NOTE: FreedomTuff® 2202 is being utilized in this document as an example only. Mil thicknesses and product types are based on project type and chemicals.
Throughout the application the sanded surface must be clean and dry.
For optimum results proceed with application while air and substrate temperatures are between 32º F (0° C) and 104° F (40° C) 6º (-14.44º C) above the dew point and rising.
Prior to application of FreedomTuff® 2202 precondition both Part-A and Part-B to 75º F (23.88º C) – 80º F (26.66º C) before applying.
The substrate may require more than one coat of FreedomTuff® primer. After selection of primer, mix and immediately pour primer onto the substrate at a rate of 100 square feet per gallon (9.29030m² per liter) to obtain a minimum theoretical dry film thickness of 16 mils± (406.4 microns).
Aggregate the primer with 0.125 pounds of washed, rounded, dry contamination free sand nominal sieve size #30-60.
Excess aggregate must be completely removed before application of the FreedomTuff® 2202.
Do not apply more primer to substrate than can be coated with FreedomTuff® 2202 within eighteen (18) hours of application. If primer is not coated within the allotted time, sand and re-apply primer.
STEP TWO: Fit Part-A with a desiccant drying device.
Apply FreedomTuff® 2202 using a plural component, high pressure 1:1 ratio heated, spray equipment.
- Capacity minimum 20 lbs. per minute
- Static pressure 2800 – 3000psi
- Spraying pressure 2500psi minimum
- Pressure balance 100 variance desirable
- 300 psi variance maximum
- Temperatures preheaters & hose 165º F (73.8889º C) each
Spray apply FreedomTuff® 2202 at 6.5 gallons (2460.52 liters) per 100 square feet (9.290 m²) to the substrate, to achieve a theoretical dry film thickness of 104 mils± (2541.6 microns) over the entire surface.
When FreedomTuff® 2202 is applied in sections, each application must overlap the previous one within 0 – 6 hours by a minimum six (6”) to a neat straight line.
FreedomTuff® 2202 should be sprayed in a smooth pattern, to establish uniform thickness and appearance (crosshatch pattern).
Recoat window is within 0-6 hours of application, if not recoated within 0-6 hours, sand, prime and re-apply FreedomTuff® 2202.
DRY FILM THICKNESS
Freedom® Chemical Corporation’s Guardian-Containment™ has a theoretical dry film thickness of 120 mils± (3048 microns) with primer (sand not included).
SPECIFICATION AND FIELD ASSISTANCE
Contact Freedom® Chemical Corporation for assistance.
Jobsite visits by Freedom® Chemical Corporation’s employees or its independent agents are solely for determining qualification for warranty.
All spilled material, unused contents of containers, empty containers and secondary containment spills/leaks, must be cleaned up and disposed of in accordance with local, state and federal regulations.
See Product Information Bulletins for substrate preparation, packaging, coverage rates, primer, mixing and application information for each product selected.
FreedomTuff® products have a shelf life of 1 year from the date of manufacture, in factory-sealed containers.
Perform an adhesion test prior to starting any coating project.
Substrate adhesion test should be performed seven days after application. All testing should be performed by a qualified testing agency. Freedom® Chemical Corporation is not responsible for testing.
TESTING IS REQUIRED FOR LEAK FREE WARRANTIES
Test the entire surface of the protective liner by spark testing at 100 volts per dry mil of lining thickness as per NACE Standard RPO 18B or ASTM D-1562 (steel) or ASTM D-4787 (concrete).
