrete substrate.
NanoSet Densifier NS improves the bond between coatings and treated concrete or mortar surfaces; it reduces the occurrence of peeling, cracking and loss of bond caused by capillary moisture or internal chemical reactions.
nano-sized silica particles (5 nm)
"The water-based formulation has concentrated nano-sized silica particles (5 nm) with a pH of 9.5 that permanently bonds with existing concrete chemicals, offering incredible protection and longevity." (see product link)
