Minnesota Sealcoating Protects Asphalt Pavement

In addition to extending the life of asphalt, crack sealing and sealcoating makes a dramatic improvement to the aesthetics of outdoor areas. The repainting of parking and handicap spaces, signage, and directional arrows completes the process of recreating a fresh and inviting outdoor space. Interested in learning more?

Tips for Applying Sealcoating

  • Apply a minimum of two coats.
  • Minimum 50 degrees temperature is a must and temperature should be rising for a period of not less than 24 hours. Do not apply when temperatures are forecasted to get below the 50-degree mark.
  • Avoid applying if rain is imminent within the same 24 hour period.
  • Once the application of the seal coat is finished, allow it to cure for 24 hours before allowing vehicle traffic back on the surface.

Frequently Asked Asphalt Sealcoating Questions


1. What is asphalt sealcoating?

The process of protecting asphalt-based pavements by applying an extra layer of coating is called sealcoating. It can prevent the asphalt pavements from damage by water, oil or even UV damage. In the long-run, sealcoating can enhance the life of asphalt pavement and reduce maintenance costs.

2. Is it necessary to perform asphalt sealcoating?

Yes, it is. Asphalt can be damaged by excess heat from the sun, or extremely cold water, ice or snow. Oxidation and oil spills can also cause damage to asphalt. Sealcoat protects asphalt from all this by preventing the excess heat, water or oil from penetrating the asphalt, thus saving you from the otherwise extensive repair work. 

3. What is the best time to crack the asphalt seal?

It is important to check the weather before crack sealing. The best time to crack seal is when the temperature of the pavement surface is more than 40 degrees. Usually, during fall and spring, the cracks are not completely open or closed – they are in an ideal position to crack seal. It should be avoided during the rainy season.

4. What is the difference between crack sealing and crack filling?

Both crack sealing and crack filling are effective methods for asphalt maintenance.  Crack filling is a temporary type of fix for surfaces that are less prone to contraction or expansion due to temperature changes. It is cheaper but in the long run, requires frequent maintenance. Crack filling is done using asphalt emulsions, liquid asphalt, and cutbacks. It is mostly used in places where temperature changes are not extreme.  Creak sealing is a costlier and more effective process, which is more durable in the long run. Crack sealing done by experts can last for up to 8 years with little or no maintenance, hence it is called a permanent fix for active cracks. Crack sealing is done using materials like rubberized asphalt, asphalt rubber, self-leveling silicone, and low-modulus rubberized asphalt. These materials cater to surface expansion and contraction in places with extreme temperature changes.

5. What are the benefits of asphalt sealcoating?

Some important benefits are –
  • Sealcoating slows down oxidation, a process that deteriorates asphalt and speeds up the aging of asphalt pavement
  • Improves the visual appearance of the pavements
  • Increases the life of asphalt by preventing penetration and damage from sunlight, water, ice or oil.

6. What is the cost for sealcoating in Minnesota?

Minnesota sealcoating costs can range from $240 to $650. The exact cost depends on various factors like purpose, area, size, shape, number of coats and accessibility.

7. What are the types of asphalt sealers?

There are 4 types of asphalt sealers –
  • Asphalt emulsion sealers – These are environment-friendly sealers. They smell good and are known to preserve air quality. However, if there is an oil spill, the sealers get easily stained.
  • Coal tar sealers – It is weather-resistant and gives a nice shiny finishing that is also durable. Since coal is used in making this type of sealer, it is less healthy especially for those who use the place regularly.
  • Fast dry sealers – These are used for places where there is always traffic movement because they cure quickly – in less than an hour. Mostly used for highways, hospitals, parking lots, these are bit costlier than the other sealers.
  • Acrylic sealers – These are the best and costliest type of sealers, which are UV resistant, have high longevity (about 7 years), and are resistant to change in temperature conditions. These are also environment-friendly. 

8. Is asphalt sealcoating worth the money?

Although some people claim that sealcoating can be done by oneself, it is always better to go for professionals who can do it in the right manner. Sealcoating gives a longer life to your driveways and along with a nice ambiance to the entire place. It also prevents penetration of oil, water, heat, etc… into the asphalt layer and protects asphalt from oxidation. This itself can save you a lot of money on repairs and frequent maintenances.

9. How are deep potholes repaired?

There are several methods to repair potholes – 
  • Throw and roll – in this method, asphaltic materials are placed in the hole and then a heavy vehicle like truck or bulldozer is driven over it. This is a temporary fix and not a very good solution unless there is a dire emergency to do so.
  • Semi-permanent – This is a cost-effective and simple method where first debris and water are removed from the pothole. Once the pothole is clean and trim, you can place the asphalt material inside and tighten the patch with a vibratory plate or roller.
  • Spray-injection – This is similar to the semi-permanent method, the only difference is that we require equipment to blow the debris and water from the pothole and then to spray a coat od binder, after which pothole is filled with the patch material. There is no need to compact the pothole with this method.
  • Edge seal – in this method, we first use throw and roll to fill and compact the pothole. Then we place a ribbon of asphaltic tack material along the edge of the patch. Finally, we can put some sand on the tack material so that vehicle tires don’t track on it. 
  • Full-depth – this is the most common, efficient and complex method. You should always hire professionals to perform this. This technique re-uses the old asphalt by pulverizing it, mixing it with cement and water and then compact it to prepare the base. 

10. What is the most common paint type used for parking lot striping?

The most common and effective paint type is water-based acrylic line striping paint as it is environment-friendly, durable and provide high visibility and brightness. 

11. What is the cost of striping a parking lot?

The average rate of striping is about $4.25 for every 4 inches width. The exact cost depends on many factors like the size of the parking lot, age of the parking lot (new or old), type of paint used, time required for striping, any other areas to be striped, any asphalt maintenance and repair works, transport, etc…
