Epoxy grout: when is it worth using?

Epoxy grout is a type of grout, i.e. a material used to fill gaps and joints between ceramic tiles, stone, or other finishing materials on floors or walls. Epoxy grout differs from traditional cement grout because its main ingredient is epoxy resin.

Advantages of epoxy grout

  1. Durability: One of the main reasons why more and more investors use epoxy grouts is their exceptional durability. Unlike traditional cement grout, which can crumble and fall off, epoxy grout maintains its integrity for a much longer period of time. This means you don’t have to worry about regular repair work or having to completely replace it.
  2. Resistance to damage: Epoxy grouts are highly resistant to mechanical and chemical damage. They are not subject to discoloration, stains or stains, which makes them particularly useful in places exposed to contact with aggressive factors.
  3. Moisture resistance: Epoxy grouts are non-absorbent, which makes them an ideal choice for wet rooms such as bathrooms and kitchens. They perfectly insulate against moisture and steam, which can prevent the formation of fungus and mold.
  4. Easy to keep clean: Thanks to their smooth and non-absorbent surface, epoxy grout is easy to keep clean. They do not attract dirt and do not require tedious washing or specialized cleaning agents.
  5. Strength of joints: Epoxy grouts create more durable and stronger joints between tiles than cement joints. They are ideal for use with large slabs, glass tiles and glass mosaics.

Areas of application of epoxy grouts

Epoxy grouts, thanks to their unique properties, are used in various types of rooms. In addition to specialized public spaces, such as laboratories, swimming pools or restaurant kitchens, they are increasingly installed in single-family homes. They are perfect for bathrooms, garages, boiler rooms, terraces and even swimming pools. However, epoxy grouts are not suitable for use on balconies or terraces. Due to their vapor permeability, they can prevent moisture from evaporating from under the tiles, which ultimately leads to chafing and falling off of the ceramic tiles.

Epoxy grout – installation

Installation of epoxy joints, although different from cement joints, is not complicated and can be done on your own. Applying epoxy grout requires special tools, such as a heavy-duty trowel and hard sponges. You must also strictly follow the manufacturer’s recommendations because the application differs from cement grouts.

Epoxy grout – composition

Epoxy grouts consist of two main components: epoxy paste as a filler and a hardener. Once the two are properly mixed, application time is limited to approximately 30 minutes, so it is important to prepare only small amounts to avoid wasting material.

Removing old grout and replacing epoxy grout

If you need to replace old epoxy grout, this process can be difficult and time-consuming. There are no chemical preparations available on the market that allow for quick removal of damaged epoxy grout. The most common method is mechanical replacement, using an angle grinder or multi-tool. Alternatively, you can use an electric heat gun to soften the joints with high temperature, making them easier to remove.

To sum up, epoxy grouts are an innovative solution with many advantages, such as durability, resistance to damage and moisture, ease of cleaning and strength of joints. They can be used in various types of rooms, although they are not suitable for balconies and terraces. Installation of epoxy joints is simple, although it requires following the manufacturer’s recommendations. When replacing old epoxy grout, it is worth consulting with professionals and choosing the appropriate removal method.
