Abrasive blasting is a requirement to prepare the substrate before applying most types of Teflon coating by providing the right “key” for coating and even when not required, surface profiling by blasting improves the properties of all coatings. Think of coating like paint on a wall. If the wall is dusty, oily, or flaking, the paint won’t bond properly. Industrial coatings are no different, just with higher stakes.
Why Surface Preparation Matters
1. Adhesion Is Everything
Coatings do not “stick” just because they are sprayed on. They bond mechanically to the surface profile created during blasting.
Abrasive blasting:
- Removes rust, oxidation, and old coatings
- Strips away grease and contamination
- Creates a microscopic surface profile
That roughened profile gives the coating something to grip onto. Without it, coatings can peel, blister, or delaminate.
2. Prevents Early Failure
If corrosion, scale, or contamination is left behind, it continues reacting under the coating. That can lead to:
- Rust creeping underneath
- Bubbling
- Flaking
- Reduced lifespan
Proper blasting eliminates those hidden weak points before coating begins.
3. Ensures Food & Industrial Compliance
For food manufacturing equipment, surface cleanliness is critical. Contaminants or old degraded coatings can compromise hygiene standards.
Correct surface preparation:
- Removes embedded residues
- Creates a clean base for food-safe coatings
- Helps maintain regulatory compliance
In industries where downtime costs thousands per hour, prevention matters.
4. Extends Component Life
When blasting is done correctly:
- Coatings last longer
- Parts require fewer refurbishments
- Equipment performs more reliably
It is far more cost-effective to prepare properly once than to recoat repeatedly.
5. Different Materials Require Different Preparation
Stainless steel, aluminium, and mild steel all respond differently to blasting media. Using the wrong abrasive or pressure can:
- Damage soft metals
- Leave contamination
- Create incorrect surface profile
Professional surface prep means choosing the right media, pressure, and method for each component.
80% of coating failure is cause by poor surface preparation. We make sure that doesn’t happen.
The Process
- Inspection of component
- Media selection (grit type chosen based on material)
- Controlled abrasive blasting
- Surface profile testing
- Final clean and preparation for coating
