  • Acrylic Urethane: Known for its flexibility and resistance to chipping and cracking, acrylic urethane is often chosen for its smooth finish and ease of application.
  • Polyurethane: Offers excellent chemical resistance and durability, making it suitable for tubs subjected to heavy use.
  • Polymer-Based Coatings: These coatings are designed for quick curing and a high-gloss appearance, often used in DIY resurfacing kits.

The key resurfacing techniques include:

  • Spray Application: A professional-grade spray gun applies the coating evenly, ensuring a smooth finish and minimal brush marks.
  • Brush or Roller Application: Used primarily in DIY kits, this method requires skill to avoid streaks and bubbles.
  • Sanding and Etching: Prior to coating, the surface is sanded to remove imperfections and etched to ensure proper adhesion of the new layer.

Step-by-Step Process of Bathtub Resurfacing

The bathtub resurfacing process generally follows a systematic approach to maximize adhesion and finish quality:

  1. Cleaning and Preparation: The bathtub is thoroughly cleaned using strong detergents or degreasers to remove soap scum, oils, and dirt.
  2. Surface Repair: Chips, cracks, and scratches are filled with an appropriate filler or epoxy putty, then sanded smooth.
  3. Sanding: The entire surface is sanded down to create a rough texture for better coating adhesion.
  4. Etching: A chemical etching solution is applied to further enhance bonding between the old surface and new coating.
  5. Masking: Surrounding areas such as faucets, drains, and tiles are masked to prevent overspray.
  6. Priming: A primer layer is applied to seal the surface and provide a uniform base.
  7. Topcoat Application: One or more coats of the selected resurfacing material are sprayed or brushed on.
  8. Curing: The coated bathtub is allowed to cure for a specified time, which may range from several hours to days depending on the material.
  9. Final Inspection and Touch-Up: After curing, the surface is inspected for defects, with minor touch-ups performed as needed.
