MIKUR mainly produces silicone hydrophobic agent for a wide range of applications. They can be used in concrete, dry-mix mortar, rendering mortar, and other cement-based materials to meet different project requirements for water repellency, water resistance, and weather durability.
This silicone hydrophobic agent is one of our main products for building protection. It is mainly used in exterior wall rendering, waterproof mortar, decorative concrete, road engineering, and other inorganic building material applications. It helps reduce water penetration into the substrate, improving moisture-related problems and reducing the risk of leakage, efflorescence, mold growth, and substrate corrosion.
In addition to standard models, we can adjust the product solution according to the substrate type, application environment, and performance requirements of each project. The product offers stable performance and good compatibility with cement-based materials. After application, it does not significantly affect the substrate’s original strength, breathability, or appearance, while helping maintain its inherent characteristics.
To help ensure reliable application results, we also provide free samples, dosage and formulation guidance, and on-site formulation adjustment support. Selecting the right product and dosage for the specific material and project conditions can provide stable water-repellent and water-resistant performance and, to some extent, help extend the service life of building materials.

Internal Water Repellency
Mikur Silicone Hydrophobic Agent uses a targeted penetrating formulation for porous cement-based materials such as concrete, dry-mix mortar, cement rendering, and inorganic stone. After application, the active ingredients penetrate into the substrate and react with its mineral components to form a water-repellent protective structure. Unlike treatments that rely only on a surface coating, this approach helps protect the material from within and is less prone to peeling or blistering caused by everyday abrasion, rain, and long-term exposure to sun and wind. It is therefore well suited to applications where long-term protection is important.
Key benifits:
Surface Water Repellency
After proper curing and hardening, Mikur Silicone Hydrophobic Agent forms a uniform micro- and nanoscale water-repellent protective film on cement-based substrates, stone, and wall surfaces. Rain, dew, condensation, and cleaning water form droplets on the treated surface and run off more readily, reducing standing water and residual water films. Good water repellency also helps limit dirt buildup, dark staining, water marks, mold, and efflorescence caused by prolonged exposure to moisture, making subsequent cleaning and maintenance easier. It is suitable for exterior walls, roofs, and landscape materials.
Key benifits:
Moisture and Water Resistance
This product helps reduce capillary water rise within the substrate and the entry of external rainwater, minimizing the effects of moisture on cement-based materials. It can help reduce moisture-related risks in concrete, mortar, and walls under rainy weather, high humidity, underground dampness, and saline or alkaline moisture conditions, while improving problems such as dampness, water penetration, mold, efflorescence, surface peeling, hollowing, and cracking. By improving the pore structure and compactness of the substrate, it can help maintain mechanical performance and slow aging, powdering, and corrosion. It is particularly suitable for rainy regions, underground projects, coastal environments with high salt spray, and humid industrial facilities.
Key benifits:
Clear Protective Effect
Mikur Silicone Hydrophobic Agent uses a clear modified silicone formulation without added pigments or fillers. Once cured, it does not form a heavy surface layer and has little impact on the substrate’s original color. When used on concrete, exterior wall mortar, natural stone, cultured stone, and decorative wall surfaces, it helps retain the original texture, color, and finish, making it suitable for building materials where appearance matters. The product also maintains good breathability and water-vapor permeability: while limiting liquid water entry, it allows moisture inside the substrate to escape, helping reduce the risk of hollowing, cracking, and delamination caused by trapped moisture.

Application: Concrete Roof Waterproofing and Renovation
MIKUR silicone hydrophobic agent was used in a large roof renovation project in East China. Through on-site spray application and formulation testing, the hydrophobic agent penetrated the capillary pores of the concrete and formed a water-repellent protective layer, reducing substrate water absorption by more than 35% and helping reduce rainwater penetration, efflorescence, and mold growth. After four years of outdoor exposure, the project had accumulated savings of more than RMB 950,000 in roof leakage repair costs.
Application: Coastal Port Infrastructure in Southeast Asia
MIKUR supplied two containers of silicone hydrophobic agent for a coastal port infrastructure project in Southeast Asia. The products were safely delivered to the construction site by sea and inland transportation. The selected hydrophobic agent provided a penetration depth of ≥3 mm, good retention of water repellency, and salt-spray resistance. It is suitable for high-temperature, high-salinity coastal environments, helping reduce the rate of chloride-ion penetration and delay corrosion of reinforcement inside concrete, providing long-term protection for port structures.
硅酮疏水剂是一种用于水泥基和矿物基干混材料的干粉状疏水添加剂。当材料与水接触时，其活性成分会释放出来，并在基体内部形成疏水结构。这可减少毛细作用引起的吸水，并有助于提高耐水性和长期耐久性。.
硅酮疏水粉广泛应用于各类水泥基和矿物基建筑材料，包括防水砂浆、外墙外保温砂浆（ETICS/EIFS）、瓷砖填缝剂和接缝填充剂、修补砂浆、装饰砂浆、彩色砂浆、微水泥、预制混凝土以及矿物基粉末涂料。 此外，在需要硅酮疏水效果的干混配方中，也可使用该产品。.
在干混砂浆中，硅酮疏水剂有助于降低吸水率和水分渗透，同时提高疏水性。它还能降低泛碱的风险。由于其以粉末形式供应，可直接与水泥、砂及其他干料混合，便于工业砂浆的生产。 对于需要添加砂浆疏水剂的配方，应通过配方测试确认其最终性能。.
合适的用量取决于具体用途、原材料、配合比以及目标吸水率。应综合考虑水泥类型、砂的特性以及配合比中的其他成分。 建议在正式生产前进行实验室试验，以确定合适的产品等级和用量。某些同类产品的典型用量范围约为0.1%–1.0%，但实际用量应遵循产品的技术数据和配方测试结果。.
Yes. Silicone hydrophobic powder can be formulated with RDP (redispersible polymer powder), cellulose ethers, and other dry-mix mortar additives. Their functions are different: the hydrophobic powder mainly reduces capillary water absorption, while RDP contributes to bonding, flexibility, and film formation. The right ratio should be established through formulation trials to balance water repellency, bond strength, and workability.
Yes, it can help reduce the risk of efflorescence. Moisture moving through a cement-based material can carry soluble salts toward the surface; when the moisture evaporates, those salts may appear as efflorescence or whitening. By reducing capillary water absorption and moisture movement, silicone hydrophobic powder can lower this risk. However, efflorescence is also affected by cement, aggregates, curing conditions, and ambient humidity, so a hydrophobic additive alone cannot eliminate the problem completely.
At a suitable dosage and with a compatible formulation, silicone hydrophobic powder can improve water repellency while maintaining good workability. The effects on flow, setting time, and strength can vary with the product and the overall formulation, so practical testing is recommended. Avoid excessive dosage to maintain a good balance between water repellency and mechanical performance.
Store silicone hydrophobic powder in a dry, cool, well-ventilated place and protect it from moisture and direct sunlight. During production, blend it thoroughly with cement, sand, and other dry ingredients so the active ingredients are evenly distributed. Storage life, packaging, and handling requirements should follow the applicable TDS and SDS.
For projects that require a silicone water repellent or a water repellent for mortar, product selection and dosage should be matched to the substrate, formulation, and required performance. MIKUR can provide product samples, dosage guidance, and formulation support for application testing.
