Advantages of Sealing Concrete After Pressure Washing

Concrete is one of the most durable and versatile building materials known to man. However, like all materials, it too requires adequate maintenance and protection to ensure its longevity and to maintain its aesthetic appeal. One of the most effective maintenance processes is pressure washing followed by the application of a penetrating sealer. This process not only keeps concrete clean but also offers a multitude of benefits that contribute to the preservation of the concrete's structural integrity. Here, we delve into the advantages of using a penetrating sealer on your concrete surfaces after pressure washing.

1. Enhanced Durability

A key advantage of using penetrating sealers on concrete is the enhanced durability they offer. By penetrating the surface, these sealers form a protective barrier within the concrete rather than just on the surface. This barrier is capable of protecting the concrete against harsh weather conditions, preventing the freeze-thaw cycle damage, and reducing the impact of de-icing salts, thereby extending the lifespan of the concrete.

2. Resistance to Salt Damage

Concrete surfaces, particularly those exposed to de-icing salts or saltwater, can suffer from salt damage, which often leads to surface scaling or sub-surface damage. Applying a penetrating sealer after pressure washing can provide effective protection against salt damage. These sealers penetrate the concrete and create a protective barrier that reduces the absorption of salts, thereby minimizing potential damage and maintaining the structural integrity of the concrete.

3. Mold and Mildew Resistance

Areas with high humidity or those exposed to moisture are often at risk of mold and mildew growth. These not only discolor the concrete but also create potential health hazards. Applying a penetrating sealer after pressure washing aids in preventing the growth of mold and mildew by providing a moisture-resistant barrier.

4. Reduced Maintenance Costs

The cost of repairing or replacing damaged concrete can be quite significant. By using a penetrating sealer after pressure washing, you can avoid these costs as the sealer extends the life of the concrete, maintains its aesthetic appeal, and prevents damage from various elements.

5. UV Protection

Penetrating sealers also offer protection against UV radiation. UV rays can cause concrete to fade and lose its original color over time. However, a penetrating sealer can help maintain the color of the concrete by providing a barrier against these harmful rays.


In conclusion, sealing concrete with a penetrating sealer after pressure washing is an effective way to ensure the longevity and maintenance of your concrete surfaces. It provides superior protection against multiple forms of damage and helps in reducing overall maintenance costs. Therefore, investing in this method of concrete maintenance and protection is indeed beneficial and cost-effective in the long run.
