Expert Tips for Partial Concrete Repairs and Grinding for Flatness
Introducing the "Level Grinding Wheel" for use on Flat Surfaces
■ Materials to prepare
grinder, flat polishing grindstone#36 and #80
■ How to use
Make sure the material is fully hardening.
(If it's only half dry, it will be difficult to scrape off, so make sure to dry it thoroughly.)
Use a grinder to scrape it off little by little.
(In the video, a #80 grindstone is used to grind the Repair Resin , and a #16 grinding stone is used for the resin repair material.)
Carefully grind it down so that it is flush with the mating surface.
Once there are no remaining scrapes and it is flat, it is complete.

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.
