Installing an Image 2000 floor coating is a
necessary sequence of steps as outlined below. Follow the outline, taking no
short cuts, and your result will be a beautiful, safe, durable floor coating.
I. Concrete Preparation
A. PRE-PREP
-
Sweep floor free of debris, dust and dirt.
-
Scrape and remove foreign materials: gum, plaster, paint
over-spray, etc
-
Pressure wash floor to clean corners, cracks, &
seams, etc. of dirt and debris.
-
Using 17 floor scrubbers with nylo-grit abrasive
brushes scrub the floor with Simple Green to remove surface contaminants and
excess curing agent.
To scrub floor with detergent proceed as follows: Using the
two gallon sprinkler pails add two cups of Simple Green to two gallons of water
and sprinkle on floor to wet floor completely. Scrub well with floor machine and
immediately rinse with water from hose or pressure washer. Do not let soap dry
before rinsing.
B. PREP AND ACID ETCHING
Acid etching is a critical procedural task, if instructions
are not followed it may negatively
affect the bonding of the coating.
When acid is applied to concrete which is alkaline, the
reaction is very aggressive as the acid literally dissolves the concrete. This
process creates a salt like substance waste product which looks like white dust
and is formed by the acid and the calcium in the cement. This residue must be
removed from the surface while the surface is still wet. If, after applying the
acid to the surface, any portion should be allowed to dry, these salts will
settle into the concrete pores and inhibit the bonding of the floor coating.
Once these salts dry in the pores, they are almost impossible to remove.
C. PROCEDURE/ ACID ETCHING - A
A. Fill 2 gallon sprinkler pails 1/2 full of water then add
acid to fill the pail @ acid water mix is 1:1 Note: Never pour water into acid
always pour acid into water. NOTE: Wear protective gloves and boots and eye
protective glasses as goggles. Muratic acid can give a sever burn to skin or
eyes. If contact with occurs flush with water for 15 minutes.
B. Start with a small area of the floor 10 X 20
section to become familiar with the procedure. Do the floor in sections no
larger than 800 square feet.
C. PROCEDURES/ ACID ETCHING - B
1. Using two gallon sprinklers pails, sprinkle acid on the
floor to fully wet the floor, but not so much as to create puddles.
2. As one person is sprinkling acid have two people
With push brooms spread the solution so that acid is evenly distributed over
the surface of the floor. Keep the acid/water mixture moving with the push broom
for about 5 minutes. The acid reacts rapidly with the concrete and is being
neutralized by the concrete. Because of this reaction process the broomers must
spread the liquid immediately and continually upon contact with surface. After 5
minutes repeat the above process with one half as much acid solution being
applied to the floor.
3. Immediately after the two 5 minute applications of the acid, remove the
scale as follows: using method #1 preferred method Using a high pressure
roto scale cleaner, clean the floor of the scale. You will usually be able to
determine how slow to move the roto cleaner over the floor. If you are going
too fast, you will see residue still on the floor. Usually a very slow
walk is effective. After the floor has been roto cleaned, use the high
pressure wand to remove scale from the edges and corners and rinse the floor
thoroughly with pressure washer. Proceed to your next section and repeat the
process.
After floor has been etched apply Simple Green detergent to entire floor and
rinse of with pressure washer.
4. Method #2, Using a hose flush the acid application area with water and
rinse off loose scale. Then apply Simple Green detergent to area and scrub
thoroughly with the floor machine. While the scrubbers are moving have someone
follow rinsing immediately behind the scrubbers. NO NOT ALLOW DETERGENT OR
ACID RESIDUE TO DRY BEFORE IT IS RINSED OFF FLOOR.
Use the pressure washer to remove soap, and residue from corners and cracks.
5. Dry the floor with squeegees going over the surface. Vacuum the cracks,
corners and holes. Allow the floor to air dry for 10 to 16 hours, or until it
is visually dry. Tape a 4 foot by 4 foot piece of plastic over floor for one
hour before coating, if dampness appears under plastic, floor is still too wet
to coat.
II CONCRETE PATCHING
Cracks, chips, and seams can be filled and patched with #890 epoxy as
follows:
1. Using a soft bristle broom and #30 graded sand, back
fill seams and cracks. Using the broom push the sand over the crack or seam
and then broom out excess so that the crack or seam is filled to within 3/8
of the floor surface.
2. Product mixing #890 is a two component 100% solids
epoxy. Once Part A and Part B are mixed you have 15 to 20 minute pot life, then
mixture becomes too hot to use.
Mix small amount to start to determine how fast you are using
it.
Mix product as follows:
Use a separate container as a mix pail.
1. Stir part A
2. Stir part B
3. Measure out (by volume) one part B and two parts
A. Put these into the mix pail and mix with drill and mix blade for
three minutes at slow speed.
NOTE: For filling cracks add two cups of mortar clay to
I/2 gallon of mixed A & B and mix with drill mixer until mortar clay is
evenly mixed.
For filling chips and sprawls product can be used as is.
4. Immediately pour the mixed product into the plastic
application bottles (ketchup bottles) and apply the product.
For chips and sprawls squirt product into divot until full,
then using a trowel, smooth the edges.
For cracks, apply a bead of 890 into and over filling the
crack so an excess sits on the surface. Wait one half hour and scrape excess
from the crack with a steel trowel.
Note: It takes about 8 hours at 70 degrees F. for the
patches to cure enough to prime over the top. The patches may still be slightly
soft when you prime but should be tack free.
III COATINGS APPLICATION
For clarity of the writing, the procedures for mixing and
application of the coatings have
many common elements which are listed below.
1. Product Mixing (General Instructions)
All three products (the #1200 primer, the #UL104 base coat
and the CRU
aeroplate urethane) are two-component products requiring mixing of an A
component and a B component to make the final product.
Mixing procedures are as follows.
A. Use a separate pail as your mix pail @ 5 gallon
plastic pail.
B. Prior to combining the A and the B stir well or mix with
drill blade mixer the A and the B, as solids in each component settle to the
bottom.
C. Once the A and the B have been premixed, pour the correct mix rate of
A and B into the mix pail and mix for 5 minutes at a medium speed with the
drill blade mixer. Do not whip the product or mix too fast as to draw air
bubbles into the product.
D. Once the A and the B are mixed together the product has a pot life @
use time before it goes hot and cannot be used. Also, brushes and roller
skins cannot be reused.
Once the A and the B are mixed, you have the following time @ pot life to
apply the product so only mix what you can use immediately.
