Understanding UZIN Waterproofing Types and Their Applications in Various Building Areas
In the construction industry, waterproofing is an essential element in protecting buildings from leaks and water-related damage. UZIN offers several waterproofing systems, including WP 110, WP 220, and WP 120. Each product has unique characteristics and functions tailored to specific application areas.
1. UZIN WP 110 – Elastic & Practical for Interior and Exterior Use
UZIN WP 110 is a ready-to-use elastic waterproofing coating. It is designed for exposed areas such as side walls and rooftops. Application is simple and can be done using a roller or brush, similar to painting.
For optimal results, it is recommended to use two different colors for the two coating layers to ensure even coverage. Once dry, WP 110 forms an elastic membrane capable of bridging cracks up to 300% of the application thickness.
2. UZIN WP 220 – High-Strength 2-Component Waterproofing System
UZIN WP 220 is a two-component waterproofing system consisting of cement-based powder and acrylic polymer liquid. This combination creates a UV-resistant coating that is strong, flexible, and provides excellent adhesion to various surfaces.
3. UZIN WP 120 – UV Protection & Heat Reduction for Exposed Areas
UZIN WP 120 is an Acrylic Polyurethane-based waterproofing system specifically designed for exposed areas. In addition to being waterproof, it also offers excellent UV resistance.
Waterproofing Applications by Area (Q&A)
What waterproofing system is recommended for bathrooms?
For bathroom areas, the recommended system is applying two coats of UZIN WP 220.UZIN WP 220 offers high water resistance, and its cement-based texture allows cement mortar applications such as plaster or screed on top of it. In addition, its elastic properties help bridge hairline cracks and prevent leakage.
It is also important to protect the drain area, especially the gap between the PVC pipe and the concrete floor. The best solution is to apply grout or use a layered system of UZIN WP 110 – reinforcing mesh – UZIN WP 110.
What is the correct waterproofing system for swimming pools?
Untuk kolam renang, disarankan menggunakan sistem berlapis, yaitu:First Layer: UZIN PRIMER
Second Layer: UZIN WP 110
Third Layer UZIN WP 220
This combination provides optimal protection: UZIN PRIMER acts as a bonding agent, UZIN WP 110 functions as the initial elastic crack-bridging layer, while UZIN WP 220 enhances resistance against water pressure and features a cement-based texture that allows screed or tile adhesive to be applied on top.
What waterproofing system is best for rooftops or roof decks?
For rooftops or roof decks, there are two recommended systems:Apply 2 coats of UZIN WP 120 for exposed floor areas.
Apply UZIN WP 110 followed by UZIN WP 220, then protect the system with UZIN SCREED.
Why does a rooftop require UV-resistant waterproofing?
Because rooftops are directly exposed to sunlight and extreme weather conditions, conventional bitumen- and acrylic-based waterproofing systems tend to age and become brittle more quickly.
Using products such as UZIN WP 120 helps protect surfaces from heat-induced cracking because it contains UV-resistant Hybrid Acrylic-Polyurethane technology, extending the material’s lifespan approximately 3–5 times longer compared to conventional waterproofing systems.
Can all waterproofing products be applied without professional assistance?
Technically, yes. However, it is highly recommended to use experienced applicators or professionals who have completed UZIN training.This is important to ensure the waterproofing system performs optimally and to avoid application errors that could lead to future leakage problems.
Each UZIN waterproofing product offers specific advantages and functions. By selecting the appropriate system and ensuring professional application, the risk of leakage can be significantly minimized. Investing in a high-quality waterproofing system not only protects the building structure but also maintains comfort and property value over the long term.
