Best for: Small bathrooms or kitchens with white or light grout lines that need quick brightening. The marker format is ideal for narrow 5mm joints and edge work where scrubbing is impractical. This product claims to paint, recolor, and seal for a cleaner look and can cover up to 150 feet of 2mm grout with a long-lasting ink supply.
Why selected: A fast, precise solution for touch-ups and line-level restoration. The dye-like ink is designed to deliver a bright white finish without bleach, minimizing mess and downtime.

Caution: Achieving a perfect match may require testing a small area first, especially when changing drastically between light and dark tones.

Buying Guide
What kind of grout can be recolored or restored? Most colorants work on cement-based grout (sand-and-portland or epoxy variants). Check if the product specifies compatibility with sanded vs. unsanded grout and epoxy grout for best results.
Which product is best for large areas vs. touch-ups? For large areas, consider TEC Grout Colorant or MAPEI UltraCare Grout Refresh, which cover substantial square footage in one coat. For precise touch-ups along edges or narrow joints, grout pens from Rainbow Chalk Markers Limited excel.
Do you need a sealer with colorant? Some colorants include sealing properties, while others require a separate sealer for moisture resistance. If moisture exposure is high (showers, backsplashes), a product combining color and seal may simplify maintenance.
How to test color match? Apply a small amount on an inconspicuous area first, allow proper curing time per instructions, and compare under typical lighting before full application.
Application tips: Clean the grout thoroughly, dry the area, and follow recommended drying times. For pens, apply evenly in the direction of the grout lines; for liquids or kits, use the included applicator or brush as directed.
