FAQs for asphalt sealing projects in Johnstown, CO

If you live in a mild climate, you may only need to seal the surface every three years. If you live in extreme heat or cold, you should seal your driveway every other year to protect it from sun or winter weather damage. Consider the frequency of sealing a driveway when purchasing a home in an area with extreme weather.

Sealing your driveway between spring and fall in optimal warm and dry weather conditions maximizes its protection and extends its lifespan. Moderate temperatures allow the sealant to bond properly with the asphalt surface, ensuring a durable seal. Avoid sealing during extreme heat, cold, rain, or snow, as these conditions can prevent the sealant from curing correctly.

An asphalt filler sealer is a product that fills cracks while simultaneously sealing the asphalt surface, providing comprehensive protection in one application. It's ideal for repairing minor damage and preventing future issues. When selecting the best asphalt filler sealer, consider factors such as drying time, durability, environmental impact, and compatibility with your existing asphalt. Choose a high-quality product that fits your budget and meets your driveway's specific needs to ensure long-lasting results.

Maintaining your coated blacktop is essential for its longevity. Clean your driveway thoroughly twice a year using a stiff broom and a pressure washer to remove dirt, debris, and stains. Reseal the surface when required, every two to three years, to keep it protected. Avoid parking on a newly sealed driveway for at least two weeks. Prevent oil and gas spills, and promptly repair cracks or damage to prevent them from worsening. Removing snow and ice promptly can also protect your asphalt from freeze-thaw damage.

Preventing cracks in your driveway starts with regular maintenance. Clean your driveway thoroughly twice a year to remove debris and identify any budding issues. Seal your driveway every two to three years to protect it from water infiltration, UV damage, and wear from traffic. Promptly repair any small cracks to prevent them from expanding. Avoid parking heavy vehicles on the edges of your driveway and ensure proper drainage to reduce stress on the asphalt or concrete. These proactive steps help maintain the integrity of your driveway and extend its lifespan.

Absolutely. You don't need to be restricted to the standard blacktop asphalt. These days, you can find this material in exciting colors like brown, white, green, brick, terracotta, and more. If you have a color in mind, shop around to find the option that suits your vision for your asphalt driveway.
