Last updated:

When we talk about pristine tiles, we don’t just mean the shiny squares of ceramic or porcelain. Nope, Sir. It’s more than that. The less glamorous grout – that stuff holding your tiles together – plays a pivotal role too. 

When everything’s hunky-dory, you’ve got a floor that gives your neighbor serious house envy. But let grout crack, and suddenly your tiles develop a bad attitude, throwing ‘mood swings’ at your feet. Now, bounced back and forth between professional tile and grout cleaning services would hit the wallet, so prevention, as they say, is better than cure.

Uncovering the Root Causes of Cracked Grout

What sends the grout spiraling from sturdy to cracked? Is it just making its own contribution to the home décor pattern? Nah. It’s more of a distress signal. Whether it’s true if sanded grout is used in joints narrower or if polymer additive was mixed with grout, the focal point lies within the method of execution.

Wrongful Installation: A Major Catalyst of Grout Cracking

Grout cracking is often a result of improper installation, excessive deflection in the substrate, or poor adhesive use. Adding tiles and grout to a not-so-friendly base can set off an ugly reaction, which doesn’t do your floor any favors. 

Too Much Water or Improper Use of Additive

In the grout world, a wee bit too much water or off-kilter use of additive spells disaster. It might seem harmless at first, but as grout dries, pow! You’re dealing with a network of teeny-weeny air pockets. 

Substandard Adhesive Amount

Substandard adhesive amount is another silent destroyer of grout’s glory. It causes defeat from the inside.

Consequences of Inadequate Thinset Coverage on Tile Grout

Used regularly, stuff is bound to fall apart a little. No matter how perfectly you might think your tiles are laid, the grout can begin to crack over time. 

The Role of Cleaning Supplies in Grout Degradation
