Grainger only has the Green in little sacks, I'm sure other suppliers
have it in the bigger fiber drums and boxes. (tappa tappa tappa) ...
Yup, McMaster shows the Red (Petroleum) and Green (Wax) and a
Biodegradable Tan Soybean Oil based, in 100# and 300# drums. I'm sure
there's a big cleaning supplies house like Waxie near you.
If the floor is sealed & painted or has floor tiles, you get the Green
colored sweeping compound that is Wax based and no sand or grit, and
the Tan is good when you don't want to make more Hazmat. The Waste
Management folks can't complain about putting the Green or Tan in the
Like a lot of commodities, Sawdust and Sand and a little Oil are
relatively cheap - packaging (empty fiber drum, lid, liner bag) and
shipping is most of the cost. Go for the big drum once every two
years, not a small bag every two months. If it's made regionally,
sometimes you can get credit back on a good used drum return.
Unless you get a better deal on a whole pallet of bags at Will Call -
they forklift load, give them an exchange pallet if they want a
deposit, you forklift unload and stick it in the Steel Racking...
I'm betting it can, but they're going to try to sell you some
They don't use brushes, they use circular 3M type greenie pads in various
levels of aggressiveness. Not particularly expensive, but they won't last
long on rough concrete.
Actually, they could sell you an expensive Diamond Stone Disc for a
floor buffer, and you can do your own terrazzo grinding. It's a bare
brush wheel sized for your machine (14" to 18" OD) with a dozen or so
"pucks" of diamond-embedded brass bolted on to grind the floor flat.
Lots of water, and you'll knock the high spots off the sand and gravel
in the floor in short order.
Then you rinse and hand-squeegee the floor to get the worst of the
concrete dust out the back door, and get the rest with your new NSS
NOW you seal-coat or paint the floor, before the oil soaks into the
newly cleaned floor.
No, Joe. It's sand. I used oiled sawdust on concrete once a week back in
1950's when I worked after school in a grocery store. Dust mopped the
rest of the week.
This is oiled sand. We are in the Central Oregon desert when there is
ALWAYS dust settling out of the air. I wanted something to pick up and
hold the dust and something that was abrasive to help keep the concrete
The concrete in both the store and my plant has/had the normal sealing
put on fresh concrete and nothing more. We need clean bare concrete to
control the ESD. All employees wear conductive foot straps on both feet,
as well as wrist strap grounded to the work area or machine. The bare
concrete is conductive enough to drain away any personally generated
Each material has it's place. The amount of oil on the sand is never
enough to transfer permanently to the concrete. I suppose if fresh sand
was left in a pile on the floor long enough, you would see oil, but that
doesn't happen. As soon as the sand picks up dust, it's pretty well
That's the stuff I remember.
I never heard of oiled sand, but OK.
What I saw done at a nearby air base in Mass was to wash and wax the
concrete floors weekly. This depleted the local dust supply, and tended
to keep everything else clean. [The wax wouldn't make much of an
What do you make?
Or, you grind away the surface faster than the oil can soak in?
Actually you do not have to have clean bare concrete. You can buy
I worked at a facility where leg stats were required and after you put
on leg stats you had to use a continuity tester to verify the leg
stats were providing continuity from one leg to the other. As I
remember after the floors were waxed, they were tested for
conductivity, and then there was a monthly check of floor conductivity
to ensure they remained conductive. There were also scheduled tests
of the earth's conductivity and of the lightning masts.
Yes, each employee is required to test the foot stats each morning and
log in the results. A foot is placed on the tester and a conductive push
button switch is pressed. A light shows a good test. Guess it is a
meg-ohm meter. If I work out in the assembly area, I have to do the
same. Then each employee wears a jacket with conductive threads in it,
and then a wrist band is connected to the bench ground. All benches are
covered with conductive rubber matting.
I like the least cost method of controlling static electricity. Besides,
I don't own the building.
We primarily assemble printed circuit boards for various customers in
Oregon. One in California and one big one headquartered in Phoenix, AZ.
They have a final assembly shop about 2 miles from my plant, so, except
for engineering stuff, we work with the Redmond, OR shop.
We do complete box builds for a few customers, as well as repairs and
calibrations for them. We also build a few custom cables.
Most of the work is surface mount with some through hole components.
Most of the work, now, is using lead-free solder because the products
sometimes are exported to Europe.
