DEFIX LATEX B Waterproofing Admixture – A solution to enhance adhesion, reduce cracking, and improve durability for cementitious mortar
In today's construction, waterproofing is no longer just an option but has become a mandatory requirement to ensure the longevity of structures. However, many projects still experience water seepage, peeling, hairline cracks, or rapid deterioration of the mortar layer due to inappropriate materials or incorrect construction techniques. To overcome these issues, using high-quality waterproofing admixtures from the mortar mixing stage is a solution that delivers long-lasting effectiveness.
DEFIX LATEX B is an improved Styrene Butadiene emulsion-based waterproofing admixture, designed to be mixed directly with cement or cement-sand mortar to enhance adhesion, reduce water absorption, superplasticize, and improve waterproofing capabilities for various construction elements. The product is suitable for both civil and industrial projects, helping to elevate construction quality and extend structural lifespan.
What is DEFIX LATEX B?
DEFIX LATEX B is a white, opaque, liquid Styrene Butadiene emulsion-based polymer admixture, commonly used in bonding slurry layers, waterproofing mortar, concrete repair mortar, screeds, masonry mortar, and tile adhesives. When mixed in the correct proportion with cement and water, the product significantly improves the mechanical properties of the mortar, increases adhesion between material layers, and minimizes shrinkage-induced cracking.
The product is packaged in 5kg and 18kg containers, with a shelf life of up to 24 months when stored under dry, cool conditions.
Outstanding advantages of DEFIX LATEX B
One of the reasons DEFIX LATEX B is chosen by many construction units is its ability to comprehensively improve the quality of the mortar layer.
The product helps strengthen the bond between old and new concrete, ensuring the mortar layer adheres firmly to the substrate without easily peeling off. Additionally, the admixture reduces shrinkage during curing, thereby limiting the formation of common hairline cracks after construction.
Moreover, DEFIX LATEX B also increases the elasticity of the mortar layer, enhances abrasion resistance, improves waterproofing capabilities, and maintains stability even in high-alkaline environments. This product is also suitable for mortar layers in contact with domestic water, meeting safety requirements for various construction elements.
Practical applications
DEFIX LATEX B has a wide range of applications in construction.
The product is used as a bonding slurry between old and new concrete, helping to increase adhesion before pouring the next layer of concrete or mortar.
For areas frequently exposed to water, such as rooftops, balconies, bathrooms, water tanks, or screeded areas, DEFIX LATEX B helps create a highly durable waterproofing mortar layer, preventing backflow seepage and surface cracking.
In addition, the product is suitable for concrete repair, patching damaged areas, creating abrasion-resistant coatings, or improving the quality of tile adhesives and ordinary masonry mortar.
Instructions for applying DEFIX LATEX B
For optimal results, the surface must be clean, free of dust, grease, and impurities. For highly absorbent surfaces, saturate with water but do not allow puddles to form before application. The ideal ambient temperature ranges from 8°C to 40°C.
Applying the bonding layer
Mix 1kg of DEFIX LATEX B with 1 liter of water, then add 4kg of cement to create a bonding slurry. This mixture can cover approximately 4m² of surface with a thickness of about 1–2mm. After applying the slurry, immediately apply the concrete or repair mortar while the bonding layer is still wet to ensure maximum bond strength.
Applying waterproofing mortar
Mix cement and sand in a 1:3 ratio. Simultaneously, mix DEFIX LATEX B with water in a 1:3 ratio, then gradually add it to the cement-sand mixture, stirring until a suitable consistency is achieved.
The waterproofing mortar layer must be applied immediately over the bonding slurry while it is still wet. The estimated consumption is about 1kg of DEFIX LATEX B per square meter for a 2cm thick mortar layer.
Why choose DEFIX LATEX B?
Adding waterproofing admixture at the mortar mixing stage not only significantly reduces the risk of water seepage but also enhances bond strength, extends the lifespan of the finish, and reduces future repair costs.
DEFIX LATEX B offers many practical benefits such as easy application, compatibility with various cementitious mortars, improved plasticity, increased crack resistance, and abrasion resistance. This is a suitable solution for residential buildings, apartments, villas, factories, schools, hospitals, as well as many construction elements requiring long-lasting waterproofing.
Some notes on usage
To maximize product effectiveness, always mix cement with the DEFIX LATEX B and water mixture according to the recommended ratio. The surface must be damp but not waterlogged. If applying multiple layers, it should be done while the previous layer is still wet to create the best bond. After completion, tools must be cleaned immediately with clean water. During use, direct contact with skin and eyes should be avoided; if it occurs, rinse thoroughly with water and seek medical attention if necessary.
Conclusion
A quality mortar system depends not only on cement or sand but also significantly on the accompanying admixtures. With its ability to enhance adhesion, reduce shrinkage, effectively waterproof, and improve the durability of the mortar layer, DEFIX LATEX B is a reliable solution for projects requiring high quality and longevity.
