How to perfectly grout floor tiles

100% not how to grout a floor Dude your tips are absolute ass

Meticulously done, however not practical for larger projects ...

No idea what its doing. If it was a professional tiler would go broke in a month & be months behind on all jobs.

No.

Now do that in my house which is tiled end to end 3500 sq.

lol...not happening...some one, someone show how its done.

This is not the proper way. The grout needs to be smashed in

This looks like epoxy grout or something like it.

That’s not good for real, it won’t hold for long even not few months
