Uniform finishing of an aluminium surface
After removing welds or scratches, it is important to make the surface even and consistent. Uniform finishing is the final grinding step and also your final finish.
Which product suits your workpiece
Use grit 80 to level minor irregularities and grit 120 for a fine finish. Our choice is the 331GR, the 330GR is an affordable alternative. For an even nicer, uniform scratch pattern, finish with the TGR Tex grip disc.
331GR
Ideal for an even, durable finish.
- Aluminium oxide grain with zinc stearate coating
- Greatly reduced clogging
- Tear-resistant film backing
330GR
Affordable alternative for less demanding applications.
- Paper backing (C weight)
- Less tear-resistant than the 331GR
TGR
For an even, uniform scratch pattern after the grip disc.
- Resilient, open structure: does not affect the shape of the workpiece
- Recommended grit: AVFSOFT, also available in other grits
- Washable when the disc clogs

How to create a uniform aluminium surface in 3 steps
Start with grit 80
Level minor irregularities and different scratch patterns with grit 80.
Continue with grit 120
Only move to grit 120 once the scratches from grit 80 are completely gone. This gives you a fine finish.
Finish with the TGR
After grit 120, grind the surface with the TGR Tex grip disc. We recommend grit AVFSOFT. It removes the last grinding marks and gives a uniform scratch pattern over the entire workpiece.
Frequently asked questions about uniform finishing of aluminium
Why is it important to give an aluminium surface a uniform finish?
After removing welds or scratches, you often see different scratch patterns side by side. Uniform finishing makes the surface even and consistent. It is the final grinding step and also your final finish.
Which grit do you use for uniform finishing of aluminium?
Grit 80 is used to level minor irregularities. Grit 120 gives you a fine finish. For an even nicer scratch pattern, finish with the TGR Tex grip disc. We recommend grit AVFSOFT.
Which abrasive disc do you use for uniform finishing of aluminium?
The 331GR film grip disc is our choice. It has an active grinding additive that greatly reduces clogging, a tear-resistant film backing and a long service life. This gives you a consistent, durable finish.
Is there a more affordable disc for uniform finishing of aluminium?
Yes, the 330GR has a paper backing. It is less tear-resistant than the 331GR, but an attractive alternative for less demanding applications.
How do you get a uniform scratch pattern on aluminium?
Only move to a finer grit once the scratches from the previous grit are completely gone. Then finish with the TGR Tex grip disc for a uniform scratch pattern over the entire workpiece.
How do you get a nicer scratch pattern on aluminium?
After grit 120, finish with the TGR Tex grip disc. We recommend grit AVFSOFT. Thanks to its resilient, open structure, you get a uniform, consistent finish without affecting the shape of the workpiece. The TGR is also a grip disc, so you use the same back-up pad as for the 331GR.
