New Grout Without Removing Old Silicone
Regrouting a bathroom is a thankless task: you have to cut the old silicone with a cutter, scrape off the residue, clean, dry, and reapply. Pattex Re-New skips all that. It applies directly over the existing grout, covering it and leaving it white. No removal, no caulking gun, and no tools needed. You can shower again in 6 hours.
SELF-SMOOTHING NOZZLE: a professional finish doesn't depend on your steady hand. The nozzle smooths the bead as you go, and if you're not satisfied, you can wipe it off with paper and reapply immediately.
Why choose Re-New
- ✓ Applies over old grout: saves the slowest and messiest part of the job.
- ✓ No caulking gun or tools: squeeze the tube like a thick marker.
- ✓ Long-lasting mold protection: it doesn't just cover the problem; it delays its return.
- ✓ Correctable: if it doesn't look right, wipe it off with paper and redo it. No rush.
- ✓ Whitens and covers existing sealants, with good adhesion over cured silicone.
- ✓ Ready in 6 hours: do it in the morning and use the shower that same afternoon.
How to apply
- Clean the damaged grout. There's no need to remove the old silicone; just wipe it with a damp cloth. If there's a lot of mold, treat the area with anti-mold spray beforehand.
- Apply Re-New. Shake the container, hold the tube at a 90° angle to the grout, and gently squeeze. Find the right pressure: if too much product comes out, press less.
- You can repeat. Not satisfied? Immediately remove the product with toilet paper and start over. Clean hands and surfaces with water.
- The finish. Run the tube over the grout again without squeezing: the smoother will leave a perfect bead.
- Done. Clean the smoother with paper. You can use the shower again in 6 hours.

When NOT to use Re-New? If the old grout is detached, hollow, or water is leaking behind it, Re-New will not solve the problem: it only renews the appearance and surface. In that case, the silicone must be removed and sealed from scratch with Silicon 5 Universal or Baño Sano.
