Black Cat FAQs: Crack Sealing
As payment ages, it oxidizes and shrinks causing random cracking throughout the pavement. Cracks lead to potholes. Properly sealing asphalt cracks as they appear can more than double or triple the effective service life of the pavement.
No - only straight-line cracks that are larger than 1/16th of an inch can be sealed. Alligator cracks cannot be sealed.
Alligator cracks means that water has penetrated the subgrade layer of your pavement and is a sign of extreme deterioration. We use GATORPAVE; a premium-grade blacktop resurfacer, especially designed for repair of alligator cracks.
Cracks that appear from too much sealer build up cannot be sealed. Although they appear to be cracks they are not cracks in the structural layers of your pavement. Indentations in the asphalt cannot be sealed.
We will seal the edge cracks as much as possible but because of the lack of surface area on the outside edge some of the sealer will leak out and it can appear to have indentations along the edge for this reason. This will still prevent water from penetrating the base of the asphalt protecting it from further damage.
- Everything must be moved from the driveway or parking lot so that we are able to seal all cracks agreed upon.
- There cannot be any water on the asphalt surface or in the cracks. Crack sealer will not stick to the wet surface and will pull up.
- Do not use a hose or water to clean the surface before we come to do the job.
Black Cat FAQs: Asphalt Sealing
- Sealcoating helps to prevent damage from sunlight oxidation, de-icing chemicals, gas and oil spillage, and other chemical exposure.
- It will extend the life of an asphalt surface by 20 years on average, when used in conjunction with a Preventative Maintenance Plan. All areas should be inspected on an annual basis to correct issues right away.
- It gives your asphalt surface a fresh and well-maintained appearance.
- We recommend every three to five years; depending on the amount of traffic and exposure to chemicals your surface has. Sealing your asphalt too frequently can lead to a buildup of sealer. Cracks that appear from too much sealer build up cannot be sealed. Although not a structural problem it can be an eye sore.
- If you have a newly paved driveway or parking lot, we suggest sealcoating it after the first year from when it was paved. This allows time for the oils from the material that was put down to leave the asphalt and will then allow the sealer to stick and protect your asphalt. If you do not seal the new asphalt after the first year that is ok but the longer you wait to sealcoat it there is a much higher risk of damage occurring.
- Vehicles, equipment, basketball hoops, etc., will need to be moved at least 20-40 feet away from the areas that are being sealed, prior to the agreed upon date. This will improve the efficiency of our crew and help prevent sealer overspray from getting on your belongings. - An inspection will be done during the estimate to determine if any old sealer is present on buildings and or belongings before we begin the work. Areas found will be reviewed by the owner and will not be our responsibility for cleanup.
- Excessive amounts of packed mud and on your driveway or parking lot will need to be removed so that the sealer can stick to the surface. We recommend power washing the areas needed at least 24 -48 hrs prior to our scheduled day. We will go over this at the time of the estimate. Basic cleaning of the surface is included in our fee.
- If there is moss on the asphalt this needs removed and cleaned before we come. Moss will prevent the sealer from sticking to the asphalt. If we need to remove the moss, there will be an additional fee. We will discuss this at the time of the estimate.
- Avoid using chemicals or water hoses on your asphalt surface 24-48 hrs prior to our scheduled date. Standing water, wet surfaces or freshly spilled chemicals will interfere with the sealer adhering to your asphalt. If this occurs, we may need to reschedule your job for a later date.
- If it rains the day of or 24 hrs prior to the scheduled date, we will have to reschedule your job. We do our best to schedule dates with no rain in the forecast; however, the weather can be unpredictable. We apologize for any inconvenience that may cause.
- Do not walk on the sealer until it is dry to touch, and the shine is gone. If you walk on the sealer before it is dry you risk tracking sealer onto other surfaces. If this happens, we can recommend ways to help clean it off; however, it is ultimately your responsibility.
- Do not drive on the newly sealed areas for 24 to 48 hrs to allow for the sealcoat to dry and cure properly. We add products to help the sealcoat dry faster but even with that there is always a chance of there being wet spots. Shaded areas take longer to dry and cure. It is ultimately the owner’s responsibility to control when people drive on the asphalt after the crews are done with the job.
- To avoid leaving tire marks in the sealer, we recommend for the first 2-3 days that you drive on the new sealcoat, that you avoid turning the wheels of your vehicles while sitting still, always be moving when turning the steering wheel. If you do leave marks in the sealer, they will eventually fade and blend in.
- Freshly sealed surfaces can appear stained from water puddles, animal droppings and tire markings. These markings will fade over time and blend into the surrounding sealer.
- We use boards to move along the edge of your driveway or parking lot to help prevent sealer from getting on the grass Boarding the edge of your driveway or parking lot is done to prevent sealer from getting on the grass. Occasionally some sealer may get on the grass, but it will grow and disappear with each cutting. (But if some sealer does get on your grass not need to worry the grass will grow and those areas will be gone after the grass is mowed).
- Rust stains can reappear through the sealer over time if it was present in the original asphalt material when it was laid. These stains are caused by a chemical imbalance in the material. They do not hurt anything other than being an eye sore.
- Sealer is not designed to fill in cracks or divots in the pavement. Sealer is a liquid and made to help protect the surface. It will not smooth out asphalt or make it look like new. Sealer will improve the appearance and extend the life of your pavement.
