Posts Under Category: Sealcoating
Rose Paving uses water-based sealcoats. Once the sealcoat is applied, it needs to dry, which means the water has to evaporate from it. Temperature and humidity both play a role in the drying process. The lower the temperature, the longer the dry time. The higher the humidity, the longer the dry time.
As the sealcoat is drying it is also starting to cure. Curing is the process of the sealcoat adhering to the asphalt below it. It is actually a chemical reaction between the sealcoat and the asphalt. The tricky part is the curing can only occur when the surface and air temperatures are 50° or above for a period of at least 24 hours. If the temperature drops below 50°, the curing process stops and doesn’t restart, the chemical reaction cannot be reactivated.
Because the drying and curing processes occur from the top down, you can have a surface that has dried and is safe for foot traffic but the curing process has not yet completed or worse been stopped. Sealcoat materials that are dry but did not finish the curing process are prone to color loss (graying), premature wear, and flaking or delamination.
The main purpose of sealcoating is to protect and prolong the life expectancy of the asphalt. Always make sure the sealcoat has at least 24 hours of 50° weather to cure.
This week, the Rose Paving team gathered at Visitation Catholic Church & School to perform infrared asphalt repairs, sealcoating and lot marking to their parking lot. All materials, services and labor were donated.
- 766 square feet of infrared asphalt repair, consisting of 16 heats over two areas
- Lot marking of 20 single bays / 50 linear feet
- 7,259 square feet of sealcoating, applied via squeegee method
Visitation Catholic School, PreK-8th grade, has served the Chicago communities of Englewood and Back of the Yards since 1891, and is staffed by the Dominican Sisters of Sinsinawa, Wisconsin. The Rose Paving team is proud to have helped out Sister Jean and the children of this school make pavement repairs– so their parking surface is safe for everyone!

Due to bidding processes, decision making, and scheduling, it’s important to act on any parking lot repairs sooner rather than later. In the Chicagoland area, the paving season typically ends by mid-November. In warmer climates, it can be extended by a couple months – but really, the weather patterns these days are unpredictable!
If you have liabilities on your pavement or concrete, it’s vital to repair them before winter hits, as the defects could end up worse come Springtime.

Project Scope: Sealcoat and lot mark all the asphalt roads in the development, totaling 376,462 square feet. The asphalt was installed in 2012, and needed to be protected and maintained in order to withstand traffic, weather and general wear and tear. The asphalt had not been previously sealed, so two coats of Liquid Road sealer was applied in 5 mobilizations. Due to the massive size of the development and the cure time of the sealcoat, many mobilizations were needed – this also helped avoid any inconvenience to the homeowners.
Procedure: Liquid Road Pavement sealer was applied, which is a high performance mineral and fiber reinforced asphalt emulsion blended with polymers and special surfactants for superior adhesion, flexibility, and durability. Liquid Road replenishes the binder that is lost through oxidation and weathering, while providing a slip resistant durable surface treatment. Liquid Road’s deep, rich black color gives old, oxidized pavement a “”like new”” surface that melts snow and ice faster, and reduces cleaning and maintenance costs. The first coat was applied with the squeegee method, and the second coat was applied using the spray method. In addition, 4 parking stall markings were replaced using white or yellow highway traffic paint. The project was completed on time and within budget.

- Carefully inspect your pavement on a regular basis for cracks, fading pavement markings, and other signs of failure or liability issues
- Sealcoating a parking lot helps to slow pavement deterioration; for maximum benefit, asphalt should be sealed every 24-36 months
- Sealcoating should only be performed under the proper weather conditions (50°F during sealer application and for 8 hours afterward)
- Traffic should be kept off a newly sealed surface for 24 hours to allow for drying (curing) time
- Proper attention to cracks will prevent problems from spreading and double the life of pavement
- Singular cracks that are between ¼-inch wide and 1-inch are good candidates for crack sealing
- Crack widening or “routing” is strongly suggested in truck areas, but not in cracks that have already been sealed
- Fixing “birdbaths” as soon as they appear will lessen the chance of water seeping through to the base and becoming a pothole
- Catch basin installation can be a possible solution for improper drainage on a parking lot
- All pre-existing problems such as cracking, low spots, poor drainage, and base or sub-base damage should be resolved before resurfacing pavement
- Concrete is especially durable when it is mixed properly and caution is taken during the curing process
- Concrete needs at least 4-7 days to cure, during which time the surface should be constantly wet
- Lot marking using a “straight-in” design (at 90°) allows for the most stalls and accommodates two-way traffic flow
- According to ADA guidelines, all businesses must have the proper amount of handicapped-accessible parking stalls, and required van parking spaces

The following is a “must-have” checklist to get your parking lot fit for summer:
- Walk your parking lot and note cracks that have either widened or formed over the harsh winter months. Cracks that measure 1/4-inch to 1-inch wide are good candidates for crack sealing.
- Consider if your parking lot or parking garage structure needs to be swept of dirt and debris.
- Take note of catch basins throughout your parking lot. Pay special attention to sinking or deterioration which may indicate a problem beneath the surface – such as broken concrete rings or inlet pipes.
- Pinpoint if sealcoat and lot marking has started to fade.
- Assess any damage from snow plows, such as broken curbs, excessive salting, and damage to catch basin lids and surrounding asphalt or concrete.
- Identify areas of standing water on your parking surface, as these are depressions and areas where asphalt and/or concrete may have heaved.
- Determine whether your lot is in need of basic preventative maintenance repairs or structural repairs.
- Basic preventative maintenance repairs include asphalt or concrete patching, catch basin adjustment, sealcoating, crack sealing, lot marking, and infrared asphalt repair.
- Structural repairs include asphalt or concrete reconstruction, resurfacing, or removal and replacement.
- Evaluate your budget for parking lot repairs. Has that figure been approved for maintenance on your property? Don’t delay parking lot repairs – you will end up spending more money on the same services in the second half of the year.
- Speak with a reputable paving contractor regarding any problem areas you’ve noticed on your parking lot. Once determined, communication is key to keeping your parking surface safe, business running smoothly, and customers and tenants happy.

Not all contractors are equipped to tackle a 2 million-sq.-ft. sealcoating job, especially one that lacks a scope of work and where any proposal must negotiate its way among 10 board members and 1,200 homeowners, all of whom feel they have a vested interest in the work.
But those were the obstacles faced by Rose Paving’s Pacific Division at The Oasis, a gated over-55 homeowners association (HOA) community. The community needed maintenance work on its streets. Rose Paving inspected the roads, met the property manager, asked some questions, and eventually was one of three contractors asked to put together a proposal and estimate.
“It was early in the project so there was no scope or direction,” says David Cohen, general manager. “They said ‘do what you would do to our pavements.’ They were clearly looking for someone to come in and tell them what they needed and create a budget for them.”
This winter, for much of the country, has been a record-breaker. Chicago, for example, has measured over 67 inches of snowfall (29 inches above average) and experienced more days of zero-degree or colder temperatures than any other winter season. Meanwhile, other regions continue to zig-zag between warm, spring-like temperatures one day and blizzard conditions the next. As such, it’s safe to say the weather has not only affected our moods, but it has also wreaked havoc on our pavement.
Better weather and brighter days* are coming, however, so we can’t use it as an excuse. Regardless of whether it might still be covered in snow, your pavement should not be buried on your checklist. Now is the perfect time to address asphalt and concrete repairs to prevent the spread of problem areas and to mitigate potential liabilities.
The first step is inspection. Pick a mild day and walk your pavement to assess the damage caused after a long winter of heavy snowfall, freezing temperatures, excess salting/sanding, and snowplow damage. Common problem areas include pavement cracking, heaving, or rutting; potholes; curb and bumper-block damage; oxidized pavement; and faded line striping or other markings. Solutions may include one or more of the following paving repairs:
- Removal and replacement
- Infrared asphalt repair
- Crack sealing
- Seal coating
- Lot marking
- Catch basin adjustment

S.C.A.L.E. Guide Score: The parking lot was classified as a “C-” according to our S.C.A.L.E. Guide, due to general wear and tear, oxidation, and asphalt deterioration.
Duration of Project: The work was completed in three nonconsecutive days. Because the sealcoating product Polymer Modified MasterSeal™ (PMM) by SealMaster was used on this job, the sealcoat application was performed over a two-day period to provide ample cure time, per the application requirements.
Procedure: The project kicked off with asphalt removal and replacement of one deteriorated area. Our night team then crack sealed when the church parking lot was vacant. PMM sealcoat product was applied over a two-day period. Finally, lot marking was completed following day 2 of sealcoat application.
