Nitocote SN522
Nitocote SN522 is a single component, penetrating silane-siloxane which penetrates into porous substrates and then reacts to produce a bonded water repellent lining. Penetrates into substrates. Non staining. Reduces water and chloride intrusion. Increases freeze thaw resistance. Minimises efflorescence. Allows water vapour to escape from the structure. Resistant to atmospheric contaminants.
