Storing on used mixed Polyblend #381 Bright White Non-Sanded Grout 1 lb.

Once I mix the grout with water in the container, do I have to use all of it or can I store the remaining mixed grout in the container? If I can store it, how long will it be good?
Asked by: Mikey
comon folks, you can't believe everything you see online. Contrary to those who say you can, once it is mixed with water, you can't "store" the grout for later use. It will harden within 24 hours. Adding water will just give you a wet rock.

Hi, can this be used on slate, stone and glass mosaic tile with 1/8" joints w/o scratching or should I just use sanded Simple Grout?

Asked by: DIYLSB
Never use sanded grout on glass mosaic. Use unsanded.

Does this need sealing?

Asked by: kaybee
I think that is a personal choice. I haven't tried sealing it, but when I remodel my bath I probably will.

Rated 5 out of 5 by from Great product Very easy to mix and apply. When it is dry nice beautiful white tone. Useful to fix missing or broken grout in shower.

Rated 1 out of 5 by from What a joke This stuff wouldn't mix in the tiny cup the powder reduced to half as much when water was added and remained lumpy even though I mixed it for a very long time. The idea that they can put a line on a cup and expect people to fill it to the line while it settles and all the air runs out is a joke. If I had waited for all the air to bubble out and filled it to the line I would have had soup. Poor design and not worth the money for such a tiny amount of grout.

I would say it only covered maybe 5 sq ft. Someone else's review said it covered much much much more. That is not possible. Had to buy the 10lb container to finish my new backsplash.

Rated 5 out of 5 by from This stuff is great Used this after replacing some loose shower tiles. This was my first ever attempt at grouting, this stuff is embarrassingly easy to use and it looks like a pro worked here.
