How to Apply Sodium Silicate on Concrete

Sodium silicate, commonly known as water glass, is a highly versatile compound with extensive applications across various industries. When utilized on concrete surfaces, it acts as a sealant, creating a solid barrier that effectively safeguards against moisture and other external elements.

Furthermore, it offers the remarkable ability to repair and reinforce damaged concrete, forming a strong bond between different layers while improving the overall strength and durability of the structure.

Preparation before applying sodium silicate

Before applying sodium silicate on any concrete surface, it’s important to prepare it thoroughly to ensure maximum adhesion and effectiveness.

Preparing the Concrete Surface

This includes removing any dirt, oil, or debris from the concrete surface.

Start by sweeping the area to remove loose dirt and debris. If there are stains on the concrete surface, use a pressure washer to clean them off.

This will ensure that the sodium silicate can penetrate into the concrete and bond effectively. After cleaning, allow the concrete surface to dry completely before proceeding with the application of sodium silicate.

Any moisture on the surface can interfere with bonding and curing of the solution. Therefore, it is essential to make sure that there is no moisture in or on top of your concrete slab before proceeding.

Repair Any Cracks Or Damage In The Concrete Surface Before Applying Sodium Silicate

The second step in preparing your concrete for treatment is repairing any cracks or damage in its surface before applying sodium silicate solutions. These cracks not only make it harder for you to apply a coat evenly but also provide an avenue for water seepage which corrodes steel reinforcement leading to structural failure. To fix cracks in your concrete slab effectively first clean out any loose debris, then apply a concrete patching compound.

This compound will fill in the cracks and provide a smooth surface that sodium silicate can adhere to. Allow the patching compound to cure for at least 24 hours before proceeding with the application of sodium silicate.
