Fosroc Nitocote SN502 is a single component penetrating silanesiloxane system which penetrates into porous substrates and then reacts to produce a bonded hydrophobic lining to the pores. Although allowing passage of water vapour from the substrate, it significantly reduces the absorption of water and water borne salts.
- Penetrating, hydrophobic silane-siloxane treatment for concrete and masonry
- Does not discolour most substrates and has excellent resistance to weathering

Features & Benefits
- Penetrates into substrates
- Non-staining
- Reduces water and chloride intrusion
- Increases freeze thaw resistance
- Minimises efflorescence
- Allows water vapour to escape from the structure
- Chemically resistant to ice melting compounds, fuels, oils and atmospheric contaminants
Uses
- Protect atmospherically exposed reinforced concrete structures from attack by chloride ions and water intrusion
- Suitable to protect other cementitious substrates and masonry
- Suitable for use on all types of structures, including those in coastal environments
- Equally suitable for new and existing structures
Application Notes
- In order to obtain the penetrating properties of the product, it is important that the correct rates of application and overcoating times are observed
- Should be applied in two flood coats until the recommended total application rate of 0.4 litre per square metre has been achieved, best accomplished by using portable spray equipment of the knapsack-type
- should be allowed to dry for a minimum of 2 hours (at 20°C) before continuing
- Should be removed from tools and equipment using Fosroc Solvent 102 immediately after use
- Coverage rate 5 m2 per litre per coat
Limitations
- Should not be contaminated with water
- Application should not commence if the temperature of the substrate is below 2°C
- May darken some polymer modified substrates and white cement. A trial area is recommended
- Product is flammable. Do not expose to naked flames or other sources of ignition. No Smoking. Containers should be tightly sealed when not in use. In the event of fire, extinguish with CO2 or foam
