Sandblasting & Painting
Before painting, we remove rust, mill scale and old coatings with pressurised abrasive blasting to achieve Sa 2.5 surface preparation, so the coating applied on top adheres for the long term.
What Is Sandblasting?
Sandblasting is the process of cleaning rust, mill scale, dirt and old coating residue from a metal surface with pressurised abrasive before painting, so the surface is ready to hold the coating. A paint system applied without proper blasting will soon detach from the surface, however good the product, and corrosion will start again.
For surface preparation we follow internationally recognised standards according to the cleanliness level the project requires (e.g. Sa 2.5 — the standard in which almost all visible rust and mill scale is removed, widely used for industrial plants and highly corrosive environments). Depending on the need we use dry blasting or dust-free wet blasting, and on delicate or historic surfaces we prefer low-pressure techniques that do not damage the material.

Frequently Asked Questions
Why is sandblasting necessary?
It makes the paint adhere permanently and keeps corrosion from coming back.
What is the Sa 2.5 standard?
It is a surface preparation standard in which almost all visible rust and mill scale is removed. It is widely used in heavy industrial projects.
