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
Why choose light gray over white or dark gray?
Light gray is the most versatile grout color — it hides dirt better than white, doesn't show dust like dark gray, and blends naturally with most tile styles. It's the safest choice when you're unsure which color will match best.
Can I use this on both kitchen and bathroom tiles?
Absolutely! The waterproof, mildew-proof formula is designed for both kitchen and bathroom environments. It works on walls, floors, backsplashes, and shower joints.
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. Perfect for repairs, touch-ups, and sealing existing grout lines.
How much area does one 100g kit cover?
One 100g kit covers approximately 5–8 linear meters of standard grout lines (3–5mm width), 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.
