Got a dingy, stained, or worn-out bathtub? No need to replace it—refinishing your bathtub is a cheaper, easier DIY fix that restores its shine! This step-by-step guide by The Trade Table will walk you through how to refinish a bathtub like a pro and make it look brand new!
✔ Screwdriver (to remove hardware)
✔ Firm brush / scouring pads
✔ Tack cloth (for dust removal)
✔ Paint roller & foam brushes
✔ Abrasive cleaner (removes grime & soap scum)
✔ 400-grit wet/dry sandpaper (for surface prep)
✔ Drop cloths & painter’s tape (protect surrounding areas)
✔ Bathtub refinishing kit (includes primer, epoxy resin, & hardener)
✔ Caulk & caulk remover
Pro Tip: Check your refinishing kit’s instructions carefully! Some steps may vary by brand.
Shut off the water supply to your tub.
Remove cover plates, drain plugs, and spouts.
Set aside all hardware in a safe spot for reinstallation.
A clean surface is crucial for the refinishing process!
Remove old caulk with a blade & chemical remover.
Scrub the tub thoroughly with an abrasive cleaner.
For tough stains, repeat the process 2-3 times.
Dry the tub completely before moving to the next step.
💡 Tip: Use a plastic putty knife to scrape off stubborn soap scum.
Tape off walls, tiles, and surrounding areas with painter’s tape.
Cover floors & fixtures with drop cloths to avoid spills.
Most refinishing kits include etching powder to remove the tub’s original glaze.
Mix with water and scrub with an abrasive pad.
Rinse thoroughly to remove residue.
💡 Why? If the old glaze isn’t removed, the new coating won’t stick properly!
Use 400-grit wet/dry sandpaper to roughen the surface.
Sand every inch of the tub for maximum adhesion.
Rinse and dry completely before moving on.
💡 Pro Tip: Use a tack cloth to wipe away any remaining dust.
Some refinishing kits include a primer—if yours does, apply it with a roller.
Let the primer dry completely before moving to the epoxy coating.
💡 Reminder: DO NOT use regular paint primer! Only use the one provided in your refinishing kit.
Mix the hardener & epoxy resin (per your kit’s instructions).
Use a roller for large areas & a foam brush for edges.
Work quickly! The mixture will start to harden after a short time.
💡 Pro Tip: Start from the bottom of the tub and work your way up to avoid streaks.
Apply at least 2 coats for a smooth, durable finish.
Some kits require up to 4 coats—check your product’s instructions.
Let the tub dry & cure for 2-3 days before using.
💡 Tip: Some epoxy coatings require waiting 1-2 hours between coats, while others need to be applied back-to-back. Read the label!
Once the tub is fully cured, reapply fresh caulk around the edges.
Reinstall any hardware that was removed earlier.
Wipe down the tub & admire your work!
Consider replacing your tub if:
❌ It has deep cracks or holes.
❌ Rust spots keep growing despite refinishing.
❌ The structure feels weak or unstable.
For small chips or cracks, use a tub repair kit instead of full refinishing.
For extensive damage, it might be time for a new bathtub installation.
