Sika Antisol-3E – Curing agent for durable concrete – 25Kg – Milky white

The Sika Antisol-3E is a curing agent specially designed for treating concrete surfaces. This liquid additive is widely used in the construction field to protect fresh concrete and prevent rapid drying issues. It provides an effective solution to retain moisture in concrete, which is crucial to ensure optimal curing and achieve the desired mechanical performance. Below is a detailed overview of the product, including its main characteristics, applications, advantages, and precautions.

Overview of Sika Antisol-3E

Sika Antisol-3E is a ready-to-use liquid based on synthetic resins, used as a curing agent for concrete. It works by forming a thin surface film that limits the evaporation of water contained in fresh concrete. This process is essential to promote proper cement hydration, a key element in ensuring adequate mechanical strength and minimizing the risk of cracking.

This product is particularly recommended for projects requiring controlled curing, especially when concrete is exposed to extreme climatic conditions (heat, wind, or low humidity) that can accelerate evaporation.

Key Properties

Evaporation Limitation:
Sika Antisol-3E significantly reduces the rate of water evaporation, helping to maintain the necessary humidity conditions for continuous cement hydration.

Easy Application:
The product is in liquid form and can be easily applied using sprayers or rollers, even over large surfaces.

Compatibility:
It can be used on various types of concrete, including reinforced concrete, prestressed concrete, as well as decorative or industrial concretes.

Eco-friendly:
The product complies with various environmental standards and is designed to minimize environmental impact while ensuring maximum effectiveness.

Advantages of Using Sika Antisol-3E

Improved Mechanical Properties:
By preventing premature evaporation, the agent allows for complete cement hydration, increasing compressive and tensile strength.

Reduction of Cracks:
Proper curing prevents plastic shrinkage, reducing the risk of surface cracking, which could compromise the structure’s durability.

Preserved Aesthetics:
By preventing cracks and irregularities, Sika Antisol-3E contributes to a better final appearance of concrete surfaces.

Fast Application:
Thanks to its simple and quick application, it saves time on-site and reduces the effort needed for alternative solutions (such as covering with tarps or spraying water).

Flexibility in Climatic Conditions:
This product remains effective even in demanding environments, such as very hot or windy areas, providing a reliable solution for projects in various regions.

Main Applications

Sika Antisol®-3E is used in a variety of construction projects, such as:

Roads and Highways:
Ensures proper curing of concrete pavements, particularly in exposed areas.

Industrial Slabs:
Provides a uniform surface and minimizes the risk of cracks that could affect slab performance.

Hydraulic Structures:
Dams, reservoirs, and other concrete structures exposed to demanding conditions benefit from this curing agent.

Decorative Concrete:
In aesthetic projects such as terraces or public squares, Sika Antisol-3E helps maintain the appearance of concrete.

Instructions for Use

Preparation:
Concrete must be clean and fresh. The product should be well shaken before application.

Application:
Use a sprayer, roller, or brush to apply an even layer as soon as the concrete surface loses its excess water (when the sheen disappears).

Effective Duration:
The film formed by the product remains active for several days until complete hydration. If subsequent finishing is required, the Antisol layer can be removed by sandblasting or washing.

Precautions and Limitations

Compatibility with Finishes:
If coatings (paints, plasters, etc.) are to be applied on the concrete, the Antisol-3E layer must be removed beforehand.

Storage Conditions:
Store the product in a cool place and protect it from freezing. Extreme temperatures can alter its performance.

Safety:
Although the product is low in toxicity, wearing personal protective equipment (gloves, goggles) during application is recommended.
