Water Repellent Agent – High-Performance Silicone-Based Solution

1. Waterproofing Protection: Forms a hydrophobic barrier to repel water and prevent moisture absorption, enhancing the durability of concrete, brick, stone, and masonry.
2. Anti-Corrosion & Anti-Efflorescence: Prevents salt deposition and chemical corrosion, protecting against freeze-thaw damage to ensure long-term structural integrity.
3. Breathable Surface Treatment: Allows vapor transmission to prevent mold and mildew while maintaining the natural porosity of building materials and blocking liquid water.
4. Enhanced Durability & Longevity: Extends the lifespan of concrete structures, facades, and historical buildings, with resistance to UV degradation, weathering, and chemical exposure.
5. Eco-Friendly & Safe Application: Features a low-toxicity, silicone-based formula that is environmentally safe and easy to apply by spraying, brushing, or rolling on various surfaces.

Water Repellent-Aquago® Packaging

Celotech’s Aquago® is packaged in 25 kg multilayer paper sacks with a polyethylene intermediate layer and an inner P.E. bag. This packaging ensures that the product remains sealed and protected from moisture, which is essential for maintaining its effectiveness. It is recommended to store the product away from direct sunlight and heat sources to preserve its chemical stability.

Frequently Asked Questions

How is the Water Repellent Agent applied?

Common methods include:

Spraying (for large areas)
Rolling or brushing (for precise coverage)
Dip treatment (for prefabricated materials)

How does a Silicone Water Repellent work?

Silicone repellents have low surface tension, allowing them to penetrate porous materials and form a water-resistant layer. They repel liquid water but remain breathable, preventing trapped moisture and damage.

What is a Water Repellent Agent?

A Water Repellent Agent is a protective coating (typically silicone-based) that creates a hydrophobic barrier on surfaces, preventing water absorption while allowing vapor transmission. It is widely used in construction to waterproof concrete, brick, stone, and masonry.

What is the difference between hydrophobic and waterproof agents？

Hydrophobic agents and waterproofing agents are essentially coatings, but their main functions are different. Hydrophobic agents play a role in reducing the surface ability of materials, allowing water to form bead like structures on the surface that are not easily attached, and have the effects of moisture resistance, rust prevention, and corrosion prevention; And waterproofing agents prevent moisture infiltration through coatings, playing a role in preventing concrete, bricks, and other structures from absorbing excessive moisture, protecting buildings or other concrete structures from moisture damage.

Where can Water Repellent Agents be applied?

They are suitable for:

Concrete structures (bridges, parking decks, basements)
Masonry & brick facades
Natural stone & terracotta
Roofs, balconies, and terraces
Historical building restoration

How can you guarantee the quality?

Always a pre-production sample for customer’s checking before mass production; Always final Inspection before shipment.

What’s the difference between a Water Repellent and a Waterproofing Membrane?

Repellents penetrate surfaces, providing breathable protection against water.
Membranes form a thick, impermeable layer (e.g., for roofs/wet areas) but may trap moisture.

Is the product environmentally safe?

Most modern silicone water repellents are low-VOC and non-toxic, making them safe for both indoor and outdoor use. Always check the manufacturer’s specifications.
