APPLICATION
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® 2210-PW 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 to 200 square feet per gallon (9.29030m² to 18.5806m² per liter) in enough quantity to obtain a minimum theoretical dry film thickness of 8 mils (203.2 microns) per coat.
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® 2210-PW.
Do not apply more primer to substrate than can be coated with FreedomTuff® 2210-PW 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® 2210-PW using a plural component, high pressure 1:1 ratio heated, spray equipment.
Proportioner Conditions:
- 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® 2210-PW at a between 4 to 6 gallons (15.1416 to 22.7125 liters) per 100 square feet (9.290 m²) to the substrate, to achieve a theoretical dry film thickness of 72 to 104 (1828.8 to 2541.6 microns) over the entire surface.
When FreedomTuff® 2210-PW 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® 2210-PW 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® 2210-PW.
Freedom® Chemical Corporation’s FreedomTuff® 2210-PW has a theoretical dry film thickness of 96 dry mils (2438.4 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.
TESTING
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).
The FreedomTuff® product line is a revelation of what Polyureas, Polyurethanes, Polyaspartics and Epoxies are about. When so many products have been “made” for maximum impact, at Freedom® Chemical Corporation we’ve been content to let our products speak quietly. No need to shout when you have something special to say.
