Shower Grout Sealer Buyer’s Guide

Now that we have spoken about the features and the pros and cons of the 7 top grout sealers, we hope it will help you decide better. But we understand that you still might have some doubts lingering in your mind. 

Knowing about the features is not enough, and there are a few more factors that you need to take into consideration when deciding to buy one. And in this section, we are going to take a look at some of these factors. 

Let’s see what they are!

  1. Surface

When deciding which product to go for, it is very crucial that you first inspect the surface that you are going to use it on. In case you are working on a big project, we recommend that you opt for a gallon-size sealer.

How big of an area a pack of sealer can cover is clearly mentioned on the packages, and it is advisable that you read carefully before buying. To give you an estimate, a standard grout sealer should cover somewhere around 1000 ft to 4000 feet for every gallon of solvent. 

  1. Resistance To Oil And Water

While choosing an option, it is smart to go for one that is oil or water-resistant, or both. It is a rare combination, but if you are thorough with your research, you will surely find a good one. 

If you are planning to use the grout sealer in the bathroom, where there is regular use of water, you should buy one that is completely water-resistant. On the other hand, if your goal is to provide protective layering to your tabletop or kitchen countertop, oil-resistant formulas are preferable. 

Simply put, depending on the place where you use the sealant, you should opt for one that serves the purpose. 

  1. Longevity

What good is a sealer if it is not long-lasting? Well, re-application is always possible, but that becomes costly and time-consuming. 

Go for one which is durable! We have seen that the non-penetrating sealers tend to relatively last a longer time span when compared to the penetrating formulas. However, penetrating solvents come with a range of benefits that you might not want to miss out on. 

To find the ideal one, you will have to find a good balance. Jot down your requirements, and read through the descriptions of all the products mentioned earlier to see which one will be the perfect fit.

  1. Grout Color

Depending on your aesthetics and décor, you can either opt for a sealer that provides an invisible look or one that has a hint of color. If you are not a great fan of your existing grout color, this is a great chance to get the color changed. 

But if you have a colored grout line that you like, simply choose a transparent coat that only adds sheen to the lines. The major aim here is to not change the color but make the existing one look more shiny and attractive.
