Leaky kitchen sink pipes.
Unfinished particle board cabinet floor, MDF sides.
Shelf liner wudn't 'dat good.
Soaked particle board cabinet floor.
Dried out with fan and light bulbs.
Sanded off punky particle board with ROS.
Cabinet floor is mostly smooth and dry with some small patches
of dry but rough and a little punky PB.
Replacing cabinets is NOT an option just now.
What is best solution and prophylactic action? I'm thinking
of sealing the particle board and MDF with something (shellac, wood
preservaticve, &tc,. ???), then coating with a primer (Kilz?), then
painting with a quality oil-based paint.
Again, thanks a heap,
Go to Sam's or Gordon's or whatever local place sells restaurant
supplies to the public. Buy 1 or 2 or those gray plastic tubs they sell
for busboys to use, whatever combination they have that will fit through
the doors into your cabinet. Put them under the drip points for sink.
Added advantage- you can fill them with cleaning supplies, and when
those leak, they will not soak into the cabinet floor either. You can
also slide them out like drawers to reach the stuff in the back. If the
busboy tubs are too big for your cabinet, plastic wash tubs, catbox
pans, etc, come in other sizes and would also work.
The best solution: Replace the bad MDF with plywood. I've done this
several times for people, and it usually takes a couple of hours. Cut
the old stuff out with a reciprocating saw; replace the bad supports
underneath (trust me, they're bad), glued and nailed in place; put in
replacement floor, glued and nailed. The new floor will have to go in
in two or more pieces. Sand, prime, and paint. Use a good gloss paint.
Next best solution: Use wood putty on the rough parts. Sand, prime, and
paint. Cover everything with heavy shelf liner.
OK solution: Put a new piece of plywood on top of the bad MDF. Sand,
Probably just get it smooth, mabye give it a coat of exterior paint if
it's real bad, and cover with shelf liner. Or if you want a better
result with more work, you can go buy a sheet of veneer cabinet
facing, make a template and glue in place. Will likely have to be in
more than one piece though to get it in
Good you didn't start a fire with light bulbs
Punky? Crumbled? Bulging?
Saw dust + water soluble glue = particle board. Dissolve glue and you
have sawdust. If the defects are small, just mix up some Elmer's Wood
Glue, a little water and some crumbled particle board or sawdust. Wood
filler works fine.
Shellac is one type of primer, for certain coatings. Don't
over-engineer a simple task. Prime with your favorite brand of primer
intended for bare wood. Caulk joints and openings with paintable caulk
so future leaks don't penetrate the ends of the panel. Paint two or
three coats of alkyd, being sure that each cures .. you don't want to
put stuff back in before the paint cures.
FWIW, Kilz is a BRAND NAME - I think everyone thinks "Kilz" because it
got to be the most popular stain-blocking primer. I have used several
types of Kilz, as well as other brands. If I need primer, I generally
get same brand as my favorite paint.
If the p.b. is dry, largely intact, and properly painted, it will last
another 100 years.
We had our kitchen "redone", with new doors and drawers and facings on
frames. The cabinets are 40 y/o, built in place 3/4" ply - we couldn't
afford same quality for replacement and there was nothing wrong with
interiors other than wear. Sanded and painted interiors (who looks at
inside of the cab. when it is full?). Just a couple of months after
paying beaucoup $ for the work, our kitchen flooded from burst washer
hose. Quick work with a wet vac and squeegee nozzle kept the cabinets
from being damaged by the water, which got to about 1" deep in places.
I keep an old towel laid down inside cabinet under the sink to catch
drips - no leaks, and if there is something more substantial I want it
to be evident.
I like alkyd paint for kitchen and bath - greasy dirt and spills soften
latex paint too quickly.
over any 15 year period or so, you'll get leaks under the sink for
rusting connections etc. I paint my wood inside with a two part epoxy
paint.. -- ps. I'm in the epoxy business so just grab some from the
shelf. --- paul
I like using a piece of scrap vinyl flooring in the bottom of cabinet
to make it more water resistant. Of course, it won't hold up to a
gallon of water, but is impervious to the little drips.
