Uniform finishing of a steel surface
Uniform finishing is the final grinding step. During cleaning, you remove grinding scratches as preparation. During uniform finishing, you give the entire surface one even scratch pattern as the final finish. This gives you a consistent result, even after painting.
Which product suits your workpiece
Use grit 80 to level minor irregularities and grit 120 for a fine final finish. Our choice is the FCGR: a film grip disc with high cutting power, a long service life and an even finish. For the final finish, the 950GR is a strong choice: its highly wear-resistant zirconia grain produces a finer scratch pattern. The 330GR is the economical alternative for an extra uniform finish.

How to create a uniform steel surface in 3 steps
Choose the right grit
Use grit 80 to level minor irregularities, or grit 120 for a fine final finish.
Work systematically
Grind the entire surface with the same grit, pressure and movement. Do not grind any area longer or harder than others.
Check the scratch pattern
Check that the scratch pattern is the same everywhere. This is your final finish, so touch up where needed.
Frequently asked questions about uniform finishing of steel
Why should you give steel a uniform finish before painting or coating it
Uniform finishing removes small differences in the scratch pattern and minor irregularities left by previous operations. This creates an even surface and prevents visible irregularities and paint defects in the final finish.
Which grit do you use for the final finish of steel
Use grit 80 or 120, depending on the result you want. Grit 80 levels minor irregularities. Grit 120 gives a finer scratch pattern and is the best choice for a fine final finish.
Which abrasive do you use to give a steel surface a uniform finish
Cibo offers several grip discs for this. The FCGR has a film backing that is stronger than paper and more flexible than cloth, with a long service life and an even finish. The 950GR, with its highly wear-resistant zirconia grain, gives a finer scratch pattern for the final finish. The 330GR is flexible, resists clogging and is an economical choice for an even finish.
How do you get an even scratch pattern on steel
Work systematically over the entire surface with the same grit, pressure and grinding movement, and do not grind any area longer or harder than others. Choose grit 80 for minor irregularities or grit 120 for a finer final finish.
What is the difference between cleaning and uniform finishing
You clean the surface right after removing the weld: you remove the deep grinding scratches and prepare the surface for the next step. Read more about cleaning the surface. Uniform finishing is the final grinding step: you give the entire surface one even scratch pattern as the final finish.
