What is a Grout Sealer?

Simply put, a grout sealer is a substance applied to the grout between your tiles (or on applicable surfaces) in order to help them withstand staining and resist water absorption. Otherwise, when water is absorbed into the grout, there can be growth of bacteria due to the water source.

Moreover, un-sealed grout can be more prone to staining, which is just plain awful to look at in a kitchen or bathroom, especially in showers and bathtubs.

Types of Grout Sealer

There are two main types of grout sealers available. The first one is Impregnators or Penetrating sealers. This kind of grout sealer is meant to fill up the empty spaces in between your grout, thus blocking debris, oil, dirt, and water from entering.

Moreover, under penetrating sealers comes two sub-types, which are Hydrophobic and Oilophobic.

  • Hydrophobicthis kind of penetrating grout sealer will block water and water based chemicals (e.g. drinks, coffee, tea)
  • Oilophobic – this kind of penetrating grout sealer repels both water and oil. Thus, cooking fat, lard, oils, plus water-based substances will be blocked from entering the grout.

The second main type of grout sealer is referred to as Coatings. Coatings are essentially sealants that are applied on the surface of the grout, thus barricading the grout underneath from dirt, debris, oil, and water.

Two subtypes of coatings are strippable (can be removed easily) and permanent coatings (difficult to remove).

Factors to Consider Before Buying

1. Function

Before buying a grout sealer, you have to look at its other functions aside from being a grout sealer. Of course, the number one priority is being an effective grout sealer, but if you're buying a quart of it, it's better to make sure that it has some other functions, such as acting as a sealant for other surfaces (marble, cement, or stone)

In buying a multi-purpose sealer, you can use it for numerous projects around the home. Moreover, if you buy an outdoor-indoor sealer, you can use your whole quart for more projects inside and outside the home (garage, patio, kitchen, bathrooms).​

2. Effectiveness

I cannot vouch for all grout sealers out there, but in this list, we have the most effective products in the market. What you're going to need to look for in a particular product is of course, its efficiency in sealing surfaces and grout.

How would you know if a product is effective? Well, this product review should help you distinguish the brand names that are most effective. However, effectiveness sometimes depends on the type of surface you have and if you've applied the sealer correctly. 

TIP

In order to maximize the effect of your grout sealer, make sure that you've followed the instructions correctly. However, number of applications can depend on the type of surface or grout that you have, as well as the amount of time between applications.

3. Longevity

Another important factor when choosing a grout sealer is how long it's going to last on your surfaces. It is essential that we select a product that can last up to 3-5 years until a reapplication is needed. Otherwise, we're just wasting money and effort on cheap grout sealers that cannot protect your surfaces for long.​
