The sealant should not be allowed to dry on the surface. It works perfectly with marble, porcelain tiles, sanded grout, ceramic tiles, slate, granite, terrazzo, and glazed tiles, to name a few. 

And the best part is that the effect remains for long. It will prevent all forms of stains and slippage. The solution is also weather-proof and will prevent discoloration due to temperature changes.

Grout Sealer Buyer’s Guide

What are your requirements while purchasing a grout cleaner? This is the first question that needs to be answered. Also, there are some other factors that need to be kept in mind before purchasing. You will have to see the application type and the area it can cover. Read on to know more about these variables. 

  1. Application

There are different ways of application when it comes to grout sealers. Some can be sprayed onto the surface, while others can be applied with tubes. There are options that might also need foam brushes for application, and you will have to purchase these brushes separately. 

Now it is on you to decide the kind of application that would best suit you. Look at the area that you need to cover and make a decision accordingly. 

  1. Kind Of Surface

A cement, natural stone, and granite surface will need a non-corrosive formula so that the floor does not get corroded. While on the other hand, tiles can handle a stronger or a more concentrated option.

Also, if you are going to use it near the washbasin or near soaps, then it is best to stick to a non-toxic formula. This will prevent your system from getting harmed. 

  1. Smell

Some products have a strong smell that can cause issues with breathing while you are applying. Ensure that you are already prepared and your nose is covered well. However, the smell generally does not last long, and you can get rid of it soon. 

  1. Time

Some products may be slightly expensive but may last you for more than 5 years easily. The effect stays on and your tiles stay exactly the way they are. While on the other hand, there are products that will last for a year before you have to reapply again. 

Read the description carefully to understand the amount of time that a surface will remain clean and then proceed.

Verdict

Be it a DIY enthusiast or a professional; a good grout sealer should ensure that the entire shower area is free from damage. 

So, please check the description carefully and read the label before buying. Some products work well with water stains, while others only prevent grease marks. Understand your requirements and only then proceed to make a decision. 

Moving on, let us take you through some of our favorites. The Miracle Sealants 511QT6 511 Impregnator is our personal favorite for its amazing properties. On the other hand, the Aqua Mix Sealer’s Choice Gold 30882-4 is a very natural looking product.
