Yes, it is possible to paint a freshly sandblasted surface. However, there are a few important steps that need to be taken before painting.
First, the surface should be thoroughly cleaned to remove any dust, debris, or other contaminants that may have been left behind by the sandblasting process.
Second, the surface should be checked for any rust, which should be removed and treated with a rust inhibitor before painting.
Third, the surface should be primed before painting. A quality primer will help the paint adhere better to the surface, and will also help to protect the surface from rust and other forms of corrosion.
Lastly, it is important to wait for the surface to dry completely before applying paint. The paint will not adhere well to a wet surface and it may cause the paint to fail.
It is also important to note that the type of paint used will depend on the surface being painted, the environment it will be exposed to, and the desired durability and appearance.
