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

1. Sweep floor free of debris, dust and dirt.

2. Scrape and remove foreign materials: gum, plaster, paint over-spray, etc

3. Pressure wash floor to clean corners, cracks, & seams, etc. of dirt and debris.

4. 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.

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.

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.
