Over 13 years of operations we have continued to expand our facilities to now include two blast chambers.
TUFF Coatings Australia use abrasive blasting as the initial step in preparing steel surface’s for protective coating systems.
It is used to remove failing coating systems, foreign particles and contaminants that can cause oxidation (rusting).
Poor preparation will prevent adhesion of the first coat to the steel and all contaminants must be removed entirely.
What is Abrasive Blasting
Abrasive blasting is when garnet, grit or steel shot is shot onto a metal surface using compressed air.
The impact of the high speed particles cut away mill scale, rust or contaminants leaving a clean surface.
This leaves small indentations and these are referred to as the ‘key or surface profile’.
TUFF Coatings use a premium grade garnet to achieve the best quality blast results for our clients. Known for its natural hardness, durability and abrasive characteristics, GMA Premium Garnet meets all occupational health and safety requirements.
We work closely with our supplier to remain up to date with technology and techniques to deliver cost effective, contamination free substrates.
Different Classes of Blasting
There are four classes of abrasive blasting and these refer to the cleanliness, contaminant, and colour.
A full break down of these standards can be found in AS 1627 – Surface Preparation Standard and our trained staff can make recommendations on a suitable class for your project.
Surface Contaminants
When Tuff Coatings prepare steel surfaces for a protective coating system, it is critical we remove all contamination. Common forms of contaminants are mill scale, rust and oils, grease fat and perspiration and old protective coating systems.
Surface Preparation during and after Manufacturing
Coating systems are usually the last step in the manufacturing stage and a quality coating finish will add value to your structure, equipment or DIY project.
To assist us in achieving a flawless coatings system defects, welds, burrs, sharp edges and lamination should be ground and filled before being abrasive blasted. Failure to prepare and remove harmful deposits will result in the breakdown of the protective coating system.
