Mixing Sodium Silicate Solution
Determine the Appropriate Concentration of Sodium Silicate Solution
Before mixing sodium silicate solution, it is important to determine the appropriate concentration based on the type of concrete and desired outcome. The concentration of the solution will affect its ability to penetrate the surface and bond with the concrete. It is important to note that a higher concentration does not necessarily mean better results.
In fact, mixing sodium silicate at a higher concentration than recommended can cause the surface to become brittle and prone to cracking. To determine the appropriate concentration, consider factors such as the age and condition of the concrete, its porosity, desired level of penetration, and intended use of treated surface.
Generally, a solution with a lower concentration is suitable for older or more porous concrete surfaces. On the other hand, new or denser surfaces may require a higher concentration for effective penetration.

Mix Sodium Silicate with Water According to Manufacturer's Instructions
After determining the appropriate concentration of sodium silicate solution for your specific project, mix it with water according to manufacturer’s instructions. It is important to follow these instructions closely as they vary depending on product brand and type.
Typically, you will need to add water gradually while stirring continuously until you achieve a homogenous mixture with no lumps or clumps. The ratio of water to sodium silicate should also be carefully measured according to manufacturer’s instructions in order to achieve optimal results.
Once mixed properly, let your sodium silicate solution sit for 10-15 minutes before application in order for it reach maximum viscosity. This will allow for better absorption into porous surfaces such as concrete while minimizing excess runoff during application process.
Curing Process
Allow the sodium silicate solution to cure for at least 24 hours before exposing it to water or other liquids.
After applying the sodium silicate solution on the concrete surface, it is crucial to give it ample time to cure before exposing it to any form of moisture. Typically, a minimum of 24 hours is required for the solution to dry and harden completely. The curing process may take longer depending on factors such as temperature, humidity, and air circulation.
It is recommended that you check the manufacturer’s instructions for specific directions on curing time based on their product specifications. If you expose the treated surface to water or any form of liquid before it has cured adequately, it can result in a weaker bond between the concrete and sodium silicate coating.
Here we have the ultimate guide to curing sodium silicate
This vulnerability can cause delamination or peeling of the surface over time. It is important not to rush this process; allowing ample curing time will ensure maximum effectiveness and durability of your sodium silicate treatment.
During curing process, avoid foot traffic or heavy equipment on the treated surface
During curing time, avoid stepping or placing heavy equipment on the treated surface as much as possible. This precautionary measure will prevent any interference with or damage to your newly-treated surfaces.
Heavy equipment or foot traffic can cause marks that are challenging to remove once they set in during this critical period. It is also essential that you keep pets away from the area because they might scratch up surfaces when walking across them prematurely.
Remember that exposure to rainwater during curing can dilute and wash off sodium silicate coatings; thus dragging out its hardening phase even more significantly than usual. By following these two simple tips religiously during your Sodium Silicate application process, you’ll optimize its durability potential while minimizing risks from premature use before completion of necessary steps!
Water glass, commonly known as soluble alkali metal silicate (or "paohuajian" in Chinese), is a material typically composed of a mixture of alkaline metal oxides (e.g., sodium or potassium oxide) and silicon dioxide. It is widely used in construction and industrial applications.
Classification
Water glass can be categorized based on the type of alkaline metal:
Sodium Water Glass (sodium silicate)
Potassium Water Glass (potassium silicate).
The choice between these types depends on the specific construction materials and requirements.
Key Properties
1、Strong Adhesive Strength:
The adhesive capability increases with the density of the solution.
Adding urea can further enhance its binding capacity.
2、Exceptional Corrosion Resistance:
Resists damage from inorganic acids (e.g., sulfuric acid), organic acids, and corrosive gases.
Often applied as a protective coating on metal surfaces to improve durability.
3、Safety Considerations:
Water glass is inherently corrosive and can cause chemical burns upon skin contact.
Proper safety precautions (e.g., gloves, protective gear) are essential during handling.
The modulus of water glass is a critical parameter, typically ranging between 1.5 and 3.5. A higher modulus indicates greater difficulty in dissolving solid water glass in water. For instance:
When the modulus n = 1, it dissolves easily in room-temperature water.
As n increases, hot water becomes necessary for dissolution.
When n > 3, steam under more than 4 atmospheres of pressure is required for dissolution.
Water glass refers to sodium silicate in its aqueous solution form. It is commonly called water glass in southern China and sodium silicate in northern regions. Sodium silicate solution appears as a colorless or slightly tinted, transparent/translucent viscous liquid when dispersed in water. The solid form exists as colorless or faintly colored glassy blocks and is categorized into three physical states: liquid, solid, and water-quenched (theoretically classified as a colloidal substance).
Solubility varies significantly with modulus and the number of crystalline water molecules present. Here are empirical measurements:
Na₂SiO₃·5H₂O: Actually a tetrahydrate of disodium dihydrogen orthosilicate with two cations. Solubility at 20°C: 50 g/100 g water.
Na₂SiO₃·9H₂O: Contains 58% crystalline water. Solubility at 20°C: 38 g/100 g water.
Na₄SiO₄·nH₂O: Solubility in water at 20°C: 288 g/L.
Producing liquid sodium silicate is straightforward:
Start with solid sodium silicate.
Add water and dissolve it by heating.
While there are minor techniques involved, the process is simple enough for anyone to master within 30 minutes. Homemade liquid sodium silicate is not only cost-effective but also often outperforms commercial products in quality. Detailed technical guides and step-by-step instructions are widely available online.
