Complete Guide to Bathtub Surface Restoration (Refinishing)

Even a high‑quality cast‑iron or steel tub dulls over time: hard‑water scale, hairline cracks, yellow stains, and chips from dropped objects appear. Full replacement is expensive and messy—tile must be demolished, the heavy shell carried out, and plumbing adapted. A smart alternative is surface restoration (refinishing). When done correctly, it restores factory gloss and lasts up to 10 years.

Key Refinishing Methods

  1. Pour‑on liquid acrylic ("poured tub" method)
    • A thick 2–4 mm layer is poured over the rim and flows downward.
    • Creates a durable glossy coat that hides minor defects.
    • Full cure in 48 hours.

  2. Two‑part epoxy spray
    • Applied professionally with an HVLP gun.
    • Film thickness 0.5–0.8 mm, hardens in 12–24 h.
    • Ideal for complex shapes or custom colors.

  3. Acrylic‑urethane rattle cans (DIY)
    • Sold in hardware stores but lasts only 1–3 years.
    • Thin layer; hard to apply evenly without runs.

Takeaway: For long‑lasting results, choose liquid acrylic or pro‑grade epoxy spraying—both services we provide turnkey.

Professional Refinishing Steps

  1. Room prep
    • Mask walls and floor with paper; remove faucet and waste‑overflow set.
    • Run a HEPA‑filtered blower to keep solvent fumes from migrating.

  2. Deep cleaning
    • Alkaline degreaser cuts soap and oils.
    • Acid wash dissolves lime and rust.

  3. Mechanical etching
    • Sand to a matte finish with 120–220 grit; adhesion rises 3–4 ×.

  4. Chip & crack repair
    • Fill with epoxy filler, level with a blade.
    • Re‑sand patches flush after cure.

  5. Acid etch‑primer
    • A micro layer opens enamel pores and doubles as primer.

  6. Top‑coat application
    • Liquid acrylic—slow, continuous pour 2–3 cm wide.
    • Epoxy spray—three cross‑coats with 10 min flash time.

  7. Finishing & cure
    • Infrared lamps speed polymerization.
    • Remove masking, reinstall hardware with new gaskets.

Service Life of the New Finish

  • Liquid acrylic: 8–10 years with proper care.

  • Pro epoxy spray: 6–8 years.

Shorteners: abrasive powders, suction‑cup bath mats, water hotter than 150 °F / 65 °C.

Care After Refinishing

  • Clean with a soft sponge and pH‑neutral liquid soap.

  • Avoid chlorine bleach and metal brushes.

  • Do not fill with very hot water during the first 72 hours.

Refinishing vs. Replacement

  • Save up to 70 % compared to a full remodel.

  • One‑day job instead of a week of demo and tile work.

  • Minimal debris—no bulky cast‑iron to haul away.

  • Custom décor: pick any RAL shade; add anti‑slip zones.

Common Myths

  1. “The new coating will turn yellow anyway.” Modern products have UV blockers; discoloration occurs only with overheating or harsh chlorine cleaners.

  2. “You can’t use a shower caddy afterward.” You can, if the feet have silicone pads.

  3. “An acrylic liner is always better.” Liners cost more, shrink usable space, and can trap water between layers.
