Highly vulnerable
Unsealed grout is highly vulnerable to stains, mould and bacteria. Grout consist of sand and cement which is highly porous and absorbs liquid very easily.
Thus, any liquid which has colour can leave a stain. Once the grout is dry, it is ready to absorb any liquid. Moreover, once a stain is left over the grout, you cannot clean it. The only solution is to remove it and replace. Therefore, it becomes necessary to always seal a grout to make it waterproof and last longer.
To prevent moulds
Grout is highly susceptible to moulds because of high porosity. Once a grout is wet, it is ready for the mould to grow. Mould in grout is impossible to deal with and the only solution left is to remove the grout and install a new grout.
The mould formation takes place inside the grout and starts growing inside it. As a result, the only solution is to treat the affected area with a fungicide. Therefore, to avoid this troublesome task, it is always better to seal the grout.
Extends life
Unsealed grout can wear down faster in comparison to a properly sealed grout. Once you install the tiles, let the grout rest for about 3 days. This not only adds to the appearance of the tile but also boosts its durability.
Saves the money
Installing expensive tiles and investing in beautiful floors or countertops becomes pointless if its appearance is ruined by stained and grimy grout. Unsealed grout needs to be removed and replaced very frequently. Thus, to make the best out of your investment and to save your money, it becomes essential to seal the grout.
