Overview of Water Glass



Water glass, also known as liquid sodium silicate (Na₂SiO₃), is a highly viscous solution that is easily soluble in water and has strong alkaline properties. With its waterproofing, adhesive, surface protection, and anti-corrosion capabilities, water glass is widely used in construction, industry, ceramic production, water treatment, and agriculture.



So, what is water glass used for? It is one of the essential chemicals that help optimize production efficiency, save costs, and enhance product quality in many fields.

Applications of Water Glass in Construction



Waterproofing Concrete and Cement Surfaces



Using water glass in construction is an effective waterproofing method that protects concrete, cement walls, and water reservoirs from the effects of water and the environment. When applied correctly, water glass penetrates the capillaries of concrete, creating a protective layer that enhances durability and reduces cracking over time.



What is water glass used for in construction? This chemical improves waterproofing capabilities and enhances the durability of construction projects.



How to use water glass:




  • Clean the surface thoroughly, removing dust and grease before application.


  • Dilute at a ratio of 1:4 (1 part water glass, 4 parts water).


  • Apply two even coats to ensure adhesion and enhance waterproofing.


  • Allow to dry for at least 24 hours before use.







Reinforcing Cement – Enhancing Concrete Durability



In addition to waterproofing, water glass helps reinforce concrete and cement, improving load-bearing capacity and reducing shrinkage and cracking.



What are the benefits of using water glass in construction? Besides waterproofing, it also increases cement hardness and reduces damage.



How to use water glass:




  • Mix water glass directly into cement at the appropriate ratio.


  • Apply in foundation, bridge, and factory floor projects to enhance durability and load-bearing capacity.



Applications of Water Glass in Industry



Metals like iron, steel, and aluminum are prone to oxidation and corrosion when exposed to moisture and chemicals. Water glass helps create a protective layer, preventing rust and extending material lifespan, thereby significantly reducing maintenance costs.



What is water glass used for in industry? One of its common applications is protecting metals from corrosion and oxidation.



How to use water glass:




  • Clean the metal surface, removing grease and dust before coating.


  • Use pure water glass or dilute it 1:1 with water.


  • Apply evenly to the metal surface, allow to dry, and check adhesion.



Industrial Adhesive in Ceramic, Glass, and Heat-Resistant Material Production



In ceramic, heat-resistant material, and welding rod production, water glass acts as a binding agent, enhancing durability, reducing breakage, and improving product quality.



What are the benefits of using water glass in industry? Besides protecting metals, it also enhances adhesion in heat-resistant material production.



How to use water glass:




  • Use pure water glass or dilute it with water as per technical requirements.


  • Apply to ceramic, glass, or metal surfaces before firing or welding.


  • Allow to dry naturally or apply heat to enhance adhesion.



Applications of Water Glass in Agriculture



Protecting Crops from Fungal Diseases and Pests



A lesser-known application of water glass is protecting crops from fungal diseases and insects, reducing the use of harmful chemicals. When sprayed on plants, water glass creates a biological protective layer, helping plants resist bacteria, fungi, and pests.



What is water glass used for in agriculture? It helps protect crops and enhances their natural resistance.



How to use water glass:




  • Dilute 1:20 with clean water.


  • Spray evenly on plant stems and leaves in the early morning or late afternoon for best results.

Soil Improvement, Moisture Retention, and Fertilizer Efficiency Enhancement



Water glass helps improve soil structure, retain water longer, reduce fertilizer leaching, and enhance nutrient absorption by plants.



What are the benefits of using water glass in agriculture? It helps soil retain moisture and improves fertilizer efficiency.



How to use water glass:




  • Dissolve water glass in water at the appropriate ratio.


  • Water evenly onto the soil to promote better plant growth.



Benefits of Using Water Glass in Business



Applying water glass in practice not only brings high efficiency in construction, industry, and agriculture but also helps businesses reduce maintenance costs, enhance product durability, and improve production efficiency.




  • For construction contractors: Using water glass improves waterproofing, extends project lifespan, and reduces repair costs.


  • For manufacturing plants: Water glass protects metal surfaces, reduces machinery wear, and enhances product quality.


  • For agricultural businesses: Using water glass in soil treatment and crop protection reduces reliance on harmful chemicals and increases crop yield.

Is water glass toxic? Is it safe to use?


Water glass (Sodium Silicate) is not acutely toxic but has strong alkaline properties, which can cause skin and eye irritation upon direct contact. When using, wear gloves, safety goggles, and avoid direct contact with skin or inhaling excessive fumes. In agriculture, water glass should be diluted correctly to avoid affecting crops and the environment.
Safety notes:
Wear protective equipment during application or use.
Avoid direct contact with eyes and skin.
Store in a dry place, out of reach of children.



Can water glass completely replace traditional waterproofing materials?


Although water glass is an effective waterproofing solution, it cannot completely replace traditional materials like epoxy paint, asphalt, or polyurethane membranes. Water glass works well on concrete and cement surfaces but is not suitable for materials with high elasticity like plastic or wood.
How to combine for optimal effectiveness:
Use water glass as an internal waterproofing layer.
Apply an additional specialized waterproofing layer externally for comprehensive protection.
Conduct regular checks to ensure long-term durability.



Why does concrete or cement mixed with water glass become brittle?


When mixing water glass with concrete or cement, incorrect ratios can make the material brittle and prone to cracking. This is because water glass increases bonding strength but reduces the mixture's flexibility.
How to fix:
Dilute correctly (as per manufacturer's recommendations).
Combine with additives to enhance flexibility and elasticity.
Test samples before widespread application.



Can water glass protect wood from termites and mold?


Yes! Water glass can create a protective layer on wood surfaces, preventing termites, moisture, and mold growth. However, for optimal results, proper application is required.
How to use water glass for wood:
Step 1: Clean the wood surface, removing dust and grease.
Step 2: Dilute water glass with water at a 1:5 ratio.
Step 3: Brush or spray onto the wood surface, allowing it to dry naturally.
Step 4: Apply additional protective paint or waterproofing oil if needed.



Can water glass be used for industrial wastewater treatment?


Yes! Water glass is used in wastewater treatment due to its ability to precipitate heavy metals, remove impurities, and stabilize pH. In industrial wastewater treatment systems, Sodium Silicate helps reduce turbidity and improve sedimentation efficiency.
Practical applications in wastewater treatment:
Heavy metal removal: Precipitates iron, aluminum, lead, zinc...
pH stabilization: Helps maintain optimal pH in treatment systems.
Reducing sludge: Supports faster coagulation and sedimentation.
