Grout age limit advice

[J3TFX]

Please can anyone let me know if the grout would be ok to use if it's been in the open bag for a week or two? I have just finished the boxing in of the pipe work and a few tiles needed to be added after the main tiling was finished. I have enough grout left over and it seems ok but is it like plaster and after a few days it's scrap?
Also a couple of the floor tile's grout has some cracks. I suspect I used to much water in the mix when I did the job. Do I need to remove all the grout from the cracked area which runs around two 300x300 tiles or is it acceptable just to apply more grout over the top and re smooth?
Thanks in advance
Chris.

I've never had a problem using an open bag of grout tbh but maybe someone else can give an informed answer.

As for the cracked grout I would always remove first before adding more so as to give the new grout a decent bed to sit in. Otherwise you may find it will just crack and lift out.

As long as the grout has been stored in a dry environment, you shouldn't have a problem.

I always remove old grout. As Muse said, it gives your new grout a better bed to set.

I had an unopened bag of grout in my shed for twelve years. Wickes brown. Used some of it last year it was fine. Left the opened bag in there and used a the rest aout two months ago. Was no problem at all. It seems to last for ages and ages as long as its dry.

Thanks very much for the quick replies. I have done the job now, so will see how it sets.
