Choosing the "best" tile grout depends entirely on your project's specific needs, such as moisture exposure, joint width, and your skill level. The top industry-standard options cater to different application types, ranging from durable epoxy to high-performance cement.
Jim Whitfield, manager of Technical Services at Mapei told industry professionals, “Because epoxy grout is so tough, it wears extremely well. It doesn't wear down over time and become a tile gutter—like cement grout can—where all the dirt and liquid and junk collects.” Epoxy grout is a reactive grout.
Some may use mechanical brushes to scrub grout and remove tough stains. From there, professional cleaners may use a wet vacuum to extract dirty water and cleaning residue to dry the area, completing the job with a grout sealer to protect against future stains.
When choosing the best tile grout, the right brand depends heavily on whether you are prioritizing water resistance, stain resistance, or ease of installation. For premium quality and professional results, Laticrete, Mapei, and The Tile Doctor (Starlike) are the top-rated brands across the industry.
Epoxy grout: the modern performer
This type of grout is perfect for kitchens, bathrooms, and commercial spaces where spills and moisture are frequent. Pros: Highly durable, stain-resistant, easy to clean, long-lasting.
The "best" quality grout depends on your project, but epoxy grout is widely considered the highest-quality, most durable option for long-term performance. It is waterproof, highly stain-resistant, and chemically durable, making it ideal for moisture-heavy areas like showers and kitchens.
The short answer is no; you cannot simply smear new grout directly over old grout. Because grout is a porous mixture that needs a certain depth to bond, new grout will not stick to the old surface and will crack, flake, and fall out within a few weeks.
The most common types of grout are epoxy, sanded and unsanded. Epoxy grout is made of resins, silica fillers, pigments and hardener. Sanded and unsanded grouts are cementitious grouts.
One of the most frequent grouting mistakes is improper mixing and application. Grout is a precise material, and getting this step right is crucial for its strength and adhesion. Incorrect Water-to-Grout Ratio: Adding too much or too little water can significantly weaken the grout.

If you're a die-hard DIYer, using Dawn dish soap alone can be a safer option for mild cleaning. Dilute a small amount of Dawn in warm water, scrub the grout with a soft brush, and rinse thoroughly. However, this method is less effective for tackling stubborn stains or deep-seated grime.
Just a few more important points: As the grout can absorb the soap as well as a stain, do not clean with oil or wax based cleaners (Murphy's Oil soap, Pine Sol, etc.). These products will leave a waxy or oily film in the grout. Even good alkaline cleaners, if not properly rinsed, will leave a sticky soap film.
Epoxy grout is widely regarded as the best choice for bathrooms and showers due to its outstanding water resistance and strength. Made from epoxy resins and a filler powder, epoxy grout forms a highly durable bond that withstands moisture, stains, and chemicals.
Let the grout set for 15 to 30 minutes and then begin gently wiping off the excess grout with a clean, damp sponge.
Whether your grout should be lighter or darker than your tile depends entirely on the design style, room size, and maintenance effort you prefer. There is no single "right" answer, but each choice achieves a very different look:
Achieving a flawless grout job comes down to proper preparation, exact mixing ratios, and impeccable timing. The most critical mistakes to avoid include: using the wrong grout type for your joint size, over-watering the mixture, and wiping the tiles down too early.

Properly installed and maintained grout lasts 8 to 15 years. However, its lifespan depends heavily on the environment and the material:
Sanded vs.
Unsanded grout, on the other hand, has a smoother texture that's perfect for narrower joints and vertical applications like shower walls, backsplashes, or delicate tile surfaces that could scratch.
As a leading grout product, Mapei Ultracolor Plus FA Grout offers stain resistance and a wide range of colors to choose from. Its fine aggregate ensures a smooth finish for any project.
No, you cannot simply apply a new layer of grout directly over existing grout. Because grout is porous and thin layers cannot bond to a cured, dirty surface, the new grout will crack, crumble, and flake out almost immediately.
No, you do not have to remove all of the old grout down to the base. You only need to remove enough of it to create a deep, solid groove for the new grout to adhere to.
Builders often skip sealing grout to cut costs, save time, and avoid returning to the job site. Additionally, many modern polymer-modified grouts are stain-resistant, and sealing un-cured grout can trap moisture. Some installers even use it as an upsell or exclude it because sealing can leave a hazy film on certain tiles.
Yes, epoxy grout is absolutely worth it if you prioritize long-term durability and low maintenance, especially in wet or high-traffic areas. While it costs about 2 to 5 times more than traditional cement grout and requires professional installation, it is completely waterproof, stain-proof, and never needs sealing.
