Sandblasting and Surface Preparation
What is Sandblasting?
Sandblasting, or abrasive blasting, is an essential process
for cleaning surfaces and preparing them for further treatment. This technique
effectively removes contaminants such as rust, old paint, and other debris from
various materials, including metal, brick, and concrete. Additionally,
sandblasting etches a fine pattern on the surfaces, creating a specific profile
that enhances the adhesion of subsequent coatings. The surface profile,
measured in microns, is determined by assessing the distance between the
highest peaks and the lowest valleys, ensuring optimal preparation for the
coating process.
Why We Sandblast
The primary objective of sandblasting is to meticulously
prepare surfaces for subsequent treatments such as painting and coating. This
process is vital for more than just cleaning; it removes contaminants that
could hinder the bond between the substrate and the coating. Additionally,
sandblasting creates a specific surface profile that increases the surface
area, enhancing the mechanical adhesion of the coating. This precise
preparation is crucial for ensuring the strong adhesion of protective coatings,
which significantly contributes to the durability and longevity of the
coatings. Effective sandblasting prevents premature peeling and flaking,
thereby playing an indispensable role in the preservation and enhancement of
any asset.
How Sandblasting Works
A sandblasting pot requires two things, abrasives or media
and a whole lot of air. Abrasive materials are introduced to a stream of
compressed air and sent down a blast hose before finally being narrowed down
into a nozzle with a smaller opening. At Industrial Services Victoria, the
machines we use are designed to regulate this abrasive force with precision. We
utilize a variety of media, surprisingly not one of which is sand these include
garnet, steel grit, and glass bead, in different sizes to achieve the specific
profile needed for each project. We talked about needing a whole lot of air sandblasting
requires substantial air flow; fortunately, our robust 400cfm compressor is
well-equipped to support this demanding process.
The Importance of Quality Sandblasting
Poorly executed sandblasting can lead to a range of problems — from uneven surfaces that lead to poor coating adhesion, to overblasting which can weaken the structural integrity of the material. Our expertise ensures that sandblasting is done correctly, maintaining the balance between thorough cleaning and preserving the strength of the substrate.
