15-gallon kits

(10 gallons part A to 5 gallons part B)

Inspection

Concrete must be clean, dry, and free of grease, paint, oil, dust, curing agents, or any foreign material that will prevent proper adhesion.
The concrete should be at least 2500 psi and feel like 30-grit sandpaper. The concrete should be porous and be able to absorb water.
A minimum of 14 days cured is required on all concrete. Relative humidity in the concrete floor slab should be below 80% (per ASTM F-2170).
Before starting flooring work, test the existing concrete slab to make sure there is no efflorescence or high levels of alkalinity. Alkalinity refers to a high PH reading which means the floor is not neutral.
A high alkaline environment can cause salts to creep up through the cement called efflorescence.
These salts have a tendency to prevent or destroy the bonding of coatings to the concrete.
The most common form of testing is the use of a wide-range PH paper or tape.
Make sure the floors PH reading ranges between 5-9 to ensure adhesion.
The testing of concrete for alkalinity can show the amount of alkalinity only at the time the test is running, and cannot be used to predict long-term conditions.
Calcium chloride tests should be conducted to determine if the concrete is sufficiently dry for an epoxy flooring installation. The calcium chloride tests should be conducted in accordance with the latest edition of ASTM F 1869, Standard Test Method for Measuring Vapor Emission Rate of Concrete Subfloor Using Anhydrous Calcium Chloride.
When running a calcium chloride test, it is important to remove any grease, oil, curing agents, etc. so accurate readings can be obtained. A rate of 15 lbs/1000 ft²/24hr period or less is an acceptable amount of vapor pressure for use of Americrete’s 6300.

Surface Preparation

Prepare the surface by shot blasting.
All expansion joints should be honored.
Cracks should be chased with a diamond crack chaser (approximately 1/4” x 1/4”), swept or blown clean. The surface should feel like 30 grit sandpaper and be porous enough to absorb the primer.
Lightly misting the floor with water can help promote adhesion. Avoid puddling.

Mixing

Mix 2 parts A with 1 part B (by volume) of Americrete’s 6300 together for 3 to 4 minutes with a slow speed drill mixer.
For best penetration into concrete, thin by adding up to 1 quart of acetone to each 1.5-gallon kit.
The thinned material must be applied at less than 5 mils (and not puddle) to cure properly.
The Americrete’s 6300 will have approximately 20 minutes of working time.

Application

As a primer: Immediately after mixing, spread a strip of the batch onto the surface along the edges where it will be cut in using a brush.
Pour the remaining material near the cut in the area and spread evenly using a trowel or squeegee and back roll using a 1/4” nap non-shedding roller.
The thinned material must be applied at less than 5 mils (and not puddled) to cure properly. Americrete’s 6300 can be applied as an intermediate coat for extra protection from hydrostatic pressure: Mix and apply without solvent at the desired thickness using a notched trowel or squeegee and backroll using a 1/4” nap non-shedding roller.

Drying Time

You may re-coat as soon as the surface is dry to touch or in about 8 hours (but not later than 48 hours).
Lightfoot traffic may be permitted in 24 hours, light vehicle traffic in 72 hours, heavy traffic in 7 days.
All times are based on the average temperature of 70 degrees and 50% humidity. Cooler temperatures will increase drying time.

Limitations

Do not apply at any temperature below 50˚ F or above 95°F.
Concrete must be cured for a minimum of 10 days and have less than 15 lbs of moisture per thousand square feet.
For interior use only unless protected by a UV resistant coating such as urethane.
Epoxy must be cured for a minimum of 24 hours before coming in contact with water.
Concrete should be a minimum of 2500 psi.

When running a calcium chloride test, it is important to remove any grease, oil, curing agents, etc. so accurate readings can be obtained. A rate of 4.5lbs/1000 ft²/24hr period or less is an acceptable amount of vapor pressure for an epoxy flooring installation.
If the reading ranges from 4.5lbs to 15lbs, a moisture barrier system such as our Americrete’s 6300 Primer can be installed to reduce the emissions.

Failing to adhere to these strict guidelines can result in product delamination, discoloration, blistering, or all together failure of the coating system. Testing is the responsibility of the applicator. Americrete bears no responsibility for failures due to any of the above conditions.

Surface Preparation

Over Concrete Surfaces: Shot blasting is the preferred method for preparing the concrete.

In some cases, you may prepare by acid etching, floor scrubbing with a nylogrit brush and water blasting to achieve a clean and uniform surface that feels like 50 grit sandpaper.
If acid etching is done, be sure to properly etch and then adequately neutralize by scrubbing and rinsing several times followed by power washing.
Prepare the surface so that the product will soak in and properly bond.
Over existing Epoxy: Sand the surface with a floor buffer and 50 grit sandpaper, remove debris and wipe with denatured alcohol just before new application.

Mixing

As a Coating: Premix each component separately.

Mix 2 parts A with 1 part B, by volume, into a clean container. Mix thoroughly with a low speed (400-600 rpm) drill motor for 3-4 minutes. Make sure to scrape the sides and bottom of the container during mixing.
The product may be thinned with acetone in which case it must be applied thinly enough to allow the solvent to escape (minimum 300 square feet per gallon).
After mixing is completed, remove from the container within 5 minutes as epoxy will begin to generate heat. Spread immediately onto the floor, as the product is spread out you will have longer working time (10-15 minutes at 70 degrees).

For an Epoxy Mortar:

Mix 2 to 5 parts of a washed and kiln dried aggregate, by volume, to 1 part of mixed Americrete’s 7000 and mix until uniform in consistency.
Application Primer: Prime the surface using Americrete’s 7000 or Americrete’s 6300 Primer.
Do not cut the 7000 back with solvent, as it can cause outgassing. Read individual product information sheets.
Primer coat should be applied thinly and worked into the surface to help avoid pinholes.

As a Coating:

Apply Americrete’s 7000 within 24 hours after the primer coat.
Immediately after mixing, spread a strip of the batch onto the surface along the edges where it will be “cut in”, using a brush or weenie roller.
Pour the remaining material near the “cut in” area and spread evenly using a trowel or squeegee and back roll using a 1/4” nap, non-shedding, or mohair roller.
Use a notched trowel or squeegee to help regulate the thickness and a porcupine roller will help to release trapped air and minimize bubbles.
Depending on the look, thickness, chemical, and abrasion resistance desired, 1 to 2 coats may be applied.
A non-skid surface can be achieved by broadcasting and/or back rolling a washed and kiln dried aggregate into the coating. We recommend the Americrete’s 1402 aggregate or color quarts sand.

For an epoxy mortar:

Prime the area with Americrete’s 7000 or Americrete’s 6300 Primer (no sand added). Within 24 hours, apply the prepared mortar using a trowel.

Limitations

Do not apply at temperatures below 50˚F or above 95˚F.
After mixing completely (3-4 minutes remove from mixing container an apply to the floor)
Do not apply over concrete with Moisture Vapor Emissions above 4.5lbs/1000 ft²/24hr period.
For interior use only unless protected by a UV resistant coating.
Concrete must be cured for a minimum of 28 days.
Solvents added to thin such as acetone will make product combustible or flammable in which case be aware of sparks or open flame.
If the solvent is added, the products must be applied thinly to allow the solvent to escape or proper curing will to occur.

Clean Up

The uncured material can be removed with a solvent. Cured material can only be removed mechanically.
