How To Tell If Grout Has Gone Bad?
Grout loses its silky white shine over 2-3 years. The water stains, dirt, and other contamination make it discolored soon.
But there are two signs that you shouldn’t ignore. Firstly, check if there’s any mold present on the grout. If there is, there could be mold behind the wall as well. This might be eating away your tile’s lifespan.
No visible mold? Then inspect the texture of the grout. Press your nails with moderate force on them. If it starts to crumble away, it has gone bad for sure.
Why Does Grout Go Bad?
There can be many reasons why grout goes bad. But these are the most common reasons:
Reason 1: Grout Has Gone Old
Grout has a lifespan of over 8-15 years at best. It varies on the condition of your home. It shouldn’t normally have any problems over the first 4- 5 years.
Depending on humidity and contamination, grout starts to go bad. Sometimes molds and mildew grow on the walls, which damages grouts. In those scenarios, removing molds from your walls is important.
Reason 2: Grout wasn’t mixed properly
An important ingredient of the grout is cement. It helps the grout to stabilize. Adding an extra amount of water to the grout mix can ruin the consistency.
It should have a thickness like cake batter. Adding excessive water prevents it from drying and curing properly.
Reason 3: Grout Has Expired
Powdered grouts normally expire after one year. On the other hand, epoxy grouts stay well, as long as they’re not exposed to freezing temperatures.
In your case, it can be that the grout was already bad when it was applied. This is why your grout didn’t last much longer
Reason 4: Grout Is Not Sealed Properly
Tiles and grouts are to be sealed instantly after the installation. Not doing so will allow water and dirt to sink into it. This can lead to failed grout sealing.
If the grout is not sealed properly it gets discolored. Plus it’s also going to fall apart sooner than it was supposed to.
These are the possible reasons for grout going bad.
