Comments Off on The Benefits Of Concrete Sealing

Concrete sealing in Rock Hill offers a range of benefits for concrete surfaces, including durability, appearance, maintenance, safety, and comfort. It protects the concrete against damage, discoloration, and erosion from substances such as oil, fertilizer, salt, and household chemicals.

Unsealed concrete is vulnerable to moisture, leading to structural problems such as bowing walls and sagging floors. This can be dangerous for people and pets.

Protects the Concrete from Moisture

Concrete is a very porous material that quickly absorbs water and moisture. If this moisture isn’t drained correctly, it will cause damage. Moisture can seep into the cracks of untreated concrete, and during freeze-thaw cycles, this frozen liquid expands and destroys the concrete. Additionally, if the concrete remains wet for long periods, it can develop mildew and mold, damaging it.

A penetrating concrete sealer can help stop this from happening by filling the pores of the concrete and preventing moisture from entering the surface.

A durable concrete sealer forms a firm protective layer and is resistant to chemicals and stains. It can last for up to 25–30 years. Depending on the traffic and weather conditions, it may need to be reapplied every 3–6 years. Before resealing, it is recommended to test the surface with a moisture meter. A penetrating sealer can be applied if the meter reads below 4%.

Prevents Stains

Concrete can be stained by gasoline, oil, and other chemicals that seep through the surface. A concrete sealer blocks these oils and makes the concrete more resistant to stains.

A penetrating sealer (also called an impregnating sealer) is a chemical that penetrates deep into the concrete to react with the material, dramatically reducing the surface’s ability to absorb moisture and other foreign materials. This helps prevent staining, freeze-thaw damage, efflorescence, salt attacks, and other problems. Penetrating sealers offer slip protection, leaving surfaces natural, unmodified, and non-slippery.

While paints darken a concrete patio’s appearance and stains permanently apply color to the concrete, clear concrete sealers protect concrete from deterioration while maintaining its natural look. A transparent poly aspartic urethane coating will protect your concrete against water, sun exposure, and other elements while allowing you to enjoy its beautiful look.

Prevents Water Damage

Concrete driveways, sidewalks, and garage floors that aren’t sealed will be damaged over time. The concrete will slowly lose strength as it absorbs rain, snow, and moisture that eventually freezes and expands inside the concrete pores and capillaries. This damage will cause pits, cracks, and spalling. Concrete sealing in Rock Hill prevents this damage by creating a waterproof barrier.

Concrete sealers protect the concrete from de-icing salts and other chemicals used in northern climates to melt ice and salt the roads. These chemicals wreak havoc on concrete by attacking the concrete’s reinforced steel and can cause surface spalling, corrosion, and premature weakness.

A good concrete sealer will last 3-5 years before it needs to be reapplied. When reapplying, the old sealer should be removed entirely before applying a new coat. If the previous coating is flaking, peeling, or delaminating, fix the problem before reapplying. Light sanding may be needed to prepare the surface for a new epoxy, urethane, or acrylic coating coat.

Prevents Mold and Mildew

Mold and mildew thrive in moist environments. Concrete sealers that prevent moisture will help prevent the growth of mold and mildew.

Keeping areas dry and allowing for airflow will also prevent the growth of mold and mildew. Mold and mildew are unsightly and can be harmful to health.

Mold and mildew can be difficult to remove. Often it is hidden on the back of drywall and wallpaper, in cracks, on ceiling tiles, and behind furniture. If not treated promptly, mold can spread throughout a house or building and cause severe damage.

Keeping concrete and masonry surfaces sealed will help prevent mold, mildew, and dirt penetration. Many different types of concrete and masonry sealers are designed for specific projects. Penetrating concrete sealers are typically designed to resist weather, stains, and dirt buildup. In addition, there are concrete sealers with a UV-resistant material that will protect the surface from sun damage. This is especially important for garages and driveways that are used by cars.
