If you are a regular reader of our blogs, you probably know by now that sandblasting is the process of forcibly propelling a stream of abrasive material. Whether it be silica or similar, under high pressure to smooth; shape or remove any unwanted debris from a surface. Although we always recommend hiring a professional sandblasting service; there are 3 essential rules that you and your commercial decorators should know about sandblasting.
Choosing the right type of blasting material
Before your sandblaster begins shot blasting, they should ask you what you aim to achieve from their services. This is so that they can decide which type of media will be best suited. Each form of media has different properties and a different hardness which means they will react differently. For example, glass beads are the perfect option if you are looking to give an object a new lease of life. Aluminium Oxide is great for surface preparation due to its sharp and angular shape and steel shot is best if you want to remove any unwanted contaminants.
If you are thinking about hiring an experienced sandblaster, then they should stress to you that the process is going to be timely. Patience is needed in helping you achieve your desired result with no damage. At Markwell Peck, we always recommend hiring professional, experienced sandblasters in Essex as sandblasting can be a very dangerous job. We do not recommend attempting to carry this out on your own; unless you’re equipped with the correct safety equipment and thorough knowledge.
Blasting Tip Size and PSI
It is important to note that when it comes to deciding tip size and PSI, the smaller the tip; the more control you have over the entire process. This is because smaller tips allow fewer media to be released and hit the object, causing less pressure. With regard to PSI, the higher the PSI, the faster it will strip the metal. Although be mindful that a high PSI could also damage the metal dependant on the media you’re using.
