What is Bathtub Reglazing?
Bathtub
reglazing, also known as bathtub refinishing and bathtub resurfacing,
is basically the process by which an old, worn out bathtub is restored
to a like new condition by applying a new glaze finish over the surface
of the tub. Thus, the names reglazing, refinishing and resurfacing.
The
bathtub reglazing process was developed in the 1950's due to the
inconvenience and high cost of replacing a bathtub. Replacing a bathtub
is not only expensive but it can also be a real hassle. You must deal
with the removal of the old bathtub, breaking tiles and re-tiling. You
may also have to do some plumbing work to replace damaged pipes
resulting from the removal process, and of course, connect the new
bathtub to the existing plumbing. The expenses to do all this this work
can add up to at least a couple of thousands of dollars. And even if
you know how to do the work yourself and are willing to go through the
hassle, a decent bathtub will cost at least $800.00 to replace.
A
bathtub can be reglazed right in your bathroom without disturbing the
existing tiles, fixtures, or plumbing. The process takes about three to
four hours and is ready to use after 24 hours.
There are several
methods and materials used in the process of bathtub reglazing. Many
use an acid solution to etch the tub and then spray on an epoxy primer
and finally an acrylic topcoat. The problem with this system is that
strong acids ( such as hydrofluoric acid ) destroys the surface in such
a way that it continues to break down even after the primer is applied.
This may in turn cause the material to break down with the constant use
of hot water.Some use a chemical bonding agent (wipe on primer) instead
of a spray on epoxy primer. This type of primer is easier and faster to
apply, but the bond created is weaker than the spray on epoxy primer
and it will probably break down withing a couple of years with the
constant use of hot water. Wipe on primers are recommended for glass
only.
The best system to reglaze a bathtub is to clean the
surface thoroughly with a good industrial cleaner; prime the the tub
with a waterproof epoxy primer that does not require etching; and
finally apply an aliphatic acrylic urethane that was specially designed
for the bathtub reglazing industry.
If the process is done
properly, and the bathtub is properly maintained, bathtub reglazing can
be an excellent cost effective alternative to replacing an old worn out
bathtub.
