Choosing the Best Grout: A Comprehensive Grout Guide

Finding the best grout for your tile project starts with understanding the different types available. Each one offers unique benefits depending on where and how it’s used.

Cement grout is a classic choice that’s easy to work with and budget-friendly, making it a go-to for DIYers and pros alike. It’s suitable for both indoor and outdoor spaces and works well with a wide variety of tile materials. While it's one of the most accessible grouts to apply, it does require sealing to help prevent stains and damage over time. Keep in mind that cement grout can be sensitive to harsh cleaners or chemicals, so it’s best used in areas with lower exposure to acids and alkalis.

If you want superior performance and long-term durability, epoxy grout delivers. This high-performance option resists stains, cracks, and chemicals, making it ideal for moisture-heavy areas like shower walls, backsplashes, and even commercial kitchens or healthcare settings. While it may take a bit more time and care to install, the payoff is a long-lasting, low-maintenance finish that stands up to tough conditions.

Pre-mixed grout takes the guesswork out of your project by offering a ready-to-use solution that’s perfect for fast, efficient installations. It’s compatible with porcelain, ceramic, stone, glass, and polished tiles, and delivers a smooth, consistent color finish. With built-in resistance to cracking and no need for sealing, pre-mixed grout is a smart choice for both first-time DIYers and seasoned pros. For best results, use with grout joints of at least 1/16 inch.

The best grout for your project often depends on where and how it will be used. Below are a few expert recommendations for your next tile project.

High-performance cement grouts offer a major upgrade over standard options. Designed with faster setting times and enhanced durability, they’re ideal for spaces that need to stand up to heavy foot traffic, like entryways, kitchens, and commercial areas. These grouts are also more resistant to cracking and shrinking, making them a reliable pick for long-term performance in busy environments.

The difference between sanded and unsanded grout comes down to the width of your tile joints. Sanded grout contains fine particles that help prevent shrinkage and cracking in wider joints—typically 1/8 inch or more—making it a great choice for interior floors and large-format tiles. 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.

Moisture-prone areas like bathrooms, kitchens, and laundry rooms demand more from your grout. Choosing specialty formulas designed to resist mold and moisture helps protect your tile installation and reduce long-term maintenance. Here’s what to look for when selecting the best grout for wet environments.

Mold-resistant grouts are specially formulated to help inhibit the growth of mold and mildew in damp spaces. These grouts are ideal for showers, tub surrounds, and other areas where moisture tends to linger. They help maintain cleaner surfaces and cut down on the time spent scrubbing or resealing.

For spaces that see daily splashes or spills—like bathroom floors, kitchen backsplashes, or laundry areas—moisture-resistant grouts are a great option. This type of grout is designed to resist water absorption, which helps prevent damage beneath the surface and extends the life of your tile. Many also don’t require additional sealing.

Grout additives like latex or acrylic improve flexibility and water resistance, while specialized pigments can enhance color retention. Epoxy and other chemical components boost stain and chemical resistance, making certain grout formulas better suited for specific environments. Understanding these ingredients can help you choose the right grout for your project’s needs.

Even the best grout needs the right tools and finishing touches to ensure a professional result. Proper application tools help you work more efficiently, while grout sealers add an extra layer of protection to keep your installation looking great long-term. Here’s how both play a role in a successful project.

Using the right tools makes applying and cleaning grout easier. You’ll need:

Grout Float: Used to press grout firmly into tile joints while spreading it evenly across the surface. Look for a float with a comfortable grip and a flat rubber surface for smooth application.

Grout Sponge: Designed to wipe away excess grout without pulling it from the joints. A damp—not wet—grout sponge is key to cleaning tiles while shaping the joints.

Buckets & Mixing Tools: For cement-based grouts, you’ll need a bucket and mixing tool to achieve the right consistency before application.

Margin Trowel: Handy for scooping grout out of the bucket and applying it to the float.

Sealing your grout is an important step in extending its life and keeping your tile project protected from moisture, stains, and wear. Different grout sealers offer different levels of protection:

Penetrating Sealers: These soak into the grout and provide invisible protection from the inside out. They’re ideal for natural stone and areas exposed to moisture.

Membrane-Forming Sealers: These create a barrier on the surface of the grout, offering excellent protection in dry, stain-prone areas. However, they’re less breathable than penetrating sealers and not ideal for wet environments.

Spray-On Sealers: Great for quick application, especially on large projects. Just be sure to wipe off any excess to avoid a hazy finish on the tile.

Once your tile project is complete, a little regular maintenance goes a long way in keeping your grout looking fresh. Here are a few essentials to keep in your maintenance toolkit:

Grout Cleaner: Use a pH-neutral cleaner specifically designed for grout to remove dirt and buildup without damaging the surface or sealant.

Soft-Bristle Brush: Ideal for scrubbing grout lines gently but effectively, especially in high-traffic or moisture-prone areas.

Grout Sealer (for reapplication): Reapply sealer as needed—typically once a year—to maintain stain and moisture resistance.

Microfiber Cloths: Great for everyday wipe-downs of tile surfaces, helping reduce grime before it settles into grout lines.

Grout Repair Tools: Keep touch-up tools or caulk on hand for small cracks or gaps that may develop over time.

Choosing the best grout isn’t just about color—it’s about performance, protection, and long-term durability. Whether you're working on a simple backsplash or a full-scale renovation, the right grout type, tools, and maintenance routine can make all the difference in how your tile holds up over time.
