The shelf life of grout once opened is typically 6 months, but this will vary depending on the brand and how it is stored.
The presence of small, hard lumps or clumping means the grout may have started to mix with water vapor. Clumps or lumps mean the grout is bad or is going bad. But if the grout is powdery, like a bag of fresh flour, it is probably perfectly fine.
Grout has a shelf life of about one year from day of manufacture if it's unopened and store correctly. Once it's opened it may be OK to use for several weeks or so. Again, it depends on how it's stored. Grout can be lump free for years and still be bad. Lumps are not the only symptom of bad grout or any cement product.
Unopened Containers: Typically last up to one year from the date of manufacture. Opened Containers: Best used within six months, provided the lid is tightly sealed after each use.
There are a number of factors that can cause cracks and issues in the grout. But if cared for properly, grout can last for up to twenty years.

Visual Signs
Look for physical growth in the above areas. If you notice black, blue, green, or pink growth appearing in water-prone areas (most commonly your grout), it's a sure sign you have mold issues. Mold will also grow under tiles, weakening their hold and lifting them.
Start by sprinkling baking soda liberally along the grout lines. Use a brush to ensure that most of the baking soda covers the dirt and grime thoroughly. Then use a sprinkler bottle to sprinkle cleaning vinegar over the baking soda while taking special care to dampen the powder along the entire grout line.
ANSWER - It is possible to grout over existing grout if there is enough depth to do so. 1/8 inch depth may or may not be adequate depending on the type of grout used. A latex modified grout may work, but you have to properly clean the existing grout to ensure the new grout adequately bonds.
The spaces between the tile are filled with grout which can degrade over time if not treated with care.
If your old grout is cement based, re-grouting might be necessary, especially if the grout was not sealed properly at the time of installation. Cement grout is porous and prone to absorbing moisture and dirt that can cause it to break down and deteriorate faster than other types of grout.
The best answer, in a word, is money. It costs more time and material to seal grout and there is little or no perceived benefit (until, of course, the grout gets stained or starts to crack). A superior product would cost more to purchase and install, again for no perceived benefit over the less costly unsealed grout.
If your grout lines have become dingy, dirty, or stained, then cleaning them is a better alternative than re-grouting. In this article, we'll help you determine when re-grouting might be needed versus when grout cleaning will do the trick.
Check the color and condition in some of the higher-traffic areas of the room. If you notice any chipping or cracking in the grout, it won't respond well to cleaning and will most likely just break apart if you try to clean it with any kind of physical force.

You don't have to remove all of your old grout to apply the new grout. The new grout can be applied right over the top of the existing grout. You will need a grout removal tool, which is a small tool with a sharp blade capable of chipping away the grout.
CEMENT POLYMER GROUT has a shelf life of 12 months when stored in normal dry conditions. Joints should be free from efflorescence, laitance, dirt and other loose material. Remove thoroughly by fry brushing.
Before you decide to regrout, evaluate the state of the existing grout. If it's severely damaged, crumbling, or has mold, it may be necessary to remove it entirely.
