Master Emaco SBR 2 is a styrene-butadiene rubber (SBR)-based polymer emulsion that is widely used as an additive for cementitious materials such as concrete, mortar, and plaster. It acts as a bonding agent that enhances the properties of the base material, improving its performance and longevity. The product is a key component for a wide variety of construction and renovation tasks, offering increased adhesion and improved structural integrity, particularly in challenging conditions.
Master Emaco SBR 2 is compatible with a range of cement-based products and can be used in both repair and new construction projects. It is designed to offer reliable and long-lasting performance in diverse environmental conditions.
Key Features of Master Emaco SBR 2
Master Emaco SBR 2 has several important characteristics that make it an ideal choice for construction projects. Below are the key features that define the product:
Polymer Modification
Master Emaco SBR 2 contains a polymer emulsion that enhances the properties of the base material. When mixed with cement or mortar, the polymer improves the mix’s workability, making it easier to apply and spread. It also promotes a stronger bond between new and old concrete, ensuring better adhesion in repair applications.
Flexibility and Crack Resistance
One of the significant advantages of using Master Emaco SBR 2 is the improved flexibility it imparts to the treated substrate. The polymer emulsion helps reduce the risk of cracking and shrinkage, particularly in repair applications where the new material is subject to thermal and mechanical stresses. The flexibility ensures that the repaired surface can accommodate movements without breaking apart, leading to enhanced durability.
Waterproofing and Protection
Master Emaco SBR 2 also provides enhanced water resistance. When added to cementitious mixes, the polymer forms a barrier that helps to minimize water penetration, offering increased protection against moisture-related damage, which is crucial for applications exposed to external elements. This feature is particularly beneficial for floors, walls, and facades in areas with high moisture content or in outdoor environments.
High Bond Strength
The primary role of Master Emaco SBR 2 is to act as a bonding agent. The product significantly improves the bond strength between different materials, such as between old and new concrete, making it ideal for repair and patching work. This strong bond ensures that the new materials remain intact and durable, even under harsh environmental conditions or stress.
Easy Application
Master Emaco SBR 2 is easy to apply, either as a standalone bonding agent or mixed with other materials. It can be applied using a brush, roller, or spray, depending on the specific requirements of the project. Its user-friendly formulation ensures that both professionals and DIY enthusiasts can use the product with ease, saving time and effort.
Compatibility with Cementitious Materials
The product is highly compatible with a wide range of cementitious materials, including concrete, mortar, screeds, and plasters. This compatibility makes it a flexible solution for various construction needs, as it can be incorporated into different types of repair and construction systems.
Applications of Master Emaco SBR 2
Master Emaco SBR 2 has broad applications in both new construction and repair work. It is a versatile product that can be used in many construction processes, from residential buildings to large infrastructure projects. Below are some of the key applications of Master Emaco SBR 2:
Concrete Repairs
Master Emaco SBR 2 is particularly well-suited for concrete repair applications. It can be used to bond new repair mortars to old concrete surfaces, ensuring that the repairs are durable and long-lasting. Whether it’s a crack repair, surface patching, or full-depth repair, the improved bond strength and flexibility provided by Master Emaco SBR 2 contribute to the success of the project.
Flooring Systems
Master Emaco SBR 2 is used extensively in flooring systems to enhance adhesion, flexibility, and water resistance. It is often mixed with cement-based floor leveling compounds and screeds to improve the substrate’s bond with the new floor covering. This ensures that the floor is smooth, stable, and resistant to cracking under foot traffic or heavy loads.
Waterproofing Applications
When mixed with cementitious materials, Master Emaco SBR 2 enhances their waterproofing capabilities. It is ideal for applications where moisture resistance is essential, such as in basement waterproofing, swimming pools, and other areas exposed to high water activity. The polymer emulsion acts as an effective barrier against water ingress, preventing damage to the structural integrity of the substrate.
External Facades and Exterior Walls
In exterior construction, especially for facades and exterior walls, Master Emaco SBR 2 provides an excellent bond between new coatings and the substrate. It also helps resist the effects of weathering, making it ideal for facades that are exposed to the elements. The product helps protect surfaces from the damaging effects of rain, snow, and UV exposure, prolonging the life of the structure.
Structural Strengthening
Master Emaco SBR 2 is often incorporated into systems used for structural strengthening, particularly in concrete and masonry elements. The enhanced adhesion and flexibility offered by the polymer emulsion help improve the overall stability and durability of the structure. Whether used in combination with other repair mortars or fiber-reinforced polymers (FRP), Master Emaco SBR 2 supports the long-term integrity of the repair or strengthening work.
Decorative Concrete Finishes
For decorative concrete projects, such as stamped concrete, textured coatings, and overlays, Master Emaco SBR 2 can be used to improve adhesion between the base concrete and the decorative layer. The result is a smooth, long-lasting finish that can withstand weathering and wear.
Advantages of Using Master Emaco SBR 2
Master Emaco SBR 2 offers numerous benefits for construction projects, especially when compared to traditional bonding agents or mortars. Below are some of the key advantages:
Increased Durability
Master Emaco SBR 2 significantly increases the durability of concrete and mortar repairs. The polymer emulsion strengthens the bond between materials and reduces the risk of cracking, shrinkage, and delamination. This leads to longer-lasting repairs and structures.
Enhanced Workability
By improving the workability of cementitious mixes, Master Emaco SBR 2 makes it easier for contractors to apply materials with precision. This ease of application reduces labor time and improves the overall efficiency of the project.
Cost-Effective Solution
Although the initial cost of Master Emaco SBR 2 may be higher than other bonding agents, its superior performance and longevity result in lower maintenance and repair costs over time. This makes it a cost-effective solution in the long run.

Application Guidelines and Considerations
While Master Emaco SBR 2 is relatively easy to use, there are several important considerations to ensure the best results. Below are some guidelines for applying Master Emaco SBR 2 effectively:
Surface Preparation
Proper surface preparation is crucial for achieving optimal results with Master Emaco SBR 2. The substrate should be clean, free from oil, grease, dust, and loose particles. Surfaces may need to be dampened before application to enhance bonding. For best results, it is recommended to clean the surface with a wire brush or high-pressure water jet.
Mixing and Application
Master Emaco SBR 2 is typically mixed with cement-based materials like mortar or concrete. The recommended mixing ratio will vary depending on the specific application. For bonding purposes, the product is often applied directly to the surface before applying the repair mortar. It is important to follow the manufacturer’s instructions for mixing and application to achieve the desired results.
Curing
After application, the repair or construction work should be properly cured to ensure the best possible outcome. Curing times may vary depending on environmental conditions such as temperature and humidity. It is generally recommended to protect the treated surfaces from direct sunlight and rapid drying during the curing period.
Health and Safety
While Master Emaco SBR 2 is generally safe to handle, it is always important to follow safety guidelines provided by the manufacturer. Wearing gloves, safety goggles, and a respirator may be necessary when handling or applying the product, especially in enclosed spaces. Proper ventilation should be ensured during the application process.
