The Tub Refinishing Process
First is removing the old caulking, then making sure all the surfaces are clean before acid etching on porcelain tubs. Fiberglass tubs are sanded instead of etched.
Next is protecting the area before etching, then etching. Without doing this step the surface wouldn’t adhere well and most likely peel or flake off after a short time. Some refinishers skip this step.
Next is drying the surface, then marking any chips and filling them with fiberglass filler. After sanding any fiberglass the area is masked off to protect from any overspray and an exhaust fan is set up. A heat lamp is also used in the colder weather.
After tacking the surface removing any dust particles I spray a two-part epoxy primer formulated just for tub refinishing. It has an extra additive for better bonding to porcelain surfaces.
Again, some refinishers skip this step. I don’t cut any corners, so that your refinished tub will last as long as possible.
After a short drying period of the primer the final coatings are applied. I spray three coats of a two-part high solids urethane allowing drying time between coats. This product takes a bit longer to cure than some other products I could use, but I feel the superior durability is worth the extra drying time needed.
I’ve tried some fast-drying finishes but they lack the gloss and durability of the product I’ve used for 20+ years. I use a HVLP turbine spray unit to provide a smooth high gloss finish. I take pride in my work and strive to have every refinished tub look better than new. I take extra care to get the surface as dust free and consistently smooth as possible.
When the surface is dry enough I untape and then normally caulk the surrounding edges of the tub.
The job normally begins around 9 a.m. and we’re usually finished and out of the house by 2 to 3 p.m.
