How Bathtub Refinishing Works

Refinishing a bathtub, also called reglazing, surface resurfacing or re-enameling is a process to renew the bathtub’s surface. The result is a bathtub that looks and feels like new again. Refinishing a bathtub can be expensive, but it is well worth the investment if you are considering this type home repair. Here are the steps involved in bathtub refinishing:

How to refinish a bathtub

The tub must first be cleaned before he can refinish it. Once the tub has been cleaned, he applies an alkaline emulsifier, commonly used to strip wax from floors. Then he uses an acid-based citric cleaner followed by denatured alcohol. Once the bathtub is clean, he applies the emulsifier to the surface.

The tub should be cleaned thoroughly. A chemical bathroom cleaner can be used along with a toothbrush or cloth. The chemical cleans the surface of built-up dirt and soap scum. By scrubbing thoroughly, the tub is prepared for the refinishing agent. Next, he applies three coats with the new finish. Then he cleans up the bathtub. Then re-caulk the bathtub to seal any debris.

You will need the right tools once the bathtub has been cleaned and is ready to be refinished. Prepare the space by removing all caulk. Cover surrounding surfaces with a plastic sheet. Next, prepare the bathtub for refinishing by scraping off any existing coating. You should ventilate the space. A window or industrial fan can help remove any excess fumes. To remove any caulk from your bathtub, use a silicone digester. Failure to do so will ruin the reglazing job.

Cost of Refinishing your Bathtub

Refinishing a bathtub can be costly, but it is much less expensive than replacing it. Refinishing a bathtub can be as low as $75-85% cheaper than replacing it. Refinishing may not prove necessary if the tub is severely damaged. However, reglazed tubs can last 10 to 15 years. The second coat should last for at least five more years. The extent of the damage will determine how much bathtub refinishing costs.

A professional is the best person to perform bathtub refinishing. While you can purchase a bathtub refinishing kit from a hardware store, you should consider hiring a professional. The kits don’t use the same technology, and may look painted. You will need to remove the metal before you can apply the new finish. A DIY project might also involve disassembling the tub to fix its plumbing.

Time frame of the Job

Depending on the refinishing method chosen, your bathtub could take anywhere from two to four hours to be completely refinished. It will take anywhere from 24 hours to 48 hours to dry. The new finish should last between 10 and 15 years. Once you have chosen your refinishing method, be sure to follow all instructions and allow the bathtub to cure for at most 48 hours.

While bathtub refinishing may be a great option for a very old tub, it doesn’t last as long. While older tubs are usually made of higher-quality materials, they tend to have more character. In addition, reglazing may be less expensive and less dangerous than replacing the tub. If the tub is in a state of severe disrepair, a professional service may be better suited for the job.

Products used in Bathtub Refinishing

There are many types of bathtub refinishers available, including one-step and double-step epoxy coatings. A single-step epoxy coating is ready-to-use and requires no preparation prior to application, while a two-step version requires mixing the hardener and resin before applying. Several finishes are available for tubs, but some have greater durability than others.

Many refinishing products can contain isocyanates. These are dangerous to the skin, mucous membranes and eyes as well as the respiratory tract. Exposure to isocyanates can cause respiratory irritation, hives, and skin rash. Some chemicals used in bathtub refinishing can cause cancer or allergic reactions. Hiring a professional is the best way to avoid these dangers.

Polyurethane is a popular product for bathtub refinishing. It is durable and lasts a long time, making it the best choice for bathtub refinishing. While polyurethane is often used, water-based versions aren’t nearly as effective and don’t last as long. The traditional oil-based polyurethane, however, is the best choice for bathtub refinishing. It is also the most reliable.
