Where to Use Your White Tile Grout
Kitchen Walls & Backsplashes
Refresh discolored grout lines behind your stove and sink for a clean, bright kitchen look. The waterproof formula stands up to splashes and cooking spills.
Bathroom Floors & Shower Joints
Seal gaps around shower edges, bathtub borders, and bathroom floor tiles to prevent water damage and mold growth. The mildew-proof formula is specifically designed for wet environments.
Floor Tile Gap Repair
Fill cracked or missing grout between floor tiles to restore structural integrity and prevent dirt buildup in open joints.
How to Apply — Step by Step
-
Clean the area: Remove old grout debris, dirt, and grease from the gap using a brush and damp cloth. Allow to dry completely.
-
Prepare the grout: Knead the grout tube gently to ensure smooth, even consistency before application.
-
Apply the grout: Squeeze or spread the grout directly into the tile gap, filling it slightly above the surface.
-
Scrape excess: Use the included scraper to remove excess grout and create a smooth, flush finish along the grout line.
-
Wipe clean: Dampen a sponge or cloth and gently wipe away any residue from the tile surface.
-
Let dry: Allow 2–4 hours for surface drying and 24 hours for full waterproof curing before exposing to water.
Frequently Asked Questions
Can I use this on colored tiles?
Yes — the white grout works on any tile color. It creates a clean, bright grout line that contrasts beautifully with darker tiles and blends seamlessly with white or light-colored tiles.
How long does the repair last?
With proper application and curing, the waterproof seal can last 1–3 years depending on traffic and moisture exposure. High-wear areas may need periodic touch-ups.
Is this grout paint or actual grout?
It's a grout sealer and filler — a paste-like compound that fills gaps and seals joints. It's not a replacement for structural grout in new tile installations, but it's perfect for repairs, touch-ups, and sealing existing grout lines.
Can I use it in a shower?
Yes! The waterproof, mildew-proof formula is designed for wet environments like showers and bathrooms. Allow 24 hours of full curing before water exposure.
How much area does one 100g kit cover?
One 100g kit covers approximately 5–8 linear meters of standard grout lines (3–5mm width), making it suitable for small to medium repair projects.
Does it come with application tools?
Yes — the kit includes a precision scraper tool for clean, even application. No additional tools needed beyond a cleaning brush and damp cloth.
