Step-by-Step Repair Guide

Step 1: Prepare the Bathtub Surface

Clean Thoroughly

  • Remove old sealant/debris with a razor blade.
  • Wipe the area with rubbing alcohol to eliminate grease and soap residue

Sand Lightly

Step 2: Apply the Silicone Sealant

Load the Caulking Gun

  • Cut the sealant nozzle at a 45° angle for better control.

Fill the Hole

  • Apply steady pressure, moving slowly to avoid air bubbles.
  • Overfill slightly—you’ll smooth it next.

Smooth the Sealant

  • Dip your finger in water and glide it along the sealant for a professional finish.

Step 3: Final Touches

 Remove Tape Immediately

  • Peel off the painter’s tape before the sealant dries.

Let It Cure

  • Wait 24 hours before using the bathtub (check product instructions).

How to Maintain Your Sealed Bathtub

  • Inspect every 6 months for cracks or peeling.
