Surface Preparation:

Concrete surfaces should be clean, free of laitance, dirt, paint, coatings, or other foreign matter. The surfaces should have an open capillary system. Smooth surfaces should be acid-etched, lightly sandblasted, or waterblasted. Any structural defects, such as cracks or honeycombs, must be repaired before applying CP-MoyaProof CWP.

Mixing:

• Mix 25 kg of CP-MoyaProof CWP with 13-14 liters of clean water.
• Always add powder to water and mix using a slow-speed drill fitted with a paddle until a smooth, lump-free consistency is achieved.
• Do not add more water to rework stiff material.

Application:

• Slurry Coat: Apply CP-MoyaProof CWP with a stiff fiber brush to the damp surface, ensuring all pores are filled. Apply a second coat after the first one has set but is still green.
• Dry Shake Method: For newly poured concrete, apply the powder directly over freshly poured concrete (4-5 kg/m²) before final troweling.
• Leaking Cracks: For active water leakage, mix CP-MoyaProof CWP with CP-MoyaProof Plug in a 1:1 ratio to stop the water flow. Apply two coats of CP-MoyaProof CWP afterward.

Overcoating:

• If epoxy coating or painting is required, neutralize the CP-MoyaProof CWP surface using a buffer solution.
• After 21 days, the applied CP-MoyaProof CWP can be mechanically removed to allow coating application.

Curing:

• Keep the surface moist during curing by spraying water 3-4 times daily for 12-15 days.
• Wet hessian or moist sand can also be used to keep the surface damp.
• No protection boards are required once curing is completed.
