5 Commercial Pavement Sandblasting Mistakes

Sandblasting commercial pavements is one of the much-needed pavement services that every commercial property owner must consider from time to time. If you need to clean your pavement quickly and efficiently, or wish to remove the existing pavement paint, sandblasting is one the best ways. However, many people make numerous sandblasting mistakes which can cost them losses and property damages worth dollars. Listed below are some of the common mistakes.

1) Not Being Prepared

Sandblasting is a vigorous process of cleaning pavements. In order to carry out the procedure, one needs to prepare well before getting started. Several mishaps or inconveniences can take place during the sandblasting process. Not wearing safety gears is a serious mistake several workers and novices do. Covering every part of the body and using right eye gears, gloves, aprons, ear and mouth protection, etc. are necessary precautions you must take to remain safe.

2) Not Considering the Aftereffects

Apart from the concerns, one must also be prepared for other problems caused during and after the sandblasting is done. The first thing one needs to do is be prepared for the loud noise. A lot of high-frequency noise is created when the process takes place. It’s best to carry out the process when the commercial lot is unoccupied, or people must wear appropriate gears to cover their ears. Another thing that people on the commercial lot need to be prepared for is dealing with the mess created post the sandblasting process. So before you start, make sure you have enough brooms and other dust-removal materials.

3) Using Wrong Type of Particles

Varied blasting materials are available in the market, and selection of the wrong materials can only ruin your commercial pavement further. For asphalt and concrete pavements, traditional, fine sand is perfect. But make sure there aren’t any small rocks or other debris that can damage your pavement. If you have a pool of calcium deposits, fungus and mold on the pavement or in the crevices, glass bead blasting can be the ideal option for you. Organic blasting materials, such as finely crushed shells or baking soda, are also considered to be some of the best options for cleaning softer surfaces.

4) Using a Small Blaster

When managed on your own or asking the caretaker of your property to sandblast, you won’t have a huge range of products available for commercial sandblasting. And most of the options available are very small. While using a small unit may seem like a good idea, it’s actually better to choose a mid-range blaster. Smaller blasters often require starting and stopping much more frequently. They need to cycle more often than larger blasters, taking up more time. This can be a major concern when you have a large commercial pavement to sandblast.

5) Trying DIY

Sandblasting is a big project, and is best done by professionals. The process can be very dangerous and has the potential to damage your commercial pavement and property. Unless you don’t have in-depth knowledge and hands-on experience, avoid taking up the task of sandblasting in your own hands. Don’t let your gardeners or caretakers of your commercial property do the same if they also lack the expertise. It’s better to hire sandblasting professionals who have complete knowledge about the process and have the specific tools and equipment to carry out the procedure.

Another mistake that most people do is hire an inexperienced worker for their commercial pavement sandblasting project. Hiring a worker without an appropriate level of experience is almost as bad as DIY sandblasting. They may fail to tackle the serious situations and end up making them worse. Therefore, look for proficient sandblasters in your area who provide quality and complete commercial pavement services.

Stamped Concrete Process

Stamped concrete is a paving service that is gaining popularity all over the world. Homeowners aim to create creative and decorative patterns on their concrete pavement, driveways, and walkways to complement the exteriors of their houses. The process of creating stamped concrete involves pouring slab concrete, and then impressing both patterns and textures onto the concrete before it is fully dry. Let us take a look at the detailed, step-by-step stamped concrete process.

  1. Plastic sheeting is used to protect adjacent buildings, landscaping, or other existing slabs before starting the actual process.
  2. The soil is compacted, and the subgrade is prepared for better strength of the concrete layer. A well-compacted subgrade helps prevent drainage and soil erosion under the concrete.
  3. Forms, made from wood, metal or plastic, are attached to stakes to contain the concrete in the desired place.

  4. The concrete mixture is poured in place, and a layer of about four inches thick is created. The most common method for placing concrete is to have the ready-mix truck pull up to the placement area and deposit the concrete from the chute.

  5. The desired color is added to the concrete. Generally, two most common techniques of coloring the concrete are used.
    • Integral Coloring – The liquid or powder color is mixed into the cement mixture before pouring the paste in place.
    • Broadcast Method – A color hardener powder is directly applied to the freshly poured concrete surface. Color hardener then penetrates the top of the concrete slab 1/8″.
  6. When the broadcast method is used to color the concrete mix, it is left for a few minutes to penetrate and completely settle in place.
  7. Once the color is settled, a medium-thick layer of a color release agent is applied to the concrete layer. This is done to prevent the texture or pattern stamping mats from sticking to freshly placed concrete. Stamping mats don’t work without the use of a release agent.
  8. Patterned or textured stamping mats are then applied to the wet concrete mix. The mats are held in place with some amount of pressure for about 2-3 minutes. As concrete starts to dry soon, stamping is done at a faster pace.
  9. Detailing of the patterns are done with the help of hand chisel if necessary.
  10. Concrete is then left to dry for 24 hours or more. During this period, properties of the concrete develop. Concrete becomes denser and less permeable to moisture, and the overall strength and durability increase.
  11. The stamped concrete is washed with water once the concrete is set. The paving is again left to dry for a day completely.
  12. A clear enhancer or sealant is applied on the concrete with the help of a roller, once it is completely dry. This layer helps in enhancing the color or stamped concrete, adds luster to the concrete, and blocks penetration of stains from dirt, chemicals, moisture, etc.

The stamped concrete process needs to be carried out quickly with high precision. This is because concrete dries quickly and fixing any mistakes can be tricky. So, if you make mistakes while stamping the concrete base right, you will be left with an undesired permanent slab that can be difficult and expensive to repair. Eliminate the chances of making any mistakes during your stamped concrete paving by hiring professionals. Experts excelling in various paving services make sure that they finish the process in the limited time window to give you a beautifully stamped driveways and walkways.
