Resealing concrete surfaces regularly is essential to protect their appearance and durability. An effective concrete sealant creates a protective barrier, preventing stains, cracks, and fading.
Concrete sealers also slow down deterioration from exposure to sun, chemicals, and other elements. This keeps your concrete looking great longer, saving you money on repairs or replacement.
Finally, routine resealing helps maintain the value of concrete surfaces like patios, driveways, and garage floors when it comes time to sell your property. High-traffic areas from cars or people are the most common areas to reseal.
Knowing which type of concrete seal to get can be difficult. Professionals are skilled at knowing what your goals are and matching your concrete to the right product.
Before you reseal concrete, it’s important to start on a clean surface, so pressure washing services may be necessary for a thorough job.
There are three main categories of concrete sealers that can be used residentially and commercially:
- Penetrating sealers: These absorb into concrete pores for inside-out protection.
- Acrylic sealers: These form a protective coating layer on concrete surfaces.
- Urethane sealers: These offer a high-gloss protective barrier for decorative concrete.
Popular types of sealers include silicone, epoxy, and polyurethane resin. Your project’s best concrete sealer type depends on the location, condition, climate, and desired appearance.
Concrete sealers come in various types and formulations, but generally, they chemically react with the concrete surface to provide a durable, long-lasting barrier against weathering and wear and tear.
Applying a concrete sealer protects in three key ways:
- Waterproofing: Sealers prevent moisture absorption to resist cracks, pitting, and spalling damage.
- Stain-proofing: Sealers block the absorption of oil, grease, food, rust, and other staining agents.
- UV protection: Acrylic resin sealers shield against sun exposure and prevent fading.
Regular reapplication is essential because sealers wear over time. On average, reapplication is recommended every 2–5 years depending on usage levels and climate exposure.
How often concrete needs resealing depends on several factors:
- Type of sealer used: Penetrating, acrylic, and urethane formulations last different amounts of time.
- Amount of foot/vehicle traffic: High traffic speeds up wear and tear.
- UV exposure levels: More sun exposure causes sealers to wear faster.
- Climate: Freeze/thaw cycles and precipitation frequency impact durability.
On average, reapplication every 2–4 years is recommended for residential driveways and garage floors. Commercial facilities may need annual resealing. Always inspect concrete for signs that it needs a fresh protective coat.
Regular maintenance of your concrete and exteriors helps with their functionality and appearance. Read this article for the different ways pressure washing can save money and time in the future.
There are a few signs that suggest your concrete surfaces need sealer reapplication. Awareness of these signs allows you to address issues proactively before more extensive damage occurs.
Cracks can develop over time from natural expansion and contraction of the surface. Temperature changes cause concrete to expand when hot and contract when cold. Tiny cracks form over years of exposure to weather.
While minor cracks are typical, wide or deep cracks indicate a failing sealer that no longer protects the concrete’s integrity. Resealing can prevent further cracking by providing a protective barrier.
Stains from oil, grease, food, chemicals, and other substances are repelled by quality concrete sealers. If you notice new or growing stains coming through the surface, the protective sealer barrier has thinned or worn away in areas.
Reapplication of sealer creates a fresh stain-resistant layer on top of the old sealer and concrete, preventing further issues.
For colored or stained concrete, the rich shades can fade after years of traffic, sun exposure, and weathering. Dulled color indicates the thinning of the sealer layer on top.
By resealing, you restore and protect those vibrant colors from further fading or uneven wear.
Resealing your concrete regularly provides multiple advantages that protect your investment and keep surfaces looking their best.
- Repels stains, moisture damage, and other deterioration issues with fresh sealant
- Fills in hairline cracks, preventing further cracking or damage
- Locked-in stains won’t resurface through a new sealer coat
- Resealing maintains the pristine look and design of colored or stained concrete
Based on typical product warranties of 2–5 years for concrete sealers when appropriately applied, scheduling reapplication every 3–4 years is ideal. That keeps you ahead of problems and maximizes the service life of your concrete surfaces.
By partnering with a quality company, you can be sure your money is well invested in your sealant. Some signs you have a good company include:
- Pre-washing of surfaces before sealing to get rid of surface stains and expose imperfections before sealing
- Attention to detail when sealing cracks to ensure no future problems arise
- Positive reviews and customer ratings from previous jobs
- Transparency of services and prices.
