    A Guide to Sandblasting: Ensuring Top Quality Floors

    The floor of a facility requires regular upkeep to maintain the safety and well-being of employees. Aside from preventing slips, trips and falls, a well-maintained floor helps a business’ bottom line. It improves the appearance of the workplace and leaves a good impression on customers, investors and visitors.

    A surface might need treatment such as a fresh coat of paint or finishing. Before anything is applied, surface preparation is required to ensure that the application lasts long and is of high quality.

    There are several technologies used by professionals to clean the surface of a property before it is deep cleaned or painted. A commonly used method is sandblasting.

    Defining Sandblasting

    Sandblasting, or abrasive blasting is a surface preparation technique in which granular abrasives are applied to surfaces at high pressures to remove corrosives, paint, rust or other substances prior to finishing or treatment. The friction of the abrasive passing over the surface scours and cleans the surface when placed under high pressure.

    Sandblasting can be done in a variety of surfaces: bricks, cast iron, concrete and wood are common surfaces where the technique is applied.

    Why Consider Sandblasting

    Sandblasting is a safer and more efficient alternative for removing contaminants, oil, paint and rust, resulting in smooth, shining material. This is a quicker and more effective technique compared to cleaning methods that can be labour-intensive and require the on-site storage of chemicals.

    Besides removing contaminants, oil, paint and rust, the sandblasting process creates a surface that is ready to accept a fresh coat of paint, finish or other coatings. This is because abrasive blasting removes the thin outer layer of a material, leaving a smooth, bare surface.

    Sandblasting is safe and environmentally friendly, as it does not use chemicals that are hazardous when inhaled or when it comes into contact with skin and eyes. Cleaning after the process is also as easy as using a broom, damp rag or a vacuum.

    How Sandblasting Works

    First, identify the type of material to be cleaned. This will help you determine the equipment you need for the job: an air nozzle, hopper or a sandblasting gun. Even though the name suggests that sand is used for the abrasive, you can utilise powdery abrasive materials and fine pieces of silicon for the process.

    The next step is to prepare the work area. Cover everything that does not need sandblasting to ensure that nothing is damaged while you are sandblasting.

    The sandblasting process begins by directing the sandblaster over the material. An air compressor fuels the machine, allowing the abrasive materials to reach the high speeds required for the process to be effective. Sandblasting becomes more intense as the pressure increases, so be aware of the pressure levels. Too much pressure can cause damage to the material.

    Remember to clean up to ensure the long life of your equipment and prevent damage on the blasted material. Since blaster machines use compressed air, use an air dryer to remove moisture that causes rust and corrosion on the equipment.

    Sandblasting removes a variety of contaminants, is safe for the employees and the environment, and is cost-effective. Consider this technique to ensure that your facility floors are cleaned and ready for a fresh coat of paint or other treatments.
