Introduction
Concrete curing is a critical step in the construction process, directly impacting the strength and durability of the structure . One product that stands out in this domain is Fosroc Concure WB , a reliable curing compound manufactured by Fosroc Chemicals India Pvt. Ltd . Whether you’re working on large surfaces like pavements or sloping surfaces on towers and columns, Concure WB ensures a consistent, high-quality curing process . Additionally, Space Arc Engineering serves as an authorized distributor and applicator of Fosroc products in India, providing expert solutions to construction needs .

What is Fosroc Concure WB?
Fosroc Concure WB is a water-based wax emulsion designed to retain moisture in freshly cast or exposed concrete surfaces . This compound forms a temporary membrane, effectively preventing rapid water evaporation , which is crucial for the curing process. Available in both clear and white variants, Concure WB is a versatile product for use on a variety of construction surfaces .

The Importance of Concrete Curing 
Curing is essential in ensuring the cement in concrete fully hydrates , which gives the structure its strength and durability . Without proper curing, concrete can crack, shrink, or develop surface imperfections , all of which reduce its lifespan. Fosroc Concure WB helps overcome these issues by maintaining sufficient moisture levels throughout the curing period .

Main Uses of Fosroc Concure WB
Fosroc Concure WB has several key applications:

• Freshly cast concrete: It helps retain moisture on new concrete surfaces .
• Newly exposed concrete surfaces: Particularly useful after removing formwork .
• Large concrete areas: Ideal for use on pavements, runways, and bridge decks .
• Vertical or sloping surfaces: Effective on towers, chimneys, columns, and beams, where traditional water curing methods are often unreliable .

Advantages of Fosroc Concure WB
When it comes to construction, reliability and ease of application are paramount . Fosroc Concure WB offers several advantages:

• Single application: A one-time spray creates a moisture barrier for the entire curing period .
• No need for additional curing methods: Eliminates the need for water, hessian, or sand.
• Ensures efficient hydration: Reduces the risk of poor or uneven curing .
• Prevents cracks and dust formation: The product minimizes drying shrinkage and prevents dusty surfaces.
• Non-toxic and non-flammable: Safe to use, easy to apply by spray .

Properties of Fosroc Concure WB
The technical properties of Fosroc Concure WB make it highly efficient :

• Density: 1.00 to 1.01 g/cc
• Water loss: Less than 0.55 kg/m², as per ASTM C156 .
• Reflectance: More than 60%, ensuring minimal water loss .
• Drying time: Less than 4 hours, allowing for quicker completion .
• Application temperature: Suitable for temperatures down to 10°C.

How Fosroc Concure WB Works
Once applied, Fosroc Concure WB forms an impermeable membrane over the concrete surface .  This membrane retains the moisture necessary for cement hydration , ensuring that the concrete cures evenly and efficiently . Over time, the membrane naturally breaks down due to weather exposure, but by then, the concrete has already achieved sufficient strength .

Applications of Fosroc Concure WB
Concure WB is ideal for :

• Large surfaces: Including pavements , bridge decks, and runways,  where traditional curing methods are impractical .
• Vertical and sloping surfaces: Such as towers and chimneys, where water curing is challenging .

The Spray Application Method
To ensure uniform application:

• Use knapsack or motorized sprayers to create a fine mist .
• Holding the nozzle around 450mm away from the surface is recommended .
• Pass the spray back and forth to ensure even coverage .

The recommended coverage rate is between 3.5 to 5.0 sq.m/litre.

Standards Compliance of Fosroc Concure WB
Fosroc Concure WB complies with international standards, particularly ASTM C309 . This ensures that the curing compound meets global benchmarks for performance and efficiency .

Durability and Longevity
The temporary membrane formed by Concure WB breaks down naturally over time , typically through weathering . This ensures that no residue interferes with the concrete’s finish or future treatments .

Fosroc Concure WB as a Debonding Agent
Besides curing, Concure WB can also serve as a debonding agent. When applied between old and new concrete , it forms a barrier that prevents the two surfaces from bonding, allowing for easier construction work .

Equipment for Application
You can use a variety of equipment kinds, such as :

• Spray equipment: Knapsack or motorized sprayers are preferred for large areas .
• Brush or roller: Fine hair brushes or short-nap cotton rollers can be used for smaller areas or vertical surfaces .

Cleaning the Equipment After Use
Immediately after use , it’s important to clean the spray equipment thoroughly with fresh water . For blocked nozzles, white spirit or similar fluids can be used to clear any wax particles .

Packaging and Storage of Fosroc Concure WB
Fosroc Concure WB is available in :

• 5-litre, 20-litre, and 200-litre drums .

It has a shelf life of 9 months when stored between 5°C and 35°C . Containers should  be kept airtight to prevent surface evaporation and should not be exposed to freezing conditions .

Health and Safety Guidelines
Although Fosroc Concure WB is non -toxic and non-flammable , basic precautions should be followed :

• Wear goggles: To protect eyes during spray application .
• Avoid inhalation: Use a mask if working in enclosed spaces .
• Skin contact : Wash with clean water and apply a conditioning cream .

Fire Safety and Handling
Since Concure WB is water-based, it poses no fire hazards , making it safe for use in a variety of environments .

Support and Technical Assistance
Fosroc offers comprehensive technical advisory services , including on-site support and training in the proper application of Concure WB and other products .
