abrasive blasting begins
Related terms: sandblasting begins
The first application of high-pressure cleaning streams to a facade in a process covering most or all of it.
Abrasive blasting begins at the first application of high-pressure streams of water, sand, chemicals, or other matter to a facade to remove soot, dirt, paint, or contaminants. This process can restore a facade to its original color.
This process ends when it has been applied to a majority of the facade and work ceases.
The start is the first cleaning application, while the end requires cessation after the process has covered a majority of the facade. Water, chemicals, and other media remain included alongside sand in this event definition.
