Benefits of Sealing & Finishing Your Concrete

Concrete sealing involves applying a sealer to concrete. A concrete sealer is designed to block concrete pores to reduce the absorption of water and salts or form an impenetrable layer to repel them. Many people skip concrete sealing and finishing to save time and money. Though concrete sealing is not mandatory, it pays off in the long run.

Here are some reasons why you must consider sealing and finishing your concrete.

Enhanced Damage Resistance

Because concrete is porous, dirt and dust particles can easily penetrate the surface. Sealers cover the holes in concrete, thereby preventing dust, dirt, pet urine, food stains, grease, and oil from penetrating the surface. Sealers also lock out moisture and block the sun’s UV rays.

Sealing your concrete is one of the most effective ways to enhance its durability without changing its natural appearance. Building materials experts recommend sealing concrete every 2-5 years.

Inhibits Mold

Concrete is porous, which means moisture can easily penetrate its surface. Undiscovered or ignored moisture is a recipe for disaster. If moisture absorbed by your concrete does not dry up, mold can grow overnight.

Molds produce acids that can degrade concrete, negatively impacting its strength and integrity. Sealing concrete inhibits mold growth and is one of the most cost-effective ways to ensure concrete surfaces look their best and function well for years. A concrete sealer will close pores in your concrete, reducing the absorption of water and salt.

Ease of Maintenance

Sealed and finished concrete surfaces are easier to maintain and clean. A high-quality concrete sealer can block up to 99 percent of surface moisture. It prevents spills and dirt and dust particles from penetrating the surface. This makes maintenance a breeze.

Maintains Concrete’s Color and Natural Appearance

Concrete can become discolored over time. Discolored concrete surfaces look dingy and old, and can become eyesores. Topical and integral sealers are designed to protect concrete from the elements and help maintain their natural appearance and color for years.


The benefits of sealing your concrete far outweigh the costs. Sealing your concrete surfaces can enhance their durability. A quality sealer can help prevent common concrete problems such as cracking and scaling, which means you will spend less time maintaining and repairing your concrete surfaces and more time appreciating their beauty.
