Vapor barrier coating for particle board

I am going to install some kitchen cabinets. The structural parts are
plywood, front are solid, but most of the rest is particle board. The mfr
calls it something else (furniture board?), but it's plain old particle
board as far as I can tell.

The particle board pieces are cover with something - either laminate or
plastic - except any places that are not visible.

I know of 2 people personally who had dealings with new kitchen cabinets -
one in apt , other in a house - and both suffered allergic reactions to the
binding chemicals - formaldehyde or other.

Going to all-plywood or all-wood construction sends the price to a different
orbit, since this would essentially be doing a 'custom' job. So for cost,
we have to use as standard a material as we can.

My thought is to coat the uncovered surfaces with some kind of sealer -
either a primer or water seal product - to seal in any vapors inside.

Long story, I know.... but 2 questions...

1 - Can someone recommend the best type of sealer? I have seen water- and
oil-based at Home Depot, as well as various primers, etc.

2 - I heard something recently about the govt outlawing carcinogens in
particle board. Anyone know about that?

Whew! That's a long one. (The longer the better. :O)

Thanks.

Bob

If you haven't bought cabinets yet I would check local stores instead of HD
or Lowes. I did and found better quality installed for less money than HD
and Lowes wanted without installation included.

Even if the vapors are safe, it would be a good idea to seal moisture
out.

I've seen lots of cabinets fall apart when the particle board, mdf,
etc gets

wet.

While on a work assignment in Germany many years ago, I was made aware
that the German building code which governed casework, required that
all exposed edges of melamine board ( particle board substrate) be
covered. Presumably for the formaldehyde outgassing problem mentioned
here. The German cabinet makers used edgebanding at that time,

i use a heat activated form of edge banding which can be applied with
an ordinary household iron. I purchase it at a local cabinet makers
supply. Usually these places supply the local cabinet shops with
hardwood veneer plywood,hinges, drawer slides, finishing supplies et
al.The Borgs don,t seem to carry edge banding.

It's not clear whether you're building or buying these cabinets.

If you're buying them, then you should be able to apply a light
wipe-on coat of poly to seal as much of the material as you can get
at. It should help to decrease moisture problems and inhibit
(somewhat) outgassing.

If you're building the cabinets, you might consider substituting a
product like Extira(tm) that uses acrylic plastic as a binder to
eliminate moisture problems and sidestep the outgassing problems
entirely. It looks like MDF, machines like MDF, and eats tool edges
just like MDF - but won't change dimensions more than 2% even when
left immersed in water. I've applied shellac, poly, and Zinser 1-2-3
primer without difficulties.

I should have added: "Heavy like MDF" to the list. I'm not sure about
the relative combustability.

I use it for routed signs. You can see an example by following the

Mix it yourself, Bob. The pre-mixed stuff comes with the risk of it
being too old to work properly. Once mixed, shellac and alcohol begin to
form esters that retard drying and reduce the dried film's water
resistance. Use denatured alcohol (again, buy fresh as it absorbs water
from the air while open and most half-cans that are sitting around
probably contain more water than you'd want) in a ratio of about one
pound shellac flakes to one gallon of alcohol (precision not required).
For smaller quantities, do the math.

It's my opinion that the reason shellac fell from favor a few decades
ago was due to the prevalence of canned shellac that didn't perform as
well as it could because it was too old. That, and the hoopla around
those new polyurethanes led the market to assume that shellac was
old-hat. There's still a prevalent myth that a wet glass will leave a
ring on a shellac finish but that's not true if the shellac had been
freshly mixed. Shellac will, however, soften in the prolonged presence
of distilled spirits (whiskey, et al -- so mop up after that party) and
it begins to soften at about 140F so you can't set a cuppa on it without
a coaster or it will deboss a mug-shaped ring.

Sorry to go on and on but the more I learn about shellac the more I like
the stuff. Good luck with your project, Bob. I think sealing those
panels is a good, healthy idea and I've no doubt that shellac is the
best finish to use.

Good question. Shellac was my first thought also. Anyone have more ideas
as to what kind of sealer would be best?

Also, I looked at water-based and oil-based. I'll have to do the
application in the house, so whichever will dissipate quicker and still seal
good would be best for me.

Shellac has the best vapor-barrier properties of any finish, even the
newer plastic ones. Ten billion lac bugs can't be wrong.

Another approach to this is to "cook off" the chemicals that are outgassing
before the cabinets are brought into the home... The outgassing can be sped
up by placing the cabinets in a relatively hot environment for a while. For
example, an uninsulated closed up garage that gets a lot of sun, or a sunny
"Florida room" that can be isolated from the main home is probably
sufficient for this purpose. The same type of thing can be done to cook off
the chemicals in carpets, polyester fiber fill in pillows, etc.

Another approach is to use forced ventilation to remove the chemical laden
air from the home. An air-to-air heat exchanger is advisable to save on the
"conditioned air" expense.

Look up Multiple Chemical Sensitivity (MCS) and/or Environmental Illness for
more information on speeding up the outgassing process and on how to deal
with internal air pollution in general.

Where's a good place to get shellac for mixing yourself? All I could find
were quarts at Home Depot, but I'm sure they are pre-mixed.

Thanks, Ron. Shellac it is.

Shellac and it's alcohol

VOCs become NBD

I'd probably use 1 lb, maybe even 1/2 lb cut based on how it applies.

YMMV.

BTW, my idea of water based stuff is interior wall paint, just so you
know I'm biased.

Woodcraft, Homestead Finishing, or other better woodworking finish
suppliers. It comes as dry flakes or buttons, which need to be chopped
up for faster dissolving.

Personally, I've been very happy with fresh Zinnser Seal Coat, available
at GOOD paint stores, but not necessarily the big home centers.
