FAQ's of Fosroc Nitocote CM210 Waterproofing Chemical, Packaging Type: Bottle & Bag:
Q: How should I mix and apply Fosroc Nitocote CM210 for best results?
A: To prepare Nitocote CM210, blend Part A (powder) and Part B (liquid) using a 3:1 weight ratio (18 kg powder to 6 kg liquid) until a consistent slurry is achieved. Apply the mixture to clean, damp (not wet) concrete using a brush, roller, or trowel in two coats, each about 1 mm thick, allowing the initial coat to set (4-6 hours) before applying the second.
Q: What surfaces and locations are suitable for Nitocote CM210 application?
A: Nitocote CM210 is ideal for waterproofing both internal and external surfaces such as basements, water tanks (including potable water tanks), swimming pools, bathrooms, roofs, and balconies. It adheres well to concrete and masonry, providing durable protection in both residential and commercial settings.
Q: When is the waterproofed area ready for use after applying Nitocote CM210?
A: Initial curing occurs within 4-6 hours, but allow the coated area to cure fully for 7 days before exposing it to standing water, heavy use, or backfilling, to ensure maximum waterproofing performance and membrane strength.
Q: What are the key benefits of using Nitocote CM210 over conventional waterproofing solutions?
A: Nitocote CM210 offers superior flexibility (elongation > 80%), outstanding adhesion, impermeability to water per DIN 1048, and compatibility with potable water. It forms a continuous, seamless barrier, is non-toxic when cured, and resists cracking and chemical attack better than traditional cementitious coatings.
Q: Where should Nitocote CM210 be stored and what is its shelf life?
A: Store unopened Nitocote CM210 packaging in a cool, dry place, protected from direct sunlight, moisture, and frost. The product retains its properties for up to 12 months when properly stored at temperatures below 30C.
Q: How much coverage does a 24 kg pack provide and what is the recommended thickness?
A: A standard 24 kg pack covers approximately 7 square meters at a total 2 mm thickness (applied in two 1 mm coats). Ensure even application to achieve full waterproofing benefits.
Q: What makes Nitocote CM210 suitable for potable water tanks and sensitive environments?
A: Once cured, Nitocote CM210 is non-toxic, low in VOC, and designed to meet the requirements for coating surfaces in contact with potable water, ensuring safe, odor-free, and reliable waterproofing for drinking water storage and sensitive areas.
