Putting down coal-tar-based sealcoating can be a messy job. If you don't believe it, just take a look at the trucks used to hold sealcoating tanks and equipment – they are all probably covered in sealcoat. A job site can get just as dirty if there are accidental spills, or if workers are walking around on cement and concrete pavements with sealcoat still on the bottom of their boots. You are probably going to need to cleanup the sealcoat from the pavement to make your customer happy. Here is how you can clean coal-tar-based sealcoat out of the cracks and crevices in cement and concrete pavements.
You Will Need:
- Brushes (various shapes and sizes)
- Heavy-Duty Degreaser
- Safety Glasses
- Heavy-Duty Rubber Gloves
- Industrial Absorbent Pads
- Polyethylene Bags
Coal tar, heavy-duty degreasers, and the waste you will producing are bad for the skin and eyes. Make sure you have proper gloves and eye protection on before you start a sealcoat cleanup job.
Cleaning Cement and Concrete Pavements
You will need to fill the cracks and crevices with a heavy-duty degreaser and allow it to soak into the sealcoat – figure about 10 to 15 minutes. If you are looking for a environmentally-friendly cleaner to use, try to find one that contain ingredients like citrus terpene mixed with methyl soyate or has aromatic hydrocarbons mixed with ethylene glycol monobutyl ether. After the cleaner has been allowed to sit for a few minutes, take a brush and agitate the sealcoat in the pavement. Scrub the area with a large hand-held brush with medium bristles and then rinse with either a hose or with buckets of water. You should be able to notice right away if the brush got into the cracks deep enough to remove the sealcoat. If there is still some sealcoat remaining in the cracks and crevices, re-soak the spots with the degreaser and let it sit for a few more minutes. You may have to use a much small brush with fine bristles to get into the hardest spots in the pavement - this is way you should always have a box on your truck holding various types and sizes of cleaning brushes. Rinse the area again and check for any sealcoat remnants – you may have to repeat this process a couple of times before you get all the sealcoat out of the cracks and crevices in cement and concrete pavements.
Picking up Cleaning Material
The cleaners you use to clean the mess might be eco-friendly, but the waste you will end up producing will not be environmentally-friendly. Coal-tar-based sealcoating has been shown to affect the environment negatively and you will have to make sure you pick up as much of the used cleaning solution as possible from the pavement and lawn so it doesn't drain into any nearby waterways. You can place industrial absorbent pads and polyethylene bags around the place you are cleaning to control and pick up the waste water and material. Check with your local Environmental Protection Office to find where you can dispose of the absorbent pads.
