Industrial Painting & Coating
Protective coatings applied right after blasting, so your surfaces stay protected for the long haul.
Why Coating Matters
Blasting strips a surface down to bare metal — but that bare metal starts corroding again almost immediately without protection. We apply primer and topcoat systems right after blasting, while the profile is fresh and clean.
Doing both in one mobilization means better adhesion, less downtime, and one crew accountable for the whole job from bare metal to finished coat.
Liquid primer and topcoat is not the only option. For parts that can come to the shop, we also offer powder coating — a dry finish cured in a 30ft oven that lays down more evenly than wet paint and holds up better to chipping and abrasion. Blasting and coating happen under the same roof, so parts never sit around picking up flash rust in between.

How It Works
Coating starts before any paint does. The surface has to be clean, dry, and carrying the right profile, because a coating system is only ever as good as what it was applied to — the most expensive product on the market will still fail early over a poorly prepared surface. That is why we do not treat prep and coating as separate jobs.
Once the profile is right, primer goes on while the metal is still clean, followed by the topcoat system suited to the environment the piece has to survive. Something living outdoors year-round in Georgia weather has different requirements to a part working indoors, and the specification should reflect that rather than defaulting to whatever is on the shelf.
What to Expect on Site
The critical window is between blasting and priming. Bare steel begins flash rusting in hours in this climate, and once that starts the profile is compromised. Running both with one crew on one visit is the practical way to close that gap — it is the main reason we do not hand prep and coating to different outfits.
Cure time depends on the product and the weather. Humidity and temperature both affect how a coating lays down and how long before the piece can be handled or returned to service, so we work that into scheduling instead of promising a turnaround the conditions will not support.
We coat on site and in the shop across Cartersville, Rome, and Marietta.
Common Questions
Can you coat something we blasted ourselves?
Sometimes, but it depends on the condition of the surface when we arrive. If it has flash rusted or picked up contamination it will need re-prepping first, and we will say so rather than coat over a compromised surface.
How long before the piece can go back to service?
It varies with the coating system and the conditions on the day — temperature and humidity both matter. We give you a realistic window for your specific job rather than a stock figure.
What is the difference between this and powder coating?
Liquid systems can be applied on site and to almost any size. Powder coating is cured with heat in our 30ft oven, so the part has to come to the shop, but it produces a harder and more uniform finish.
Do you handle both primer and topcoat?
Yes, as one system. Matching primer and topcoat correctly matters as much as the products themselves.
