The Real Deal on Epoxy Grout Drawbacks and Advantages

We have heard from a wide range of sources that epoxy grout is better for certain types of tile installations. It is also been said that it is costly and difficult to work with. Assuming that all of these claims are true, when should epoxy grout be used, what are the benefits and drawbacks, and what are the keys to working with it?

Read on to learn everything there is to know about Epoxy Grout!

Epoxy Grout

What exactly is Epoxy Grout?

This epoxy material is primarily composed of epoxy resins combined with a filler powder, which chemically react with one another to form the epoxy grout material. This makes it waterproof and nearly stain-proof. Epoxy grout forms a strong seal between the tiles. Its durability makes it an excellent choice for splashbacks, floors, and high-traffic areas.

In what situations can I use epoxy grout?

Epoxy grout is best suited for non-porous tiles such as porcelain or ceramic, which do not allow grout absorption within the tile. This grout should not be used on stone or porous tiles because it may penetrate the tile and damage the surface. Epoxy grout is best suited for indoor tiles and perhaps should not be used outside in general due to discoloration caused by prolonged exposure to sunlight and its UV rays.

How easy or difficult is it to work with Epoxy Grout?

There will be much discussion about the difficulties of working with epoxy grout. Early epoxy products were difficult to work with, but changes in the formulation over time have made epoxy grout much simpler to use these days.

Why should you use Epoxy Grout?

Epoxy grout will not crack, shrink, or discolour easily, making it ideal for use in wet areas such as in shower enclosures. It also has a high resistance to the harsh chemicals found in cleaning products. Due to its non-porous nature, epoxy grout does not require sealing, unlike traditional cement grout. Because of these characteristics, epoxy grout is the only way to go if you want the most durable, efficient way to do tile work.

That sounds good, does not it? Let us go over a few more advantages of epoxy grout, and you will quickly realise why you should choose epoxy grout over traditional grout.


  • Epoxy grout is a long-lasting, chemically resistant, and extremely strong material.
  • Epoxy Grout is stain-resistant, easy to maintain, and cleans up quickly. The best thing about this grout is that it cleans up easily with a damp cloth or wet sponge.
  • Epoxy grout is available in a wide range of colours to give your tile surfaces a seamless appearance.
  • Epoxy grout is non-porous and resists mould and mildew growth. This makes epoxy grout ideal for wet areas such as bathrooms and kitchens.

Sounds too good to be true, does it not? Even though it is extremely good because of its durability, it has some significant disadvantages. So, what exactly are the issues with epoxy grout?


Let us now look at the drawbacks of this Epoxy Grout!


  • Working with epoxy grout is a little more complicated because two or three different materials must be mixed in the proper proportions before application. It is recommended that you hire an experienced tile and care professional for the job.  
  • Using epoxy grout takes longer than using traditional cement grout.
  • The material and installation costs of epoxy grout are also significantly more expensive.
  • Epoxy is a quick-drying grout and to avoid waste, the mixture must be prepared in batches. Keep in mind that once the grout is mixed, you only have a limited amount of time to work with it.
  • Epoxy grout could potentially stains and discolours porous surfaces like unglazed tiles causing picture framing, which can become a major issue.
  • When epoxy grout is exposed to sunlight, it may turn yellow over time.

However, the discoloration and yellowing of epoxy grout being permanent, sometimes during a floor restorative process especially for natural stone, the surface grinding process alone can shave off a tiny layer exposing fresh parts if the epoxy grout.
