Best Epoxy Grout: Colored Grout Sealer and Top Brands Compared

Finding the best epoxy grout for your tile project makes the difference between joints that stay clean and tight for decades versus grout that stains, cracks, and needs constant maintenance. Applying a colored grout sealer over standard cement grout is one option, but epoxy grout eliminates the need for sealing altogether. This guide explains where to buy epoxy grout, how grout color sealer products compare to going full epoxy, and which manufacturers make the best grout brand options on the market.

Epoxy grout is tougher than cement-based grout in nearly every measurable way. It resists stains, acids, and heavy cleaning chemicals without absorbing them. For kitchens, commercial floors, and wet showers, epoxy is often the right choice over standard products.

What Makes Epoxy Grout the Best Choice for Demanding Applications

Standard cement grout is porous. Over time, it absorbs moisture, soap residue, mold spores, and food particles. Even with regular sealing, staining in high-use areas is nearly inevitable. The top-rated epoxy grout products change that equation. They cure into a hard, non-porous surface that cleaning products cannot penetrate. Stains that would lock into cement grout simply wipe off epoxy.

The trade-off is workability. Installing epoxy grout is more demanding than cement grout. It sets quickly, requires thorough mixing, and does not tolerate sloppy cleanup. Most professional tile setters will tell you that the first time using an epoxy grout formula is a learning experience. Read the manufacturer instructions completely before opening the containers, and work in small sections. Keeping joints clean of epoxy residue before it hardens is the most important skill to develop.

High-performance epoxy grout options from brands like Laticrete Spectralock, Mapei Kerapoxy, and Custom Building Products Prism work well in both residential and commercial settings. Each uses a two-part system that combines a resin and hardener. The resulting bond is stronger than the tile itself in most cases.

Colored Grout Sealer vs. Epoxy: Which Approach Fits Your Project

A colored grout sealer is a topical product you apply over existing or newly installed cement grout to add color and protection simultaneously. Grout color sealer products from brands like TileLab, Aqua Mix, and Rainbow fill the pores in the grout surface while depositing pigment. They change or refresh the color while reducing staining. This approach costs less upfront and works well for existing tile where full replacement is not practical.

The limitation is durability. A grout color sealer product needs reapplication every two to four years in wet areas and annually in very high-use zones. It does not transform the grout’s porosity the way epoxy does. For a new tile installation where long-term performance matters, choosing the right grout from the start beats applying grout color sealers repeatedly over decades.

For existing tile with stained but structurally sound grout, applying a quality grout color sealer is a practical, cost-effective refresh. For new installs in showers, commercial kitchens, or floors that see heavy foot traffic, use epoxy.

Where to Buy Epoxy Grout

Knowing where to buy epoxy grout depends on your project scale and brand preference. Home improvement stores like Home Depot and Lowe’s carry a limited selection, typically Mapei and Custom Building Products lines. For a broader range of top epoxy grout brands and specialty colors, tile supply distributors and ceramic tile dealers carry more options. Online retailers including Amazon, TileShop, and Floor & Decor ship most major brands directly to your door.

Purchasing epoxy grout supplies from a contractor supply house gives you access to professional-grade products not always found at retail. If you’re buying in volume for a large project, trade pricing through a licensed tile contractor or flooring dealer saves 15 to 25 percent over retail. Always buy your grout in a single lot to ensure consistent color across the entire installation.

Best Grout Brand Picks for Epoxy and Color Products

The best grout brand for epoxy applications comes down to your color requirements, pot life needs, and where you can source materials. Laticrete Spectralock Pro Premium offers one of the widest color palettes and a longer working time than many competitors. Mapei Kerapoxy Design suits decorative applications with its wide range of coordinating colors. Custom Building Products Prism is a hybrid cement-epoxy product that handles more like standard grout but performs closer to full epoxy.

For grout color sealer products specifically, Aqua Mix Sealer’s Choice Gold tinted versions and TileLab Grout & Tile Color Sealer are consistently well-reviewed for coverage and durability. Test any grout color sealer on a small hidden section before committing to the full area.

Next Steps

Decide whether your project warrants full epoxy grout or a grout color sealer based on whether you’re doing new tile work or refreshing existing surfaces. For new installations in wet or high-traffic areas, choose epoxy and source it from a tile distributor for the best color selection. For existing tile, pick a quality colored grout sealer, clean the grout thoroughly first, and apply two coats for complete coverage. If you’re unsure which product suits your specific tile type or substrate, consult a licensed tile installer before purchasing materials.
