Clean, safe parking gives a good first impression to your customers. A nice, professionally painted parking lot goes a long way towards establishing this. Proper striping and marking create order and organization while visiting your location. However, over time, markings can fade or need replacement. Sometimes, changes are required to improve organization and flow; one of the most effective methods of removing pavement markings is known as scarifying. Find out what it is, how it works, and if it’s the right choice for your parking lot in this blog.
What is Scarifying?
In the field of parking lot striping, scarifying is a mechanical process. During this process, old paint and pavement markings are ground from the surface. When markings need to be removed parking lot managers often opt for scarifying services. This method removes multiple layers of paint and prepares the surface for a brand new set of painted markings.
We’ve covered the basic definition, but let’s get into it. Each step of the scarifying process ensures effective and complete marking removal. It’s straightforward, though it still requires an expert eye and specialized equipment to be done properly.
1. Assessment and Preparation
Evaluating the work to be done is the first step to scarifying markings. Most of this can be completed over the phone and through email. Basic information like surface type (i.e. concrete or asphalt), location, and estimated linear feet for the area to be scarified are collected. I try not to do site visits—on these types of projects, I charge by the linear or square foot, or by the hour. It is important to know what you are dealing with before starting, as using the wrong settings or equipment will cause unnecessary damage.
2. Choosing the Right Equipment
Scarifying machines, or grinders, come in various types and sizes. All equipment will work—it will just take some types longer to complete the task. I would break it into three groups: handheld grinders, walk-behind machines, and ride-on scarifiers. Where each piece of equipment will technically do the job, to do the job quickly and efficiently, a selection must be made. Each piece of equipment will have multiple settings to cut away the perfect amount to remove built-up layers of paint. Rotating cutting wheels grind away at concrete or asphalt to leave behind a paint-free surface. Factors that may influence the selection of a grinder are:
- Thickness of the Paint: Multiple layers of paint require more aggressive machines.
- Type of Pavement: Different techniques are used depending on the parking lot surface. Asphalt is softer than concrete. You’ll get subpar results if you treat the two materials the same when scarifying.
- Size of the Area: Time is money, and efficiency is key to professionalism. For large parking lots with a lot of work to be done, a walk-behind or ride-on scarifier is ideal. Handheld grinders work just fine for small areas.
3. Scarifying the Surface
After considering the job and selecting the equipment, it’s time to work. During the scarifying process, the operator will move the scarifer over the designated area. A paint-free, roughened surface will be left behind. When operating the grinder, control must be maintained to ensure that only the necessary material is removed. The underlying pavement should remain intact.
4. Cleanup and Surface Preparation
With the markings successfully removed, we prepare for the next steps. Debris is swept or vacuumed away. Assessing the clean surface allows the professional to determine if the area is ready for new markings or if more work is required. In some cases, sanding, sealing, or resurfacing may be required before areas that underwent scarifying can be properly repainted. Repainting only after the surface is repaired ensures new markings the best lifespan possible.
Benefits of Scarifying for Parking Lot Marking Removal
There are a few alternatives to scarifying—such as waterblasting, sand blasting, or chemical paint removers—but here are the reasons we recommend it.
- Efficient and Effective: Thick, heavy markings will be quickly removed.
- Prepares Surface for New Striping: New markings will last longer on a clean, smooth surface.
- Improves Aesthetics and Safety: Old, faded markings can confuse drivers and pedestrians in your parking lot. Keep things clean and organized.
- Cost-Effective Solution: Chemical stripping creates hazardous waste, water blasting requires highly specialized equipment, and sandblasting’s messy aftereffects require extensive cleanup. Out of the options available, scarifying is often more cost-efficient and environmentally friendly.
- Durability: The preparation offered by scarifying prepares the surface for new markings to adhere to well.
When to Consider Scarifying for Your Parking Lot
Scarifying might be a new concept if you haven’t dealt with parking lots before. Here are some situations where it is an ideal solution:
- Reconfiguring a Parking Lot: To discourage use of the old layout when choosing to change a parking lot, remove the old markings from sight.
- Faded or Damaged Markings: Faded paint gives off a bad impression. Removing old layers of paint helps improve the visibility and longevity of new ones.
- Compliance with ADA or Local Regulations: If your old layout did not meet requirements, avoid fines and meet regulations by fully removing existing markings when updating the lot.
Parking lot maintenance requires regular upkeep. Outdated and unwanted markings can be taken care of by scarifying. Whether reconfiguring your parking lot layout or refreshing old striping, proper removal techniques ensure a professional and long-lasting result.
