Frequently Asked Questions

Is it flexible enough for a tight curved door? +
Yes. The V456S12CU is our top-rated curved seal. Most retail seals use a low-flex R1300 curve, but ours is engineered to an R800 radius. This means it follows tighter curves perfectly without snapping or "popping off" the glass.
How do I get a 100% leak-proof corner? +
For complete protection, we strongly recommend pairing this with our PV29 Threshold Bar. While the V456S12CU seals the bottom, the PV29 covers the vulnerable hinge gaps where most leaks occur.

Curved Shower Seal for 4-6mm Glass Fin 12mm V456S12CU Installation Guide - Simba Anti-Mould Shower Seal

✓ DO’S

  • Direct Press: Fit by pressing directly onto the glass edge to protect the surface.
  • Deep Clean: Remove all UK hard-water limescale before installation.
  • Sharp Tools: Use garden pruners for a clean, professional finish.
  • Daily Rinse: Simply wash away soap suds after your shower.

✕ DON’TS

  • No Sliding: Never slide the seal along the glass; this risks scratching.
  • No Extreme Heat: Avoid water >70°C or hair dryers to prevent warping.
  • No Soapy Water: Do not use lubricants—they accelerate mould growth.
  • No Harsh Chemicals: Avoid bleach or acidic cleaners on the seal.
