Bathtub Finish Failure Be Informed
I have been asked many times in my 34 years as a coatings developer about bathtub refinishing, bathtub glazing, and tile refinishing. Let me start by saying that there is no difference between bathtub finish and bathtub glazing, they are the same thing. The main question people ask is “does it work?”.
The answer is yes and no. The failure and success of the Bathub finish depends as much on the skill of the people as it does on the quality of the product. The people part is about whether the technician has any real tried and tested experience. When it comes to a franchise operation, you will often find that the technician has probably gone through a crash course in the process and it is very difficult to learn everything there is to know and also master the physical application.
I like to compare the process to someone taking a crash course to “learn to drive a car.” The individual can probably learn to drive a car in no time, but would you trust the novice to drive his family cross-country?
This seems a bit dramatic for an example, but considering what the bathtub refinisher is responsible for while refinishing the bathtub in your home, I think it works. Some of the aspects of the finish can have quite serious consequences if not done correctly, so it is important to be informed about the finish of the bathtub before deciding. The technician has to use an acid etching agent to make the tub porous so that the coating adheres to the tub surface. This part of the process should employ a portable ventilation system that expels the fumes outside the house. The etching solution usually contains hydrofluoric, phosphoric or hydrochloric acid. Most of us know that acids can damage other surfaces if accidentally spilled or dripped on them. Another key concern is the potential harm to pets and family if any of the spills come in contact with the skin.
The bathtub painter has to prepare for the application of the restoration coating which is usually sprayed on (I wouldn’t trust someone who claims to use a roller or brush to apply the finish). The coatings are hazardous to breath, and people with asthma or respiratory conditions are highly vulnerable to exposure to these types of materials. Unfortunately, most water-based coatings are not suitable for the humid environment of a bathtub and this leaves the painter with little choice when it comes to coatings that will work.
Types of coatings:
Automotive coatings and primers are generally not the best choice for bathtub refinishing, but they are commonly used and are often re-labeled as “porcelain coating” and primer. The most effective for bonding and wear are high solids aircraft coatings and primers, but these are often the most hazardous to use during application. Epoxies have good adhesion and moisture resistance, but can yellow over time.
Sets:
I personally don’t recommend bathtub refinish kits due to the high failure rate and once they start peeling you have a big problem. Failed finish must be removed before repainting, and if it is done by a professional bathtub refinisher, the overall cost of the job will increase.
The average lifespan of a refinished bathtub is (automotive) 1-3 years (aircraft coatings) 3-5 years depending on usage.
Choosing a bathtub refinishing company – There are several things to consider when deciding which company to use.
How long the company has been in business.
How does the company deal with toxic fumes?
How many bathtubs has the technician who will restore your bathtub repaired?
Get referrals from customers who had their tubs refinished early in the business.
