Why Resurface a Cast Iron Tub?

Cast iron tubs are known for their durability and longevity. However, over time, the surface of the tub can become scratched, chipped, or stained. These imperfections not only detract from the tub’s appearance but also make it more difficult to clean. Additionally, if the surface is damaged, it can be uncomfortable to bathe in, as rough spots or scratches can be felt on the skin.

Resurfacing a cast iron tub can address all of these issues. By refinishing the surface, you can restore the tub’s appearance, make it easier to clean, and create a smooth and comfortable bathing experience.

Materials Needed

Before you begin the resurfacing process, you’ll need to gather the necessary materials. Here’s a list of the tools and materials you’ll need:

  • Gloves
  • Eye protection
  • Respirator mask
  • Putty knife
  • Sandpaper (80-grit, 220-grit, 400-grit)
  • Bonding agent
  • Acrylic urethane finish
  • Paint roller and tray

Step-by-Step Guide to Resurfacing a Cast Iron Tub

  1. Clean the Tub

Before you start refinishing, you’ll need to clean the tub thoroughly. Use a non-abrasive cleaner and a soft cloth to remove any dirt, grime, or soap scum from the surface of the tub. Once the tub is clean, rinse it thoroughly with water and allow it to dry completely.

  1. Sand the Surface

Once the tub is dry, use 80-grit sandpaper to sand the entire surface of the tub. This will create a rough surface that will help the bonding agent adhere to the tub. After sanding, wipe the surface of the tub clean with a damp cloth to remove any dust or debris.

  1. Apply Bonding Agent

Apply a bonding agent to the surface of the tub using a paint roller. Be sure to apply the bonding agent evenly and cover the entire surface of the tub. Allow the bonding agent to dry completely before proceeding.

  1. Apply Acrylic Urethane Finish

Once the bonding agent is dry, it’s time to apply the acrylic urethane finish. Use a clean paint roller to apply the finish to the surface of the tub. Be sure to apply the finish evenly and cover the entire surface of the tub. Allow the finish to dry completely before using the tub.

Tips and Tricks for a Smooth and Durable Finish

  • Use a respirator mask and eye protection when refinishing a tub to protect yourself from harmful chemicals and dust.
  • Apply the bonding agent and finish in a well-ventilated area to ensure proper air circulation.
  • Sand the surface of the tub thoroughly to create a rough surface that will help the bonding agent adhere to the tub.
  • Apply the bonding agent and finish evenly and cover the entire surface of the tub to ensure a smooth and durable finish.
  • Use 220-grit sandpaper to lightly sand the surface of the tub between coats of finish to create a smooth finish.
  • Allow each coat of finish to dry completely before applying the next coat.
  • Apply at least two coats of finish to ensure a durable finish that will last for years.

Other Options for Resurfacing a Cast Iron Tub

While acrylic urethane is a popular choice for resurfacing a cast iron tub, there are other options available. Here are a few alternative resurfacing options to consider:

  • Porcelain enamel: Porcelain enamel is a baked-on finish that provides a durable and glossy surface. It’s a popular choice for resurfacing cast iron tubs and is available in a variety of colors.
  • Acrylic: Acrylic is a lightweight and durable material that can be used to resurface a cast iron tub. It’s available in a variety of colors and can be customized to fit your specific needs.
