Fosroc Nitoproof 725, 20L, Concrete Curing Compound for Reduced Water Loss - Grey

The system comes as a powder and a liquid. Mix the powder with the liquid following Fosroc’s mixing instructions to achieve a uniform, workable coating. Apply with a brush or roller to brick and concrete surfaces as directed.

It is suitable for brick and concrete surfaces and can be used on both internal and external walls and floors where waterproofing or damp proofing is required.

It forms a flexible, seamless membrane that resists water infiltration, splashes and can withstand immersion in water. The formulation also provides weather and UV resistance to protect the substrate.

Yes. The flexible, elastic formulation is suitable for both vertical and horizontal applications.

The coating is designed for long‑term protection, with durability claimed up to about 10 years under correct use and exposure conditions.

Prepare the surface by cleaning it and ensuring it is sound and free of loose material. Mix the two parts to a smooth, uniform coating, then apply with a brush or roller to form a continuous membrane. Allow curing and apply additional coats if required to achieve full coverage.

Wear appropriate PPE such as gloves and eye protection. Ensure good ventilation during application, avoid skin or eye contact, and follow the Safety Data Sheet guidelines for storage and handling.

It provides a long lasting, two‑part cementitious waterproofing solution that dries to a flexible membrane, reducing the need for frequent rework on damp or water‑exposed surfaces, and it’s suitable for both internal and external use, offering long term durability.

When you need a seamless, monolithic coating over irregular surfaces or details where sheet membranes may be impractical, and you require a cementitious system that bonds to brick and concrete with long term waterproofing and moisture control.

Inspect the coated surface after initial cure for uniform coverage with no pinholes or misses. Ensure the membrane is continuous and protected from damage during cure, and follow any re‑coating guidelines provided in the technical data.
