Protectosil® 200N

• salvent-free, colorless material
• 100% moisture vapor transmission
• No masking of windows required
• effective on micro cracks up to 0.3 mm
• Excellent resistance to chloride ion ingress
• deep penetration into substrate
• resistant to alkali
• mitigation of AAR and ASR detioration
• meets NCHRP, ASTM and AASHTO standards

Recommendations for use - As a water repellent for mineral building materials, especially substrates with higher porosity such as

• Concrete (cast-in-place and precast)
• Brick
• Natural Stone(non-calcareous)

• The substrates to be treated should be air-dry and clean in order to ensure deep penetration of the active ingredient. During application the cutside temperature and the temperature of the substrate should be within the range of 20 °F to 100 °F. The material should not be applied if there is strong wind or if it is raining. The material must not come into contact with water either before or during use. Protectosil 200 N should be applied using low-pressure (15 to 25 psi) pumping equipment with a wet fan type spraynozzle. Alternate methods include using either a power roller with o 1° nap or a brush.
• On vertical surfaces, apply the Protectosil® 200N Nina flooding application from the bottom up, so the material runs down 6 to 8 inches below the spray pattern. Coverage rates on vertical surfaces depend on the type of substrate to be treated. Coverage rates on horizental concrete surfaces are between 100 and 350 ft² /gal.
• All equipment and containers must be clean and dry. After use, they can be cleaned with any organic solvent (mineral spirits, denatured alcohol or thinners). Glass, woad, and netal are not attacked by Protectosil® 200N, therefore it is not required to mask these surfaces off prior to application. It is recommended that windows and other non-porous substrates that will come in contact with be clean to guarantee no residue is left on them after application of Protectosil® 200N.
• Since it is frequently unknown whether the substrate has been previously treated, a test should always be performed on a small area to make sure that no undesired results occur. Plants in the vicinity of the substrate to be treated are to be protected against contact with the waterproofing agent.
• Protectosil® 200N is a combustible liquid and should be kept away from heat, sparks, open flame and other sources of ignition. Protectosil® 200N containers should be kept closed when not in use and should be stored at temperatures between 0°F (-18°C) and 120°F (50°C), away from rain and standing water. When working in an enclosed area, an air respirator should be used.
