1. Why should I have my pavement Seal Coated?
- Besides making your parking lot look much better, sealers protect asphalt from the destructive elements of weather, gas, oil and other chemicals that damage the paved surface.
2. What causes scuff marks in the freshly sealed asphalt?
- Scuffing usually occurs on hot days during the first month after the sealing has been done. This is a temporary thing and will blend back into a smooth looking job after time. The best way to avoid scuffing is to be sure your vehicle is moving before turning the wheels.
- Seal coating is not recommended on parking lots that are heavily fractured. At this point, it would be more beneficial to pave the parking lot. If Funds are not available we can fix the holes as the come along and we can beautify it with parking lot striping until it is time to pave. NO NEED to waste hard earned money.
4. How many coats of sealer should be applied?
- One coat of sealer is more than sufficient for the average home driveway. Two coats of sealer are recommended on most parking lots receiving moderate to heavy traffic. A third coat of sealer is recommended on parking lot entrances and drive lanes where excessive wear occurs due to constant turning and heavy traffic.
5. Can sealer fill cracks in pavement?
- No, sealer will not fill cracks in the pavement. Larger cracks should be sealed with a hot rubber crack sealer prior to sealing.
6. Are all sealers the same?
- This can be a tricky question. First of all, any commercial contractor should be using sealer that meets federal specifications. However, you need to keep in mind that sealer is a water based product. Some contractors will actually cut their sealer with water beyond the manufacturer’s recommendation in order to save money. CPM has been applying Sealer for over twenty years and we do what the manufacture tells us.
7. You sealed my driveway and I can see tire tracks. Is this normal?
- Yes. This is a temporary situation due to the weight of vehicles moving the sand around. We add sand to our sealer to help fill in cracks and to produce an anti-skid surface. Usually, after a couple of weeks, these will blend in and you will not see them.
- We ask that it be closed for a period of 24 hours – total. When seal coating your business, we are able to seal coat it on a Saturday, and you may re-open it Sunday morning.
- We will treat the oil spots with petro seal and Initially, yes sealer will stick . However, even when treated with petro seal (which is a water based product that allows the sealer to “stick” to the oil spot), it will come off once a vehicle turns on the oil spot, or it is driven on a few times. Unfortunately, there is not good way to make oil and water mix.
10. What is the best application squeegee coat or spray coat
- This depends if the asphalt is porous the application should be at least a squeegee coat.
- Crack filling is the best preventative maintenance you can perform on your parking lot. Unfilled cracks fill with moisture, then when the temperatures drop below freezing, the moisture in the cracks freezes and expands in the crack. This causes the crack itself to expand and become wider and longer. Overtime, when left untreated, the crack will turn into many cracks, which then becomes a pothole.
12. How often is crack filling recommended?
- Yearly or every other year! It is best to get on an annual crack filling program. It is normal for new cracks to develop each winter in Ohio, and some existing cracks may need re-filled after the winter.
