Repairing A Hole In The Enamel Of Your Bathtub

Bathtubs made from metal and covered in porcelain enamel are a very durable, popular choice. These tubs can last for decades, but along the way, they might sometimes develop a little hole or two in the enamel. It's important not to ignore such holes. Even though they might seem like a minor defect, the holes expose the iron beneath to water, which can result in the formation of rust. Luckily, you can fill in small holes in the enamel yourself if you follow these tips.

Step 1: Prepare the hole.

Grab some steel wool or a wire brush, and give the hole -- and the area immediately surrounding it -- a good scrub down. Your goal here should be to remove any rust that has formed on the exposed metal while also roughening up the edge of the enamel left behind so that your new enamel coating sticks to it more readily.

When you're done scrubbing or brushing, wipe down the spot with a damp cloth. Then, pat it dry with an absorbent towel.

Step 2: Prepare your epoxy.

Ideally, you should purchase an epoxy that is made specifically for bathtubs. However, an all-purpose one on the color or your tub's enamel will be okay in a pinch. You'll need to mix the epoxy with the hardening agent in a 1:1 ratio. So, if you use a teaspoon or hardener, also use a teaspoon of epoxy. 

Step 3: Drip the epoxy into the hole.

Use a small paintbrush to pick up some of the prepared epoxy resin. Then, drip it into the little hole in the porcelain. Keep dripping until the epoxy is raised just slightly above the level of the surface; it will flatten a little bit as it hardens. Then, leave the epoxy alone -- and make sure all of your family members know not to touch the epoxy or use the shower for 2 days.

Step 4: Sand down the patch.

After the epoxy has had two days to harden, use some fine-grit sandpaper to sand down your new epoxy patch until it is as smooth as you can get it. Then, give the area one final wipe down with a damp cloth; step back and admire your work.
