Have you heard about sandblasting? It is a process where fine particles with high velocity are propelled to a surface. Sandblasting removes foreign materials or rough edges thus producing a clean and a smooth surface. In most cases, sand is the most commonly used material in the sandblasting process. However, the dust created by sand may cause a lung disease known as silicosis. In this case, other materials are being used instead of sand. Small and uniform particles such as steel grit, walnut shells, coconut shells, and powdered abrasives will work well. When sandblasting, you require protective wear and proper ventilation to avoid the dangers of inhaling the dust.
Sandblasting can be done on various surfaces
Concrete: In some cases, the property owners may want to remove parking lines and reconfigure them. In this case, sandblasting can effectively remove old paints and produces a clean surface that is easier to work with.
Wood: Sometimes, wood has several layers of paint that are peeling off. Therefore, sandblasting will be very useful if you want to repair the surface.
Brick: Sandblasting can be used to achieve a clean surface on painted and dirty bricks.
Cast Iron: Peeling and chipping paints can be removed through sandblasting process. This process produces a clean surface that makes repainting much easier.
Automobiles: Rust may build up over time on the surfaces of automobiles. Therefore, sandblasting is used in garages to prepare the surface for painting.
Types of sandblasting
Water-driven: this is ideal for concrete and brick surfaces. It cools the surface to which sandblasting is applied, hence reducing further deterioration of the surface.
Air-driven: it is suited for metal surfaces as it prevents water intrusion and buildup of moisture.
Costs of sandblasting
The prices vary considerably depending on the scope of the project. For small home setups, the sandblasting is relatively inexpensive. On the other hand, this process is quite expensive for large-scale projects, especially in industrial environments.
Applications of sandblasting
There are various uses of sandblasting, including:
– Removal of scale, rust, or paints from the components
– Surface preparation before painting
– Roughening of gas turbine engine surfaces before thermal spraying
– Providing a clean and smooth surface on the consumer products
– Removing mold flash from the plastic surfaces
Things needed for sandblasting
This process requires a lot of precaution since there is the risk of inhaling the dust. Therefore, sandblasting should be done in a controlled room that has appropriate ventilation. Moreover, the person performing the process should have protective gear. Also, there should be an alternative air supply to allow successful completion of the project.
What are the tools needed for sandblasting? The equipment used in the process consists of blaster nozzle, abrasive and an air compressor. Sometimes, the collector needs to collect excess dust that results from the sandblasting process.
In conclusion, sandblasting is a process that uses fine particles to clean the surface. This process can be used on various surfaces that include wood, brick, concrete, and cast iron. The fine particles are propelled to surface from a high-velocity nozzle. The sandblasting cost varies depending on the magnitude of the project.
