How To Pick The Right Grout And Sealant For Your Job


When it comes to creating a new or refreshed bathroom or kitchen, the choice of grout and sealant you choose can either make or break as a finishing touch.

Not only can grout create a beautiful, clean finish to your project – the right product mixed with a professional application can ensure a lifetime of satisfaction.

Tiled Bathroom

Why do we need grout and sealant?

Grout helps keep your new tiles in place and keeps water and debris from getting into your tiles and to the wall itself. In short, grout offers structural integrity and protection.

Sealant, on the other hand, protects your grout from long term wear and tear. Continued exposure to moisture, detergents and temperature changes from the hot and cold taps can dissolve some of the mineral components within the grout. This can then allow microbes to take hold, which in turn accelerates the rate of deterioration, and can lead to a widespread bacteria or mould infestation that goes behind the tile possibly penetrating the wall or floor itself. Once moisture and mould penetrate the wall, the eventuating decay leads to the structural decline of the walls and floors around your wet area.

How do I pick the right grout and sealant?

Grouts and sealants rarely offer a one-size-fits all model, but the good news is that it means you can get the most appropriate and long-lasting product for your project.

Consider the type of traffic a family laundry gets week to week compared to that of a driveway or commercial kitchen. A family laundry may be exposed to some mild detergents and levels of moisture from time to time. Meanwhile, a driveway withstands a huge amount of physical stress on a daily basis, and a commercial kitchen may be exposed to strong detergents several times a day.

What you need to consider before picking your grout and sealant is:

  • What sort of tile am I using? Is it porous?

  • Where will the grout need to be? On a wall, floor or both?

  • What sort of exposure will the area get? Will it be wet all the time, need to withstand strong chemicals, or be more general for family needs?

  • Do you need an expert to help apply the grout and sealant, or can it be done by you?

Now that you’ve narrowed down your needs, you now need to consider some products.
