To make the video we used:
1- Skeletime Thor Strong – Rigid backing pad. Code ABX.0148.20
2- Resin support with obvious undulations and then filled.
3 – We used an 8 mm orbital sander.
4- We used a 40 grit ceramic abrasive.
Advantages:
We obtained a perfectly flat and homogeneous surface without scratches from manual abrasive, without effort, without dust, without overheating of the surface and halving the processing times.
How to use it: Max 6000 rpm.
No pressure with large horizontal, vertical and crossed movements.
Divide the areas one square meter at a time and then unify at the end.
Always use the control light at each processing stage.
