3Pcs Waterproof and Mildew-Resistant Grout | Tile Grout Repair and Touch-Up Pen | Grouting Tools for Kitchens and Bathrooms

Are the grout lines on your kitchen countertop so black you can’t bear to look at them? Are the mold stains on your bathroom floor tiles impossible to scrub off no matter how hard you try? Do the grout lines in your living room trap dirt and grime, making your whole home look worn out? Well, the problem of blackened grout lines can actually be solved with just a pen.

No mixing required, no special tools needed—just gently trace along the grout lines like you’re using a pen. It fills narrow 0.8mm gaps and handles wide 2mm gaps with ease, so you don’t have to worry about a shaky hand causing uneven lines. If you go outside the lines, no problem—just wipe it off and start over. The quick-drying formula dries in seconds and allows for touch-ups.

💧 Waterproof and mold-resistant, with long-lasting protection
Nano-hydrophobic agents form a protective film that withstands prolonged water exposure without peeling off. It withstands kitchen grease, bathroom humidity, and sun and rain on the balcony. With its waterproof and mold-resistant formula, you’ll never have to worry about water pooling in the grout lines and causing mold again.

🎨 Multiple Colors to Choose From, Perfectly Matching Your Tiles
Available in six colors—dark gray, gold, white, beige, silver, and light gray—to easily match tiles of various styles. From creamy white to champagne gold, there’s a shade for everyone.

💰 One pen = savings of over 1,000 yuan
One grout pen can cover 15–20 meters of grout lines, which is more than enough for small-area touch-ups. For just a few dozen yuan, you can do it yourself with results that rival those of a professional.
