Start by prepping your tub. Remove old caulk, scrub it thoroughly with heavy-duty cleaner, and repair any chips with epoxy filler.
Next, protect surrounding areas with tape and plastic sheeting, then sand the tub surface to create texture for better adhesion.
Finally, apply your bonding agent and refinish topcoat in smooth, even strokes, wait thirty minutes, carefully remove the masking tape, and recaulk the edges.
Proper timing and technique will produce professional-looking results.
Prep Your Bathtub Surface (Remove Caulk, Clean & Repair)
Before you can refinish your bathtub, you’ll need to prep the surface thoroughly. Start by removing the overflow plate above the drain and cutting out the old caulk. Use a 4-inch wallpaper scraper to ensure clean edges for your new finish.
Next, tackle the heavy cleaning. Scrub your entire tub with a heavy-duty cleaner and scrub pad, getting into those hard-to-reach spots under the soap dish where soap scum and mineral buildup hide. Once it’s clean, repair any chips or cracks with epoxy filler and let it dry completely.
After that, sand the repaired areas smooth and flush. Set up drop cloths and protective coverings to create a dust-free prep area. Vacuum thoroughly, then resand everything until you have a pristine surface ready for refinishing.
Protect & Prime the Tub (Mask, Sand & Apply Bonding Agent)
Now that your tub’s clean and repaired, it’s time to protect everything around it before you apply the new finish. Start by masking surrounding tile and flooring with tape and plastic sheeting. Cover your drain and fixtures so they stay safe during refinishing.
Next, sand the tub surface to create a rough texture that helps the new coating stick. This roughness improves adhesion between the old surface and your glaze. Make sure the tub is completely dust-free before moving forward. Any particles will show in your final finish.
Apply a bonding agent across the entire surface after priming. This step ensures strong bonding and a durable result. Keep your workspace well-ventilated to manage fumes safely throughout the priming stage.
Apply the Refinish Topcoat & Recaulk
Ready to bring your tub back to life. Now apply the refinish topcoat and recaulk your bathtub.
Ready to bring your tub back to life with a fresh refinish topcoat and new caulking.
Here’s what you’ll do:
- Apply the topcoat in smooth, even strokes across your entire tub surface
- Wait about 30 minutes for the glaze drying process to complete
- Carefully remove your masking tape to reveal clean edges
- Recaulk around the tub edges 30–40 minutes after glazing to seal the edges properly
After your topcoat application, allow the full 30-minute post-coat curing time for proper setting. Once dry, peel off the masking tape slowly and carefully. Then recaulk to seal any gaps near tub overflows and edges. Reinstall your overflow plate only after caulking finishes.
