Why is Grouting Your Bathroom/Shower Tile Essential?
Grouting your tile is crucial to optimize its overall integrity. Grout will help prevent damages on your tiles caused by the subtle expansion and contraction of the house. In addition, bathroom grout will also help prevent moisture from seeping in between the tiles. Water that manages to leak into the tile will slowly degrade the substrate underneath.
That said, the grout itself is not impervious to long-term water damage. One of the most common issues surrounding bathroom grout is mold and mildew buildup, leading to the grout cracking over time. Cement-based grout is the most susceptible to this problem as it is porous and not waterproof. This steady deterioration is the main reason why grout maintenance is crucial.
Signs that You Need to Reapply Grout
Some telltale and some not-so-subtle signs that you should start thinking about re-grouting your bathroom. Below are signs that you should look out for and act upon asap to prevent further costlier damage to your bathroom.
Grout Damage Such as Cracks and Holes
This one is pretty much the most prevalent reason to re-apply grout to your tiles. While it is true that grout can last for decades (with proper maintenance), some factors you cannot prevent. Impacts onto the floor, heavy foot traffic, or earthquakes can leave your grout in a relatively lousy shape sooner than expected.
A big reason to re-grout your tiles is if you notice cracks and holes. Keep in mind that the high moisture levels of bathrooms make it a hotbed for mold and mildew. What better place for this mold to thrive than in the crevices of the floor. It is imperative to re-apply grout to damaged sections to prevent further issues from arising in the near future.
Mold and Mildew Buildup
The second primary reason to re-grout is if there is a severe mold and mildew buildup. If you notice molds around the tiles, this is another good indication that the grout is damaged. This mold problem is also unpleasant to look at and gives your bathroom an unsanitary appearance.
The discoloration of the grout can severely hamper the overall aesthetics you are going for – especially if you incorporate white tiles. In addition, if you utilize cement grout in the bathroom, you are most likely to encounter mold and mildew problems. Re-grouting is often the best course of action for this issue, but you can also try using mold removers first. If the mold returns, then re-applying grout is the only solution left.
Steps to Take Before Re-Grouting Your Bathroom Tile
Before you start chipping away at the old tile grout, you must first check if re-grouting will be the only issue you need to address. Has the mold and mildew spread throughout under the tiles? Has the water damaged the substrate underneath?
You check the integrity of the substrate underneath by tapping on the tile. Does it generate a hollow sound? If yes, then it is most likely that the substrate has eroded underneath, and you have an enormous task ahead of you other than just replacing the grout.

How to Clean Super Hard-to-Remove Stains?

A better alternative to the harsh liquid bleach is the milder oxygen-type powdered bleach, but it is equally effective in removing stains. The last option is to use chlorine-based bleach, which is quite a powerful solution, and extra care is required when handling it. Make sure to apply only a tiny fraction of chlorine bleach directly to the grout and avoid touching the tile at all costs.
