By: Anglianblasting

Stripping or shaping a smooth surface off a foreign material can be very difficult. Specifically, getting a perfect finish on the corners, crannies and nooks is always challenging. It is for this reason that construction experts opt for sandblasting. What does it mean? How can be it used effectively to remove paint? Well, this article offers you all the insights.

What is sandblasting?

Also known as abrasive blasting, sandblasting involves spraying of a surface with small abrasive articles. While the operation is similar to sanding, it is different in that the interaction with the surface occurs at a very high speed.

It can be used in a range of settings including:

  • Preparation of surfaces before painting or coating it.
  • Removal of sand, paint and rust from fabricated surfaces.
  • Edge profiling of machine components.
  • Removal of mould from plastic materials.
  • Roughening of gas turbine engine in preparation for spray coating.
  • Surface texturing to alter the appearance of stamped materials.

The abrasive used is different depending on the surface treatment needed. Some of the common abrasives are:

  • Crushed glass.
  • Plastic.
  • Steel grit.
  • Ceramic grit.
  • Copper slag.
  • Glass bead.
  • Walnut shell.
  • Aluminium oxide

The abrasive used must be selected carefully. This is because they have different textures, shapes, and density. As such, they may not suit a specific purpose depending on these dynamics. Sampling is, therefore, an important part of the sandblasting process. Further, the equipment used for sandblasting is different. They range from:

  • Hand cabinets.
  • Robotic systems.
  • Dedicated automatic high production equipment.

Note that the type of equipment chosen depends on the surface treatment required.

Sandblasting can be categorized into:

  • Wet sandblasting.
  • Dry sandblasting.

Wet blasting is more common than dry blasting. It involves the use of high-powered stream of water mixed with abrasives. This makes the surface rough to ensure that repainting successfully achieved. Dry blasting, on the other hand, utilizes air as opposed to water. It is more dangerous than wet blasting and as such, the authorities must give permission for the method to be used. Indeed, they must confirm that the professionals have the skills on what is sandblasting used for.

Note that you must always cover or remove delicate surfaces before going through the sandblasting process. Still, avoid sandblasting in places where lead paint was utilized. Whereas lead was banned a few decades ago, it is possible that some of the coatings were applied before the ban.
