FREEDOMTUFF® GUARDIAN-ST™ is an integrative group of coatings for stadiums and arenas that utilizes an epoxy primer, instant setting two-component spray applied polyurea and a hand applied two component polyurethane intermediate and polyaspartic top coat that provides an elastomeric waterproof coating with a theoretical dry film thickness between 80 mils± (2032 microns) and 150 mils± (3810 ± microns). These coatings are 100% solids, solvent free and odorless, applied on vertical and horizontal surfaces forming a continuous seamless membrane, primarily used on concrete surfaces. GuardianST™ allows for pedestrian traffic within four (4) hours at 75º Fahrenheit (23.88° C) and 50% Relative Humidity

Case Studies & Applications


  • Chemical resistance – excellent.
  • Complies with VOC and SCAQMD requirements.
  • No noxious odors.
  • USGBC LEED, EQ Credit 4.2 AND 4.3: Low-emitting VOC Compliant Materials
  • Withstands constant water immersion.


  • Stadiums
  • Arenas




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.

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.

Apply coating over primer within eighteen (18) hours, if not coated within the time allotted, contact Freedom® Chemical Corporation.

Do not apply more primer to substrate than can be coated with FreedomTuff® 2190 within eighteen (18) hours of application. If primer is not coated within the allotted time, sand and re-prime the surface then proceeds.

STEP TWO: Prior to application of FreedomTuff® 2190 precondition both Part-A and Part-B to 75º F (23.88º C) – 80º F (26.66º C) before applying.

Fit Part-A with a desiccant drying device.

Apply FreedomTuff® 2190 using a plural component, high pressure 1:1 ratio heated, spray equipment.

Proportioned 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® 2190 at a minimum of 4 gallons (15.1416 liters) per 100 square feet (9.290 m²) to the substrate, to achieve a theoretical dry film thickness of 64 dry mils (1625.6 microns) over the entire surface.

FreedomTuff® 2190 should be sprayed in a smooth pattern, to establish uniform thickness and appearance (crosshatch pattern).

When FreedomTuff® 2190 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.

STEP THREE: Application of FreedomTuff® 4300 must start within 0 6 hours of spraying FreedomTuff® 2190. FreedomTuff® 4300 Part-B should be mixed individually prior to combining, add Part-A to Part-B while mixing, using a mechanical mixer at medium speed making sure not to encapsulate any air. Mix until a homogeneous mixture and color is obtained (a minimum of 2 minutes is recommended).

Apply FreedomTuff® 4300 onto the horizontal surface and spread evenly over the entire surface using 1/8” notched squeegee, then back roll using a ¼ “mohair roller with a phenolic resin core.

On horizontal and vertical surfaces hand apply FreedomTuff® 4300 at 1¼ gallons (4.731765 liters) per 100 square feet, to the FreedomTuff® 2190 in enough quantity to obtain 20 dry mils (508 microns). Prior to its full set and starting to gel, broadcast to refusal a washed, dry, rounded, contamination free 20 x 40 nominal sieve size sand (0.0331”/.850 millimeters, .0165”/.425 millimeters) with 6.5 Moh’s minimum hardness into the FreedomTuff® 4300. If shiny spots appear this area must be sanded, re-apply FreedomTuff® 4300 and sand.

Excess aggregate must be completely removed before application of the FreedomTuff® 4000.

FreedomTuff® 4000 onto the horizontal surface and spread evenly over the entire using a flat edge squeegee and then back roll using a ¼” mohair roller with a phenolic resin core.

Recoat window is within 18 hours of application, if not recoated within 18 hours, sand and re-prime the surface then proceed with recoat.


Freedom® Chemical Corporation’s Guardian-ST™ coating without sand is a theoretical dry film thickness of 80 mils± (2032 microns) and 150 mils± (3810 ± microns).

All spilled material, unused contents, 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.


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).

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.

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.
