If you’re thinking, “Do I really need to seal my grout?” the answer is a resounding “Yes!”  Not only is it necessary to seal grout, it must also be resealed every year or so.  Don’t worry, sealing grout is an easy job that you can do yourself with ease!


The Importance of Grout Sealer

Grout sealer is necessary for almost all types of grout.  Since grout is basically made from small pieces of sand and cement, it is susceptible to damage from absorbing water and bacteria.  Additionally, unsealed grout is a stain magnet.  Grout sealer protects the grout, making it impervious to water and germs.  A sealed grout system will look and feel great for years, and you won’t have to worry about it collecting mildew or mold.


There is an exception to the grout sealer rule: epoxy grout.  This special style of grout is made of a different, more resilient material.  The caveat? It’s more expensive than standard grout solutions.


How to Choose the Right Grout Sealer for Your Home

The two main types of sealers are penetrating grout sealers and non-penetrating grout sealers.  Determine which sealer is right for you by the type of tile and the location of the tile in your home.


Use Penetrating Grout Sealers If: the tile is located in damp areas of your home, like showers and restroom areas.  This type of sealer uses a water base so that it can permeate the porous grout.  This prevents moisture from staying deep into the grout.  This sealer works best on traditional porcelain and ceramic tiling.


Use Non-Penetrating Grout Sealers If: you are sealing tile in your kitchen.  These sealers, often called membrane-forming sealers, create a resilient coating on the surface of the grout.  Perfect for cleaning up food messes.  This style of grout sealer would not work in a restroom, since it won’t allow water trapped underneath the barrier to evaporate.  Additionally, this style of sealer is preferred for unglazed tiles like natural stone.


Applying the Grout Sealer

Generally speaking, there are three different ways to apply grout sealer.  It can either be painted, rolled, or sprayed on.  While each method has its own benefits and drawbacks, it comes down to personal preference.

  • Painting: this method uses a brush to carefully seal the grout. The issue with the brushing method is that you are working with a less consistent stream of sealer, which means that the sealer may not stick and apply in some areas. It’s an easy fix, though.  All you need to do is go over those areas again with the sealer on a brush.
  • Rolling: this method is commonly preferred over brushing. It’s an easy process, rolling the sealer over the grout and then cleaning excess sealant off the tile surface.
  • Spraying: this method might seem like the easiest and most convenient, however, it could cause you to spend much more time cleaning throughout the whole process. The issue with spraying is that it’s less precise than a brush or roller, which means that you might have to clean off a lot of residue on your tiles after applying the sealant.
