Why Do Tiled Surfaces in UAE Buildings Often Suffer from Water Damage and Mold?
In the demanding environment of UAE construction, where high temperatures and humidity are constant challenges, tiled surfaces in bathrooms, kitchens, and outdoor areas are prone to water infiltration and subsequent damage. Leaks can lead to costly repairs, structural issues, and unhealthy mold growth. This is a critical concern for hardware suppliers and construction professionals who need reliable solutions to ensure project longevity and client satisfaction.

Silicon Sealant: The Essential Solution for Waterproofing and Durability
Silicon sealant emerges as the premier choice for sealing tiles, offering exceptional flexibility, adhesion, and resistance to UV rays and moisture. Its application creates a waterproof barrier that prevents water from seeping into gaps, protecting underlying structures and maintaining aesthetic appeal. For hardware exporters and construction teams in the UAE, understanding the proper use of silicon sealant is paramount to delivering high-quality, durable results that withstand local climatic conditions.
How It Is Made: From Raw Material to Finished Product
Raw Material(s): The primary materials include silicone polymers (derived from silica sand), cross-linkers, fillers like calcium carbonate, and catalysts such as platinum or tin compounds, along with pigments for color.
Manufacturing Process: The process begins with the polymerization of silicone raw materials, followed by mixing with fillers and additives in high-shear mixers. This mixture is then extruded or molded into cartridges or tubes. Curing agents are incorporated to facilitate cross-linking upon exposure to atmospheric moisture. The product undergoes quality checks before packaging.
Key Properties Derived from Manufacturing: The manufacturing process imparts essential properties like flexibility, allowing the sealant to accommodate tile movement without cracking, and adhesion strength, ensuring a long-lasting bond to various surfaces. Additionally, it provides excellent water resistance and UV stability, crucial for outdoor applications in the UAE.
Quality Control: Typical quality checks include testing for viscosity, extrusion rate, skin-over time, adhesion strength, elongation capacity, and resistance to environmental factors. Compliance with standards such as ASTM C920 ensures reliability and performance.
Essential Uses in the UAE Construction Landscape
Primary Application(s): Silicon sealant is primarily used for sealing joints between tiles in wet areas like bathrooms, showers, and kitchens to prevent water penetration. It is also applied in expansion joints on tiled floors and walls, around sinks, bathtubs, and in outdoor tiled areas to combat thermal expansion and moisture ingress, which are common issues in UAE’s climate.
Top 10 Mistakes to Avoid When Applying Silicon Sealant on Tiles
1. Inadequate Surface Preparation: Failing to clean and dry surfaces thoroughly can lead to poor adhesion. Always remove old sealant, dust, and grease using appropriate cleaners.
2. Using the Wrong Type of Sealant: Not all silicon sealants are suitable for tiles. Ensure you use a product designed for high-moisture environments and compatible with tile materials.
3. Ignoring Weather Conditions: Applying sealant in extreme heat or humidity can affect curing. Aim for moderate temperatures and avoid direct sunlight during application.
4. Incorrect Application Technique: Apply in a continuous bead without breaks, and use a smoothing tool or finger (dipped in soapy water) to create a neat finish and ensure full contact.
5. Skipping the Backer Rod for Wide Joints: For joints wider than 1/2 inch, use a backer rod to prevent excessive sealant depth and ensure proper curing.
6. Rushing the Curing Process: Allow sufficient time for curing as per manufacturer instructions—typically 24 hours before exposing to water.
7. Overlooking Compatibility Tests: Test the sealant on a small area first to check for adhesion and color fastness, especially with natural stone tiles.
8. Applying Too Thick or Too Thin: Maintain the recommended thickness (usually 1/4 to 1/2 inch) to balance flexibility and durability.
9. Neglecting Safety Precautions: Wear gloves and ensure ventilation, as some sealants emit fumes during curing.
10. Forgetting Regular Maintenance: Inspect sealed areas annually and reapply as needed to maintain protection, particularly in high-traffic zones.
