Nitocote SN522 water repellent is supplied as a colourless, ready to use, silicone resin solution which can be sprayed or brush applied onto the surface . Nitocote SN522 is a single component, penetrating silane-siloxane which penetrates into porous substrates and then reacts to produce a bonded water repellent lining.Although allowing water vapour to escape from the substrate, it significantly reduces the absorption of water and water-borne salts.
