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
andrust from fabricated surfaces.
- Edge profiling of machine components.
- Removal of
mouldfrom plastic materials.
- Roughening of
gasturbine 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.
- Steel grit.
- Ceramic grit.
- Copper slag.
- Glass bead.
- Walnut shell.

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:

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.

- The surface. Some surfaces may not withstand the high pressure involved in the sandblasting process. It is important to engage a person with skills in the area so that they can make an evaluation and advice on the best way of stripping the paint.

- Alternatively, try to remove the paint in a part of a surface using sandblasting to determine whether damages will occur in the process. Hold the equipment closer to and further from the surface and evaluate the results.
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.
