Grout Pen White Tile Grout Paint Pen
This grout pen provides a paint-like finish that recolors grout to a bright white, reducing visible staining without scrubbing. It is suitable for bathrooms, kitchens, and any room with tile surfaces, including walls, backsplashes, and floors. The long-lasting ink covers up to 150 feet of thin 2mm grout, making it a practical choice for small to medium spaces. The fine 5mm tip allows precise application along grout lines, helping maintain a clean, uniform look across tiled areas.
The pen format offers quick, user-friendly application with minimal mess. For larger projects, plan a few sessions and allow each coat to dry as directed. It is particularly handy for refreshes after remodels or to refresh grout in frequently damp areas where mildew is common. This product emphasizes aesthetics and convenience, delivering noticeable whitening with a dry, durable finish.
Grout Pen White Tile Grout Paint Marker (2 Pack)
This two-pack set extends the whitening capability to larger areas or spare touch-up tools. The markers are designed to color and seal grout, offering a cleaner appearance for floors and ceilings with tile. The ink is described as long-lasting, capable of covering approximately 150 feet of 2mm grout lines. The markers are suitable for use in bathrooms, kitchens, and other tiled spaces where white grout helps create a fresh look.
Consider pairing with a dedicated grout cleaner or pre-wash to remove surface grime before applying the colorant. The dual-pack format helps ensure you have additional tips or pens for extended projects, and the waterproof nature supports tile environments that see moisture exposure. While not a substitute for deep cleaning, these markers deliver a noticeable whitening effect with straightforward application.
PentaUSA Tile Grout Repair Kit
The PentaUSA kit blends a premixed, squeezable grout filler with a fast-drying, triple-protection formula. After application, the product cures to a sanded grout appearance, designed to renew and restore grout lines on floors and walls in kitchens, bathrooms, showers, and other tiled areas. The mix aims to prevent dark staining and other issues that commonly occur with worn grout, providing a fresh, consistently colored result. A key benefit is its versatility across different areas of the home, including showers, tubs, pools, and windows, where grout aesthetics are important.
Application is straightforward: apply the premixed grout, smooth to the line, and allow for drying. The triple protection concept emphasizes renewed grout that resists grime and staining. For best results, ensure the substrate is clean and dry before applying, and follow the kit’s instructions for curing times. This option suits homeowners seeking a more substantial grout renewal beyond surface painting.
Red Devil Pre-Mixed Tile Grout Squeeze Tube

It’s best used for grout repairs where color uniformity and adhesion are critical for restoring a clean, uniform look across tiled surfaces.
The squeeze-tube format supports controlled application, reducing waste and helping you maintain clean lines. It’s suitable for small to mid-sized grout repairs and is often paired with a sealing step to maintain brightness. As with any grout product, proper surface preparation improves the final result and longevity.
Grout Pen White Grout Paint (125ml Can)
This larger-grout project option comes in a 125ml can, marketed as a can version of the Grout Pen concept. The product is intended for unsealed grout and should be tested on a small area to ensure bonding. The can format can be advantageous for bigger surfaces, allowing more extensive coverage while delivering a uniform white appearance across grout lines. It is positioned for larger renovations or areas where quicker, broader application is desired compared to pens.
As with any can-based grout paint, preparation matters. Clean the grout lines thoroughly, remove loose debris, and ensure the grout is dry before applying. Follow coat directions for multiple layers if needed, and consider a compatible sealer after curing to extend the whitening effect against moisture and staining. This option balances project scale with a paint-like finish for a more uniform transformation.

Buying Guide: Key Considerations For Whitening Grout
- Grout type and condition: Unsealed vs sealed grout, sanded vs unsanded grout, and the level of staining or mildew will influence whether a pen, paint, or repair kit is best. Unsealed grout often accepts paints and colorants more readily than sealed grout.
- Project scope and coverage: Pens work well for small to mid-sized areas, while larger projects may benefit from can-based paints or premixed fillers. Check product coverage to estimate how many tools you’ll need.
- Durability and maintenance: Look for products labeled waterproof or mildew-resistant, especially for bathrooms and kitchens. Review drying times and whether a sealant is recommended after application.
- Ease of use: Pens and markers are typically straightforward for DIY users, while repair kits can require more steps but offer longer-lasting results. Consider your comfort level with surface prep and curing times.
- Surface compatibility: Confirm the grout depth and tile material. Some products are designed for ceramic and porcelain, others may be suitable for natural stone but require testing on a small area first.
- Avoiding damage: Test on a small, inconspicuous area to ensure the product bonds well and does not lift or discolor adjacent tiles.
- Sealing considerations: After whitening, sealing grout can help maintain brightness and resist stains. Decide if you want a sealant as part of the regimen and choose compatible products.
- Maintenance routine: Even after whitening, routine cleaning with non-abrasive cleaners helps preserve the look. Avoid harsh chemicals that can degrade the coating or pigment over time.
Overall, the best approach to getting grout white again combines proper surface prep, choosing the right whitening method for the project size, and selecting a product that matches your tile type and moisture exposure. Whether you prefer a quick touch-up with a grout pen or a more complete renewal with a repair kit, multiple options are available to achieve a brighter, cleaner grout line across American homes.
