Grout Still Soft

[debo]

Contractor ran out of Prism Ultimate Performance Grout with a small 12" x 14" area left in my pebble shower floor. He finished that area out with Sanded Ceramic Tile Grout in a tube made by the same company, Custom Building Products. After 3 days the area done with the tube grout has not cured. It is still soft to the touch and a little darker than the rest that was done with powder/water mixed grout. He ran water in the shower on day 2 and we showered that night. Is there any hope that it will eventually cure in a few more days if no more water is on it ? What do you suggest ? (p.s. the contractor has been less than knowledgeable all the way around but too late now) Thanks . . .

Hi Deborah, welcome. Dig it out and go get another box of Prism. Sorry but that's what he should have done in the first place. I can't say how long it will take what you have to set. It will likely never match exactly.

I have the tube in my hand and it's actually "Ceramic Tile CAULK". I'm so done with this guy. Even I know that Caulk and Grout are not the same and not intended to be used in the same applications. SO, I'm guessing that area has to be removed ? What are the consequences of leaving it ???

That it's going to take a while to dry and that it may never match exactly. I can't say how long it will take, I've never grouted pebbles with caulk. This guy doesn't sound very knowledgeable. Makes me wonder what else he did wrong.
