About This Product
The 7Stars Tile Gap Filler is a 100 ml grout repair filler that gives dark, stained and mouldy grout lines an instantly clean white finish. Instead of scraping out old grout and re-laying it, you simply run the nozzle along the seam and let it set — the same job in minutes rather than a weekend.
It is made for exactly the places grout gives up first: bathroom floors and walls, kitchen backsplashes, the seam around a sink or wash basin, shower trays, countertop edges and skirting joints. Once cured it is water resistant and mould-and-mildew resistant, so it holds its colour in wet areas instead of yellowing and going black again in a month.
The cone nozzle is cut to match your grout line — snip near the tip for gaps up to 1 mm, mid-cone for 1–3 mm, and lower for gaps over 3 mm — so one tube handles fine porcelain seams and wide floor-tile joints alike. Mask either side of the line with tape, apply, scrape level with the small stick, peel the tape and the repair is done.

The black lines around my bathroom floor tiles look white again. Took one evening and no plumber.

— Rohit M.Frequently Asked Questions
How do I use the tile gap filler?
Paste masking tape along both sides of the grout line, unscrew the cover and cut the cone tip open, apply the filler into the gap, scrape it level with the small stick, then tear off the tape. The repair is complete once it sets.
Where should I cut the nozzle?
Cut the cone according to your grout line thickness — near the tip for lines up to 1 mm, mid-cone for 1–3 mm, and lower down for lines over 3 mm.
Is it waterproof and mould resistant?
Yes. Once set it is water resistant and mould-and-mildew resistant, which makes it suitable for bathrooms, showers, sinks and kitchen backsplashes.
Where can I use it?
Use it on bathroom and kitchen tile seams, the joint around a wash basin or sink, shower trays, countertop edges, floor tile gaps and skirting joints.
How much does one tube cover?
Each tube holds 100 ml (3.38 fl oz), which is enough to refresh the grout lines of a typical small bathroom or kitchen backsplash area.
