Specification Clause
When specifying Fosroc Nitocote CM210 for a project, the following clause should be included :
All concrete surfaces requiring waterproofing shall be treated with Fosroc Nitocote CM210 , a two-component , cementitious , acrylic-modified waterproofing coating, applied in accordance with the manufacturer's recommendations .

Application Instructions
Surface Preparation

1. Ensure the substrate is clean, free of dust, grease, and any loose material .
2. Repair any damaged areas, cracks, or voids before applying Nitocote CM210 .
3. Saturate the surface with clean water, ensuring it is damp but free of standing water .

Mixing

1. Add the Nitocote CM210 powder to the liquid component gradually, mixing continuously with a slow-speed drill and paddle attachment .
2. Mix until a smooth, lump-free consistency is achieved, typically within 3-5 minutes .

Mixing Warning
Do not overmix, as this may introduce excessive air into the mixture, affecting its performance .

Pre-wetting of the Substrate

1. Pre-wet the substrate with clean water to ensure it is damp but free of standing water .
2. This step is crucial to prevent rapid absorption of water from the Nitocote CM210 slurry, which may result in a weaker bond .

Application Techniques
Brush Application

1. Apply Nitocote CM210 using a stiff-bristle brush in smooth, even strokes .
2. Apply a minimum of two coats, allowing the first coat to become touch dry (typically 4-6 hours) before applying the second coat .

Roller Application

1. Use a medium-nap roller to apply Nitocote CM210 evenly over the surface .
2. Follow the same two-coat application process as for brush application .

Trowel Application

1. Use a steel or plastic trowel to apply Nitocote CM210, spreading it evenly across the surface .
2. Apply a minimum of two coats, allowing each coat to become touch dry before applying the next .

Spray Application

1. Nitocote CM210 can also be applied using a suitable spray system, ensuring an even application .
2. Follow the same two-coat application process as for other application techniques .

Mechanical Key (Vertical & Horizontal Application)

1. For applications requiring a mechanical key, apply a scratch coat of Nitocote CM210 to the surface and use a comb to create grooves .
2. Allow the scratch coat to become touch dry before applying the subsequent coats .

Sealed Joints

1. Seal all joints, gaps, and penetrations using a compatible sealant, such as Fosroc Nitoseal PU40.

Mock-Up

1. Always conduct a trial application or mock-up to ensure the desired performance and appearance are achieved .
