A unique thermosetting coating that combines the best
properties of acrylic and urethane. A hard glossy finish
that does not turn yellow, is chemical and abrasion
resistant and will not peel or blister.
DUROKOTE II is an
aliphatic acrylic urethane coating that was developed for
refinishing. 10 Year GUARANTEE that the surface will not
peel or fade.
It should last 30-40 years or
longer! Just like a new porcelain surface. It looks so much
like brand new if you didn't know a refinish had been done
you would not be able to tell.

This is an overview of the refinishing process
Every job is different however there are some basic procedures that
apply
The refinishing material
DUROKOTE II is an aliphatic acrylic urethane.
It is a specialized coating that was developed specifically for this refinishing process.
It contains no free isocyanides. This is important because free isocyanides will 'off-gas' or release from a coating for months and are very toxic.
It self cures under normal room temperature, is self leveling, has the look and feel of natural porcelain and is very stable.
It will not fade, yellow or oxidize as an epoxy or polyurethane (which contains free isocyanides) will and therefore become brittle.
The process - There are three basic steps in a refinishing project
First - Surface preparation
The caulking is removed; trim hardware and drain shoes in bathtubs are removed.
The surface is cleaned with a special cleaner if necessary. An acid solution is
used to etch porcelain to make the surface very porous. Etching your bathtub is absolutely
necessary. Click here to find out why we etch your bathtub
Sanding to abrade and completely clean it is next. A high
quality filler material is used to fill any chips or damaged areas and is sanded smooth.
Second - Masking and final surface preparation
The entire area is masked off with professional grade paper,
plastic, and tape to protect the adjacent areas from the spray
operation. This looks like a spray booth or a "clean room". Chemical
bonding agent is applied; this is an adhesion promoter that will
cause a bond at the molecular level, a 'covalent bond' where the surfaces will actually share an electron!
It is an amazing chemical that really works!
Then the surface is cleaned with tack cloths.
Third - Refinishing material is applied
Twelve to eighteen layers of DUROKOTE II are applied using High Volume Low Pressure spray equipment.
This equipment is high technology and will not create air pollution through the atomizing of finish material under high pressure.
In fact it does not even make over spray! I use an industrial blower with 60 feet of hose attached to draw a large volume of air out of the masked enclosure. This creates a negative air pressure in the
masked area so the spray operation is completely contained and will make absolutely no mess.
The masking is removed (in most cases) before we leave.
Cure time - The refinished surface must dry and harden for 4
hours
This gives the coating time to become hard and to fuse into the original surface. And that's it!
You now have a beautiful new bathtub! Your new surface will last for many years and will save the expense of tearing up your bathroom replacing the fixtures.
After 4 to 6 hours you may apply caulk around the bathtub and
reinstall or replace the overflow cover and drain shoe. Use GE
Silicone II / One Hour Cure Caulk and you can use your bathtub the
same day!
Work completion time
Standard and antique bathtubs require 3 - 4 hours
Fiberglass shower units require 4 - 6 hours
Smaller jobs such as sinks or shower pans require 2 - 3 hours
