Two-component waterproofing agent Z825 is one of the most advanced products in the field of surface isolation and protection against moisture and water penetration. This product is designed based on modern chemical technologies and advanced formulation to deliver optimal and stable performance under various climatic, environmental, and structural conditions. As its name suggests, this material consists of two separate components that are combined at the time of application to provide the final waterproofing properties.
The first component typically includes cement-based powder materials modified with special polymers, while the second component is a liquid containing active polymer resins. The combination of these two components results in a semi-fluid paste or applicable mortar that, once applied to the surface, forms a resistant layer against water, moisture, and vapor penetration. This product is particularly suitable for projects requiring waterproofing against both negative and positive water pressure. Z825 is designed to perform reliably under harsh conditions, including industrial, underground, and humid environments.
Properties and Effects of Z825 Two-Component Waterproofing Agent
Z825 offers a wide range of properties that make it one of the most widely used and trusted waterproofing materials in construction. Key features include:
- Excellent adhesion to various surfaces such as concrete, brick, cement, stone, and even some metals.
- High elasticity, allowing flexibility against hairline cracks and surface volume changes, preventing layer failure.
- Resistance to water pressure from both directions, crucial for applications like water tanks, tunnels, and pools.
- UV resistance, ensuring no yellowing or performance degradation when exposed outdoors.
- Vapor and moisture barrier, preventing mold, fungi, and moisture-related damage.
- Extends the lifespan of structures and prevents premature deterioration in wet or water-exposed areas.
Applications of Z825 Waterproofing Agent
Due to its superior technical features, Z825 is widely used in various construction, industrial, infrastructure, and civil engineering projects. Major applications include:
- Waterproofing of potable water and wastewater concrete tanks, requiring a durable and non-toxic layer.
- Isolation of tunnels and underground retaining walls exposed to negative groundwater pressure.
- Used as a base waterproofing layer before tiling or finishing in swimming pools, jacuzzis, and aquatic areas.
- Waterproofing rooftops, terraces, bathrooms, restrooms, and kitchens to prevent water infiltration to lower floors and adjacent walls.
- Applied in industrial concrete structures like water channels, small dams, and chemical storage chambers due to its chemical and mechanical resistance.
Safety and Storage Guidelines for Z825
Proper safety and storage practices are essential when using Z825. During application, gloves, safety goggles, and masks should be worn to avoid direct contact with skin and eyes. In case of contact, rinse the affected area thoroughly with water and seek medical attention if irritation occurs.
Both components must be stored in sealed containers, away from direct sunlight, freezing, and excessive heat. Ideal storage temperature is between 10°C and 30°C. Do not use damaged packaging. Components should only be mixed at the time of use, and leftover mixed material should not be stored, as the chemical reaction begins immediately and reduces technical properties. Work areas should be well-ventilated, and eating, drinking, or smoking during application should be avoided.
ZarlooChem, the manufacturer, provides complete safety information, instructions, and technical data sheets with the packaging for informed usage.
Consumption Rate of Z825 Waterproofing Agent
Consumption varies depending on project conditions, substrate type, application method, and surface porosity. On average, each layer requires 1.5 to 2 kg per square meter. For two-layer applications, this increases to approximately 3 to 4 kg per square meter.
Usage on Porous and Rough Surfaces
Surfaces with higher roughness or porosity require more material to fill voids. Areas exposed to positive water pressure typically need thicker application, increasing consumption.
Usage on Large Surfaces
In large-scale industrial projects, precise calculations are performed by supervising engineers or technical experts to estimate the required quantity. For small residential or sectional projects, standard packaging units can be used, and consumption estimated based on package instructions.
Important Note
Overuse leads to material waste and increased costs, while underuse compromises waterproofing quality and reduces the protective layer’s lifespan. Consulting sales experts or the technical team of a reputable brand is a reliable way to determine exact consumption.
Why Z825 Is a Reliable Choice for Waterproofing Projects
Z825’s unique chemical composition, strong waterproofing properties, high resistance to water pressure, and ease of application make it an ideal choice for isolating concrete and cement surfaces in construction and industrial projects. Its reliable performance contributes to longer structural lifespan, reduced maintenance costs, and prevention of water damage. Choosing Z825 from ZarlooChem is a smart decision for engineers, contractors, and clients seeking quality, durability, and assurance in waterproofing operations.
