So I hired a "pro" to do my floors as I just wasn't up to putting down some 1600 feet of tile.
The "pro" has done a fairly good job laying the tile so far. Lines are nice and straight, spacing is pretty spot on, no large height differences between tiles (there are some).
But then he has his helper do the grout work.
Guy goes at the grout (which I think is way too thick a mix) with float in one hand and wet sponge in the other. Never once does he run the float at a diagonal, nor does he run the wet sponge at a diagonal. Won't listen when I suggest that what he's doing is counter to everything I've ever seen or heard.
That said, the grout joints that HE did are low.
Since they left the haze on the floor and I had to clean it up, I decided to do some of the grout work. I applied the grout with the float, ensuring a good fill, then used the float to clean up by running it across the joints at a diagonal, and finally, after waiting the 10 to 15 minutes (recommended on the Mapei package) used the wet sponge to do the first clean up (again, running it on the diagonal).
My grout work looks tons better than the so called "pro". At least to me. And I didn't have nearly the huge "glaze" to clean up afterwards.
Question is: can I regrout over top of the poor job the "pro" did? Or do I need to make them remove what they've done so I can do it correctly...
