Is this product suitable for use to repair grout in a shower?

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.

Bought it, came home, opened it and found it was full of hardened chunks due to humidity getting through their lax sealant technique on the container. Terrible quality control. I tried to chop it up and mix it, but I ended up with a grout that was full of 1/8" chunks of hardened mortar. The large chunk in the image couldn't be cut with a diamond blade, so I guess it is strong!

I used this to grout around 4 tiles that I installed under my old vanity, when I removed the old vanity they had not tiled under it. I had some of my original tiles, but I did not have the grout, which I believe was originally called "buff" twenty years ago. I only need a small amount of grout and went to my go to place "Home Depot", to try to match the color. I found the Polyblend in #122 Linen and took it home. I mixed a small mount to check the color and it was almost a perfect match and since the tiles/grout would now be under the vanity (it's on legs) I wasn't really worried. I'm a DIYer, but this was my first time to lay tiles and grout and I must say it looks great.

I grouted over 1000 sq ft with this grout. I'm having a complete grout failure, it is cracking and crumbling in ALL traffic areas after just 4 months. Every day I see grout chunks and dust in new spots. I don't think I have one intact seam left in traffic areas. Interestingly enough, I have a bath grouted with taupe but sanded grout from Polyblend which has not shed a single speck of dust yet despite heavy traffic. I wonder if there was a manufacturing defect in the batch of Bright White I bought.

I followed the directions exactly, and the grout was cracking out from between the tile the day after it dried. It looked just as bad as the old grout I had removed. There was no seal and continued to absorb water after it had dried, and when I contacted the company listed on the container to ask if there was a step I missed that wasn't listed on the container, they continued to state that I must have done something wrong, were argumentative and contradictory, and displayed poor customer service. I actually bought more of the product after the first round failed, in hopes of trying it a second time. I'm a non-confrontational person, but after calling the company to ask for advice on how to get their product to work and receiving the treatment I received, I plan to return all my unused containers. I won't use this product again, and will continue to suggest to others I know in home repair to spend the extra money for a product that works.

Excellent color match between all three products - non sanded powder for tile, non sanded caulking tube for around shower enclosure, sanded for the floor. All three linen colors match each other. The only downside is the color is a little lighter than shown.

I have never grouted tile before and I had a repair job to fix a tile wall blown up by a plumber. This was just the right amount of grout I needed. It mixes easy but you really got to scrape the bottom and sides to make sure you get it all mixed. Finished job looks good.

I had to mix it a whooooole lot more than it said to on the label, which I pretty well figured, but it wouldn't really stay mixed all that long. I waited too long to use it apparently, which was just 24 hours at most, and I had to throw it away and use something else.
