This is a continuation of my last posting regarding my kitchen
cabinets and how the finish seems to be coming off. Can anyone explain
to me the difference between the different types of finishes that are
sprayed onto cabinets. For instance are some more resiliant than
others. Are some better at dealing with water? I know I don't have
this right, but is there a type of varnish called a catalyzed? and a
non-catalyzed? what is the difference between these two?
I'm just trying to educate myself for the upcominig discussion with my
cabinet guy and my contractor.
<< Can anyone explain

Yes. Some resin films are hard, others softer, more elastic
<< Are some better at dealing with water? >>
Yes. Spar varnishes, for example, are formulated for water/weather resistance,
as are porch floor finishes, etc.
<< is there a type of varnish called a catalyzed? >>
Yes. Some resins may have a catalyst that is activated by exposure to oxygen in
the air. Cobalt naphthenate with alkyds if you want to throw a few buzz words
<< a non-catalyzed? >>
Yes. This would be a type that cures for example, by absorption and reaction
with moisture in the air. Other types may be like epoxies where two reactive
components are mixed together just prior to application. There are others, of
Find out exactly what he used , but honestly he could have just thinned
it out, whatever it was, screwing you and the varnish performance.
The real point is a quality job will not be affected by water drips,
if yours is he screwed you, how or why is not realy important . But the
fact that it needs to be re-done, or re-coated is. Take photos and get 4
or more bids in writing from real pros as to the problem and long term
cure. Quality painters, cabinet and wood finishers are a start. And get
the manufacturers name of the product he used and call the company. My
boat oars, and exterior doors are varnished, boats and wood get
varnished and can last many years, My doors will last 30+ in the shade,
thay have lasted 10 so far and look new. If your kitchen was done right
this would not be an issue for 10-30 yrs. Yes I have refinished alot of
wood professionaly for many years.
By doors I meant cabinet and exterior entrance doors that get rained on
for months and hit with salt and snow in winter, and are fine, the
product I used was 75$ a gallon. Whatever your hack did , and who knows
it doesn`t matter, it was wrong.

There are all kinds of finishes applied to cabinets, even more kinds
than 20 years ago. It can be confusing and there are over 20 distinct
finish properties to consider. The best spray finishes that are
resistant to moisture are catalyzed lacquer (CAB), conversion varnish,
two-package polyurethane, aziridine, carbodiimide, and vinyl laquer.
A catalyzed finish is a crosslinked finish which cures with a chemical
reaction rather than evaporating solvents. This is similar to mixing
up a two-part epoxy adhesive. A non-catalyzed finish will generally
take much longer to cure than one that is catalyzed.

While others have already given you the direct answer to your question,
you should be aware that cabinet manufacturers typically use finishes that
are certified by an organization (the abbreviation starts with an I, I can
not remember what it is) for use on kitchen cabinets. The finish must stand
up to water, cooking grease or oil, hand oil, and heat exposure that one
would expect in a kitchen. You would be surprised at how many hobbyist
finishes do not meet the criteria. They fail way before a kitchen cabinet
Our cabinet manufacturer failed to put a decent finish on the bathroom and
kitchen cabinets. He merely used something like Tung oil..something that
doesn't repel water. The oil finish works fine for the living room and other
places not subject to water, but otherwise is not a good approach. I think a
better finish for bathrooms and kitchens is Verathane. I took all the
cabinet doors and drawers from the bathroom to another cabinet maker. He
applied the verathane finish (not by brush) and they look great. Most
importantly, little splashes from he shower and sink do not harm the finish.
