Expert Tips for Partial Concrete Repairs and Grinding for Flatness
 
Introducing the "Level Grinding Wheel" for use on Flat Surfaces

Materials to prepare

Level Grinding Wheel# 36 / # 80
Grinder

How to use

① Make sure that the material is completely hardening.
(If it's half-dried, it's hard to scrape, so dry it well.)

② Shave it little by little with a grinder.
(In the video, when shaving the Repair Resin, # 80 is used for the grindstone and # 36 for the resin repair material.)

③ Carefully scrape so that it is flat with the joint surface.
It is complete when it becomes flat with no uncut parts.
