The Top Ways to Remove Paint from Concrete

Do you need to remove paint on concrete, but you aren’t sure where to start? There are a number of methods for stripping it. These create a clean surface ready for repainting or concrete repair. Some important factors include:

  • How much surface area you’re dealing with
  • What condition the paint is in
  • Your technical skill level

Here are five methods for removing unwanted paint from commercial concrete:

Elbow Grease

If you have a small spill of wet or badly weathered paint, you may be able to simply scrub it off. You’ll need a scraper, a wire brush, some upper body strength, and plenty of patience.

Sweep the area and apply a cleaning solution. Diluted trisodium phosphate works well here. If you don’t have that or aren’t comfortable working with it, try soap and water. Wet the area down and let it sit for a few minutes before beginning to work. Re-wet the concrete as you go. If nothing else, you may be able to remove enough paint that you’ll only need one round of paint stripper to take off the rest.

Power Washer

If you have a commercial power washer, there is a chance that it can handle this problem. Power washers can be very effective for still-wet paint from spills. It may also be used to remove old, cracked, or peeling paint. However, dry and cured paint in good condition may require more aggressive methods of removal.

Paint Stripper

Paint strippers are very effective and can clear off large areas of paint. However, these chemicals can be dangerous, so follow the instructions carefully.

Start the process with a thorough concrete cleaning. Use a broom or vacuum. If necessary, scrub off sticky residue with soap and water.

Next, get a chemical paint stripper from your local building supply or home improvement company. If you know whether the paint is oil based or water based, use a paint stripper formulated for that. Otherwise, try products intended for oil based paint.

Apply the paint stripper. Make sure that you wear protective gear. Once the stripper has set for enough time (this varies by the brand), scrape up softened paint and scrub the area with a wire brush. If some paint remains, repeat the process.

Scouring Paste

To make a scouring paste, simply mix a chemical paint stripper with something absorbent. Many people use crushed cat litter or powdered clay. Next, apply the paste and wait. Fast acting paint strippers may require 20 minutes to soak in, while slower formulations may need several hours.

Scrape the excess paste off and then scrub the area. The combination of an abrasive with the chemicals should help lift the paint in one or two applications.

Soda Blasting

This is a ‘dry’ form of scouring that blasts the area with chemical powders. Like with paint strippers, this is effective for larger areas. Baking soda is the most commonly used chemical. You’ll need to rent a pot blaster and purchase some coarser soda. Sand blasters cannot handle this job, and household baking soda is too fine to be effective. You should be able to buy the right kind of soda from the same place where you got the pot blaster. Follow the directions carefully, and don’t forget to use a respirator or dust mask while working.

How Does Asphalt Paving Work

No matter if you are a beginner or a seasoned construction worker, knowing the proper method of asphalt paving can make or break your ability to be successful in this industry. No matter if you are starting your own company, work for someone else, or if you simply want to learn the basics of asphalt paving, you should know that the method is often the most important part of the job. That said, the following is a short guide on the basics of asphalt construction.

The 7 Areas of Pavement Construction

If you are searching for the basics of pavement construction, they are as follows:

  1. Site prep: Before you are able to begin paving, you must make sure the site is properly prepared. This can involve the replacement of areas that are extremely damaged, milling, applying of a leveling course, and more. Every site is different. However, you need to make sure each site is properly prepared before you can begin construction.
  2. Demolition and removal of old material: Next, you must demolish and remove any materials and debris that may stand to adversely affect your paving efforts. This can provide the use of bobcats, forklifts, large dump trucks, forklifts, heavy machinery, and more. The purpose of this step is to remove the existing surface, so your site can be prepared to receive the new asphalt.
  3. Grading: The purpose of this step is to make sure the area is prepared for the appropriate water drainage necessary to sustain the new pavement over time. Using various tools and technology (most often, laser transit), this step is done to ensure the new pavement will not be greatly damaged by rain, water, and other watery elements.
  4. Base: One of the most important parts of creating new asphalt pavement is to ensure that the sub-base is laid properly. As we know, having a stable foundation is vital to being able to properly build anything. This is because the sub-base serves as a stable support for new pavement. Additionally, the sub-base is also important because it can help protect the new asphalt from the winter elements.
  5. Binder: Next, the binder is added. This consists of a larger aggregate and oil mixture, which makes it exceptionally strong and durable. In short, the binder is considered to be the strength behind all new asphalt surfaces.
  6. Final surface layer: Once you had added the binder, it is now time to install the top layer of your asphalt surface. This is a smaller aggregate mixed with sand and soil. The combination of the previous material mixed with this layer creates the smooth, shiny, jet black asphalt, which most are accustomed to.
  7. Joints/transitions: Lastly, since most surfaces are connected to things such as driveways, parking lots, and roadways, asphalt construction workers must take the time to smooth the transition spaces between the new and older surfaces. This not only makes everything safer, smoother, and sturdier, but it also makes everything appear more uniform and professional.

Overall, there are various methods of asphalt paving. No matter which method you choose, you must be sure that you are completing each step with the utmost precision and professionalism. Otherwise, the new asphalt will become akin to old asphalt and will thus, will need to be redone by a contractor or company that can.

Why Is Drainage Important for Asphalt Pavements?

If you’re planning on building a parking lot or sidewalk, one of the most important things that you need to consider is drainage. Unfortunately, this is often overlooked because it’s not something you can see when you look at a parking lot. Water is the number one culprit in deteriorating asphalt, but with proper planning, you can avoid water damage and deterioration, and ensure the longevity of your site.

Warning Signs of Poor Drainage

If your parking lot has a weak drainage system, it’s pretty evident not too long after your project is complete. If your site has poor drainage after completion, a few of the warning signs you may experience include:

  • Stagnant water pooling in areas, and running down the lot
  • Evidence of rock, sand, or dusty residue in low spots indicated that the water is breaking down the asphalt
  • Water coming through exterior walls and structures

What happens if your site doesn’t include drainage?

Without proper drainage, the longevity of your site and structure will decrease rapidly. Poor drainage can lead to damaged exterior walls, cars, pedestrians, infect local water resources, and penetrate the asphalt’s surface. As standing water penetrates the asphalt, it gets into the subsoil and weakens the base causing cracks. If you want to ensure that your pavement is durable and longlasting, make sure that your asphalt company incorporates appropriate drainage planning into your project.

Drainage Features for Consideration During Planning

When planning proper drainage for your asphalt paving project, there are a few features that you need to take into consideration for your install. Your asphalt company should be able to provide you with an analysis and assessment of your site and present you with the best drainage options for your particular needs. Here are a few areas of consideration that your asphalt company will address during planning.

Slope

If your site is level and prime for pooling water, your planning should include creating a hill. A slight slope (2% grade) in your parking lot or sidewalk allows the water to flow to the outside and not pool in the middle.

Water Direction

Your drainage system should be designed to direct the water away from the exterior walls and create a path to exit appropriately. You need to make sure that water has a place to go that isn’t in your parking lot!

Asphalt Curbing

Including curbing in your planning and design can help you direct water into grassy areas, by providing a tunnel through the curb line. At the end of the curb line, you’ll have installed a drainage point.

Drains & Inlets

Strategically placing drains and inlets around your site gives water an appropriate place to go. Drains and inlets work well with slopes, directing contaminated water.

Pollution Control

Water coming out of parking lots and sidewalks can pick up a variety of pollutants as it flows through your site. Proper drainage planning includes consideration of where the water’s final destination is. It should be in a place that will not infect the water system and disposed of appropriately.

Planning the construction of a parking lot or sidewalk can be a lot of work, but unless you want to deal with numerous maintenance issues like cracks and breaks, make sure that drainage planning is part of your process before your asphalt pavers show up. Not only will it save you a ton of money in upkeep, but it ensures that your investment is built to last and endure for the longterm.

5 Types of Asphalt Pavement

Did you know that asphalt is the most reused, recycled, and most versatile pavement material? Well, 94% of the 2.6 million American paved roads are made with asphalt. It has been known to be smooth, quiet, safe, and durable.

The pavement structures can be developed in such a way that they can handle any kind of load from passengers to cars and heavy trucks. During asphalt construction, the surface mixes can be customized to reduce splash, absorb noise, and even treat rainwater.

If you are a business owner planning to take on a pavement project, here are five asphalt types that you may want to check before making a decision.

1. Porous Asphalt

The porous asphalt has been there since 1970. It is majorly used in parking lots to allow smooth drainage of rainwater after heavy rainstorms. If storm water isn’t appropriately drained and pools on an asphalt surface, it may cause other defects like potholes, which are dangerous to both pedestrians and motorists.

Porous asphalt prevents potholes and other water-related damages by offering the rainwater a channel to drain. The asphalt companywill place a layer of porous asphalt over a reservoir of the pen graded stone. This way, the water will travel through the pavement, to the stone bed, and eventually infiltrating the soil. When carefully done and maintained, porous asphalt can last over 20 years.

2. Perpetual Pavement

This is a combination of the several layers type of design process and asphalt. From that collaboration, you can tell that they’re long-lasting, smooth, and durable. The process begins by applying a base layer that is base crack-resistant, flexible, and strong enough to handle traffic tension.

The mid-layer offers structure, and the top layer provides that rut-resistant surface to give asphalt the required durability. Installing perpetual pavement is quite straightforward for any experienced asphalt company. It is fast and does not disrupt traffic. If well maintained and given that restorative care, perpetual pavements can last more than 50 years.

3. Quiet Pavement

From its name, quiet pavement is a unique type of asphalt that helps reduce traffic noise. Paving roads with asphalt reduces noise both outside and inside homes and workplaces.

The porous and the open-graded asphalts are popular quiet pavement mixtures as they dissipate the sound energy made by tires. Finely mixed asphalt mixtures can significantly reduce noise as they can decrease contact between the tire and the pavement.

4. Warm-Mix Asphalt

The warm-mix asphalt is made the same way as the hot-mix asphalt only that it is about 50 -100 degrees cooler than the hot-mix asphalt. Reducing asphalt temperature has a number of benefits, including lowering greenhouse gas production during manufacture and mixing, and also reduce fuel consumption.

Other benefits include increased production, improved long-term durability, extended paving season, and the ability to incorporate the reclaimed asphalt pavement.

5. Thin Overlays

Thin overlays reduce pavement distress, lifecycle costs, noise levels, and improves ride quality. Thin asphalt overlays were the most commonly used in preventative maintenance treatments according to a 1999 survey by AASHTO. They provide functional improvements that increase smoothness and safety.

However, it is essential for a business owner to understand that thin overlays aren’t appropriate for all pavements. You may need to carefully examine the existing pavement to determine the functional, structural, and drainage conditions of that pavement.

Why is Parking Lot Striping Important?

If you’re like most people, then you spend a lot of time in parking lots. From going to the grocery store to heading to the mall for four hours on a Saturday, we spent a great deal of time in these areas. But while you park, leave your vehicle, then hop back in for the ride home, you probably don’t really think about the different aspects of parking areas and how they work. From the striping to the flow of traffic, there are many aspects that result in a well-functioning and great looking parking area.

In this post, we’ll discuss parking lot striping and talk about five reasons why it’s important.

Safety

Parking lots can be massive with hundreds of spaces crammed into a little area. With so many people walking to and from their vehicles—not to mention the hundreds of cars leaving and coming in at the same time—staying safe can be a tough task. That’s were parking lot striping comes in. This striping helps to label pedestrian areas in order for drivers to know to stay clear of these locations. In addition, striping on parking lot paving can help to improve the flow of traffic. From angled parking spaces to arrows that label the direction of traffic, this striping helps the parking lot function properly to limit accidents and other complications.

Handicap Access

Another reason why striping on parking lot paving is so important is that it gives proper access to handicapped individuals. Some parking lots don’t clearly label these areas, which could lead to others parking in these reserved spaces. In order to provide access for these handicap individuals, parking lot striping makes it easy. This striping can help drivers and pedestrians clearly see these parking spaces to ensure the right individuals park there.

Appearance

Have you ever noticed a parking lot that was just recently completed or one that was just repainted? If so, then you probably noticed how great it looked. That being said, another benefit of parking lot striping relates to the curb appeal. In fact, this can be a deciding factor for a customer to walk into your store or not. In addition, it’s vital to routinely re-paint your parking lot to give off a great impression and welcome customers into your store.

Guides Traffic

One of the more beneficial purposes of striping is to properly direct traffic. Given how some parking lots can fit hundreds of cars, it’s important to have the right traffic guidance in place—including freshly painted striping that clearly marks parking lot spaces, the direction of traffic, walking paths, and more.

Maximizes Parking Area

Another reason striping is vital for parking lots is because it helps to maximize the parking area. If you have faded striping or no striping at all, this can make it confusing for drivers, which could lead to an ineffective flow of traffic and a lot of wasted space. That being said, it’s best to strategize where to place your parking spaces, then ensure that the striping is done appropriately.

Striping Does it All

From helping businesses get customers in the door to providing safety for those customers, parking lot striping is probably more important than you thought. So the next time you head to the grocery store or bank, take a look at the parking lot striping and think about how important it really is.
