Interested in finding out more about our Concrete Densifiers and Sealers?


Concrete Densifiers

NP7937 Concrete Densifier
This is a one component water based lithium based solution designed to densify cement and concrete substrates. The lithium based densifier reacts with the cementitious ingredients to densify while allowing deep penetration to chemically harden and fortify the susbtrate.
This product increases durability by improving resistance to freeze thaw effects, seals against moisture damage, and reduces efflorescence of natural stone, precast stone, and cement.

NP7940 Concrete Conditioner
This is a one component, water based, ultra small particle size, self-cross linking, hydrophobic organic polymer and silane/siloxane designed specifically for use in the grind and polish process. NP7940 works as a surface conditioner and stain guard, and should be applied before the final polishing step.  It helps to increase long term performance, gloss, and stain resistance.


Acrylic Water Based Concrete sealer

NP8400 Water Based Acrylic Sealer
NP8400 is a one component clear water based sealer that offers excellent resistance to water blushing without the objectionable solvent odors associated with solvent based sealers.
