If your business has an older parking lot, the markings may have faded or the asphalt beneath them may have started to crumble in small areas. If so, you can revitalize your pavement markings by following the three steps below for cleaning and repairing the surface and refreshing the lines.
Step 1: Clean The Surface
Before you begin patching and painting the pavement markings, any dust and debris needs to be cleaned off. This will allow the patch to stick better to any areas needing repair and ensures a smoother paint application. For this step, you will need a push broom and either a pressure washer or garden hose with a spray nozzle.
Use the broom to remove excess dust and large debris, such as sticks or leaves. Go over the area twice to make sure you remove as much as possible. Then, use the pressure washer or spray nozzle to spray the blacktop. Hold the nozzle at an angle so the dust and dirt is pushed away from your project area.
Allow the blacktop to dry completely. Then, go over it one more time with the broom to remove any dirt that remains before going on to the next step.
Step 2: Repair Small Damaged Areas With Cold Patch Asphalt
After cleaning the blacktop's surface, look for any holes that need to be filled in. The simplest way to fill holes is using cold patch asphalt. Along with a bag of the patching material, you will also need a flathead screwdriver, trowel and something to pack the cold patch down with. This could be a thick, heavy metal pole or a store-bought tamper.
Use the screwdriver to remove any loose blacktop around the edges of the hole you will be patching. Eliminating any loose edges gives you a more solid base for the patch to adhere to. Simply stick the flat end of the screwdriver between the blacktop and loose pieces, then pry them off.
After you have removed all of the loose pieces, pour enough of the cold patch into the hole to fill the bottom. Then, use the trowel to press it firmly into the hole. Repeat until you have filled in the hole completely and there is a slight mound above it.
Once the hole is filled in, use your tamper to pack the patch into the hole. Tamp it until the mound is even with the pavement. Then, follow the patch's package directions to determine how long it should set up before moving on to the third step.
Step 3: Refresh The Markings With Matching Oil-based Paint
Now that you have cleaned and repaired the blacktop, it is time to refresh the pavement markings with an oil-based paint that matches the color of the existing lines. Oil-based paint resists moisture, so it will hold up better outside than latex paint. You will also need a roll of painter's tape and a paintbrush.
Use the painter's tape to trace the outline of the markings. Use the existing ones to serve as a guide. Then, paint within those lines and let the first coat dry completely. Apply a second coat and let it dry.
Carefully pull the tape up to avoid cracking the dried paint. Once removed, your markings should have a straight, even line along the outside.
The above patch and touch-up job is meant for small areas of fading and crumbling. If you need a major overhaul of your parking lot, you may want to contact a pavement contractor like Curtis Clean Sweep to find out what needs to be done to make your parking lot's pavement markings look like new.
